XAXY is a leading manufacturer of corrosion-resistant bimetallic composite pipes in China.
Main products of the company:
Lined (mechanical) bimetallic composite pipe
The lined (mechanical) bimetallic composite pipe is a high-tech product manufactured by XAXY using self-developed digital underwater detonation technology and static water pressure integrated pipe holding composite technology
This product uses carbon steel pipes as the matrix material, fully leveraging the excellent mechanical properties and affordable features of carbon steel pipes, that is, ensuring the overall strength and various mechanical indicators of the pipeline through the carbon steel matrix.
Using corrosion-resistant alloy materials as the inner lining anti-corrosion layer, fully utilizing the excellent corrosion resistance performance of corrosion-resistant alloys, that is, ensuring the corrosion resistance performance of pipelines through the corrosion-resistant alloy inner lining, thus achieving a scientific combination of reliability and economy of bimetallic composite pipes.
Inner clad (metallurgical) bimetallic composite pipe
Inner clad (metallurgical) bimetallic composite pipe is a high bonding strength bimetallic composite pipe that achieves atomic metallurgical bonding at the interface between the inner and outer pipes.
The product selects carbon steel pipes or alloy steel pipes and wall thickness based on the operating pressure of the pipeline, and they bear the pressure of the medium transported by the pipeline.
Choose corrosion-resistant alloys according to different corrosion environments, with lining pipes resistant to corrosion, and lining pipes with a wall thickness range of 1-3mm.
The manufacturing process of metallurgical composite pipes includes two methods: medium frequency induction brazing method and hot rolled formed metallurgical composite steel plate JCOE method. The product has high bonding strength and high temperature resistance, making it a scientific choice for medium transportation in many fields such as offshore and onshore oil and gas development, chemical industry…
