Seamless steel pipes are widely used. General-purpose
seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, with the largest output, and are mainly used as pipelines or structural parts for conveying fluids. 2. According to different uses, it is divided into three types of supply: a. According to chemical composition and mechanical properties; b. According to mechanical properties; c. According to the hydraulic test. Steel pipes supplied according to categories a and b, if they are used to withstand liquid pressure, shall also be subjected to a hydrostatic test. 3. There are many kinds of
seamless steel pipes for special purposes, such as
seamless steel pipes for boilers,
seamless steel pipes for chemical power,
seamless steel pipes for geological use, and
seamless steel pipes for petroleum.
Seamless steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same and is economical section steel.
It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. The use of steel pipes to make ring parts can improve material utilization, simplify manufacturing processes, and save materials and processing Man-hours have been widely used to manufacture steel pipes.
Spiral welded pipes are mainly used in water engineering, the petrochemical industry, the chemical industry, the electric power industry, agricultural irrigation, and urban construction in China. For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structure: for piling pipe, for bridge; for wharf, road, building structure, etc.
