3000# 6000# Forged Carbon Steel High Pressure Union With SW Ends
High pressure forged Union ANSI B16.11: This type of pipe fitting is almost similar union to coupling in terms of functions, but just with a difference, i.e. a union can be removed easily any time while the coupling cannot. A variety of dielectric unions are used to join pipes made of different materials to avoid any kind of galvanic corrosion between them. These pipe fittings comprise of a nut, female and male ended threads.

General Note: Dimensions are in millimeters.
Forged high pressure fittings are commonly used in a variety of industries and applications involving high pressure fluid
or gas systems. Some specific applications and uses of forged high pressure fittings include: Oil and Gas Industry,
Power Generation, Chemical Processing,Pharmaceutical industry, Water Treatment, Mining and Construction,
Aerospace and Defense HVAC and Piping
Forged high pressure pipefittings here mentioned below are only a few of those covered by B16.11 standard. The physical
and chemical values indicated correspond to the latest issued standard, although they are affected by modifications
year after year, so we suggest to use them only as a guide.
