The Use Of Thick Walled Welded Pipes

Coil pipe is committed to the production of circular joints, longitudinal rings of all kinds of coil pipe and steel pressure Steel Pipe and on the basis of the traditional coil equipment of the same specifications and models. The function of the parameters of the coil equipment is improved by 30%, and the gap that the original traditional coil equipment can not be produced is filled. Can produce more than 400 diameter, wall thickness of 8-100mm steel pipe. The main materials are Q235A, Q345B, 20#,45#,35cimo and 42cimo,16 manganese,16 manganese capacity, general cold-rolled sheet can be used for coil and so on. Product implementation standards: GB/T50205-2001, GB/T3092-2001 and so on. Coil pipe is widely used in petroleum, chemical industry, natural gas transmission, piling and urban water supply, heat supply, gas supply and other projects.

1.Coil Tube is the steel plate through the drum machine to form steel billet, and then through submerged arc welding or electric welding into steel pipe, and then to other shaping equipment sizing shaping, this kind of pipe is a single production efficiency is low, the quality of the pipe is unstable, low dimensional accuracy, but the equipment is simple and less investment. The straight seam Welded pipe equipment has high efficiency, high pipe quality, high precision and good unity, and is the preferred equipment for large-scale production of steel pipes.

2.Mainly used for conveying water, gas, air, oil and heating hot water or steam and other general low pressure fluids and other purposes. It can also be used in mines, exhaust air, exhaust gas, and transport low-pressure corrosive media. The steel sold in Shaanxi Huichuan is from Laixi Steel, Shougang, Baotou Steel, Handan Steel, Ye Steel, Tangshan Steel, Jiujiang Steel, Laixi Steel, Angang Steel, Longgang Ma Steel and other quality assurance steel mills, all in line with national standards.

3.Coil products are widely used in petroleum, chemical industry, natural gas transmission, piling and urban water supply, heat supply, gas supply and other projects. The detection method of thick wall coil pipe is mainly ultrasonic flaw detector, 1, the longitudinal weld on the same tube section of thick wall coil pipe should not be more than two. 2, the group of thick wall coiled pipe butt weld corresponds to the inner wall flush when the nominal diameter is greater than the tube should be sealed welding. In the process of coil processing, the surface damage of the plate should be prevented.
