Large diameter thick wall welded steel pipe

It is a product with an outer diameter greater than 540mm and a thickness-to-diameter ratio greater than or equal to 3%. It has the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, etc. The product is mainly used in petroleum refining, hydrocracking equipment, high temperature synthesis equipment and other fields.

Large diameter thin wall welded pipe

It is a product with an outer diameter greater than 540mm and a thickness to outer diameter ratio less than 3%. It has the characteristics of corrosion resistance, energy saving and environmental protection, and long service life. It is mainly used in ventilation, water supply, gas drainage, food, medicine and other industries.

Small diameter welded pipe

Welded steel pipes with an outer diameter less than 540mm are mainly divided into:

Lined pipe: It has the characteristics of corrosion resistance, high temperature resistance, low temperature resistance, etc., and is mainly used in harsh environments such as long-distance oil transportation, liquefied natural gas, and seabed;

Boiler heat exchanger straight tube: It is an equipment component widely used in the industrial field. It is mainly used to transfer heat energy in the boiler system.

Fluid Pipes: Stainless steel fluid pipes are designed to withstand high pressures and extreme temperatures while maintaining their structural integrity and functionality. Stainless steel fluid piping is an integral component in food processing, chemical, pharmaceutical, water treatment and many other industries.

Special-shaped tube

It is a stainless steel pipe with a special shape. It is different from the conventional round shape and is a highly customized product.

Square and rectangular pipe: It is a name for square pipe and rectangular pipe. The strip steel is unpacked, flattened, curled, welded and other processes to form round tubes, which are then rolled into square tubes. It can be used in decoration, machine tool equipment, machinery industry, chemical industry, steel structure, shipbuilding, automobile, and other fields.

U-shaped pipe: This type of pipe is named after its unique U-shaped structural design. It is a common industrial pipe fitting. It is mainly made of high-quality stainless steel and has good corrosion resistance and high temperature resistance. It is usually used in fluid transmission systems, such as chemical, food processing, pharmaceutical, water treatment and other industries.

Coil

Stainless steel coil designs are often very flexible and can be customized in different sizes and shapes to suit specific application needs. Their smooth surface facilitates the smooth passage of fluids, reducing friction and pressure loss, thereby increasing the overall efficiency of the system. The main features of the product are uniform wall thickness, high corrosion resistance, good heat exchange and heat transfer effects, and only one longitudinal seam. The longest length can reach 900 meters. It is mainly used in heat exchangers, evaporators, distillation, and air conditioning. Scenarios such as analysis, heat tracing, medicine and biology.

nuclear waste storage facility

Also known as storage well, it is a stainless steel structural part. The storage well consists of three parts. The components are assembled and welded by stainless steel pipes, stainless steel flanges and several carbon steel parts, among which the shielding plug needs to be filled with concrete. The component production process involves 6 sets of assembly spot welding fixtures, 3 sets of product verification test fixtures, and several welding fixtures. The final product must meet the GB/T 1804-2000 standard. This product has the advantages of high strength, high corrosion resistance, good toughness, vibration impact resistance and excellent seismic resistance. It is widely used in nuclear power plants, medical facilities, research laboratories, ore refining and other scenarios.

Composite pipe

Bimetal composite pipe is a steel pipe that combines a carbon steel base layer and a corrosion-resistant layer through a composite method of inner coating (metallurgical bonding) or lining (mechanical bonding). The corrosion-resistant layer can be austenitic stainless steel, copper-based alloy, nickel-based Alloy, Hastelloy, titanium, titanium alloy, duplex stainless steel, etc. Bimetallic composite pipes not only have the high corrosion resistance of corrosion-resistant alloys, but also have the good bending strength and impact resistance of carbon steel, and at the same time meet the performance requirements Under the premise of meeting the requirements, scarce metal resources such as Cr, Ni, and Ti are saved.
