Description

Steel-high chromium bimetal wear-resisting compound Y pipe exterior wall uses the ordinary seamless steel tube, through the centrifugal forming process forms the high chromium cast steel lining compound. The outer wall of the Y pipe is heated and the inner layer is made of high chromium cast steel, which has the wear-resisting property of high alloy cast steel, and can withstand pressure and has higher mechanical properties.

Special Corundum ceramics made of rare metal oxides as solvents and sintered at high temperature by 1730 ℃ through bonding, welding, mosaic, riveting and socket technology, a variety of wear-resistant ceramic pieces, block brick materials in the pipe wear surface, so as to form a surface with excellent wear resistance, and the matrix is still using the composite pipe of ordinary metal.

Do you know what’s the cladding steel pipe used for?

It not only satisfies the special requirements, but also saves costs.
In a clad line pipe, the corrosion-resistant alloy forms a complete barrier layer on the internal surface of carbon or low-alloy steel pipe (usually referred to as the “backing steel”). In general, use of clad or bi-metal-lined pipe allows the economic use of expensive CRA materials,It has been widely concerned and used in many other fields abroad.

Features of High chromium cast iron pipes

The wear resistance of the high-chromium bimetallic lined pipe is at least many times that of ordinary steel pipes. The bimetallic composite steel pipe has inner and outer double layers of metal, the inner lining is made of wear-resistant cast iron, the inner lining material has good wear resistance and corrosion resistance, and the outer layer material has high mechanical strength and high impact resistance. The lost foam composite process is directly adopted, and the metallurgical composite is formed by casting, which is safe and reliable to use.

Lined high-chromium bimetallic composite pipes include high-chromium bimetallic composite straight pipes lined, high-chromium bimetallic composite elbows lined, high-chromium bimetallic composite tee lined, Lined with high-chromium bimetal composite multi-pass, lined with high-chromium bi-metal composite reducer, lined with high-chromium bi-metal composite flash buffer device, etc.

Chrome-Moly

  • Chromium-Molybdenum Alloy Steel or Chrome-Moly, CrMo is an alloy steel intended for high temperature and high pressure services.
  • Chrome-Moly is used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength.
  • Chrome-Moly has a better strength to Weight ratio than steel, which enables designers to use thinner wall pipe or smaller diameter tubing to reduce overall weight.
  • Chromium-Molybdenum Alloy Steel has strong resistance to rupturing at high temperatures and high pressures.
  • Chrome-Moly is also resistant to cracking from hydrogen attack and hot sulfide corrosion cracking.
  • Chrome-Moly grades P-11, P-22, P-91 and P-92 are used in the power industry.
  • Chrome-Moly grades P-5 and P-9 are used in petro-chemical refinery processes.
  • Chrome-Moly Forged Fittings & Flanges are available in grades F-5, F-9, F-11, F-22, F-91, F92.
  • Chrome-Moly Alloy Butt Weld Fittings are available in grades WP-5, WP-9, WP-11, WP-22, SP-91, WP-92.
  • F11 and F22 meet NACE-MRO 175.

Bimetal wear resistant products including: double metal wear-resisting straight pipe and double metal wear-resisting bend, double metal wear tee, double metal wear resistance reducer adopts the pipe fittings such as vacuum suction casting composite process, its advanced technology, effectively solve the problem of the bent pipe cannot be composite, bending and other various special-shaped pipe can do the whole compound, don’t change the material flow in the pipe bending trajectory, reduce resistance material conveying.

The outer wall of the centrifugal pipe is made of carbon steel, which ensures that the bimetal wear-resistant pipe has high mechanical strength and impact resistance.The inner lining wear resistance layer adopts the anti-wear alloy steel series independently developed by our company. The steel mainly adds alloy such as cr-ni-mo-cu-re and so on. Through the tempering heat treatment process, the alloy steel has strong wear resistance and corrosion resistance, high mechanical strength and impact resistance.
The whole set of process of our factory is the first in China, which fills the blank of anti-corrosion and wear-resistant industrial pipeline in China and has reached the international advanced level. It has been widely used in mining, metallurgy, coal, electric power and other industries, and is an ideal wear-resistant pipeline.
