- Original Technology: Plastic Forming
Burring is a type of forming that was originally used for metal working.
It was used to open holes in sheet metal and then tap them.
We applied this technology to forming piping branch.
Upon a request from the pipe fitting manufacturer that has the highest market share in the world, Araki took a lot of trial and error to find out the piping configurations that were simpler, required less welding, had a longer life, and performed better.
After repeating development and testing, Araki has pioneered this burring forming technique at last.
Conventional pipe branch joint fabrication involves complicated cutting of steel pipes that required difficult welding to create a joint.
With this technique, stress caused by vibrations or corrosion can form cracks in the welds.
- 1) Branch joints can be made in the same diameters as the main pipes, from a minimum of 1/8 inch to a maximum of sixty inches.
- 2) Any kind of metals can be formed, including carbon steel, stainless steel, aluminum, titanium, and even minor metals.
- 3) Forming is not limited to circular branch joints; square branch joints can also be formed.
- 4) The branch joints can have a board thickness of 0.02 inch to 1 inch.
- 5) The thickness of branch joints can be formed within twenty percent of the thickness of the main pipes.
- 1) The number of welds and total bead length can be reduced to less than one-third.
- 2）Quality control can be made easier.
- 3）Workload can be reduced.
- 4) Because the branches have an ideal shape that reduces resistance to all liquids, the performances of both the pressure and the flow rates are improved.
There are many uses for this technology, including pipes for building construction and sanitary pipes, large vacuum vessels, energy supply pipelines, and structural poles.
The wide range of demands will be promising.
