The Hy-Lok threaded and welding fittings are precision threaded fittings for instrumentation and process technology. They have high-quality threads for leak-free, safe pipework systems. The outside threads are protected by a plastic cap. Various materials are available, including SS316, brass and carbon steel, as well as a wide choice of threads and configurations.
The fitting material and the material to be welded have to be the same with respect to coefficient of expansion and shrinkage. All socket welding openings have a taper at their ends that ensure a perfect fit as well as correct installation and alignment.
|SS316:||-198°C to 648°C|
