A threaded connection is threaded pipe fittings

　　Is a thread pipe fittings threaded connection:

　　Screw thread pipe fittings is threaded connection of a fittings, threaded pipe, also known as is in threaded connection, the threaded connection is through internal and external threads to pipeline and a pipeline, pipeline and screw thread pipe fittings, valves are connected.

　　This cohesion is mainly used for screw thread steel, brass and high pressure screw connection between cohesion cohesion, welding pipe threaded screw machine operation is currently used in the overall situation, and a thread machining accuracy and surface roughness requirements very high pressure pipeline must lathe.

　　Stainless steel threaded pipe fittings:

　　The corrosion resistance of stainless steel decreases with the increase of carbon content, and therefore, most of the carbon content of stainless steel is lower, some steel wC （carbon content） and even less than 0.03% （such as 00Cr12）。 The main alloying element in stainless steel is Cr, so long as the content of Cr reaches a certain value, the corrosion resistance of the steel is only. Thus, stainless steel ordinary wCr are more than 13%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si and other elements.
