Composite pipe is a kind of engineering pipeline that develops rapidly nearly ten years abroad, it has wide varieties and functions. At present, domestic and overseas bimetal composite pipe is mostly formed by the mechanical method (explosion forming, tube hydro forming, drawing, rolling, etc. ), both inside and outside layer metal is simple mechanical bonding, the combining boundary exists macroscopic clearance, so it is hard to meet the high-end user’s requirements.
Metallurgical bonding bimetal composite pipe of Shanghai Metal Corporation is the combination of primary industry material and high technology of metallurgical process, through the typical hot extrusion or hot extrusion and cold forming process, metallurgical bonding interface of multiple material and base material can be achieved, so as to obtain high quality composite pipe. At the same time, as the pipe forming technology is extrusion process and the extrusion process is a three compressive stress state, so the performance difference of pipe in vertical and horizontal is small and the quality is superior. It is widely used in high temperature and high pressure, strong corrosion, high wear and tear and other harsh working environment such as petroleum, chemical, refinery, gas, boiler, power plant, mining machinery, ship, vehicles and so on.
Manufacturing of Bi-metal Composite Seamless Tube & Pipe:
1. Fatigue test-transection
2. Fatigue test-tubulation
Through the steel cutting, it can be seen that two layer metal still remain solid concrete without any separation and cracking phenomenon, just like the processing of single metal, while the mechanical composite steel pipe can’t be like this.
Packaging of Bi-metal Composite Seamless Tube & Pipe
Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.
