Supply of high-frequency thin-walled tube | high frequency thin-walled tubes | Xin-frequency welded pipe

Shandong Liaocheng Juxin variety of pipe (round, square, rectangular tube, oval tube), and is scheduled for a variety of special-shaped pipe, small diameter thin-walled pipe, galvanized pipe to within the burr and a variety of cold-rolled strip, sheet and the like. Pipe products using high grade steel, all kinds of physical and chemical indicators have reached the national standard pipe, pipe products are widely used in boilers, automobiles, ships, construction of light structural steel doors and windows, furniture, all kinds of agricultural machinery, scaffolding, wire threading pipe , top shelf and container. Can meet customer requirements for high-frequency straight seam thin-walled tubes, welded special specifications according to user requirements for processing. Complete product specifications, strong technical force, advanced equipment and process rational, scientific production management, and can prompt delivery, emphasize credibility, the implementation of small-volume, multi-species, the principle of small profits. 1. The definition of large-caliber large-caliber Longitudinal Longitudinal generally refers to more than the outer diameter of 500mm Longitudinal, currently the largest diameter double seam can reach 2020mm, the largest single weld diameter up to 1220mm. 2. Large-caliber Longitudinal standards and material standards generally use large-caliber Longitudinal domestic GB / T3091-2008, GB / T9711.1-1997, API 5L standards. Materials used are made of large diameter longitudinally welded pipes Q235A, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X70, X80,0Cr13,1Cr17,00Cr19Ni11,1Cr18Ni9,0Cr18Ni11Nb3. Large-caliber Longitudinal process large diameter longitudinally welded pipes mainly produce double submerged arc welding technology-based products by bending, seam, welding inside and outside welding, straightening, flat top multi-channel processes, meet the relevant standards. 4. Large-caliber Longitudinal use large-caliber Longitudinal large pipeline projects, water gas project, the best choice for high-frequency distribution network construction thin-walled tubes, the West-East countries use this type of steel up to 20 tons, the market prospects broad. 5. Quality inspection according to GB / T3091-2008 "low pressure liquid delivery welded steel pipe" standards requirements of high-frequency thin-walled tube monopoly, should be smooth inside and outside surfaces of steel thin-walled tube model of high-frequency, does not allow folding, cracks, delamination, take welding, arc breaking, burn and other depth thickness deviation exceeds the allowable depth of no more than partial thickness deviation under other defect exists. Pipe should do mechanical tests, tensile test, bending test, flattening test, guided bend test and a hydraulic test, and to meet the requirements of the standard. Pipe should be able to withstand a certain internal pressure, the maximum test pressure is 5.05Mpa, holding time is not less than 5S, experiment, pipe leakage does not occur. Welded Steel Pipe allows ultrasonic testing or eddy current testing instead of hydraulic test. SAW pipe allows ultrasonic testing or ray detection test instead of hydraulic test.
