Lube-Tips - An under-utilized Anti-Seize products during Assembly (Part 2)

Aug 10, 2019
how to monitor compressor oil condition

Why is Anti-Seize So Impotant?
Anti-seize materials and compounds are used on threads, bolted joints and even ACME thread installation. The goal of anti-seize is to prevent the threads from, well seizing and preventing the normal disassembly of the mechanical joint.
 
TWO Most Common Seizing Problems
1) Galling - Cold welding cause the thread damaged
Galling is an adhesive wear that occurs when two metals are in contact and compressed against one another that built up pressure which cause friction. The friction produce heat that enough to weld the metals together. Galling is a potential problem in threaded assembling, for example fastening bolt and nut. This led to the breakage or torn of the thread resulting the bolt and nut to freeze and tighten. 
 
anti seize galling occur on bolt and nut or tapped hole
                             Galling on the thread of bolt and nut 
 
 
 
2) Fretting - Bolt fatigue after oxidation on friction area (due to oscillation)
Fretting wear or fretting corrosion caused when two metals in contact experiencing repeated relative motion by vibration (oscillation) and put under load. The contact movement cause rupture of the material and material transfer at the surface called debris. If fretting occurs in corrosive condition, oxidation on the wear surface will cause corrosion. In normal condition fretting caused the metals to fatigue crack and decrease the fatigue strength of the materials.

Lube-Tips - An under-utilized Anti-Seize products during Assembly (Part 1)

Jul 27, 2019
how to monitor compressor oil condition

What the difference between grease and anti-seize in assembly process? The answer is very obvious, their end product functionality and durability. At extremely high temperature and environment, the bolt or screw joints need a special kind of maintenance from anti-seize. As anti-seize is under-utilized and people don’t understand their purpose, anti-seize somehow be an afterthought solution after you had snapped the head of the bolt or screw that already waste you lots of time.

The purpose of anti-seize is to prevent the bolt or screw threads from well seizing and convert torque to tightening force more efficient. Anti-seize improve the gasket performance, prevent thread from galling and seizure also protect thread from highly corrosive environment. This helps you from wasting lots of money and time to repair also save you from headache. 

There are many types of anti-seize. How you choose your anti-seize is depend on your application. 
 
1) Copper Compound
Copper anti-seize can operate until 1100 oC. Copper is the most favourable anti-seize as it has good corrosion protection. Copper can be applied on all steel except for stainless steel. Copper on stainless steel create an intracrystalline corrosion and cause the stainless steel to crack and break. 
2) Nickel Compound
Nickel anti-seize has excellent chemical and oxidation resistance. This make nickel anti-seize suitable to be used in oil and gas industry. Nickel is a good anti-seize and provide superior corrosion protection on all steel include stainless steel. The maximum operation temperature of nickel anti-seize until 1400 oC.
3) Chrome Compound
Chrome anti-seize has high operating temperature up until 1500 oC. Chrome is the most superior anti-seize and can operate under extreme temperature and enviroment also give good corrosion protection.

Lube-Tips - How to deal with rusty surface

Jul 20, 2019
how to monitor compressor oil condition

Rusting is a redox reaction of the iron and oxygen that forming iron oxide. Basically, rusting will occur in the presence of water (H2O) and oxygen (O2) and those are present naturally. So, the possibility of rusting is very possible.

Rusting give more disadvantages rather than advantages. Rusting tend to vent in technical malfunctions of the machine, it weakens the structure of the metal and cause the safety, health and environmental risk in the plant. Thus, here how you can prevent or remove or slowing down rusting.

1.  Rust Remover
 
Rust remover is a concentrated acid that used to remove the rust on affected area.

2. Anti-rust Oil

Anti-rust oil provides a protection layer to prevent the metal from corrosion and act as water displacing agent. Anti-rust oil has:
  • Medium-term protection against metal corrosion: 1 to 3 months. 
  • Long-term protection against metal corrosion: 4 to 6 months, or longer.

3. Cold Zinc Galvanizing
       
Cold zinc galvanizing is application of the zinc coat on the metal. The zinc coating prevents the corrosive substances from reaching the metal. This method is slowing down the corrosion of the metal as after the zinc at the affected area already consumed, the corrosion on the metal will be occur.

Lube-Tips - About Developer (Dye Penetrant Liquid)

Jun 29, 2019
how to monitor compressor oil condition

Principle of developer
 
The role of developers is to draw the penetrant from the cracks out onto the surface to form visible indication. With visible penetrants, developers provide a white background so that red dye penetrant indications are easy to identify. The penetrant indication is not the actual size of the crack as the penetrant spreads through the developer over time. Specifications state minimum and maximum development times to address the spread of penetrant through developer. The minimum development time should allow enough time for penetrant to be pulled from the surface open flaw and spread on the part surface for enhanced visibility. The maximum development time is in place to minimize excessive penetrant “bleed out” from an indication that could potentially obscure the indication.
 
