Product Description

Spiral Welded Perforated Tube

Holic^® offers Spiral Welded Perforated Tube. Holic^® has developed a proprietary manufacturing process that incorporates spiral welding. Spiral welding is a more challenging production technique which can bring good benefits for the finished products.

Fine opening welded tubing is also used to work singly as well screen or sand control screen for water treatment.

Perforated Patterns

The majority of the patterns shown within each section represent the most commonly used patterns that our existing tooling produces. Due to the versatility of the tools and presses, it is not practical to show every possible pattern that can be produced. Because of the vast number of patterns that can be produced from our tools, it is likely that your requirement can be fulfilled with existing tooling.

In the event we can not produce a pattern with existing tooling, the Customer Service Representative will either quote the closest alternate and/or obtain the price to have our on-site tool and die shop build a proprietary tool.
