High Pressure ASTM and AISI Standard Quick Fittings Hammer Union
High pressure union is forged and made of high strength alloy steel with imported world-class technology. Strict heat treatment ensures uniform metallographic structure and bearing capacity in the connector. The materials used fully comply with ASTM and AISI of USA, and the technical indicates of the product with API Spec 16C standard. The product is tight and reliable, and provides easy mounting and dismantling and good exchangeability. The connector of the product allows connection for pipeline thread, oil tube thread and butt weld or pressureless seal end.
The connecting surface of precise linear seal ensures reliable pressure sealing. Application is recommended for low-pressure manifold and operating pressure at maximum 1,000 psi.
With compact construction, this union is widely used on low pressure kill line and in application of air,water, oil or steam with medium pressure. Butt weld Sch.40 is desired for the applicable figure.
O-shape rubber ring is mounted on the seal surface of the male connector for better sealing. Butt weld Sch.40 is desired for the applicable figure. It is recommended for connection of manifold and pipes and for applications with negative pressure and corrosion.
