Big Bend is also known as the bends in the pipeline project, according to the different production methods should be divided into: simmer, stamping, welding Big Bend. The simmering Big Bend is divided into cold simmer and heat simmer two, with good stretchability, resistant to high pressure, resistance, etc, which is widely used. Cold simmer Big Bend at room temperature to rely on equipment simmer bend of the tube, the advantage of not requiring heating equipment, not filling sand tube, easy to operate. The heat simmer Big Bend is the more primitive production methods, tube filling sand, and then the tube is heated to simmer Big Bend. The method greater flexibility, but the efficiency is not high, greater energy wastage, high cost. The carbon steel simmer bend less using this method, but there are obvious advantages in the non-ferrous metal pipe and plastic pipe simmer bend. The method process: filling sand, heating, bending, sand. Heat simmer Big Bend for circular steel structure of the building, tunnel support, curved roof beams, subway engineering, aluminum doors and windows, ceiling, package cylindrical skeleton, balcony handrails, shower door, rail lines, fitness equipment and other industries . I long production pipe, Big Bend, cold simmer Big Bend, hot simmer Big Bend, I will be quality products, good service, sincerely look forward to colleagues at home and abroad to visit negotiate, we would like to cooperate with you wholeheartedly, and development, mutual benefit and win-win, service and commitment: responsible for product quality in the product during the warranty period by us free of charge repair or replacement, we will assist the demand side will send a qualified, independent field service personnel to solve the problem, we provide field service personnel can meet the needs of the project.
