Product Description

Product Description

ASTM A269 LSAW ERW SSAW Sch80 Round Square Square Rectangular Welded Pipe Thin Wall Thick Wall Alloy Large Diameter Welded Steel Tube API PipeZhengde Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after being rolled and formed. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of welds. Classified by production method: arc welded pipe, resistance welded pipe, (high-frequency, low-frequency) gas welded pipe, furnace welded pipe. The production process of straight seam welded pipe is simple, with high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce larger diameter welded pipes, and billets of the same width can also be used to produce welded pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower. Thick wall coil products include: large coil, large diameter thick wall coil, various materials thick wall coil, hot rolled thick wall coil, cold rolled thick wall coil, etc.
All welded pipes can be made into galvanized welded pipes, which can be found through product consultation on the homepage.

Longitudinally welded pipe
The production process of straight seam welded pipe is simple, with high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce larger diameter welded pipes, and billets of the same width can also be used to produce welded pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower. Therefore, smaller diameter welded pipes mostly use straight seam welding, while larger diameter welded pipes mostly use spiral welding.Straight seam welded pipes are divided into longitudinal submerged arc welding (LSAW) and electric resistance welding (ERW).
Square tube
Square tube is a term for square and rectangular pipes, which refers to steel pipes with equal sides. It is made of rolled steel strip after process treatment. Generally, the strip steel is unpacked, flattened, curled, and welded to form a circular tube, which is then rolled into a square tube and cut to the required length. Also known as square and rectangular cold formed hollow steel, abbreviated as square tube and rectangular tube, with codes F and J respectively. The allowable deviation of the wall thickness of rectangular pipes shall not exceed 10% of the nominal wall thickness when the wall thickness is not greater than 10mm, and shall not exceed 8% of the wall thickness when the wall thickness is greater than 10mm, except for the wall thickness of corner and weld areas. The typical delivery length of square tube is 4000mm-12000mm, with the majority being 6000mm and 12000mm.

SSAW spiral welded pipe
Spiral welded steel pipes refer to steel pipes with joints on the surface that are formed by bending and deforming steel strips or steel plates into circular or square shapes and then welding them. According to different welding methods, it can be divided into arc welded pipes, high-frequency or low-frequency resistance welded pipes, gas welded pipes, furnace welded pipes, Bondi pipes, etc. According to the shape of the weld seam, it can be divided into straight seam welded pipes and spiral welded pipes. Welded steel pipes are used in petroleum drilling and mechanical manufacturing industries. Furnace welded pipes can be used as water and gas pipes, and large-diameter straight seam welded pipes can be used for high-pressure oil and gas transportation, etc; Spiral welded pipes are used for oil and gas transportation, pipe piles, bridge piers, etc. Welded steel pipes have lower costs and higher production efficiency than seamless steel pipes.
Thick walled coiled pipe
Thick walled coiled pipes, as the name suggests, are rolled out of steel plates. T-shaped welded pipes are the main type of coiled pipes, while spiral pipes and straight seam pipes are not strictly speaking coiled pipes. Before rolling pipes, it is necessary to familiarize oneself with technical requirements such as drawings, process material performance, etc., select an appropriate rolling machine, and determine whether to roll cold, warm, or hot. The specification and model range of hot-rolled thick walled steel pipes: diameter 400 to 3000mm, wall thickness 4 to 300mm, and length produced according to user needs. Products include: large coil tubes, large diameter thick wall coils, thick wall coils of various materials, hot rolled thick wall coils, cold rolled thick wall coils, etc.
