Main Material:
Base: Carbon Steel, Alloy Steel, Pipeline Steel, etc. Lining: Stainless Steel, Duplex steel, Nickel-based Alloy, Titanium, Copper and other Corrosion - resistant Alloys.
Application Condition:
Widely used in Petrochemical, Coal Chemical, Refining, Oil and Gas Transmission, Marine Environment, Power, Heating and Other projects
Product Characteristics:
Adopts the patent technology make the material of two kinds of interference, ensure the working condition of medium in corrosion environment, meet the requirement of pressure, and greatly reduces the cost of materials, at the same time have a big binding
Our Company offers a variety of CRA clad or lined steel pipes including longitudinal seam clad steel pipe, helical seam clad steel pipe and seamless or welded lined steel pipe, and produces the corresponding elbows etc. in accordance with API Spec 5LD, DNV-OS-F101, SY/T6623 and CJ/T192. The products can be widely used in high corrosion environment, such as oilfield exploitation, oil and gas gathering and transportation, oil and gas transportation, corrosive medium transportation, petrochemical industry, pressure vessels, food industry, chemical fertilizer, pharmacy, sewage treatment, seawater desalination and drinking water etc., and are of high performance to price ratio.
CRA clad steel pipe:
Use hot rolling metallurgy composite plate or coil as material, modern advanced pipe-making technology (UOE, JCOE, COE and SAWH) to forming, SAWL or SAWH, and TIG etc. combined automatic welding process to complete welding. The welding quality is stable, and the product size accuracy is high. The composite plate or coil is manufactured by hot rolling technology, which can achieve metallurgical bonding of the atom between corrosion-resistant clad and the backing layer, the binding force reaches above 200MPa, the binding area rate can reach above 99.9%, and the performance is stable and reliable. The clad can meet the corrosion-resistant specific performance requirements, and the backing layer can meet the strength and rigidity condition the structure required.
Seamless or welded Lined steel pipe:
Seamless or welded carbon steel pipe as the outer backing layer, and corrosion-resistant alloy pipe as the inner corrosion layer, using the limit elasticity hydraulic composite method innovated independently by the company achieves the composite between the inner and outer pipe and forms the mechanical liner pipe. Through the composite technology, the optimal composite effect of mechanical liner can be achieved, and the shear stress between inside and outside metal layer can reach 2.0MPa (the relative standard requires 0.2-0.5MPa). Meanwhile, we develops specially the pipe ends automatic overlaying technology and NC machine tools specialized for beveling, which can process complex shape bevels such as U-bevel, and guarantees the conformity of pipe mouth diameter and bevel size, so as to operate pipe jointing on site.
