Pickled and phosphated hydraulic precision seamless steel pipe for ship hydraulic systems, pickled and phosphated hydraulic precision seamless steel pipes for Huizhou Huidong ship hydraulic system, special for Shanwei ship hydraulic system Pickling and phosphating hydraulic precision seamless steel pipes, pickling and phosphating hydraulic precision seamless steel pipes for Shantou marine hydraulic systems, pickling and phosphating hydraulic precision seamless steel pipes for Jieyang Xianqiao marine hydraulic systems
, process introduction
Steel pipes are pickled, cold-rolled, and cold-drawn, and then advanced high-temperature heat treatment technology (state) is used to produce steel pipes with bright, smooth, high-precision, and high-finish surfaces. There is no oxide layer on the inner and outer walls, and high precision on the inner and outer walls. The mechanical properties are suitable for bending at any angle, and can withstand high pressure, cold bending without deformation, flaring, flattening, tensile and other requirements, so that the cold bending of the steel pipe will not burst or crack, and there will be no oxide layer on the inner and outer walls, etc. advantage.
Main Features
The precision steel pipes produced are precision cold-drawn seamless pipes, which are made through anaerobic tempering treatment to eliminate surface and internal stress and then undergo phosphating and anti-rust treatment. The product has high dimensional accuracy and good ductility. It is easy to process and bend into various required shapes without the pipe cross section shrinking or flattening. The pipe has high surface precision and moderate surface hardness after anaerobic tempering treatment. It is easy to connect with ferrules. The inner hole and After the surface is phosphated and rust-proofed, it 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 relief annealed).
, main materials
The main materials used are,),, etc. 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 phosphated precision hydraulic seamless steel pipe, Shenzhen Shekou ship hydraulic system special pickled phosphated hydraulic precision seamless steel pipe, Shenzhen Yantian Port ship hydraulic system piping special black phosphated high-precision hydraulic seamless steel pipe
