, process introduction
Steel pipe
after pickling
, cold rolling, cold drawing
, and then use advanced high-temperature heat treatment technology (state) to produce steel pipes with bright, smooth surfaces, high precision, and high finish. There is no oxide layer on the inner and outer walls, high precision on the inner and outer walls, and the mechanical properties are suitable for bending at any angle. And it can withstand high pressure, cold bending without deformation, flaring, flattening, tensile and other requirements, and achieve the advantages of cold bending of steel pipes without bursting, no cracks, and no oxide layer on the inner and outer walls.
Main Features
The precision steel pipe produced is a seamless pipe after precision cold drawing
It is made by anaerobic tempering treatment to eliminate surface and internal stress, and then phosphating and anti-rust treatment. . The product has high dimensional accuracy, good ductility, and is easy to be processed and bent into various required shapes without the pipe cross section shrinking or flattening. The pipe has high surface precision and moderate surface hardness after oxygen-free tempering treatment, and is easy to connect with ferrules. , the inner hole and surface are phosphated and rust-proofed, and can be installed directly without pickling and rust removal.
Main specifications
The specifications of the product are outer diameter and wall thickness, which can be customized according to customer requirements. The length is fixed in meters (except custom-made). The delivery status is (normalized), (annealed
), (stress-relieving annealed).
, main materials
The main materials used are,), ,wait. Bright precision seamless steel pipes can be phosphated, plated with colored zinc (yellow zinc) or white zinc according to customer requirements, and the length is within meters.
, Main uses
The company's products are widely used in piping for hydraulic systems, injection molding machines, hydraulic presses, shoemaking machinery, hydraulic equipment, high-pressure oil pipes, ferrule (steel pipe) joint connections, rubber machinery , forging machinery, die-casting machines, engineering machinery, sanitation vehicles, automobile industry, shipbuilding industry, metal processing, military industry, diesel engines, internal combustion engines, air compressors, construction machinery, agricultural and forestry machinery, etc. Shenzhen Baoan phosphating precision hydraulic seamless steel pipe, Shenzhen Shekou ship hydraulic system special pickling phosphating hydraulic precision seamless steel pipe
