Spiral steel pipe(ssaw) is a steel pipe with spiral seam, which is made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in pipeline transportation of oil, natural gas, bridges, docks, roads, buildings and other projects. Welding is the most common connection method for…
Read MoreOil casing pipe is the lifeblood of keeping oil wells running. Due to different geological conditions, the downhole stress state is complex, and the comprehensive action of tension, compression, bending and torsional stress acts on the pipe body, which puts forward higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason,…
Read MoreWhat are the factors that affect the quality of American Standard seamless tubes? 1. Temperature Temperature is the main factor affecting the quality of American Standard seamless steel tubes. First of all, the uniformity of the heating temperature of the tube blank directly affects the wall thickness uniformity and inner surface quality of the perforated capillary, which in turn…
Read MoreThe surface quenching and tempering heat treatment of seamless steel pipes is usually carried out by induction heating or flame heating. The main technical parameters are surface hardness, local hardness and effective hardened layer depth. Vickers hardness tester can be used for hardness testing, Rockwell hardness tester or surface Rockwell hardness tester can also be used. The selection of…
