In the process of producing??sprial steel pipe,?a series of matters need attention. In addition to the following test items, according to API standards and other relevant standards and the special requirements of some users, also need to damage inspection and other steel plates, steel pipes , including physical and chemical properties of raw materials into the factory sampling, 100% of steel plate appearance inspection.
1. Oil marking: qualified after oil to prevent corrosion of steel pipe, and according to user requirements for marking.
2. Leveling of edge milling: through YaZhen machine to make the original curly steel flat, again through the two edges of the steel plate edge milling machine double-sided milling, make it meet the requirements of plate, plate edge parallelism and groove shape.
3. The shear forming: in production line, general steel plate along the outside along the spiral curls into a tube.
4. The butt welding cutting: the adoption of advanced double-sided submerged arc welding technology in welding , welding, welding. The welding of steel pipe used in plasma feet cut into standard length.

7. X-ray flaw detection: the inside and outside welds are 100% of the X-ray industrial TV inspection, using image processing system to ensure the sensitivity of detection.
8. Suppression test: on the hydraulic test machine for steel pipe by root test to ensure the test pressure of steel tube meet the standard requirements.
9. Chamfering flat: after the inspection of steel pipe to pipe processing, meet the requirements of tube end groove size.
10. The last check: again on ultrasound and X ray flaw detection and pipe end magnetic powder inspection, check whether the welding problems and tube defects.
