Technology characteristics of Spiral Pipe
Spiral steel pipe, also known as helical or spiral tube body. Spiral steel pipe outer diameter of about 30 nm, inner diameter of about 10 nanometers, adjacent helical pitch of about 11 nm. Spiral pipe per one week from the 6 surrounded nucleosome, H1 histone in the inner surface of the spiral steel chamber, to maintain the structure of spiral steel plays an important role. Composed by the nucleosome 10 nm 30 nm fiber to form spiral of crude fiber, so that further compression 6 times the length of DNA. Spiral steel pipe is mainly used for oil, natural gas pipelines, and its specifications diameter * wall thickness. There are one-sided spiral pipe welding and double welding, pipe should ensure hydrostatic testing, tensile strength and cold bending properties of the weld compliance.
1, 100% of the steel quality inspection, so that the whole process of steel production in the effective detection, monitoring under, effectively ensure the product quality.
2, all the equipment the entire production line and computer data acquisition system with networking capabilities, real-time data transmission, from the central control room of the production process technical parameters.
3, the molding process, the steel deformation even small residual stress, surface does not produce scratches. Spiral pipe machining diameter and wall thickness in the range of sizes greater flexibility, especially in the production of high-grade steel thick-walled pipes, especially small and medium-diameter thick-walled tube aspect has the incomparable advantage of other technology, users can meet In the spiral pipe specifications more demanding.
4, the use of advanced double-sided submerged arc welding process, welding can be achieved in the best position, less prone to the wrong side, partial and incomplete penetration welding defects, easy to control weld quality.
