Spiral Submerged-arc Welded Quality Assurance

Spiral welded pipe production by submerged arc method is based on using tandem welding technique for joining inside and outside coil edges, which have been trimmed and beveled by carbide milling for high quality weld structure.

Listing some notes You must know
Note:

Welding of hot rolled steel coils takes spiral form after passing through preforming and forming rolls. Excellent exterior weld quality at high production speeds is provided by double submerged arc welding process. Manufactured pipes are cut to the desired lengths at the exit of the pipe machine. Pipe ends are beveled by means of carbide machining for accurate on-site welding.

After the pipe is conveyed to hydrostatic testing and off-line ultrasonic testing and/or real time X-ray inspection, the pipe will be subject to final inspection for the compliance to customer requirements.

Starting from incoming control up to the final inspection stage; entire process is monitored and supported by computerized system. Traceability is achieved by input controls and barcodes through entire production lines.

SSAW pipes success stories

Widely preferred longer lengths up to 18,5 m. considerably decreases the cost of pipeline construction resulting in less number of girth welds compared to shorter pipe lengths.

Spiral welded steel pipes are widely used in Oil, Natural Gas, Water and other flammable & nonflammable liquid conveyance and distribution pipelines, steel structures for construction and other general purposes by means of their wide size range.

Galvanized pipe process characteristics

What is Galvanized Steel Pipe? Galvanized steel can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements. It has been used used for water-supply pipes or as a strong tubing for outdoor applications.
