Liu Bao six: 18033242424 The company has three of the advanced US Lincoln spiral pipe production lines, production diameter φ159-φ2820mm (wall thickness 5mm-30mm) double-sided spiral submerged arc welded steel pipe, the annual production capacity of 150,000 tons. Strong technical force, with advanced production equipment. Spiral spiral pipe spiral pipe production specifications thickness 6mm-20mm diameter 219mm-2820mm multiple steel production volume of the machine specifications thickness 6mm-40mm diameter 219mm-5020mm large diameter thick wall steel pipe Welcome to inquire quotes, products can be cut to length length, Companies with a preservative plants, specialty steel pipe outer wall corrosion process, there are three main oil pipe wall two cloth, five oil three cloth, coal tar epoxy and epoxy paint, various polymer coatings. There are non-toxic drinking water pipe wall paint IPN8710-2B, cement and various epoxy coatings. Also known as spiral or helical spiral steel pipe, is a low carbon steel or low alloy steel strip by a certain helix angle (called molding angle) rolled into a tube and then seam welded pipe made It can be produced with a narrow strip of large diameter steel pipe. Spiral characteristics: Longitudinal production process is simple, high efficiency, low cost, rapid development. Spiral Welded Longitudinal generally higher than high, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight pipe seam weld length of 30 to 100%, and lower production rate. Therefore, smaller diameter pipe were powered by straight seam welded, large diameter spiral welded pipe for the most. Spiral mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of 20 key product of development. For the transport of liquids: water supply, drainage, sewage treatment works, transport mud, sea water. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe, for bridges; piers, roads, buildings structure tube, pipe and other marine piling steel coil tube coil tube sheet before the first confirmation of the thickness of steel, the material must meet the design requirements. Must be reasonable under the steel material cutting, reduce waste materials, such as steel cutting when using oxyacetylene cutting mouth clean to be processed. When steel groove, using angle grinder for grinding. 2. When steel coil tube, to make die according to the diameter size. Roll board must be installed in place of acceptance, distribution boxes and cables subject to temporary power specifications. Such as the use of electric hoist, electric hoist can be used after harvest qualified experience. Roll plate machine running noise to be monitored environmental protection department. 3. Group reel, the first reel to be corrected, inspection perimeter diameter. Must correctly when using the hand hammer, nighttime construction noise note shall not affect the residents. Pipeline welding, diffusion of smoke is very important, especially welded pipe wall, make sure the welder does not smoke poisoning in the tube, there must be well ventilated. Side was the construction. 4. Perimeter deviation and roundness deviation reel see GB50235-97 specifications. 5. Volume control group of welding, welding sparks to note, the construction site to be equipped with fire-fighting equipment, welding arc must be blocked, not harmful to the eyes of other people.