Types of Developers
1. Dry Powder Developers
Dry powder developers are fluffy white powders that may be applied manually with powder spray bulbs or spray guns or by dipping and dragging parts in the dry powder developer. Dry powder developers deposit a light dusting on the part surface and are only suitable for fluorescent penetrant inspections. Specifications prohibit the use of dry powder developers with visible dye penetrant inspections since dry powder developers would not provide an adequate white contrasting background for visible dye penetrants.

2. Water Soluble Developers
Water soluble developers are supplied in powder form and are mixed with water. Water soluble developers are only for use with fluorescent penetrants. Water soluble developers may not be used with visible dye penetrants because, like dry powder developers, water soluble developers do not produce an adequate white contrasting background that is necessary for visible dye penetrant inspection.

3. Water Suspendible Developers
Like water soluble developers, water suspendible developers are supplied in powder form and mixed with water. However, water suspendible developers do not dissolve in water. Instead, they form a developer suspension. The developer suspension must be continuously agitated to provide a consistent developer concentration. Water suspendible developers may be used with both fluorescent and visible dye penetrants since water suspendible developers produce a suitable white developer coating that enhances both visible dye and fluorescent penetrant indications.

4. Nonaqueous Developers
Nonaqueous developers are supplied ready to use. Spray is the preferred application method for nonaqueous developers, and aerosol cans are a convenient option. Nonaqueous developers contain white powders suspended in volatile solvents and require mixing prior to use. When applied by spray, the solvent evaporates and leaves a dry white developer coating on the part surface. Nonaqueous developers are suitable for both fluorescent and visible dye penetrant inspections.

5. Non-Aqueous Wet Developer Aerosols
Non-Aqueous wet developer aerosols are powder particles mixed with a quick drying solvent. The powder is suspended in the solvent and is sprayed onto a substrate. The solvent evaporates, leaving an opaque white coating and contrasting background for fluorescent and visible penetrant inspections.

Lube-Tips - About Penetrant and It's Dwell Time (Dye Penetrant Liquid)

May 18, 2019
how to monitor compressor oil condition

Dwell Mode Method
The penetrant liquid can be applied in a number of different ways, including spraying, brushing, or immersing the parts in a penetrant bath. Basically there are two types of dwell mode method which is immersion-dwell and drain-dwell. Immersion-dwell is lettling the past immered in the penetrant liquid during the dwell time, drain-dwell is letting the test piece to sit for a sufficient period of time for the penetrant to fill into any flaws and crack. The drain-dwell mode has been shown to produce the most sensitive results. However, there is no harm in allowing a penetrant to dwell longer than the minimum time as long as the penetrant is not allowed to dry on the part.
 

Two Basic Penetrant Materials
Type 1 - Fluorescent Penetrants: they contain a dye or several dyes that fluoresce when exposed to ultraviolet radiation. 
Type 2 - Visible Penetrants: they contain a red dye that provides high contrast against the white develper background. 
 

Dwell Time
Penetrant dwell time is the total time that the penetrant is in contact with the part surface. The dwell time is important because it provides the sufficient time to allow the penetrant to penetrate into the flaws and cracks area. Dwell times are usually recommended by the manafacurer and each formulation are not design to perform the same. It is depends on the size of defects and material. 
 
Penetrant dwell time is the total time that the penetrant is in contact with the part surface. The dwell time is important because it allows the penetrant the time necessary to seep or be drawn into a defect. Dwell times are usually recommended by the penetrant producers or required by the specification being followed. The penetrant must possed a number of important characteristics:-
 
- spread easily onver th eseufrca of the material
- be drawn into surface breaking defects iby capilary action. 
- be highly visible or fluoresce brightly to produce easy to see indications. 
- not be harmful to the matrial being tested or the inspector.

Lube-Tips - How to monitor compressor oil condition

Jun 3, 2018
how to monitor compressor oil condition

As many compressors run in severe environments, here are some point that you might use to monitor your compressor oil condition so that can extend the life of the oil.
 
Total Acid Number (TAN)
The oxidative life of fluid is determined by total acid number (TAN). The weak organic acid that produce as oil oxidize is measured by titration of potassium hydroxide (KOH) that neutralize one gram of oil. The new oil acid number is compared to the used oil acid number to determine the degree of oxidation.
 
