Carbon steel flanges, that is, flanges or end flange connectors whose body material is carbon steel. Flanges containing carbon steel are called carbon steel flanges. Common materials are cast carbon steel grade WCB, forging A105, or Q235B, A3, 10#, #20 steel, 16 manganese, 45 steel, Q345B, etc.

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.

Oil casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well uses several layers of casing according to different drilling depths and geological conditions. Cement cementing is used after the casing is lowered into the well. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes.
Casing can be divided into: conduit, surface casing, technical casing and oil layer casing according to the usage.

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.

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.
