Hebei Spiral Steel Pipe Factory
2022-05-07
Hebei Spiral Steel Pipe Factory - The spiral steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. are helical welded steel pipes produced from coiled strip steel. In the production process, the strip steel is fed into the welding unit. After passing through multiple rollers, the strip is gradually rolled into a circular tube blank with an open seam. The pressure of the squeezing rollers is adjusted to reduce the weld gap to between 1 and 3 mm. The ends of the welded joint are machined flat.
Hebei Spiral Steel Pipe Factory - The spiral steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. undergo uniform deformation of the steel plate during forming, resulting in low residual stress and a surface that is less prone to scratching during use. Furthermore, these spiral steel pipes come in a wide range of diameters and dimensions, enabling them to meet diverse customer requirements and offering greater flexibility. In addition, zinc‑steel fence manufacturers would also like to point out here that, due to… Hebei Spiral Steel Pipe Factory - The spiral steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. are produced using double-sided submerged arc welding technology, ensuring that the welds are positioned optimally to meet operational requirements and minimizing edge defects, thereby guaranteeing both welding quality and product integrity.
To Hebei Spiral Steel Pipe Factory - The welds of spiral steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. undergo continuous ultrasonic inspection, followed by manual ultrasonic and X-ray re-inspections. Any detected defects are repaired, after which nondestructive testing is repeated until the defects are confirmed to have been eliminated. To date, the application of spiral pipe technology in mass transfer and separation has been relatively limited.
