High pressure Hammer 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.

Hammer Union — Forged, Fig 100 through Fig 1502
Our hammer unions are forged, not cast. Forging keeps the grain flow continuous through the body, so the part holds pressure and resists fatigue far better than a casting — the difference shows up at the seal and thread after repeated make-up and break-out.
We supply the full range from Fig 100 through Fig 1502 — roughly 1,000 to 15,000 PSI CWP — for oilfield, cementing, fracturing, manifold and other high-pressure lines.

How to specify
Tell us the figure number, size, end connection (threaded or butt-weld), medium and working pressure, plus quantity. Material certificates and batch test reports are available with the order.
Quality and testing
Batch test reports are provided with each shipment. Third-party inspection (SGS / BV / TÜV) can be arranged at the factory before shipment.
Note
Seal selection matters more than most people expect — a large share of "failed" hammer unions are simply the wrong elastomer for the medium, not a bad forging. Tell us the medium and we will match the seal.
