The high pressure unions are made from high-strength alloy steel by forging by means of international advanced technologies. The strict heat treatment is adopted to guarantee the joint to have the uniform metallographic structure and bearing capacity.Used materials completely conform to American ASTM and ASI standards, The technical indexes of the product completely conform to API Spec 16c standard. The product is characterized by reliable seal, rapid assembly and disassembly and good compatibility and interchangeability. In addition, the product joint can be connected by pipe line thread, oil tube thread, butt-welded or non-pressure sealed end.
Precision linear sealing surface guarantees reliable pressure seal. They are recommended for occasions where the low pressure manifolds are used and the working pressure is not more than 1000Psi
