Pipe Nipple-TBE,TOE,PBE,Swage Nipple
What is a pipe nipple?
A pipe nipple is one of the most popular category of forged pipe fittings.It is a fitting that consisting of a short straight piece of pipe,and with male threads on both ends or one ends to connect two/one other female threaded fittings or pipes.The length of the nipple is usually specified by the overall length of the thread.
Pipe nipples are commonly used as adapters from one connection type to another.Pipe nipples are mainly used in low-pressure piping systems to fit straight end hose or pipe.The working pressure of pipe nipples will vary with the size and construction of the pipe,the temperature and the product being conveyed. Pipe nipples are available in the widest variety of wall thicknesses and materials in the industry.
Pipe nipples are fabricated by cutting a specified length of pipe and applying the desired end connections.The pipe nipple dimensions and material follow from pipe specifications based on ASME B16.11 standard or MSS SP-95 standard.Pipe nipples come in seamless,threaded,grooved, barbed,bended or welded construction.
Types of pipe nipples:
Thread Both Ends Niple-TBE Pipe Nipple:
A TBE pipe nipple is a nipple of thread both ends,it means this nipple has two male threaded ends,it can connect with two pipes or fittings with female thread ends.It is the most common used pipe nipple in the industry piping systems.Sometimes the thread has a specific length in the end,some also has the full thread on the whole nipple.
Thread One End Nipple-TOE Pipe Nipple:
A TOE pipe nipple is a nipple of thread one end,it means this pipe nipple has a male thread on only one end, the other end commonly should be plain end or bevel end.Sometimes it is called half pipe nipple.This TOE pipe nipple can be the joint between a female thread coupling and a butt welding end pipe.
Plain Both Ends Nipple-PBE Pipe Nipple:
A PBE pipe nipple is a nipple of plain both ends,it means this nipple has two plain ends,which no thread at all.Actually it is just a short length of steel pipe.It is used for some special design in piping system.
Swage nipple is also called reducing nipple.The function of swage nipple is to change pipe’s diameter and to connect two pipes of different sizes.The swage nipple is divided into concentric swage nipple and eccentric swage nipple.Concentric swage nipple is mainly used for vertical pipeline;eccentric swage nipple is mainly used in horizontal pipelines.Common thread swage nipple,divided into double-headed outer thread,single-headed outer thread,flat-headed outer thread.
