Detailed Product Description: | Cangzhou spiral steel pipe Cangzhou spiral steel pipe manufacturer Welded steel pipe Cangzhou Spiral Steel Pipe Supply: also known as pipe, steel sheet or strip after bending, and then welded. Longitudinal and spiral pipe weld form is divided into. By end-use is divided into general pipe, galvanized pipe, oxygen lance pipe, wire casing, metric pipe, roller pipe, deep well pump tubes, automobile tubes, transformers, pipes, welding thin-walled tube welding Yixingguan and spiral. General pipe: general pipe used to transport low pressure fluid. Use Q195A, Q215A, Q235A steel manufacturing. Can be easy welding mild steel manufacturing. LSAW pipe is steel production, and spiral welded pipe spiral steel pipe hot rolled coil production Spiral Pipe Pump tube Fabric machine pvdf tube. The hot strip rolling process with a series of advantages, with access to the production of high quality steels, metallurgical process capability. For example, in the output bench equipped with a water cooling system to accelerate the cooling, which allows the use of low-alloy composition to reach a special intensity level and low temperature toughness, in order to improve the steel weldability. But the basic steel production plant no. The alloy content of the coil (carbon equivalent) tend to be lower than similar grades of steel plate, which also improves the weldability of the spiral welded pipe. More need to explain that yes, due to the coil of the spiral welded pipe rolling direction is not perpendicular to pipe axis direction (the folder solution depends on the helix angle) of the steel pipe, straight seam steel pipe steel plate rolling direction perpendicular to the pipe axis direction, and thus, the crack resistance of the spiral welded pipe material is superior to straight seam steel pipe. Spiral welded pipe and Longitudinal yield pressure and burst pressure measured and theoretical values ??consistent deviation close. But whether it is the yield pressure or burst pressure, spiral lower than longitudinally welded pipes. Blasting tests also shows spiral welded pipe blasting the mouth of the circumferential deformation rate was significantly greater than the Longitudinal This confirmed that the plastic deformation of the spiral welded pipe than Longitudinal, blasting the mouth is generally confined to a pitch, spiral weld the expansion of the gap from the strong constraints. Spiral welded pipe production is basically the same working conditions, stable continuous process: Longitudinal manufacturing processes is segmented, including the entire board / head / pre-roll / spot / welding / finishing / group process process. This is an important feature of the spiral welded pipe production distinguish it from welded pipe production. http://www.naimoguanjian.com pump tube http://www.thgangguan.com Spiral Pipe http://www.hbthgg.com Spiral Pipe |
