Stainless Steel Pipe Nipple Types

Stainless steel pipe nipples are a type of fitting commonly used in pipe connections, which are typically welded or threaded to connect pipes.Stainless steel pipe nipples come in a variety of types, with simple structures and small sizes that can be easily installed in various pipes and equipment. They also have good sealing performance, effectively preventing fluid leakage.Stainless steel pipe nipples can meet the needs of different pipe designs, with common types including threaded nipples, swage nipples and hex nipples.

Threaded Nipple：TOE And TBE Nipple.

Threaded pipe nipple is a short piece length of pipe or tube that includes one thread end with plain or bevel end(TOE), or both thread ends(TBE).  The threaded nipple is a relatively important type of stainless steel pipe nipple. In pipeline applications, threaded nipples are both convenient to install and disassemble, and have a variety of specifications to choose from. At the same time, they can withstand high pressures and are suitable for various high-pressure fluid pipelines and equipment, meeting the needs of different pipelines and equipment, so they are cost-effective.In appearance, threaded nipples maintain their surface smoothness, without cracks, obvious pores, inclusions, and other defects, and are durable.Therefore, they are widely used in the connection of various pipelines and equipment.The corresponding production standard is ASTM A733.

Swage Nipple：Concentric And Eccentric Swage

It is used to change the diameter of the pipe and connect two pipes of different sizes. Same function as butt weld pipe reducer.The swage nipple is a widely used type of stainless steel pipe nipple.It corresponds to the production standard American Standard MSS SP-95 and the petrochemical standard SH/T3419.

Hex Nipple:A Special Type of Stainless Steel Pipe Nipples.

It have hexagon shaped section in the middle and male thread on both ends to associate two other pipes or fittings.These threaded hex nipples are available in various sizes and specifications. And the feature is easy for torquing, tightening, loosening, installing by wrench. And also have a good resistance.Threaded fittings come in a variety of sizes and shapes and can provide an effective seal for pipes transporting liquids, gas and steam. They twist onto pipe using various male and female thread connections including NPT or BSP.All types of hex nipples are manufactured and inspected to standard of ASME B16.11 or EN 10242.

Materials

Stainless steel pipe nipples have the advantages of corrosion resistance, high strength, and resistance to deformation, which can meet different usage scenarios and requirements.Stainless steel pipe nipples come in a variety of stainless steel grades, including SS304,SS316/L,SS321,SS347.

In addition to the above common stainless steel materials, there are also special stainless steel materials such as duplex stainless steel and super duplex stainless steel, which are suitable for a wider range of applications.When selecting a stainless steel nipple, it is necessary to consider factors such as the specific use environment, corrosion resistance requirements, and processing technology to choose the appropriate material.
