Hammer striking union fittings connecting matching joints

Union joint is a mechanical component mainly used to connect various manifolds, especially on equipment such as oil drilling pipelines and fracturing trucks. It is suitable for standard and acidic working environments, with a working pressure range from 000 psi to 15000 psi and a specification range of 1 "to 8". The structure of a union joint includes a union male head (ball joint) and a union female head (horn joint), which are connected by fastening wing female joints and sealed with sealing rings. The design of this joint allows for installation and disassembly without moving the pipeline, making it easy to inspect and maintain. ‌

Cast steel and forged steel are common metal materials used for general industrial pipeline connections. ‌

Alloy steel provides higher strength and corrosion resistance, making it suitable for applications that require higher performance. ‌

Stainless steel (ASTM 304/316L) and 1.4301/1.4404 materials provide excellent corrosion resistance and strength, commonly used in sanitary grade fittings and applications requiring high purity. ‌
