Seamless steel pipes are widely used.
1. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, and have the largest output. They are mainly used as pipelines or structural parts for conveying fluids.
2. According to different purposes, it can be supplied in three categories:
a. Supply according to chemical composition and mechanical properties;
b. Supply according to mechanical performance;
c. According to the water pressure test supply. Steel pipes supplied according to categories a and b, if used to withstand liquid pressure, shall also be subjected to a hydraulic test.
3. Special-purpose seamless pipes include seamless pipes for boilers, chemical and electric power, seamless steel pipes for geology, and seamless pipes for petroleum.
Seamless steel pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in flexural and torsional strength and is economical cross-section steel.
It 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 building construction. Steel pipes are used to make ring parts, which can improve material utilization, simplify manufacturing procedures, and save materials and processing. Working hours, steel pipes have been widely used for manufacturing.
Spiral welded pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction in China. It used for liquid transportation: water supply and drainage. Used for gas transportation: coal gas, steam, liquefied petroleum gas. For structural purposes: as piling pipes and bridges; pipes for docks, roads, and building structures.
