Stainless steel pipes are widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils.

Galvanized steel pipe is a welded steel pipe with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc.

Ductile iron pipe refers to the pipe made by high-speed centrifugal casting of centrifugal ductile iron machine after casting molten iron above No. 18 with the addition of nodularizer, referred to as ball pipe, ductile iron pipe and ductile cast pipe. Mainly used for the transportation of tap water, it is an ideal material for tap water pipelines.

Special-shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the shape and size of the cross-section of the steel pipe, it can be divided into special-shaped seamless steel pipes with equal wall thickness (code-named D), special-shaped seamless steel pipes with different wall thickness (code-named BD), and special-shaped seamless steel pipes with variable diameter (code-named BJ).

Thin-walled stainless steel pipes with a wall thickness of only 0.6-1.2 mm are featured in high-quality drinking water systems, hot water systems, and water supply systems that put safety and hygiene first. They are safe, reliable, hygienic, environmentally friendly, and economical and applicable. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environment-friendly pipes with the best comprehensive performance in the water supply system. comparable effect.

Cold-drawn or cold-rolled precision seamless steel pipes for hydraulic equipment with high dimensional accuracy and good surface finish. Precision seamless steel pipe is used to manufacture mechanical structures or hydraulic equipment, etc., and the precision steel pipe is a high-precision seamless steel pipe processed by cold drawing or cold rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipes, no leakage under high pressure, high precision, high smoothness, no deformation in cold bending, flaring, and no cracks in flattening, it is mainly used to produce pneumatic or hydraulic products.

National standard spiral steel pipe referred to as 9711.1 spiral steel pipe, 9711.2 spiral steel pipe, material classification: 16Mn material spiral steel pipe, Q345B spiral steel pipe, L245 spiral steel pipe, L360 spiral steel pipe, X40-X80 spiral steel pipe, main purpose, spiral steel pipe for sewage treatment, water purification Spiral steel pipes, spiral steel pipes for water plants, spiral steel pipes for power plant chemical enterprises, spiral steel pipes for nuclear power, spiral steel pipes for conveying flammable fluids, spiral steel pipes for conveying non-combustible fluids, national standard spiral steel pipes, Ministry of Petroleum standard SY/T5037 spiral steel pipes Steel Pipe. The product is made of hot-rolled steel strip, spirally formed at constant temperature, and welded by automatic submerged arc welding process. The product implements API SPEC 5L, EN10217, GB/T9711.1, GB/T9711.2 standards. It is mainly used for transporting flammable and non-combustible fluids and steel structures in oil and gas industries.
