Spiral Welded Pipes

Product Details:

Orbit Tradex offers Spiral Welded Steel Pipe, used as long distance conveying pipeline for water, petroleum, natural gas, chemical engineering, electrical power, thermal power, heating power, water supply and drainage, steam heating, as well as pressure tube for hydro power station. It is also adopted in piling, dredge, bridge, steel structure, and other civil constructions. 

Each pipe is hydrostatically tested to a given pressure as per API 5L specification or other desired specification. 100% weld length and HAZ of each pipe is examined by an automatic ultrasonic unit with the help of 16 probes and 16 channels for detecting the defects, if any. At the X-ray station, radiographs are taken of weld seam for each pipe end, to a distance of 4ʺ. Every length of pipe is subjected to a rigorous check at the final stage before it is accepted by the Quality Control Department.
