Product Description

Our threaded hammer fittings use a modular three-component structure, consisting of a male connector, a female connector and a shaped nut, which can be quickly locked by hammering the nut without professional tools, and the original intelligent sealing system is suitable for all kinds of low-, medium- and high-pressure environments, as well as acid environments, which are widely used in oil drilling, natural gas transportation, chemical equipment, and support butt-welding, socket-welding, NPTS threads and other end connections, and can be matched with extensions (300mm/450mm) to achieve the depth of up to 2 meters. Support butt welding, plug welding, NPTS threads and other end connections, and can be used with extensions (300mm/450mm) to realize pipe extensions up to a depth of 2 meters.

Common models:

Material: the main body is made of AISI 4130/4140 forged steel, low temperature impact toughness up to -46°C, special scenarios will be used 316L stainless steel (Cl- corrosion resistance) or duplex steel (acid gas)

Technical advantages: vacuum brazing process (1,120°C) to improve carbide tip wear resistance, two-step heat treatment process to ensure a balance between hardness and ductility.
