However, the risk of the test is greater than the hydraulic test. Shorter and longer lengths are available, but for a calculation, it is wise, to use this standard lengths; other sizes are probably more expensive. They both verify the weld density of containers and pipes that work under pressure. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp. It shall include a certified welding inspector AWS QC1 to verify that welders and welding procedures are qualified, procedures are being followed with limitation of testing, and quality-assurance functions are being implemented. To prevent the damage during transportation, pipe ends are covered with a cap. Available Products. X-rays shall be applied to the spiral welds of steel pipes used for the transportation of common fluids such as water, sewage, air and heating steam. The test pressure shall be held for sufficient time to observe the weld seams.
