Steel pipe pile factory in Shantou

Shantou steel pipe pile six manufacturers Liu Bao: 18,033,242,424 18,823,102,210 widely used in steel pile wharf, breakwater, revetment, slipway and other port infrastructure projects. Steel piles into the seabed hammer a certain depth, directly bear the load of the superstructure and seawater corrosion, so its more stringent quality requirements. Take reasonable construction technology and construction method of making steel pipe pile is the prerequisite to ensure project quality. Spiral Pipe is a strip coil for raw materials, often warm extrusion, automatic two-sided double-wire submerged arc welded process spiral pipe joints. (1) raw materials that strip, wire, flux. Go through rigorous physical and chemical testing prior to investment. (2) strip head and tail docking, single or double wire submerged arc welding, in the rolled steel by automatic submerged arc welding. (3) before forming the strip after flattening, cutting, trimming, planing, surface cleaning and transportation to the curved side. (4) the use of electrical contacts on both sides of pressure control conveyor cylinder pressure to ensure the smooth delivery of the strip. (5) the use of internal or external control roll forming. Shantou steel pipe pile manufacturers (6) with gap control device to ensure that the weld gap to meet the welding requirements, diameter, misalignment and weld gap have been strictly controlled. (7) within the welding and soldering are used outside the United States Lincoln welding machine for single or double wire submerged arc welding, thereby obtaining a stable welding specifications. (8) After welding the weld line ultrasonic injury examination was to ensure 100% coverage of non-destructive testing spiral weld. If defects, automatic alarm and spraying tags, production workers and so at any time adjusting the process parameters, and remove defects. (9) using air plasma cutting machine to cut a single tube. (10) cut into a single pipe, each consisting of three steel head first to conduct a rigorous inspection system, the mechanical properties of the weld inspection, chemical composition, fusion status, as well as through the steel surface quality NDT inspection to ensure that the process pipe After passing to formally put into production. (11) there is a continuous acoustic testing marks the site of the weld, manual ultrasonic and X-ray review, if there are defects after repair again after destructive testing, until the confirmation of the defect has been eliminated. (12) strip butt weld, and intersect with spiral weld small joint where the pipe all through the X-ray television or film examination. (13) each pipe after hydrostatic test pressure radial seal. Test pressure and time by a steel pipe pressure microcomputer detection device is strictly controlled. Test parameters are automatically printed records. (14) pipe end machining, so that the end vertical slope altercation and accurate control of the blunt edge.
