We would like to introduce the "End Processing (In-Low Processing) of Socket Weld Pipe Fittings" handled by Tohshin Industrial Co., Ltd. One of its features is that it is easier to align the axis compared to butt welding. Welding is easy and can be done reliably, making it account for half of the welding types. 【Features】 ■ Easier to align the axis compared to butt welding ■ Easy to weld ■ Accounts for half of the welding types due to its reliability *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Steel Pipes for Pipe Roof Construction" handled by Tohshin Industrial Co., Ltd. Tunnel excavation is carried out in advance, with small-diameter steel pipes being drilled and installed at a constant small gap around the outer perimeter of the planned cross-section using horizontal boring methods. The steel pipes used for reinforcing the ground with cement milk and other materials employ a two-thread (lead 20mm) screw for easy installation. 【Features】 - Tunnel excavation is carried out in advance, with small-diameter steel pipes being drilled and installed at a constant small gap around the outer perimeter of the planned cross-section using horizontal boring methods. - Steel pipes used for reinforcing the ground with cement milk and other materials utilize a two-thread (lead 20mm) screw for easy installation. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Steel Pipes for Pushing Method" handled by Tohshin Industrial Co., Ltd. These pipes are used for the installation of small-diameter pipes without excavation. For the pulling method and steel pipes for water wells and observation wells, a "sawtooth thread" is applied, and the joint section has the same inner and outer diameter as the pipe. Additionally, for nominal diameters exceeding 300A, the leading flange is set at 65° (3 threads/inch) to facilitate fitting. 【Features】 ■ Used for the installation of small-diameter pipes without excavation ■ For pulling methods and steel pipes for water wells and observation wells - A "sawtooth thread" is applied, and the joint section has the same inner and outer diameter as the pipe ■ For nominal diameters exceeding 300A - The leading flange is set at 65° (3 threads/inch) to facilitate fitting *For more details, please refer to the PDF document or feel free to contact us.
