Thin-walled carbon steel pipe saddle joint (carbon steel metal casing model form)

Steel pipe (Steel pipe) is used to transport fluid and powdery solids, exchange heat, manufacture mechanical parts and containers, and is also an economical steel. The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry and Drilling, production and transportation of oil and natural gas have strongly promoted the development of steel pipe industry in terms of variety, output and quality. Steel pipes can be divided into two categories according to production methods: seamless steel pipes and seamed steel pipes, and seamed steel pipes are divided into two types: straight seam steel pipes and spiral seam welded pipes. 1 Classification of steel pipes According to production methods, steel pipes can be divided into two categories according to production methods: seamless steel pipes and seamed steel pipes, and seamed steel pipes are referred to as straight steel pipes for short. 1. According to the production method, seamless steel pipes can be divided into: hot rolled seamless pipes, cold drawn pipes, precision steel pipes, thermal expansion pipes, cold spinning pipes and extruded pipes. Seamless steel pipes are made of high-quality carbon steel or alloy steel, and can be divided into hot-rolled and cold-rolled (drawn). 2. Welded steel pipes are divided into furnace welded pipes,
