Supply & Demand

Flying cold sawing is a new online cutting technology in H.F. welded tube industry. Compare with the friction heat saw, its most major charateristic is the cold milling principle. The end of the tube is smooth and without burr after cutting off. For high quality requirements, these is no need off-line second treatment. In addition, due to the use of servo tracking technology, cutting length accuracy is higher than the traditional computer flying saw. Dust and noise pollution are obviously reduced in the production prcess.

Stainless steel weld neck flanges adopt integral forging structure and full penetration welding process. Featuring high rigidity, stable structure and excellent sealing performance, they effectively avoid stress concentration and leakage risks. With outstanding corrosion resistance, high temperature and high pressure resistance, as well as anti-fatigue performance, the flanges adapt to harsh working conditions with temperature changes and complex media. Boasting high dimensional accuracy and long service life, they are widely used in petroleum, chemical, power and energy industries, ideal for high-standard pipeline projects and export applications.

Automatic steel pipe stacking machine is used on the end of the steel pipe production line, to complete the collection and stacking the welded pipes automatically. The machine can run stable automatically, reducing the labor intensity, improving the automation level of the production line and effectively improving the production efficiency.
