The specifications and models of welded steel pipes for piles refer to the outer diameter, wall thickness, material and length of welded steel pipes used for foundation piles in housing construction, docks, bridges and other foundations.
There are dozens of specifications and models of welded steel pipes for piles. Different specifications and models are adopted according to the needs of piling projects. Below we will introduce in detail the following specifications and models of welded steel pipes for piles. Outside diameter: DN200, DN250, DN300, DN350, DN400 , DN450, DN500, DN600, DN700, DN800, DN900, DN1000, DN1100, DN1200, DN1300, DN1400, DN1500, DN1600, DN1700, DN1800, DN1900, DN2000, DN2200, DN2300, DN2400, DN2500, DN2 600, DN2700, DN2800, DN2900 , DN3000, DN3200, etc. Wall thickness: 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm , 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, etc. Material: Q235A, Q235B, Q235C, Q235D; Q355A, Q355B, Q355C, Q355D, Q355E; Q390A, Q390B, Q390C, Q390D, Q390E, etc. Length: Length is generally in meters, generally including 6 meters, 9 meters, 12 meters, 15 meters, 17 meters, etc. According to different usage requirements, welded steel pipes for piles have specified tensile properties (tensile strength, yield strength or yield point, elongation) as well as hardness and toughness indicators, as well as high and low temperature properties required by users. Spiral seam submerged arc welded pipe is a type of welded steel pipe. It is produced by using internal and external submerged arc welding technology. The steel pipe weld seam is in a spiral shape. Welded steel pipe refers to a steel pipe with seams on the surface that is made by bending and deforming steel strips or steel plates into a circular shape and then welding them.
