Anti-corrosion insulation double submerged arc welded pipe is a Steel Pipe in different working environments ensure double-sided buried arc welding and surface temperature at the same time to slow down or prevent in the chemical and electrochemical effects of medium or by the metabolic activity of microorganisms has been eroded and deterioration of insulation anti-corrosion measures.
Introduction of Saw Pipe
1.the air plasma cutting machine to cut a single pipe.
2. into a single tube, each batch of steel tube head to strict inspection system first, check the weld mechanical properties, chemical composition, blending, surface quality of steel pipe and after nondestructive inspection, to ensure that the pipe manufacturing technology qualified, can be formally put into production.
3. in the weld on the site of continuous acoustic inspection marks, after manual ultrasound and X ray review, if there are defects, after repair, once again after the non destructive testing, until the defects have been eliminated.
4. strip butt weld and intersecting and spiral seam D connector tube, all through X ray TV or film examination.
5. each pipe is tested by hydrostatic pressure, and the pressure is sealed by radial seal. The test pressure and time are strictly controlled by the steel pipe water pressure computer testing device. Automatic print record of test parameters.
6. the pipe end machining, the end verticality, accurate control of slope angle and blunt edge.
Submerged arc Welded Steel Pipe and its standard classification: pressurized fluid transportation of spiral submerged arc welded steel pipe (SY5036-83) is mainly used for oil and natural gas pipeline; pressure fluid transportation with spiral welded steel pipe (sy5038-83), with high frequency welding method of lap welding, used for pressure flow transport of spiral seam high frequency welding steel tube. Steel pipe pressure ability, good plasticity, facilitate welding molding and processing; generally low voltage liquid transportation with spiral submerged arc welded steel pipe (SY5037-83), using double-sided automatic buried arc welding or welding was made for water, gas, air and steam general low-pressure fluid conveying submerged arc welded steel pipe.
Besides above the general specifications, we can also supply some specific pipes and other similar steel structure as clients' requirements.
