Lock Seam Pipe Welded Pipe Chicago Metal Rolled Products
The lock seam, which is very strong, is made by first edging the material by bending one side of the end of the pipe down and bending the other side up. The two ends are then rolled into a cylinder where the edges interlock with each other. The edges are then mechanically locked by applying pressure along the length of the seam.
Round Spiral Duct for HVAC Duct Systems Fabricator
The 4 ply spiral lock seams of spiral duct create a product that is stronger than traditional welded seam round ducts of the same gauge. Spiral lock seams have practically no leakage, and are the only mechanical seams exempted from sealing under energy standards such as ASHRAE Standard 90.1 2013. At Spiral Pipe of Texas, we make products

Spiral Lock Seam Perforated Metal Tube a Cost Efficient
Lock seam perforated pipe is made by folding up the overlapping edges against each other, then folding them over in the same direction a number of times. It has flush surface outside and lock seam inside. This type perforated tubing is the popular option of fluid filtration like center tube in the filter house.
Lockseam Spiralweld Pipe Naylor Pipe Company
Naylor Lockseam Spiralweld Pipe incorporates a safety factor found in no other pipe. When strains are put on the line, the heel of the lockseam moves minutely, shortening or lengthening the pipe. Because the heel is in spiral form, it acts as a continuous expansion joint throughout the line.
