4”-1003 High Pressure Union

The international advanced technology is brought into high pressure union, which is made of high strength alloy steel forging. The strict heat treatment assures uniformity of metallographic structure and pressure capability of the joint. The material conforms to ASTM and AISI standard. Its technical performance completely conforms to API Spec 16A. The product sealing is reliable, quick assemble and disassemble good interchangeability. The joint type can be pipeline thread, tubing thread, butt welding thread or press sealing ends.

The models of high pressure union made in our company are as followings: model 100, model 200, model 206, model 207, model 211, model 300, model 402, model 600, model 602, model 1002, model 1003, model 1502, model 2002, and model 2202.
