Product Description

Product Description

 

Seamless Steel Pipe Seamless steel pipe is an engineering marvel, crafted by expertly punching a whole round steel bar, resulting in a surface free of welds, which is why it's called a seamless steel pipe. Based on the production technique, these pipes fall into several categories: hot-rolled, cold-rolled, cold-drawn, extruded, and jacking pipes. Furthermore, seamless steel pipes boast diverse cross-sectional shapes: from round to specialized forms like square, oval, triangle, hexagon, melon seed, star, and even winged profiles. These pipes cater to various demands, with diameters ranging from a substantial 900mm to a delicate 4mm. Depending on the intended application, they are available as either thick-walled or thin-walled varieties. Seamless steel pipes find their essential application in numerous high-stress environments: petroleum geological drilling, petrochemical cracking, boiler manufacturing, bearing production, and in crafting high-precision structural steel for automobiles, tractors, and the aviation industry.
