Boiler tube is a type of seamless tube. The manufacturing method is the same as that of seamless pipes, but there are strict requirements on the steel grades used to manufacture steel pipes. According to the temperature of use, it is divided into two types: general boiler tubes and high-pressure boiler tubes. The mechanical properties of boiler tubes are…
Read MoreCarbon steel tubes are made of steel castings or solid round steel through holes to make capillaries, and then made by hot rolling, cold rolling or cold drawing. Carbon steel tubes have an important position in China’s seamless steel tube industry. The key materials are mainly q235, 20#, 35#, 45#, and 16mn. The most important product implementation standards include…
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 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 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…
Read MoreSpiral pipe (SSAW) is also called spiral steel pipe or spiral welded pipe. It is made by rolling a low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain helical angle (called a forming angle), and then welding the tube seams. It can produce large diameter pipes from narrower strips. Spiral pipes are mainly…
Read MoreLow carbon steel is a type of carbon steel. Carbon is present in all steels, and as long as carbon is the predominant alloying element in this steel, the alloy is considered carbon steel. “Low carbon” steel is another name for low carbon steel, and there are other carbon steels with different carbon contents. Which one is better depends…
