Q235B spiral seam welded pipe is a commonly used transportation pipeline. Q23B is a material of carbon steel pipe. Among them, Q235B consists of Q + number + quality grade symbol + deoxidation method symbol. Its steel number is marked “Q”, which represents the yield point of the steel, and the following number represents the yield point value in MPa.
For example, Q235 represents carbon structural steel with a yield point of 235MPa. Q235B spiral seam welded pipes are single-sided and double-sided. The spiral seam welded pipes completed by double-sided submerged arc welding are subject to Comply with relevant regulations.
Spiral seam welded pipes can be classified into many categories according to size, and each category must have its own qualified logo and storage yard. As long as the forming angle is changed, steel pipes of various diameters can be produced from strip steel of the same width, which is easy to adjust.
Because it is formed by continuous bending, the fixed length of the spiral seam welded steel pipe is not restricted and the length can be determined at will. The spiral shape of the welds is evenly distributed on the entire circumference of the spiral tube, so the spiral tube has high dimensional accuracy, strong strength, and is easy to change the size. It is suitable for the production of small batches and multiple varieties of spiral tubes.
The weld seams of spiral steel pipes are longer than those of straight seam pipes of the same specifications. With the same wall thickness, spiral steel pipes bear greater pressure.
