The 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…
Read MoreIn the casting and rolling process of seamless steel pipe, one of the important technical indicators to measure the processing quality of seamless steel pipe is straightness. Most seamless pipes need to be straightened, and the oblique roller straightening has high work efficiency and is in the main position. However, for the bending deformation of steel pipe ends and…
Read MoreFire-fighting pipeline refers to the pipeline material used for fire-fighting, connecting fire-fighting equipment and equipment, and transporting fire-fighting water, gas or other media. Due to special requirements, the thickness and material of fire-fighting pipes have special requirements, and red paint is sprayed to transport fire-fighting water. Since the fire pipeline is often in a static state, the requirements for…
Read MoreForming and sizing of seamless pipes, some hole design and adjustment methods will directly affect the quality, so we should pay attention to the following eight points when handling the forming of seamless pipes: 1. Before there is no perforation, the hole shape of each rack should be adjusted, and the size of each pass should be measured to…

Read MoreThe bright heat treatment of seamless tubes does not have to be a vacuum furnace. It is heated in a protective atmosphere, which is what we often call a continuous bright quenching furnace. The protective gas is pure hydrogen or a mixture of nitrogen and hydrogen, which can also decompose ammonia into gas. There is another kind, quenching in…
Read MoreCarbon steel welded pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). The carbon steel welded pipes produced by these three processes have their own positioning in the application field because of their different raw materials, forming processes, caliber size and quality. 1. Straight seam…
