Shock-Resistant PPR Pipes For Plumbing And Drainage Systems

Introduction of Shock-Resistant PPR Pipes

‌PPR (random copolymer polypropylene) pipes are high-performance plastic pipe systems specially designed for hot and cold water transportation, with high-temperature resistance (≤95℃), resistenza à a corrosione, long life (50 anni +), and other characteristics. The ‌ three-layer composite structure ‌ (outer layer UV resistance, middle layer pressure, inner layer antibacterial) is ideally suited to the high standard of building and municipal engineering in Japan.

The compulsory certification requirement of the Japanese market (the latest in 2025) ‌

‌JIS A 2021 Certification: Japanese industry standard, verifying pipeline pressure (≥2.0MPa), dimensional accuracy (outer diameter error ±0.3mm), and thermal stability (95℃/1000 hours strength retention rate ≥80%).

‌JWWA Certification: Japan Watercourse Association drinking water safety certification requires lead and cadmium dissolution of less than 0.01mg/L and 0.005mg/L, respectively (stricter than China GB/T standard 50%).

‌MLIT Certification: Ministry of Soil and Transport building code certification to ensure that the pipeline is in accordance with the “Building Standards Law” Article 38 fire and seismic requirements.

Technical advantages and innovative design‌

Extreme security ‌

0 Dissolution of Heavy Metals: Food-grade raw materials (in accordance with Article 30 of the Food Hygiene Law of Japan) have passed the test of the Tokyo Health and Safety Research Center.

Patented Earthquake-Resistant Design: The built-in flexible connector can withstand the shock of a 30-year earthquake cycle according to the JIS Z 8703 simulated seismic degree 7 test.

High Efficiency And Energy Saving‌

Heat Loss Reduced By 40%‌: Compared with metal pipe insulation performance 2x, suitable for geothermal heating systems in Japan.

Lightweight Installation: The DN25 pipeline weighs only 0.32kg/m (iron pipe 1.2kg/m), which reduces the construction labor cost.

The Internet of Smart Things ‌

‌IoT Pipe Fitting System: Equipped with a temperature/pressure sensor, the data is directly connected to the building BIM management platform, real-time monitoring of leakage and energy consumption.

FAQ of Shock-Resistant PPR Pipes| 

FAQs for Japanese customers

‌Q1: Do PPR tubes comply with Japanese seismic regulations? ‌

Fully compliant! The products have passed the BL Institute test designated by the Ministry of Land, Infrastructure and Transport, meet the requirements of the “Construction Standards Law Enforcement Order” Article 88 seismic grade 3 or above, and provide a 10-year seismic performance warranty.

‌Q2: Is the pipeline connection method suitable for the existing construction standards in Japan? ‌

We support hot melt sockets and ELECTRIC melt pipe fittings, two construction methods compatible with 90% of the Japanese brand welding machines (such as RIDGID and OSAKA ELECTRIC). We also provide JIS B 2305 standard construction training.

‌Q3: How to cope with the extreme cold weather in winter in Japan? ‌

DN20 and above pipelines are equipped with a standard anti-freeze layer (-35℃ anti-freeze crack) and provide the Hokkaido area’s unique anti-freeze program (including a tropical integrated system).

‌Q4: What are the environmental protection certifications? ‌

Achieved:

RoHS 2.0 (Heavy Metal restrictions)

REACH SVHC 235 (EU Chemical Substances Control)
