EN 10025 S235J 20 Inch Hot Rolled Carbon Seamless Steel Pipe

Seamless Steel Pipe
As the name suggests,is a pipe without a seam or a weld-joint. Seamless Steel Pipes is a tubular section or hollow cylinder,usually but not necessarily of circular cross-section,used mainly to convey substances which can flow-liquids and gases (fluids) , supplies, powders,powders and masses of small solids.
Characteristics
1.The thicker the wall thickness of seamless tube, the more economical and practical it is, and the thinner the wall thickness, the higher the processing cost.
2. Its detection and shaping must be handled offline.Therefore, it shows its superiority in high pressure, high strength and material used for mechanical structure.
Type of seamless tube
1. According to different production methods, seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe and extruded pipe.
2. Classification of appearance: circular tube and shaped tube.In addition to rectangular tube and rectangular tube, there are oval tube, semicircular tube, triangular tube, hexagon tube, convex tube, plum tube.
3. Different materials: ordinary carbon structure pipe, low-alloy structure pipe, high-quality carbon structure pipe, alloy structure pipe, stainless pipe, etc.
4. Application: boiler pipe, geological pipe, Oil pipe, etc.
