​1. Equipment Disassembly​​​​

One of the most common products in the ​maintenance sh​op is a penetrating oil or a multi-purpose spray that is intended to be used to help in the removal of bolts and fasteners.  Ideally, this oil should be highly concentrated and not contain harmful solvents and propellants (some oils have up to 80%). ​  Two Chesterton products meet the highest standard​s of performance and safety.

​2. Assembly & Bolt Tension

Proper gasket and packing seating stress is critical to seal internal pressure, to prevent blowby and to ensure VOC compliance. Bolts must be assembled and tensioned correctly using calibrated torque or tension tools. However often the accuracy of the thread paste / anti-seize is never questioned…yet it should be! 
​
While a K(nut) factor is frequently expressed in the torquing calculations, you should always know the range or accuracy of that value for the anti-seize you are using. While an average K(nut) factor might be 0.16, a scatter of +/-10%, 15% or 20% can create a tension inaccuracy of 20, 30 or 40%.  ​

​3. Sealing for Worn Flanges and Irregular Surfaces

Equipment sealing surfaces worn by corrosion, mechanical abuse, distortion and warpage makes gasket sealing difficult. This is further complicated when the sealing surfaces are dimensionally important such as for line bore equipment (Split Case Pumps, Gearboxes, Compressors and the like).  When deviations exceed the compressive limit of gaskets, leakage can occur and equipment performance is compromised.

In critical industries the use of in-place machining and resurfacing are preferable to gasket dressing, shellacs, or compounds.  While ideal, there are numerous conditions in which the use of a form-in-place gaskets can be used to fill in surfaces effectively.​

​4. Thread and Pipe Sealing​

We are all familiar with off spec, thin, paper like thickness and low density white sealing tape.  Used by wrapping 5 to 8 times, this type of tape can shred, tear and leak.  Often, this tape is replaced with curing pipe dope based on anaerobic sealants. While at first these seem adequate, in service they become brittle and crack under vibration, cannot be adjusted, and in hot surfaces lose 50% of their strength at 250F (120C) service. Leakage of air, oil and seal environmental control fluids are expensive and can impact plant reliability.

​5. Equipment Cleaning and Inspection​

Cleaning and degreasing of critical motor, pump and machinery equipment allows for inspection and repairs to be done more efficiently.  Cleaners should be free of hazardous, toxic solvents without compromising the ability to quickly and safely remove oil, grease, adhesives and other soils.
