You know seamless is raw material for many fields. Our precision seamless tube is used for gas spring products, auto and motorcycle such as bushing and shock absorber, and hydraulic oil. So we also need know the factor for how to impact the precision of seamless steel tube. The cross section of the

Steel pipe production plays an important role in the national economy, and all countries in the world attach great importance to the development of steel pipe production technology. At present, the annual output of steel pipes in the world has exceeded 700,000 tons. In the consumption of steel mater

The working steel pipe, the glass wool thermal insulation layer, the aluminum foil reflective layer, the stainless steel fastening tape, the sliding guide bracket, the air insulation layer, the outer protective steel pipe and the outer anti-corrosion layer of the conveying medium are sequentially co

In actual production, heat treatment deformation will bring difficulties to subsequent processing, affecting production efficiency, resulting in scrapping due to excessive deformation and increasing costs. Deformation is a problem that is difficult to solve by heat treatment. It is impossible to com

Many seamless steel tube manufacturers require special materials for their parts, ordinary materials can not meet the performance standards, and specifications sometimes are not national standards. This is a headache for purchasers of parts manufacturers. Because the special material seamless steel

The three-layer polyethylene (3PE) anticorrosive coating has been widely used in the petroleum pipeline industry due to its good corrosion resistance, water vapor permeability and mechanical properties. The end of the steel pipe of the anticorrosive layer is prone to the problem of warping caused by

Alloy steel pipes are mainly used in power plants, nuclear power plants, high-pressure boilers, high-temperature superheaters and reheaters and other high-pressure and high-temperature pipelines and equipment. They are made of high-quality carbon steel, alloy structural steel and stainless heat-resi
