Toshoseiko Co.,Ltd.

We manufacture customized equipment for removing the bead inside welded tubes. 

We manufacture equipment that removes the bead inside pipes that are used in automobile parts and construction materials as soon as the pipes are made. Generally, there are 3 methods of machining: machining, rolling compaction, and rolling. These are selectable according to the needs of the job. Our product is designed specifically for the customer’s pipe-making mill, so it can be easily used in the best conditions possible, including the layout. It can perform machining of general steel pipes as small as diameter 7.6 mm at the minimum. We hope to focus on expanding both domestic and overseas sales channels, as well as advertisements.

Welded pipe interior bead machining equipment design and manufacturing

[Strength of products/technologies]
Customers can select an optimal method from machining, compaction, and rolling for their needs for the removal of beads from welded pipes. We have a wide range of trimmers for internal bead machining equipment. These include mechanical types, hydraulic types that automatically adjust to the internal diameter, and built-in chopper types that shred the severed beads. Machining for small diameter pipes is also possible. This includes general steel pipes as small as diameter 7.6 mm at the minimum. 

[Representative's message]
We are one of the few companies that specialize in removing beads from welded pipes. We developed our own rolling equipment in 2012 and registered it as a new design for practical use. The technology was recognized by the Promotion Services Department of the Tokyo Metropolitan Government, and we have already manufactured an experimental unit. We have improved our other internal bead machining equipment and rolling equipment to add variety to the lineup. In the future we hope to focus on expanding our sales channels, and to advertise both in Japan and abroad so our products will be known to many more customers.
