This is a borehole pipe made of "Super Dima material," which has self-repairing capabilities and high corrosion resistance.
The water collection boring casing pipe RUSTOP is characterized by its high corrosion resistance due to the use of SD/Super Dima, which is more resistant to rust compared to regular steel pipes. It is also more cost-effective than stainless steel pipes, offering excellent cost performance. SD (Super Dima) is a material treated from steel plate that has a high corrosion-resistant coating (gold plating of Zn, AI, Mg, Si) and possesses self-repairing functionality. There are no joint components required, and the inner circumference of the joint section is blatted and processed at the factory, eliminating the need for on-site processing. 【Features】 ○ Resistant to rust; long lifespan of approximately 53 years (high corrosion resistance, less prone to clogging) ○ High strength (resistant to earthquakes) ○ No on-site processing (factory processed) ○ Excellent life cycle cost ○ New technology information provision system [NETIS] registration number CB-110036-A For more details, please contact us or download the catalog.

Company information
At Tokuto Co., Ltd., the Manufacturing Department has been engaged in the production of metal processed parts, focusing on the intake and exhaust valves of large diesel engines. We carry out manufacturing after thorough discussions regarding materials, shapes, and applications. We also handle the procurement of special materials, parts inspection, assembly, and the preparation of documentation such as inspection reports. In the Boring Division, we deal with tools and steel pipes used in drainage boring construction, which is one of the landslide countermeasure works. Until now, Tokuto has primarily focused on PVC pipes and SGP pipes (commonly known as gas pipes). However, due to concerns about clogging caused by breakage during construction and rust that occurs with aging, we have recently been concentrating on expanding the sales of pipes with high corrosion-resistant coatings.
