Reducers are made by either seamless or welded methods. For seamless reducers, a billet is heated, extruded, and drawn into the desired shape. For welded reducers, metal sheets are formed into the reducer shape, welded, and heat-treated. Both types are then machined, tested for pressure and strength, and undergo surface treatments to ensure quality and performance.
Tees are made by either seamless or welded methods. For seamless tees, a billet is heated, pierced, and extruded into the tee shape. For welded tees, pipe sections are cut, formed into a tee shape, and welded. Both types are then heat-treated, inspected for strength and quality, and undergo surface finishing processes.
Cross are made by either seamless or welded methods. For seamless tees, a billet is heated, pierced, and extruded into the tee shape. For welded tees, pipe sections are cut, formed into a tee shape, and welded. Both types are then heat-treated, inspected for strength and quality, and undergo surface finishing processes.
Stub ends are made by cutting pipe sections to the desired length, followed by forming the end into a flange-like shape. The pipe is then beveled or machined to fit the corresponding flange. For welded stub ends, the pipe is welded to create the required dimensions. Finally, the stub end is heat-treated, tested, and surface-finished.
End caps are manufactured by cutting a pipe to the desired length, then sealing one end to form a closed cap. The material is shaped using molding or pressing techniques. Afterward, the cap is welded (if required), heat-treated, and tested for strength. Finally, it undergoes surface finishing for smoothness and corrosion resistance.
