[Electrical Equipment Construction] Flood Prevention! Underground Exterior Wall "Pipe-in-Sleeve T-Type"

Streamlining on-site work through prefabrication! Achieving reduced construction time and improved quality.

[Coming Soon] An upgraded version of the "Pipe-in-Sleeve" that you have come to love! "Pipe-in-Sleeve T-Type," abbreviated as PIS-T In contrast to the PVC sleeve, a through pipe made of FEP has been pre-filled with waterproof material (sealant) at the factory, making it prefabricated. The T-type further features a "drainage PVC flange" welded with PVC material on the outer layer of the PVC sleeve. This method serves as an alternative to the ring-shaped or band-shaped waterproofing material on the outer circumference of the PVC sleeve, responding to strong requests from construction companies. <Features> ■ Excellent waterproofing through prefabrication: Promoting flood prevention and water resistance ■ Labor-saving at construction sites! Reducing the burden on workers and preventing troubles in advance! ■ No skilled techniques required! Simplifying complex tasks! ■ Flexibility to accommodate individual design specifications of projects! ■ Improved work efficiency, standardized quality, and enhanced maintenance! [For Designers and Contractors] FEP pull-through, bell mouth terminal installation, etc., can be arranged according to individual site specifications! Additionally, it is equipped to handle unexpected leaks! A versatile and highly adaptable product that also boasts maintenance and serviceability. *For details, please request the catalog from "Contact Us," or view the PDF data from "Download."

<Specifications> ●Waterproofing ・Test value (smooth inner surface pipe) 0.1MPa×72 hours (This product does not guarantee complete waterproofing) ◆PVC sleeve outer circumference "drainage flange" 6mm thick * 50mm wide welded with the same material◆ ●Composition ・Sleeve material: Rigid polyvinyl chloride pipe (JIS K 6741) VU pipe ・Sleeve penetration pipe: Underground buried electrical wire protection pipe, Furukawa Electric Co., Ltd. Eflex (or flame-retardant Eflex) ・Sealing material: Cured waterproof material filled in two locations <Notes> * The waterproof test is conducted at the penetration gap, not at the "drainage flange" part. * Please select FEP/penetration pipe connection materials from Furukawa Electric Co., Ltd. Eflex series. * The "waterproof performance" of the sealing material (cured waterproof material) is an internal measurement value and is not a guaranteed value.

Applications/Examples of results

*R2.6 Publication of National Transportation Document "Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings" *R3.4 (Public Foundation) Japan Sewerage New Technology Organization "Promotion of Waterproofing (Final Version)" The adoption of these measures is rapidly increasing in construction projects. "Pipe-in-Sleeve (PIS)" <Excerpt of Adoption Records by Local Governments> (Statistics from January to March 2026) - Osaka Prefecture, City of ●●: Communication equipment and other construction work related to the expansion of ●●●● - Shizuoka Prefecture, City of ●●: Electrical equipment construction for the (tentative name) ●● District Center in fiscal year 2027 - Kyoto Prefecture, City of ●●: Electrical equipment construction related to the new building construction of ●● City Hospital (Section 1) - Kanagawa Prefecture, City of ●●: Electrical equipment construction for the expansion of ●● Elementary School building, part 1, etc. Due to the recent shortage of construction workers and skilled labor, while "easy installation" is possible, there are also materials and methods that underestimate waterproof performance, leading to an increasing trend in leakage problems with underground beams in recent years. To prevent leakage accidents from resulting in large-scale repair work later on, we advocate for the adoption of Pipe-in-Sleeve (abbreviated as PIS), which combines both "labor-saving at construction sites" and "the soundness of waterproof performance in buildings," as well as Pipe-in-Sleeve T-type (abbreviated as PIS-T).
