Spiral Steel Pipes for Sales from leading Spiral Steel

Spiral Steel Pipes, made by low carbon steel, are also called spiral welded steel tube or spiral welded pipe. According to its technology and craft, the spiral welded pipe is made by Low carbon steel or Low alloy structural steel in terms of specific angle of spiral line to roll into tube blank, then formed the pipe with specific thickness and length after welded the seam of low carbon steel pipe. Spiral pipe welding joint, Sunny Steel Enterprise Ltd.Spiral pipe welding joint. Double-sided submerged arc spiral steel pipe is that arc method is welding under flux layer, and formed is that the heat generated by the burning of the arc between the wire and flux in the flux layer and melting of the wire solder and base metal. Spirally welded steel pipesThe welding process The Welding Process The welding of the spirally welded pipes is based on the Double-Sided Submerged Arc Welding (DSAW) process. The principle Arc welding works by using electric current to produce an electric arc in a gas environment. The arc's heat brings the metal to What are the Disadvantages of the Spiral Steel Pipe Sep 05, 2019 · The causes and prevention methods of the stomata of the spiral steel pipe welds, the shortcomings of the spiral steel pipe weld zone are stomata, hot cracks, and undercuts. Spiral steel pipe weld porosity not only affects the fineness of the pipe weld, but also constitutes the leakage of the pipe, and will become the induction point of corrosion, severely reducing the weld strength and durability. Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · The most common welding technique used for oil and gas pipes is the so-called high-frequency induction technology (ERW-HFI), consisting in the application of an induction current on the outer surface of the pipe able to generate a robust seam Welding technology of 9Ni Steel - China piping solution
