Produce diameter of 219mm-3620mm wall thickness of 5mm to 25mm spiral steel pipe. Annual production capacity of 80,000 tons. North China is the largest manufacturer of the caliber. A strip coil as raw material, often warm spiral shape, double-sided submerged arc welding process to automatically double-wire spiral welded pipe joints. The products are mainly used in gas, oil, water pipelines and steel structures. Each production line are equipped with U.S. production of Lincoln automatic welding machine, the weld grinding machine, chamfering machine, hydraulic test machine, and offline X-ray industrial TV flat head down ensure each pipe welding quality. The high-frequency straight seam welded pipe production lines. Produce 133-159-168 wall thickness 3mm-8mm of high-frequency straight seam welded steel annual production capacity of 60,000 tons. Straight seam welded steel pipe by high-frequency welding unit specifications strip strip rolled into a tube-shaped and straight seam welded steel pipe. Mainly used in civil construction, petrochemicals, light industry and other departments have a wide range of applications. For conveying low pressure fluid or made into a variety of engineering components and light industrial products. To ensure the quality of steel pipe with steel pipe-line ultrasonic testing system at any time to monitor the intrinsic quality of the weld. Double submerged arc welded fingers steel pipe production line. The the most advanced JCOE to straight seam double submerged arc welded pipe equipment, can produce a single slit Φ245mm-1120mm, double-seam steel pipe 2200mm, 3620mm multi-seam steel pipe wall thickness 6mm-60mm of a variety of materials of various standard LSAW steel pipe. Based on leaflets plate as raw material, the steel in the mold or molding machine pressure (volume) into the tube, double-sided submerged arc welding and expanded diameter from production. The finished product specifications over a wide range of weld toughness, ductility, uniformity and dense, with a large diameter, wall thickness, high pressure, low temperature corrosion resistance, etc.. Required in the construction of high-strength, high toughness, high-quality long-distance oil and gas pipelines, mostly large diameter thick wall steel pipe LSAW pipe. According to API standard provisions, in the large-scale oil and gas pipelines, when the alpine zone, the bottom of the sea, urban and densely populated areas, Class 1, Category 2 areas, straight seam submerged arc welded pipe is the only designated for tube pressure fluid delivery with spiral buried arc tube is mainly used to transport oil, natural gas pipelines, pressure steel, plastic, and easy welding and machining molding; low pressure liquid delivery spiral submerged arc welded pipe using double-sided automatic submerged arc welding or welding legal system as for water, gas, air and steam low pressure liquid delivery SAW pipe. Spiral characteristics: Longitudinal production process is simple, high efficiency, low cost, rapid development. The strength of the spiral welded pipe Longitudinal generally higher than can narrow the billet production of large diameter pipe, you can use the same width of the billet production of different diameters of pipe. However, compared with the same length of straight pipe joints, weld length of 30 to 100%, and lower production rate. Therefore, most of the smaller diameter pipe straight seam welded pipe of large diameter are mostly spiral welded. Generally used Coil material: Q235A, Q235B, Q345, L245, L290, X42, X52, X60, X70, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb. The spiral is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the key products of our development of twenty. For the transport of liquids: water supply, drainage, sewage treatment works, transmission and mud, marine conveyance. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: for piling pipe for bridges; docks, roads, building structure pipe, marine piling pipe. The company's products fully comply with the technical requirements of the national standards, according to the international standards of ISO, BS, ASTM, DIN supplier according to user needs. Commitment :: length to provide customers with special requirements, cut, cut, polished grinding services. Quality based on the full implementation of quality management. Quality to win the trust of customers, to meet the market, technology product that is character, integrity is life. Customer satisfaction is our eternal pursuit. The company promises: the same quality steel, steel pipe lowest price, the real benefit to the end user. The site billing - loading - billing the train service, you can complete the whole process of delivery to allow customers to sit in the foyer.
