Product Description
Spiral Welded Perforated Pipe is a spiral formed and automatically welded continuous strip metal pipe.
Spiral welded perforated pipe is widely used in many applications and is a filtration product combined with perforated round hole pipe. Our factory provides various pipe diameters and hole sizes for customized types. It is produced using spiral forming and automatic welding of continuous strips of stainless steel or mild steel. This production method, based on high precision and weld quality, permits the manufacture of precise diameter tubes in a virtually unlimited range of variable sizes.
Spiral perforated pipe is also known as spiral welded perforated pipe, spiral perforated pipe, perforated spiral welded pipe, spiral welded perforated pipe.
