SSAW steel pipe is formed by rolling and welding a steel strip in a helix or spiral direction, making the weld seam in a spiral line. The spiral welded process makes it possible to create large diameter options. Spiral submerged arc welding pipe is used in pipelines for the transportation and distribution of oil, natural gas, water and other flammable and non-flammable liquids. At the same time, it can be used in structures for construction and other general purposes due to the wide range of sizes.

For the transport of liquids: water supply, drainage. And for transporting gases: gas, steam, liquefied petroleum gas. It is also used for structural purposes: as piling pipe, for bridges, piers, roads, buildings and other pipe structures.

SSAW pipe diameter range is generally 8 inches to 140 inches (219.1mm to 3620mm). The wall thickness is 5.5mm to 24.5mm.

API 5L PSL1 Line Pipe covers seamless and welded carbon steel line pipe which suitable for use in conveying gas and oil industry. Our factory can offer a high-quality API 5L Gr.b line pipe to all of the worlds with an API certificate. API 5L gr.b ERW steel pipe is a very common steel grade, usually for psl1 gr.b pipe.

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.

EN 10219 square tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields.

The EN 10219 specification is segregated into two parts. While part 1 covers the Technical delivery conditions of the en 10219 pipe. Part 2 covers its dimensions, tolerances, as well as its sectional properties. Cold formed welded structures produced under this standard are available in shapes like square, circular, or rectangular forms.  

The hollow sectioned en 10219 square tube typically does not require subsequent heat treatment. Grade s235jr steel pipe designated with the letters JR indicate the qualities with specified impact properties at room temperature or its specified impact properties at a temperature of 0℃. Whereas the numeric value in the term EN 10219 S235JR is indicative of its minimum yield strength, which in this case stands at about 235 N/mm2.

EN 10219 rectangular tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields. The rectangle dimension range is 40×20 to 400x200mm. In length, it is available as 6 to 12/18 m.

Cold Formed EN 10219 S355J0H Rectangular Hollow Section is inspecting product on various parameters. This Rectangular Hollow Section is obtainable through means of solutions as per the drawings and designs have given by the clients. The industries like infrastructure development, petrochemicals, boiler manufacturers etc find this grade Rectangular Hollow Section pipe ideal for fulfilling application needs. Moreover, these pipes are factory made by making use of excellent quality of materials and technology of cutting edge under the supervision of experts.

EN 10210 rectangular tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields.

BS EN 10210 Pipes Material is made up of a low carbon steel material that has 0.22% carbon, silicon, 1.6% manganese, sulfur, phosphorus and other elements in trace amounts. Lai is a leading EN 10210-1 Pipes Manufacturer and supplier.

Black annealed square tube is welded from strip steel, after pickling, the process in turn is cold-rolled, divide into strips of corresponding width according to the model, annealed, air-dried for 24 hours, and rolled into shape. It is widely used in furniture, fence, roofing, interior decoration, building curtain wall, etc. Black annealed square tube reduces hardness, it is not easy to break, so it is easier to secondary processing and deformation.

EN 10210 square tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse and other fields.

ASTM A500 rectangular tube is welded from strip steel or plate after crimping, it is widely used in steel structure plant, warehouse, bridge building, intelligent greenhouse, civil construction and other fields.

Structural tubing per ASTM A500 is tubing produced and used for structural applications. Standard strength requirements of the tube help dictate applications for which certain tubing is most appropriate. Structural tube is often referred to as hollow structural sections or HSS. Structural Tubing, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions.
