WebPipes of DN 800 and larger should be welded internally and externally. The internal weld is the strength weld and the outer is a seal weld. The joint can then be tested by pressurizing the annular space between the two welds (usually with nitrogen at a pressure of 200 kPa); this permits the pipe joints to be tested before backfilling the trench.
