Guangxi precision seamless steel tubes dealers manufacturers dealer [Hua Tuo Ka Yip precision seamless steel pipe is a high precision cold drawn or hot-rolled after a steel pipe. Oxide layer precision seamless steel tubes, seamless precision steel inner and outer walls to withstand high pressure without leakage, high-precision, high-quality finish, cold bending deformation, flaring, flattening cracks, etc., so mainly used in the production of pneumatic or hydraulic components products, such as cylinder or cylinders, are seamless. Precision seamless steel chemical composition of the C, carbon, silicon of Si, manganese Mn, sulfur S, phosphorus P, Chromium Cr. 
 The difference between precision steel pipe and seamless steel pipe 
 1, the main features of the seamless steel pipe is welded seam, and can withstand greater pressure. Products can be very rough cast or cold call. 
 2, precision steel pipe products in recent years, mainly within the hole, the outer wall of tighter tolerances and roughness size. 
 Cold drawn precision steel tubes of the characteristics of 
 (1) the outer diameter is smaller. 
 (2) high precision can do small batch production. 
 (3) high precision cold drawn finished, good surface quality. 
 4 steel pipe cross area is more complex. 
 5 steel pipe superior performance, the metal is relatively dense. 
 Implementation of standards GB/T3639 GB/T8713 DIN2391-2 HK15-2000 
 Use for the manufacture of mechanical structure, hydraulic equipment, auto parts 
 Seamless steel pipe specifications :25-610mm wall thickness 4-60mm seamless steel pipe, the company after years of operation has been established with the major steel mills a solid delivery system with the use of the unit has established a good 
 Sales system, the strength of the company, adequate resources, contracts and keep promise, quality and credibility, reputation and development, and low prices to win customers. 

 The specifications of the seamless steel pipe with 

 OD * wall thickness in millimeters, said. Seamless steel pipe divided into hot-rolled and cold-rolled (reversal of) two types of seamless steel pipe. Divided into general steel pipe hot-rolled seamless steel pipe, low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipe, stainless steel, petroleum cracking tubes, geological steel pipe and other pipe and so on. Rolled (allocated) seamless steel Subject to sub-general steel pipe, low and medium pressure boiler pipe, high pressure boiler tube, steel pipe, petroleum cracking tubes, other steel pipes, carbon steel tubes, alloy steel tubes and shaped steel tubes. Generally greater than the hot-rolled seamless pipe diameter 32mm, wall thickness 2.5-75mm, rolled seamless steel pipe outside diameter to 10mm, wall thickness to 0.5 mm, cold-rolled, hot-rolled high dimensional accuracy.
