Spiral Pipe Handling

A tight spiral steel pipe has the advantage that only a thin layer of the side appearance to melting, which makes oxides and impurities squeezed to give a pure, high-quality welds. Side parallel link, spiral pipe manufacturers oxide can be extruded along two deflection.

If the inside of the side of the first war, out of the oxide becomes more difficult. Between A, B two points there is a bell, it's like receiving a crucible impurities. Temperature near the inner side of the oxide floating on the central two squeeze rolls molten liquid metal table; the point of the power supply, which can not get excellent quality of the welded joint is formed clip flooded. Spiral pipe manufacturers deal with a larger coefficient of linear expansion of non-ferrous metals (such as aluminum), this dual V-shaped formation of slag not only signs, but also probably produce shrinkage when the metal agglutination crunch led to the formation of pinhole defects. Strip width and welded tube that is blank and select the shape of the groove for the pipe size requirements and guarantee margin squeeze to give excellent quality of the pipe, spiral pipe manufacturers to deal with the material held estimate, in reality production may credentials T formula estimate the width of the strip.
