          CRA Pipe

          Product Introduction 

          CRA steel pipe is based on carbon steel pipe or alloy steel pipe as a substrate, using composite technology in its inner surface lined with a certain thickness of stainless steel pipe and other corrosion-resistant alloy pipe to compound into a kind of bimetallic composite pipeline.

          Product Advantage

          Corrosion resistance, impact resistance, low thermal expansion, pressure resistance, high temperature resistance, reduce the use of pure stainless steel pipe and reduce operating costs.

          Product Characteristics 

          With uniform, smooth, safe and controllable expansion pressure, the hydrostatic expansion composite process realizes the whole process of automatic operation, monitoring and recording through the supporting system. The combination of liner compounded by hydrostatic expanding technology is uniform, can be controlled within the pressure range, to obtain the ideal composite bonding force, and the base steel pipe does not produce any bending instability deformation.

          Product Size

          (a)Carbon steel pipe grade: L245-X80 (API 5L standard);
          (b)Lined pipe: 304L, 316L, 2205, nickel-based alloy 825, nickel-based alloy 625, etc. (wall thickness 2.5mm-3mm);
          (c)Pipe diameter: φ60.3mm-φ914mm (2"-36").

          產(chǎn)品性能

          (a)Performance better than: National Energy Administration issued standard SY/T 6623;
          (b)American Petroleum Institute standard API 5LD;
          (c)DNV standard DNV-OS-F101 and other standard requirements.

           
          Application Scope 

          Oil industry, natural gas industry, water-related industry transportation pipeline.

          Manufacturing Capability 

          Take φ219mm pipe as an example, the annual production capacity of hydraulic composite can reach 700km.
