Perforted pipe

Perforated pipes include spiral welded perforated pipe and straight welded perforated pipe. Spiral welded perforated pipes are rolled and welded by perforated metal belts, the belts can be made as buyers' request, like wall thickness, hole size and pitch. Straight welde perforated pipes are made by perforated plate too. Both of the two types of perforated pipes can be manufactured as request, including: wall thickness, pipe diameter, pipe length, hole diameter and opeing area. But after taking test, spiral welded perforated pipes are better in big pressure than straight welded perforated pipe.
