Stainless steel welded pipe (abbreviated as welded pipe) is made by bending and forming steel plates or strips, then welding the seams. Our company has JCO large-diameter single-piece forming production lines and FFX continuous forming automatic welding production lines. We have a complete range of product specifications and steel types, capable of producing various stainless steel and special alloy welded pipes with diameters ranging from φ8mm to φ3600mm and wall thicknesses from 0.2mm to 120mm. The materials cover austenitic and super austenitic stainless steels, duplex and super duplex steels, copper alloys, titanium alloys, nickel-based alloys, Hastelloy, bimetallic composite materials, etc., with an annual production capacity of 150,000 tons.
Products with an outer diameter greater than 540mm and a thickness-to-outer diameter ratio of at least 3% possess high-temperature resistance, high-pressure resistance, and corrosion resistance. Primarily used in petroleum refining, hydrogen cracking units, and high-temperature synthesis devices.
Products with an outer diameter greater than 540mm and a thickness-to-outer-diameter ratio of less than 3% possess characteristics such as corrosion resistance, energy conservation, environmental protection, and long service life. Mainly used in industries such as ventilation, water supply, gas extraction, food, and pharmaceuticals.
Welded steel pipes with an outer diameter of less than 540mm are mainly divided into:
Lined pipes: They have characteristics such as corrosion resistance, high temperature resistance, and low temperature resistance. They are mainly used in harsh environments such as long-distance oil transportation, liquefied natural gas, and undersea.
Boiler heat exchanger straight pipe: It is a widely used equipment component in the industrial field. It is mainly used for heat transfer in boiler systems.
Fluid pipelines: The design of stainless steel fluid pipelines allows them to withstand high pressure and extreme temperatures while maintaining their structural integrity and functionality. In food processing, chemical industry, pharmaceuticals, water treatment, and many other industries, stainless steel fluid pipelines are an indispensable component.
Irregular pipe is a type of stainless steel pipe with a special shape, different from the regular round shape, and is a highly customized product.
Square and rectangular pipes: This term refers to square and rectangular-shaped pipes. Strip steel undergoes processes such as unpacking, leveling, curling, welding, etc., to form a round pipe, which is then rolled into a square pipe. They can be used in decoration, machine tool equipment, mechanical industry, chemical industry, steel structure, shipbuilding, automobiles, and other fields. U-shaped pipe: This type of pipe gets its name from its unique U-shaped structural design. It is a common industrial pipeline fitting, mainly made of high-quality stainless steel materials, with excellent corrosion resistance and high-temperature resistance. It is usually used in fluid transmission systems, such as in the chemical, food processing, pharmaceutical, water treatment, and other industries.
The design of stainless steel coiled pipe is usually very flexible, allowing for customization in different sizes and shapes according to specific application needs. Their smooth surface helps fluids pass through smoothly, reducing friction and pressure loss, thereby improving the overall efficiency of the system. The main characteristics of the product include uniform wall thickness, high corrosion resistance, good heat exchange and heat transfer effects, with only one longitudinal seam, and a maximum length of up to 900 meters. They are mainly used in heat exchangers, evaporators, distillation, air separation, tracing, pharmaceutical biology and other scenarios.
Nuclear waste storage devices, also known as storageNuclear waste storage devices, also known as storage steel structures consisting of three components stainless steel flanges, and several carbon steel parts, with the shielding plug requiring concrete filling. The 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 boasts high strength, excellent corrosion resistance, good toughness, and superior resistance to vibration, shock, and seismic performance. It is widely used in nuclear power plants, medical facilities, research laboratories, and ore extraction scenarios.
Bimetallic composite pipes are steel pipes that combine a carbon steel base layer with a corrosion-resistant layer through either cladding (metallurgical bonding) or lining (mechanical bonding). The corrosion-resistant layer can be made of austenitic stainless steel, copper-based alloys, nickel-based alloys, Hastelloy, titanium, titanium alloys, duplex stainless steel, etc. Bimetallic composite pipes not only possess the high corrosion resistance of corrosion-resistant alloys but also have the good bending strength and impact resistance of carbon steel. At the same time, they save scarce metal resources such as Cr, Ni, Ti, etc., while meeting performance requirements.
