Sichuan Liaofu Special Steel Industry Co., Ltd has been in steel area for more than ten years,focus on producing 4140 42crmo4 4130 4135 scm440 25crmo4 1010 1020 1045 seamless steel tube,the branch office started in jiangushu on the business of steel pipes
we strictly carry out the quality system iso9001:2000 standard during production process,
adopts advanced modern production management and quality management, to obtain high quality steel pipe . After acid pickling, cold rolling, cold drawn, and then adopt advanced technology for high temperature heat treatment (NBK status) to produce steel pipes with surface: bright, smooth, high precision, high polish, both inside and outside wall without oxidation layer, internal and external wall of high precision, mechanical performance fits well in any Angle bending, and can bear high pressure, cold bending deformation, flaring, flattening, tensile and other require ments, our steel tube doesnot burst when cold bending, no cracks, no oxide layer and the internal and external wall, etc.
The precision steel tube is made by seamless steel tube ,which is through non-oxygen tempering treatment to eliminate the surface and internal stress.The product is of high precision and ductility, easy to be processed into various required shapes, and cross section of the tube will not be reduced or flattened.The surfaceis of high presicion, and the surface hardness is moderate and easy to be connected. The inner hole and surface are treated with phosphating anti-rust treatment without acid cleaning and rust removal.
The company covers an area of more than 8000 square meters with an annual output of more than 5,000 tons.The main products are: cold drawing or cold rolling precision seamless steel pipe and related supporting bright tubing, conveying fluid seamless steel pipe.Our company produce seamless steel pipe in Europe (Germany) DIN series standard is the basic standard, using high quality tube blank, on the basis of this combined with our unique steel pipe manufacturing process,.Steel pipe is produced in high precision and high cold drawn.Because of the special bright heat treatment process, the inner and outer walls of steel tube are not oxidized after heat treatment.

Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration. Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe. Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes. It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.
