We would like to introduce the "Socket Weld Pipe Fittings End Processing (In-Low Processing)" 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, and small-diameter steel pipes are installed by drilling at a constant small gap around the planned cross-section using methods such as horizontal boring. For the steel pipes used to reinforce the ground with cement milk and other materials, we use a two-thread (lead 20mm) screw that is easy to install. 【Features】 - Tunnel excavation is carried out in advance, and small-diameter steel pipes are installed by drilling at a constant small gap around the planned cross-section using methods such as horizontal boring. - Steel pipes used to reinforce the ground with cement milk and other materials - Easy-to-install two-thread (lead 20mm) screws are used. *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 as well as for steel pipes used in water wells and observation wells, they are equipped with "sawtooth threads," and the joint section has the same inner and outer diameters as the pipe. Additionally, for nominal diameters exceeding 300A, the leading side flange is set to 65° (3 threads/inch) to facilitate fitting. 【Features】 ■ Used for the installation of small-diameter pipes without excavation ■ For pulling method and steel pipes for water wells and observation wells - Equipped with "sawtooth threads," and the joint section has the same inner and outer diameters as the pipe ■ For nominal diameters exceeding 300A - The leading side flange is set to 65° (3 threads/inch) to facilitate fitting *For more details, please refer to the PDF document or feel free to contact us.
