The advantages of thin – walled spiral tubes and two ways of connectionFebruary 24, 2017
2017: A Promising Year for China’s SteelFebruary 24, 2017
What is the scope of application of the spiral steel tubes Spiral steel pipes are widely used industrial, construction and other industries of steel, is widely used in various production areas, both inside and outside, oil, gas, sewage treatment plant, water, water supply and drainage, water conservancy project construction pile driving with steel tube, the signs, overhead Bridges and other industries.
1, generally low pressure fluid conveying with seam submerged arc spiral welded pipe scale on hot rolled steel coil tube billet, often temperature spiral forming, adopting double automatic submerged arc welding or one side welding into legal system for water, gas, 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, gas, air, 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 galvanized steel pipe 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, gas, air, 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, welding, 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, natural gas pipeline.
