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 MoreHot-dip galvanized seamless tube is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in the…
Read MoreIn the process of smelting or hot working steel, due to certain factors (such as non-metallic inclusions, gases, and improper process selection or operation, etc.). Resulting in defects in the interior or surface of the seamless tube, which will seriously affect the quality of materials or products, and sometimes lead to scrapping of materials or products. Looseness, bubbles, shrinkage…
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 MoreBurs are ubiquitous in the metalworking process. No matter how advanced and sophisticated equipment you use, it will be born with the product. This is mainly due to the plastic deformation of the material and the generation of excessive iron filings at the edges of the processed material, especially for materials with good ductility or toughness, which are particularly…
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…
