Carbon Steel Pipe Classification

Date:2018-04-27    View:487      Tag:Carbon Steel Pipe Classification
Carbon steel pipe is a hollow reinforcement used to transport large quantities of oil, natural gas, water, gas, steam and other fluids. In addition, bending and torsional strength are relatively light, so they are widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce various conventional weapons, barrels, shells and so on.


Carbon steel pipe classification: carbon steel pipes can be divided into two categories: seamless steel pipe and welded steel pipe. The cross section can be divided into tubular and special-shaped tubes. Round steel is widely used, but there are also square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal steel tube and so on. Water pressure test should be carried out for liquid pressure steel to test its bearing capacity and quality, leakage requirements under pressure, wet pressure or expansion, and some steel water can also be required by standard or demand, curl test, combustion test and flat test.


Seamless steel tube is made of perforated or solid through capillary tube ingot, then hot rolling, cold rolling or cold rolling. The diameter of seamless steel pipe is expressed in millimeter thickness. Seamless steel pipe is divided into cold and hot seamless steel pipes. General hot rolled seamless steel tubes, low, medium pressure boiler tubes, high pressure boiler tubes, steel pipes, stainless steel pipes, oil cracking pipes, steel pipes and other geology. Cold rolling is mainly divided into ordinary seamless steel pipe, low pressure boiler tube, high pressure boiler tube, steel tube, stainless steel pipe, oil cracking tube, other steel pipe, thin wall carbon steel, thin wall alloy steel, wall type stainless steel, special steel pipe.


Welded pipes with plates or strips are bent after forming and then welded. The joints are longitudinally and spirally welded. It is divided into general pipe, galvanized pipe, blow pipe, wire sleeve, public pipe, drum tube, deep well pump tube, automobile tube, pressure variable pipe, welding pipe, welded pipe and spiral welded pipe.
