Patented Bump-Joint Joining Method

The traditional joining method for metal pipes like galvanized steel is by threaded coupling. With this method, in order to achieve the required thread depth to support the pressure at the pipe fitting as well as along the length of the pipe, unnecessary material is added along the full length of the pipe.

Lighter Weight, Higher Quality

Utilizing the innovative LinkPlus USA bump-joint joining method, the pipe wall thickness of our stainless steel pipe can be reduced. This means LinkPlus Stainless Steel pipes weigh 20% of the same diameter galvanized pipe.

LinkPlusCatalogFinal3Figure 3:Press at least two dimples, evenly spaced, into the end of the pipe with the LinkPlus USA Pliers. This ensures that the pipe cannot pull or vibrate out of the fitting.
LinkPlusCatalogFinal4Figure 4:Stretch the silicon seal over the end of the pipe and position it just above the dimples.

Notes:

• Avoid damaging the welded seam of the pipe by making sure to not squeeze the bump on the weld in the pipe.

• The number of bumps required depends on the diameter of the pipe as shown in the following table:

 

Pipe sizeNumber of bumps
1/2" - 3/4"2
1" - 1 1/4"3
1 1/2" - 2" 4
