Detailed Product Description: | Cangzhou pipe production which Tianhui Steel Pipe Manufacturing Co., Ltd. specialized in producing spiral www.thgangguan.com www.bengguan168.com www.naimoguanjian.com www.hbthgg.com The company has consistently adhered to the advanced equipment and technology to the quality of survival, quality and development, to management for efficiency "business principles; and constantly open up new markets, new channels a long time with our clients to establish a good relationship, the majority of customers praise. ? (Executive standard APISpec5L, GB/T9711.1-1997? The SY/T5037-2000) Size (mm) Material: Q235, Q345, coil, and its specification classification: pressurized fluid walks spiral submerged arc welded steel pipes (SY5036 -83) is mainly used for walks petroleum and natural gas pipelines; pressure fluid recommended for admission to the high-frequency welded steel pipe (SY5038-83), with spiral welded with high frequency lap welding method for the pressure fluid walks spiral seam high-frequency welded steel pipe. Pipe pressure can be strong, good plasticity, ease of welding and molding process; ordinary low-pressure fluid walks Spiral Welded Steel Pipe (SY5037-83), using double-sided automatic submerged arc welding or single-sided welding into the legal system for water, ordinary low-pressure gas, air and steam fluid walks SAW pipe. Welded steel pipe: 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. Q195A, Q215A, Q235A steel manufacturing. Can be easy welding mild steel manufacturing. LSAW steel production, and spiral welded pipe production of hot rolled coil. 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 essentially stable under the same working conditions |
