ASTM API LSAW Steel Pipe Welded Steel Tube
Description
Double sided submerged arc straight seam welding of steel pipes is an efficient steel pipe welding process with good welding quality and high productivity. Here is its detailed introduction:
Process principle:
Prefabrication preparation: Firstly, the steel plate is cut into the required length and pre bent and formed according to the requirements.
Docking: The cut steel plate is docked at a certain angle through docking equipment to form a straight seam.
Welding: During the welding process, the welding equipment will weld both the inner and outer sides of the steel pipe simultaneously, using submerged arc welding.
Weld seam control: During the welding process, welding parameters such as current, voltage, and welding speed need to be strictly controlled to ensure the quality and consistency of the weld seam.
Slag removal and shaping: After welding is completed, it is necessary to perform slag removal and shaping treatment on the weld seam to ensure the smoothness and quality of the weld surface.
Equipment and materials:
Welding equipment: submerged arc welding machine, welding power supply, welding gun, etc.
Welding materials: welding wire, flux, etc.
Auxiliary equipment: docking equipment, cutting equipment, slag removal equipment, etc.
Advantages:
High efficiency: The double-sided submerged arc welding process can achieve continuous automated production and improve production efficiency.
High quality: Due to the simultaneous welding on both inner and outer sides during the welding process, and the use of submerged arc welding technology, the weld quality is good, with good penetration and strength.
Widely applicable: can be used to produce steel pipes of different specifications and materials, suitable for various engineering and application fields.
Application field:
Pipeline engineering: a pipeline used to transport fluids such as oil, natural gas, and water.
Structural engineering: used for steel structural supports in structural engineering such as bridges and buildings.
Manufacturing industry: used to manufacture various mechanical equipment, automotive components, etc.
Double sided submerged arc straight seam welded steel pipes have the characteristics of high efficiency and quality, and are therefore widely used in engineering construction and manufacturing.
