Engineered for secure, leak-proof HDPE pipe connections across municipal water networks and construction fields in Seoul.
Seoul, as one of Asia's most advanced and densely populated metropolitan areas, is undergoing a rapid modernization of its water management and infrastructure networks. With the Metropolitan Government implementing stricter eco-friendly building codes and focusing on municipal water system upgrades, the demand for durable, non-corrosive, and high-performance piping solutions has reached an all-time high.
The city's commercial and residential developments—particularly in areas like Gangnam, Yeouido, and Guro Digital Complex—require reliable piping system configurations that eliminate leakage risks under heavy structural demands. In these environments, PP (Polypropylene) Compression Fittings rated at PN10 have emerged as the standard solution for connecting High-Density Polyethylene (HDPE) lines. These components eliminate the need for hot-fusion welding, reducing construction time, labor costs, and environmental impacts across regional projects.
Designed for durability and reliability. Below is the performance blueprint of Minde PP Compression Fittings used globally.
| Parameter | PP Compression Fitting Standard (PN10) | Seoul/KS Standards Equivalent | Testing Methodology |
|---|---|---|---|
| Material Composition | High-Grade PP Copolymer (Polypropylene block copolymer) | KS M ISO 15874 / ISO 9001 | FTIR Spectroscopy & Melt Flow Index |
| Nominal Pressure (PN) | 10 Bar (1.0 MPa) at 20°C | PN10 Rating Compliant | Hydrostatic Pressure Testing (ISO 1167) |
| Clamping Ring Material | Polyacetal (POM) high retention strength | High-Tensile Mechanical Grip | Pull-out Resistance Test |
| O-Ring Seal | EPDM / NBR Rubber (Potable Water Grade) | WRAS Certified Drinking Water Safe | Compression Set Analysis |
| Temperature Range | -10°C to +50°C (optimized for freezing conditions) | Fully compatible with Seoul winters | Thermal Cycle Testing (-15°C to 65°C) |
Our PP Compression Fittings utilize an advanced mechanical lock system consisting of a PP body, EPDM O-ring, polypropylene spacer, Polyacetal (POM) split ring (clinching ring), and a PP nut. This configuration guarantees a tight seal that increases in grip as inner pressure fluctuates, making it the perfect assembly for Seoul's sub-surface piping configurations.
We are Ningbo Minde Building Materials Co., LTD., based in Zhejiang Province, China. We are a premier factory specializing in the production of high-performance plastic pipes and matched fittings. Our products are widely used in residential water supply, agricultural irrigation, and underfloor heating systems. We have more than 20 years of experience in this field, providing high quality products and efficient solutions for water supply systems worldwide.
In order to provide households and industrial users with environmentally friendly and high-quality pipes, MINDE uses premium imported raw materials. The company operates a state-of-the-art facility featuring 45 pipe production lines, a fully automated feeding system, 85 high-speed injection molding machines, and advanced testing equipment.
To ensure 100% excellent quality, MINDE has set up three inspection points for product inspection and quality control: raw material inspection, process inspection, and finished product inspection to ensure the perfect quality of all products. The company covers an area of more than 90,000 square meters, with more than 200 employees and a group of excellent technical backbone management personnel.
With high quality and high efficiency, our company has passed ISO9001:2022, ISO14001, CE, British WRAS, Russian GOST and other certifications. Our products are exported to Russia, Ukraine, Southeast Asia, South America, the Middle East and other more than 50 countries.

Yes. Our PP Compression Fittings are manufactured from high-grade raw polypropylene copolymer, certified by global bodies like WRAS (Water Regulations Approval Scheme) and CE. This ensures they do not leach contaminants or alter water odor, matching local standards such as KS M ISO 15874 for safe potable water distribution.
Seoul experiences extreme temperature ranges between hot summers and freezing sub-zero winters (-10°C to +35°C). Our fittings are rated from -10°C up to +50°C and maintain pressure ratings up to 10 Bar (1.0 MPa) at 20°C. For below-freezing installation, correct system expansion joints and insulation are recommended, but the high elasticity of the PP body prevents cracking better than rigid PVC components.
PN10 represents a nominal pressure of 10 Bar (1.0 MPa), which is the standard requirement for residential distribution, surface irrigation, and commercial greywater systems. PN16 (16 Bar) is designed for heavier industrial applications, high-rise supply riser lines, and high-pressure pumping stations. Always check the maximum output pressure of your pump system before selecting structural ratings.
Yes. Minde operates 85 advanced injection molding machines and has a dedicated technical mold development division. We provide full OEM/ODM services, allowing adjustments in product dimensions, thread types (BSP, NPT), body colors, and logo branding. Contact our team to request custom tooling quotes.
Due to Ningbo's geographic proximity to the Port of Incheon and Busan, standard shipping times are highly efficient. Ocean freight typically takes 3 to 7 days port-to-port, while fast customs processing ensures that regional deliveries across Seoul are completed within 2 weeks from production release.
Embracing eco-responsible raw materials and advanced sealing designs for next-generation smart-city infrastructure.
As municipal regulations move closer toward carbon-neutral goals, piping infrastructure suppliers must focus on reducing chemical leaching and optimizing structural life-cycles. At Ningbo Minde, we are continuously refining our technical roadmap. We utilize 100% virgin polypropylene resin and are piloting bio-based copolymers to lower the carbon footprint of structural plastics.
Our structural testing center works alongside global inspection institutes to verify that all joint systems resist structural vibrations. This makes them ideal for seismic zones like the metropolitan regions of South Korea. Additionally, our PP-R hot-water and PE-Xb EVOH lines meet strict environmental criteria, helping projects achieve national green building certifications (such as G-SEED in Korea).
