Introduction of ERW Steel Pipe

Date:2015-07-24      Views:729Time(s)      Label:Introduction of ERW Steel Pipe    

There are three mainly manufacturing processed during ERW steel pipe production, including cold drawn, cold-rolled and hot-rolled. The raw material of the ERW steel pipe includes 10 #, 20 #, 35 #, 45 # which is known as the ordinary steel pipe and the 16Mn which is known as low-alloy steel pipe. On the contrary, the steel pipe made of 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo is usually called as stainless steel pipe. This kind of steel pipe can be divided into several kinds according to the usage of it, for example, the structure seamless steel pipe, seamless steel pipe, boiler seamless steel pipe, pressure boiler seamless steel tubes, chemical fertilizer equipment, high pressure seamless steel pipe, geological exploration with seamless tiles; oil exploration blocks with no pipe joints; petroleum cracking; ship seamless; drawing cold rolled precision seamless steel tubes and various alloys. We can use diameter and wall thickness to represent API seamless. Thick-walled seamless steel pipe is used for many purposes, such as mechanical processing, mining, hydraulic steel.

The ERW steel pipe includes hot-rolled thick wall welded steel pipe, cold-rolled thick-walled welded steel pipe, cold drawn welded steel pipe, and thick-walled welded steel pipe. The welded steel pipe of jacking structure is used in a wide span, for example, it can be used in chemical, petroleum, textile, medical, food and machinery. What is more, the ERW steel pipe can be useful for industrial corrosion resistance because of its special parts and components made of welded steel hot-rolled and cold drawn welded steel pipe. The welded steel pipe used to convey fluid meets the standard of GB/T14976-1994.

The shaped seamless steel pipe is actually one kind of cross-section shape of the API seamless steel tubes. The pipe can be divided into shaped seamless steel pipe wall thickness, wall thickness ranging shaped seamless steel pipe and variable diameter shaped seamless steel pipe according to the different shapes and sizes of the pipe. The shaped seamless steel pipe is suitable for a variety of structural parts, tools and mechanical parts. Compared to the barrel, the ERW steel pipe has a greater capability of torsional bending, which in turn leads to the structural weight reduce and can save steel.
