Several common applications of welded pipes

Thread Content

As is well known, welded pipes are made by bending steel plates or steel strips and then welding them together. Common products include ordinary welded pipes, standard carbon steel wire sleeves, straight-seam welded pipes, and spiral-seam steel pipes. Jingbo Cloud Commerce will show you their specific applications. Generally, welded pipes are used for transporting fluids under relatively low pressures, such as water, gas, air, oil, and heating steam. Ordinary carbon steel wire sleeves (GB3640-88) are steel tubes used to protect wires in electrical installation projects such as industrial and civil buildings and the installation of machinery and equipment. Straight-seam electric welded pipe (YB242-63) is a type of steel pipe whose weld seam is parallel to the longitudinal direction of the pipe. They are generally classified into metric welded pipes, thin-walled welded pipes, transformer cooling oil pipes, and so on. Spiral-welded submerged arc welded pipes for transporting pressurized fluids (SY5036-83) are made by using hot-rolled steel strip coils as the pipe blanks, forming them in a spiral shape at room temperature, and welding them using double-sided submerged arc welding; they are used as spiral-welded steel pipes for transporting pressurized fluids. Steel pipes have strong pressure resistance and good weldability; they have undergone various rigorous scientific inspections and tests, making them safe and reliable to use. Steel pipes have a large diameter, offering high transportation efficiency and helping to reduce investment in pipeline installation. Primarily used for pipelines transporting oil and natural gas. Spiral-welded high-frequency welded pipes for transporting pressurized fluids (SY5038-83) are made by using hot-rolled steel strip coils as the pipe blanks, forming them in a spiral shape at room temperature, and welding them using a high-frequency lap welding method; they are thus spiral-welded high-frequency welded pipes designed for transporting pressurized fluids. It is mainly used for laying pipelines to transport oil, natural gas, etc. Welded pipes can be tested using three hardness testing methods: Brinell, Rockwell, and Vickers, to determine the HB, HRB (or HRC), and HV hardness values; it is sufficient to measure just one of these three values.
