What is the scope of application of the spiral steel трубы Spiral steel pipes are widely used industrial, Строительная и другие отрасли стали, широко используется в различных областях производства, оба внутри и снаружи, масло, газ, очистные сооружения, вода, водоснабжения и водоотведения, охрана воды проекта строительные рамные с стальных труб, знаки, Накладные расходы мостов и других отраслей промышленности.
1, как правило низкого давления жидкости передачи с шов погруженной дуги Спиральные сварные трубы масштаба на горячие Горячекатаный стальной лист труба заготовки, часто температура спираль формирования, adopting double automatic submerged arc welding or one side welding into legal system for water, газ, air and steam general low-pressure fluid conveying with submerged arc welding steel pipe.
2, low pressure fluid conveying with galvanized welded steel pipe is also called galvanized welded steel pipe, commonly known as the white tube. Is used to transport oil, газ, воздух, water and heating steam, warm water generally low pressure fluid or other purposes such as hot dip galvanized welded butt weld or welding steel pipe. Steel tube wall thickness is divided into ordinary оцинкованная стальная труба and thickening of galvanized steel pipe; To take over the side form is divided into without thread galvanized steel pipe and galvanized steel pipe with screws. Specifications of steel pipe in nominal diameter and nominal diameter is inside diameter of approximation.
3, low pressure fluid conveying in spiral welded pipe steel pipe is also called general welded pipe, commonly known as the clarinet. Is used to transport oil, газ, воздух, water and heating steam and other general low pressure fluid and other purposes of welded steel pipe.
4, pressurized fluid conveying with submerged arc welding spiral pipe scale on hot rolled steel coil tube billet, often spiral shape, with double-sided submerged arc welding method, Сварка, spiral seam steel pipe used for pressurized fluid conveying. Steel tube confined ability, good welding function, through a variety of strict scientific inspection and testing, the use of safe and reliable. Steel pipe diameter is big, high transmission efficiency, and can save laying pipelines. Mainly used for conveying oil, природный газ трубопровод.