Viscosity
Viscosity changes are also monitored to indicate oxidation problems and also the introduction of a heavier or lighter contaminant fluid.
 
pH
Some air compressor operate in corrosive air environment. Thus, pH is good indicator to the acid gases and the depletion of corrosion inhibitors.

Lube-Tips - How to choose the correct grease

May 19, 2018
Davor Specialty Lubricants grease and oil supplier in malaysia

How do you know if you’re using the right grease? For a better understanding, here how can you choose the right grease.

Base oil viscosity
The base oil viscosity for bearings can be calculated using a formula that takes the speed and dimensions of the bearing into consideration.
DN = (rpm) * (bearing bore) and
NDm = rpm * (( bearing bore + outside diameter) / 2)
Knowing the speed factor value (DN/NDm) and operating temperature, the minimum viscosity requirement can be read directly from chart.

base oil viscosity chart
Base oil type
The base oil type is determined by the conditions in which the grease will perform, such as high and/or low temperatures, load and pressure. The load and pressure not only will influence the base oil type but also the additive package (extreme pressure, anti-wear).
 
Thickener type
A good thickener type will be compatible with the equipment manufacturer recommendations and will be able to withstand the conditions under which it must perform.
 
NLGI Grade
Speed factor and operating temperature can be used to determine the best NLGI grade for a given application. Table show general guide to selecting NLGI grade based on speed factor and operating temperature. 
 
Operating
Temperature		 DN (Speed Factor) NLGI No.*

Lube-Tips - Important factors that influence hydraulic oil performance

May 5, 2018


There are several factors that influence the way hydraulic fluid performs, including:
  • Viscosity
  • Wear
  • Corrosion
While the above list is not all-inclusive, it does mention some of the most important factors that can influence hydraulic fluid performance.
 
Viscosity
Hydraulic fluid’s viscosity requirements are determined by the hydraulic system’s load as well as its minimum and maximum operating temperatures. The right hydraulic fluid for your hydraulic system will need to maintain a minimum viscosity even at the hottest operating temperature, but it must not be too viscous to pump at low temperatures.
 
Wear
Wear affects the moving parts of hydraulic systems and occurs when metal contacts metal. A good hydraulic fluid will help reduce wear by lubricating moving parts and providing a thin layer of protective oil.
 
Corrosion
Corrosion of hydraulic system components is usually caused by acidic chemical corrosion, system rusting, or both. A good hydraulic fluid should have rust inhibitors and other additives that protect against corrosion and rusting.

Lube-Tips - How to choose the correct gear oil

May 5, 2018


In order to choose the best lubricant for a gear set, the following criteria must be addressed:
  • Base Oil Type
  • Viscosity
  • Additives

Base Oil Type
Properties Mineral oil Synthetic Polyglycol Ester
Viscosity-Temperature behaviour
normal
 good very good good
Ageing Resistance normal good very good good
Low-Temperature Characteristics poor very good good good
Wear Protection normal good very good good
Friction Coefficient normal good very good very good
Neutrality towards sealing materials and paints very good very good poor poor

Viscosity-Temperature Relationship
A flat VT- curve permits the use of one and the same viscosity of an oil at low and high temperatures.
 
Good ageing and oxidation stability 
These characteristics ensure adequate lubricant service life and use at high service temperatures.

Neutrality towards non-ferrous metals, paints and elastomers
The brass cages of rolling bearings, sliding bearing materials, interior paints as well as the elastomers and plastics which seals and viewing glasses consist of must not be affected by the lubricant. 

 
Viscosity
It is important to understand the methods for viscosity selection and the factors that affect the requirement.
 
The viscosity for a gear lubricant is primarily chosen to provide a desired film thickness between interacting surfaces at a given speed and load. Because it is difficult to determine the load for most viscosity selection methods, the load is assumed and the determining factor becomes speed.

The chart below is applicable to spur, helical and beveled enclosed gear sets. Other charts exist for worm gears and open gearing. To use this method, the type of gear set, gear geometry, operating temperature and the speed of the slow speed gear must be determined.

Determine gear oil viscosity chart based on speed


Additive
Extreme Pressure (EP) gear oils contain special additives that enhance their film strength or load-carrying ability. The most common EP additives are sulfur phosphorous, which are chemically active compounds that alter the chemistry of machine surfaces to prevent adhesive wear under boundary lubrication conditions.
 
In less severe applications, antiwear additives may also be used to provide wear protection under boundary lubrication conditions. 

Rust and oxidation inhibited (R&O) gear lubricants do not contain antiscuff additives or lubricity agents. R&O gear oils generally perform well in the categories of chemical stability, demulsibility, corrosion prevention and foam suppression. These products were designed for use in gearing operating under relatively high speeds, low loads, and with uniform loading (no shock loading).
