Purpose
Purpose
The purpose of this document is to establish the minimum requirements for the use of threaded Pipe Nipples for process piping to include heat trace on Flogistix Compressor packages. This Policy is effective for all Flogistix compressor packages that are being manufactured, maintained, or being contracted to work on by Flogistix personnel. Where the use of threaded pipe is required on any process pressure piping or low pressure systems such as heat tracing, the following Flogistix policy is in place. (Electrical conduit piping is exempt from this policy)
The use of Schedule 80 pipe is the minimum requirement for all process piping applications
The use of All Thread or Close Nipples is prohibited. (See definition below) Flogistix policy is that Close/All Thread Nipples will not be used so that it will eliminate the possibility of the Close/All Thread Nipple from failing at the center point where the to male threads overlap each other.
The use of what is called a Hex is acceptable when a very short length nipple is required for the application (See definition below)
All pipe nipples that are is used must have a portion of the pipe remaining between the two male threads of the nipple
All threads must have some type of thread sealant applied either as Teflon tape or a liquid thread sealant or both.
Any time piping has been installed or replaced, the unit must be pressure tested to insure that no leaks are present on the nipple that was installed or replaced or that any other fitting on the process piping may have been disturbed and and begins to leak. The test pressure must achieve the highest rated pressure that the process piping will be exposed to during operation of the compressor package unless other limiting factors prohibit it.
In any circumstance requiring the shortest possible connection, alternative solutions such as compression (tubing) fittings should be considered. If an all thread nipple is deemed the most appropriate solution, Engineering approval is required prior to assembly.
Close/All Thread Nipple
Shoulder Nipple
Hex Nipple
Nipple Definition: In Plumbing and piping, a nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings. The length of the nipple is usually specified by the overall length with threads. It may have a hexagonal section in the center for a wrench to grasp, (sometimes referred to as a "Hex Nipple"), or it may simply be made from a short piece of pipe (sometimes referred to as a "Barrel Nipple or Pipe Nipple"). A "Close Nipple or All Thread Nipple " has no unthreaded area: when screwed tightly between two female fittings, none or very little of the nipple remains exposed.

Scope
Scope
This procedure applies to all compressor units that are currently being manufactured, maintained, or being contracted to work on by Flogistix personnel and is applicable to all Flogistix employees, contractors, and temporary employees.
Hazards
Hazards
Employees sampling or removing compressor oil from pressure vessels need to be aware of the possibility of Hazardous gas. Employees should be aware that units could contain flammable and toxic gasses. Potential for the possible hazards of gas ignition or fire, hot surfaces & fluids. Risk of possible concentration of H2S. Hazardous gases could be in the units pressure vessels, cooler, or associated piping and risk of inhalation of hazardous gas fumes. Environmental spill of compressor oil and production fluids
Safety
Safety
All Personal Protective Equipment (PPE) for Field Mechanical duties apply for this procedure. Flogistix EHSS Manual, Section 8, Procedure 8.3 Personal Protective Equipment (PPE)
