How To Identify Seamless Pipes And Welded Pipes

Jan 13, 2024 Leave a message

Seamless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, gas, water, and certain solid materials.

Compared with solid steel materials such as round steel, steel pipes are lighter in weight when their bending and torsional strength is the same. They are an economical section of steel and are widely used in the manufacturing of structural and mechanical parts, such as oil drill rods, automotive transmission shafts, bicycle frames, and steel scaffolding used in construction.

Using steel pipes to manufacture circular parts can improve material utilization, simplify manufacturing processes, save materials and processing time, and have been widely used in the manufacturing of steel pipes. The molding process is different. Like a water pipe line, it is usually welded with steel plates, and after welding, a weld seam can be found on it; The diameter is usually a spiral weld seam.

Seamless steel pipes are generally formed through processing techniques such as the molten state of the steel after circumferential welding, so they are not welded. In terms of performance, especially in terms of significantly improving the bearing capacity of bearings compared to ordinary steel pipes, it is often used in high-pressure equipment. Such as hydraulic equipment pipeline connections.

The welding part of ordinary steel pipes is a weak link, and welding quality is the main factor affecting the overall performance. People who have lived in the north have experience with water or heating pipes in winter, and the places where explosions usually occur are welded steel pipes and non seamless steel pipes.
