Fire-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…

Read MoreSurface heat treatment is divided into two categories: one is surface quenching and tempering heat treatment, and the other is chemical heat treatment. Common hardness testing methods are as follows: 1. Surface quenching and tempering heat treatment The surface quenching and tempering heat treatment of seamless steel pipes is usually carried out by induction heating or flame heating. The…
Read MoreCold rolling refers to the processing of steel plates or strips into various types of steel through cold working such as cold drawing, cold bending, and cold drawing at room temperature. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Carbon steel pipes are made of steel ingots or solid billets through perforation into…
