In the process of forming the spiral welded pipe, the plate deformation is uniform, the residual stress is small, and the surface does not produce scratches. The processing of spiral steel pipe diameter and greater flexibility, the size range of wall thickness, especially in the high-end production of thick walled tube, especially unmatched in small and medium sized thick wall pipe and other methods of spiral steel pipe specifications more advantage to meet user requirements.

With the advanced double submerged arc welding technology, the welding position can be optimized, and it is difficult to control the welding quality, such as wrong edges, welding and non welding.

100%, the quality inspection of steel pipe, make the whole process of steel pipe production under effective inspection and monitoring, effectively guarantee the product quality.

All the equipment and computer data acquisition system of the whole production line have network function to realize real-time data transmission, and the central control room controls the technical parameters in the production process.

(1) small and medium-sized steel, wire, steel, medium diameter steel pipe, wire rope, wire rope, etc., can be stored in a well ventilated greenhouse, but must be placed under the pad.

(2) a number of small steel, thin steel, steel, silicon steel, small diameter or thin-walled steel pipe, all kinds of cold-rolled and cold drawn steel and high price, easy to corrosion of metal products can be stored into the library.

(3) to store spiral steel pipe products on the spot or warehouse, we should choose clean and clean place, away from the production of harmful gas or dust in factories and mines. Remove weeds and all debris on the ground and keep the steel clean.

(4) large steel, rail, stigma plate, large diameter steel pipe, forgings can be piled up.

(5) in the warehouse shall not be combined with acid, alkali, salt, cement and other materials to erode steel. Different kinds of steel should be piled up separately to prevent confusion and prevent contact corrosion.

Requirements of spiral steel pipe superposition principle in stacking stability, under the premise of ensuring safety, do stacking according to varieties, specifications, different types of materials to prevent mud stacking, and mutual erosion;
