Nipoflange

What is Nipoflange

A Nipoflange is a branch outlet fitting with an integral flange connection and an extended nipple-style outlet body. It is commonly used when a pipeline requires a reinforced branch connection and a detachable flanged connection at the same time.

Compared with a standard welding outlet, a nipoflange provides easier installation for valves, instruments, equipment, or branch pipelines. Compared with a simple flange connection, it offers better branch reinforcement and a more compact structure.

Nipoflanges are widely used in oil and gas, petrochemical, chemical processing, power generation, refinery, and industrial piping systems.

FAQ

Q: What is a Nipoflange?
A: A nipoflange is a reinforced branch outlet fitting with an extended nipple-style body and a flanged connection end.

Q: What is the difference between Nipoflange and Flangeolet?
A: Both provide flanged branch connections. A nipoflange usually has a more obvious nipple-style outlet extension, while a flangeolet is more commonly described as a flanged branch outlet fitting.

Q: Can Nipoflange be customized?
A: Yes. OD, ID, thickness, outlet length, bore size, bolt holes, sealing face, material, and coating can be customized.

Q: What standards are available?
A: MSS SP-97, ASME, EN, DIN, JIS, and customer drawings are available.

Q: Where are Nipoflanges commonly used?
A: They are commonly used in oil and gas, petrochemical, refinery, chemical processing, power generation, and industrial pipeline systems.
