Weld Neck
- Detail
-
The Weld Neck (commonly referred to as Weld Neck Flange or Weld Neck Elbow, depending on the fitting type) is a premium pipe component engineered for high-pressure, high-temperature, and critical-service piping systems. Its defining feature is a long, tapered "neck" that extends from the fitting body and welds directly to the pipe end—creating a continuous, seamless connection that distributes stress evenly across the joint. Unlike slip-on or threaded fittings, the Weld Neck design eliminates weak points at the connection, making it ideal for applications where leak prevention, structural integrity, and resistance to extreme conditions are non-negotiable, such as oil and gas transmission, chemical processing, power generation, and offshore engineering.
Flanges: 1/2" - 48" (imperial); DN15 - DN1200 (metric)
