With recycled PVC pipes, we provide 'peace of mind' through stable supply and stable cost procurement!

<What is recycled PVC pipe?> "A next-generation PVC pipe that is not affected by raw material shortages." "Eliminating procurement anxiety. PVC pipes that keep the site running." Furthermore, with rising raw material costs, the quality remains the same, and the costs are smart! A wise choice! 【Usage Scenarios】 * As beam sleeve material * As underfloor drainage, ventilation, and air ducts * As civil engineering/agricultural rainwater collection and drainage pipes etc. 【Benefits of Introduction】 * Stable supply — Using recycled materials that can be procured domestically to avoid supply instability due to naphtha dependence. * Cost reduction — Less affected by fluctuations in raw material prices, ensuring a continuous supply of low-cost, high-quality piping materials. * Improved social evaluation through waste reduction — Enhancing environmental evaluation by promoting the reuse of PVC waste from construction sites. * Peace of mind with domestic production — Reducing dependence on overseas sources, alleviating logistics risks and procurement lead time concerns. * Long-term price stability — Less susceptible to fluctuations in crude oil prices, enabling long-term cost planning. * Workability equivalent to conventional products — Cutting, bonding, bending, etc., can be performed with the existing JIS standard VP and VU. *For details, please request a catalog from "Contact Us," or view the PDF data from "Download."

Applications/Examples of results

<Other Uses> We have received positive feedback, especially for use as sleeve material, and we propose applications where non-JIS/JIS compliant products can demonstrate their effectiveness on construction sites. - Drainage treatment for land development and exterior construction of buildings - Rainwater drainage within buildings/parking lots - Miscellaneous drainage related to agriculture - Ventilation ducts for buildings - Various types of formwork (sleeve material) - Short-term facilities such as temporary structures etc. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ■ We also offer innovative "labor-saving products" utilizing JIS standard PVC pipes for electrical equipment ■ 'Waterproof sleeve for underground exterior walls "Pipe-In-Sleeve" (abbreviated as PIS)' "Labor-saving construction for underground beam penetration! Enhancing the waterproof performance of buildings!" The underground exterior wall section, with PVC sleeves and FEP outer space, undergoes "waterproof treatment" in advance at the factory and is delivered as prefabricated. No cumbersome work is required on-site; after installation, it fundamentally requires "only joint connections," ensuring stable waterproofing! Achieving work efficiency and "labor-saving" for flood prevention and water resistance. Please download from the related catalog.
