Threading threading metal hose metal hose (English name: Metal Conduit) made of 304 stainless steel or 301 stainless steel, used for wire, cable, wire and cable protection tube automated instrumentation signal specifications from 3mm to 150mm. With the abundance of metal hose provides ultra-small diameter metal tube (inner diameter of 3mm-25mm) main variety of metal hose (8) feet of the sensor for precision optical line protection, industrial sensor circuit protection, with good flexibility, corrosion resistance, high temperature resistance, abrasion resistance, tensile strength. Hose Fittings category metal hose NPT, PT, G, meaning the difference between metric thread and metal hose nipple contains many types, many people do not fully understand this and are now on these threads comply with some explanation Description: NPT, PT Food metal hose, G are NPT pipe thread is National (American) Pipe Thread abbreviation metal hose, NPT is American taper pipe thread, for sealing. Belong to the American standard of 60 degree taper pipe threads for North America. National standards can be found GB / T12716-1991 PT is Pipe Thread acronym is 55 degrees sealed tapered pipe thread, is a Whitworth thread family, used in Europe and the Commonwealth countries. Commonly used in water and gas pipe industry, taper 1:16 regulations. National standards can be found GB / T7306-2000 G is 55 degrees non-thread sealing pipe thread, is a Whitworth thread family. G represents threaded barrel mark. National standards can be found GB / T7307-2001. G is collectively pipe thread (Guan), division 55, 60 degrees are functional, commonly known as a round tube. That thread processing is made by a cylindrical surface. Metric thread pitch to that, the US and British-made thread with thread count per inch to represent metal vapor hose, which is the biggest difference between them. Metric thread is 60 degrees equilateral tooth type, inch thread is 55 degrees isosceles tooth type, American Thread 60 degrees. Metric threads with metric units, the US and British imperial units THREAD. Pipe thread is mainly used to connect pipes, its internal and external thread closely, there are two straight and tapered pipe. Nominal diameter of the pipe diameter is connected, apparently thread diameter larger than the nominal diameter.
