Product Details


spiral pipe holes The spiral Angle of the spiral welded pipe weld is generally 50-75 degrees, so the synthetic stress at the spiral welded seam is 60-85% of the main stress of the straight welded pipe.Under the same working pressure, the wall thickness of spiral welded pipe with the same diameter can be reduced than that of straight welded pipe.

The weld wall of spiral welded steel tube is opened in the direction of main stress. After the steel tube is subjected to internal pressure, the main stress is circumferential stress.5. The impact toughness of steel tube in the rolling direction is very good, while that in the vertical rolling direction is several times different.The toughness weakness of spiral welded steel pipe avoids the main stress, but the toughness weakness of straight welded steel pipe is exactly where the main stress ACTS.
