Structural seamless pipes are seamless steel pipes used for general structures and mechanical structures.
Seamless steel pipes for fluid transportation are general seamless steel pipes used to transport fluids such as water, oil, and gas.
Seamless steel pipes for low and medium pressure boilers are high-quality carbon structural steel hot-rolled and cold-drawn for manufacturing various structures of superheated steam pipes and boiling water pipes for low and medium-pressure boilers and superheated steam pipes and arch brick pipes for locomotive boilers. (rolled) seamless steel pipe.
Seamless steel pipes for high-pressure boilers are high-quality carbon steel alloy steel and stainless heat-resistant steel seamless steel pipes used for the heating surfaces of water tube boilers with high pressures and above.
High-pressure seamless steel pipes for fertilizer equipment are high-quality carbon structural steel and alloy steel seamless steel pipes suitable for chemical equipment and pipelines with working temperatures of ℃ and working pressures of .
Seamless steel pipes for petroleum cracking are seamless steel pipes suitable for furnace tube heat exchangers and pipelines in petroleum refineries.
Steel pipes for geological drilling are steel pipes used by geological departments for core drilling. According to their uses, they can be divided into drill pipes, drill collars, core pipes, casings and sedimentation pipes.
Seamless steel pipe for diamond core drilling is a seamless steel pipe used for drill pipe and core rod casing for diamond core drilling.
Oil drilling pipe is a seamless steel pipe with internal or external thickening at both ends used for oil drilling. There are two types of steel pipes: wired and unthreaded. Threaded pipes are connected with joints, while non-threaded pipes are connected with tool joints by butt welding.
Carbon steel seamless steel pipes for ships are carbon steel seamless steel pipes used in the manufacture of ship-grade pressure-resistant piping systems, Class II pressure-resistant piping system boilers and superheaters. The working temperature of the carbon steel seamless steel pipe wall does not exceed ℃, and the working temperature of the alloy steel seamless steel pipe wall exceeds ℃.
Seamless steel pipes for automobile axle casings are high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipes used for manufacturing automobile axle casings and drive axle housing axle tubes.
Diesel engine high-pressure oil pipe is a cold-drawn seamless steel pipe used to manufacture high-pressure pipes for diesel engine injection systems.
Precision inner diameter seamless steel pipes for hydraulic and pneumatic cylinders are cold-drawn or cold-rolled precision seamless steel pipes with precise inner diameters for manufacturing hydraulic and pneumatic cylinders.
Cold-drawn or cold-rolled precision seamless steel pipes are cold-drawn or cold-rolled precision seamless steel pipes with high dimensional accuracy and good surface finish used in mechanical structural hydraulic equipment. The use of precision seamless steel pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and at the same time help improve product quality.
Stainless steel seamless steel pipes for structural purposes are hot-rolled (extruded) and cold-drawn (rolled) stainless steel made of corrosion-resistant pipes and structural parts and parts that are widely used in chemical, petroleum, textile, medical, food machinery and other industries. Sewing steel pipe.
Stainless steel seamless steel pipes for fluid transportation are hot-rolled (extruded) and cold-drawn (rolled) seamless steel pipes made of stainless steel used to transport fluids.
Special-shaped seamless steel pipe is a general term for seamless steel pipes with other cross-sectional shapes except round pipes. According to the different cross-sectional shape and size of the steel pipe, it can be divided into special-shaped seamless steel pipes with equal wall thickness (code-named), special-shaped seamless steel pipes with unequal wall thickness (code-named) and variable-diameter special-shaped seamless steel pipes (code-named). Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have a larger moment of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
Seamless steel pipes for warm pipes are suitable for seamless steel pipes for ℃ and C grade low-temperature pressure vessel pipes and low-temperature heat exchanger pipes
