The seamless pipe means a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with ordinary seamless pipes, stainless steel seamless pipes have higher corrosion resistance, and the finish is better than ordinary seamless steel pipes. But this does not mean…
Read More1. Grinding of thick-walled seamless nozzle: After cutting, use an angle grinder to grind the plastic layer of the nozzle. Its purpose is to prevent the plastic layer from melting or even burning during the flange welding process, damaging the pipe, and grinding the nozzle plastic layer with an angle grinder. 2. Thick-walled seamless pipe plastic coating treatment:After polishing,…
Read MoreA flange is a disc-shaped part that is most common in plumbing engineering.It is the part that connects the pipes to the pipes. Connect to the pipe end. There are holes on the flanges for bolts to connect the two flanges tightly. The flanges are sealed with gaskets. The main factors affecting flange sealing are: bolt preload, sealing surface…
Read MoreMost of the structural seamless steel pipes work under relatively large dynamic loads. They are subjected to tension, compression, bending, torsion or shearing. Some surfaces also have friction, requiring certain wear resistance and so on. In summary, parts operate under various compound stresses. Structural seamless steel pipes are mainly structural parts of various machines and mechanisms, such as shafts,…
Read MoreConnection method of large diameter spiral steel pipe (SSAW): The common connection method of large-diameter spiral steel pipe is welding, but in some projects, threaded connection, flange connection, socket connection, groove connection and other forms are often used. 1. Welding, flange connection Welding and flange connection are traditional spiral steel pipe connection methods, which are far from meeting the…
