With the planning and construction of many major pipeline projects at home and abroad, the pipeline steel has large deformation, high-strength hot bending, low-temperature pipe fittings and other high value-added products with thick specifications and good performance. Market competitiveness and greater market demand have prompted domestic companies to make relatively rapid progress in the development of SSAW pipe piles.
This is the content list:
What is the production principle of SSAW pipe piles?
What are the main uses of SSAW pipe piles?
Introduction to the planning and construction of SSAW pipe piles
SSAW pipe piles is a spiral seam steel pipe made of strip steel coils, which is extruded at room temperature and welded by automatic double-wire double-sided submerged arc welding.
The SSAW pipe piles is sent into the welded pipe unit, through multi-roll rolling, the strip is gradually rolled into a round tube blank with an open gap, the pressure of the pressing roller is adjusted, the welding gap is controlled at 1 ~ 3mm, and the weld Both ends are flush, so as to develop high value-added large deformation pipeline steel as soon as possible, hot bend bend of strip steel, pipeline station with low temperature pipe fittings, X100 direct submerged arc welded pipe, industrial application of spiral submerged arc welded pipe and hot hot bend, SSAW pipe piles.
SSAW pipe piles are mainly used in water supply engineering, petrochemical, chemical, electric power, agricultural irrigation, and urban construction. It is one of the 20 key products developed in China. For liquid transportation: water supply, drainage. Natural gas transportation: natural gas, steam, liquefied petroleum gas. Structural use: SSAW pipe piles such as piling pipes, bridges; docks, roads, building structure pipes, etc. are also used in sewage treatment, water purification, water plants, power plants, chemical enterprises, nuclear power, conveying combustible fluids, and conveying non-combustible liquids.
National standard SSAW pipe piles, SSAW pipe piles according to Ministry of Petroleum standard SY/T5037. The product uses hot-rolled steel strip as raw material, spirally formed at room temperature, and is welded by automatic submerged arc welding. It is mainly used to transport flammable and non-flammable fluids and steel structures in the oil and natural gas industry. It is widely used in civil engineering construction such as houses, bridges and roads. Main production areas: China's spiral pipe manufacturers are mainly located in North China and Northeast China.
With the development of the national economy and the improvement of people’s living standards, SSAW pipe piles equipment has become a new trend in the world today. With the development of domestic pipeline systems, SSAW pipe piles are widely used in long-distance pipelines, piling, dredging, bridges, and steel structures. And other engineering fields, such as natural gas, petroleum, chemical industry, electricity, heating, water supply and drainage, steam heating, pressure pipes, etc. The quality of SSAW pipe piles used in hydroelectric power stations, thermal power generation, water sources, etc. is good or bad, the beams are thin and low, and often insufficient filling. The reason is that the manufacturer has obtained a large negative tolerance. The first few batches of finished products passed under high pressure, with small iron shapes and unfilled holes. Jiangsu Shunli Steel Pipe Manufacturing Co., Ltd. has been focusing on the quality of SSAW pipe piles, the treatment and management of difficult products, and the production of various difficult products. Welded pipe business. Our goal is to achieve the most perfect value for our customers!
