Lianjiang steel coil tube six processing factories Liu Bao: 18,033,242,424 188,231,022,101. First make sure the former steel coil tube plate thickness, 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 damage other people's eyes, spiral welded pipe: Lianjiang steel coil tube processing factory is the carbon carbon structure steel or low alloy steel strip by a certain helix angle (called molding angle) rolled into a tube and then seam welded pipe is made, it can use a narrow strip production of large diameter pipe. Its specifications diameter * thickness of said pipe should ensure hydrostatic testing, tensile strength and cold bending properties of the weld to be in compliance.
