Nine point production of galvanized pipe fittings
Galvanized pipe oiled marking: the inspection and approval of galvanized pipe oiled operation to prevent corrosion, and marking according to customer requirements.
2. galvanized pipe flattening edge milling: Use anvil machine plate leveling of the original curl, and then through the edge milling machine for two-sided steel milling, so as to meet the requirements of the plate width, plate edge parallelism and slope mouth shape.
3. Cut galvanized pipe forming: steel sheet curled into a tube along the outer edge of galvanizing.
4. Cutting galvanized pipe welded: using double-sided submerged arc welding technology to pre-welding, welding inside and outside welding. The pipe is welded using plasma cut foot length specification.
5. galvanized pipe visual inspection: by professional and technical personnel to some of the basic parameters to be checked.
6. galvanized pipe ultrasonic inspection: internal and external weld and weld on both sides of the base material 100% inspection.
7. X-ray detection galvanized pipe: internal and external welds 100% X-ray industrial TV check image processing system to ensure that the use of detection sensitivity.
8. galvanized pipe pressure test: the hydrostatic testing machine for tube-by-root test to ensure the pipe to test pressure requirements of the standard.
9. galvanized pipe chamfering flat head: galvanized pipe will be inspected after the pipe end processing, to achieve the pipe end beveling size requirements.
