Common steel pipes mainly include welded pipes and seamless pipes (SMLS). In the process of engineering construction, appropriate steel pipes will be selected in combination with specific construction conditions, and cost will be the primary factor. Therefore, this paper distinguishes welded steel pipes and seamless steel pipes from the aspects of steel pipe performance, technology and identification methods, hoping…
Read MoreSeamless pipe (SMLS) is a steel pipe made of a single piece of metal with no joints on the surface. It is made of a steel ingot or a solid tube blank through perforation to form a capillary tube, and then hot-rolled, cold-rolled or cold-drawn. The characteristics of seamless steel pipes are different from other steel pipes. They are…
Read MoreSpiral steel pipes and seamless steel pipes are relatively common pipes in life, and they are used in house decoration and construction. So what is the difference between spiral steel pipes and seamless steel pipes? What is a spiral steel pipe? Spiral steel pipe (SSAW) is a spiral seam steel pipe made of strip steel coil as raw material,…
Read MoreThe uneven wall thickness of the seamless tube(SMLS) is mainly manifested in the phenomenon of uneven wall thickness of the spiral shape, uneven wall thickness of the straight line, and thicker and thinner walls at the head and tail. The influence of continuous rolling process adjustment of seamless tubes is an important factor leading to uneven wall thickness of…

The customer said that during the construction process, after evaluation by technicians, several specifications of boiler…
Read MoreThe galvanizing method of seamless pipe (SMLS) shall be hot-dip galvanizing. Size, shape, surface, mechanical properties and process performance inspection should be carried out before galvanizing. Surface quality requirements of galvanized layer: The galvanized layer on the inner and outer surfaces of the seamless steel pipe should be complete, no black spots and air bubbles without zinc plating are…
