We provide Nickel Alloy Tubes and Pipes in Seamless and Welded. Depends on flexible production arrangements, We offer extremely low MOQ (such as a batch of only 50 kilograms that can be arranged for production) and shorter delivery times (20 to 30 days for shipping)
1. Main production processes (main inspection processes) of hot-rolled seamless steel pipes: Pipe blank preparation and inspection → pipe blank heating → piercing → pipe rolling → reheating of raw pipe → sizing (reducing) → heat treatment → straightening of finished pipe → finishing → inspection (non-destructive, physical and chemical, bench inspection) → warehousing. 2. Production processes of cold rolled (drawn) seamless steel pipes: Blank preparation → pickling and lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection
Production Processes of Welded Pipe
welded pipe can be divided into spiral submerged arc welded pipe, straight seam double-sided submerged arc welded pipe and resistance welded pipe. The production process of spiral steel pipe: The raw materials of spiral steel pipe are strip steel coil, welding wire and flux. Before forming, the strip steel is leveled, trimmed, planed, cleaned, transported and pre-bent. The weld gap control device is used to ensure that the weld gap meets the welding requirements, and the pipe diameter, misalignment and weld gap are strictly controlled. After cutting a single steel pipe, the first three of each batch of steel pipes shall be subject to a strict first inspection system……, Enter to the welded pipe page for details.
