Engineered to deliver exceptional thermal conductivity, structural elasticity, and long-term hydrostatic strength under Polish winter climates.
Poland's heating and cooling market is undergoing a historic shift. Prompted by the EU's strict decarbonization mandates and the local "Clean Air" (Czyste Powietrze) program, developers, design institutes, and installation firms across Warsaw, Kraków, and Poznań are rapidly phasing out carbon-heavy heat sources in favor of heat pumps, modern district heating, and hydronic radiant floor heating systems.
At the center of this transformation lies the demand for high-durability polymer systems. Specifically, PE-RT (Polyethylene of Raised Temperature resistance) has emerged as the premier choice over copper and standard PEX. Because of its superb flexibility, thermal-oxidative stability, and cost-effectiveness, PE-RT allows installers to cover wide radiant surfaces with minimal joints, substantially reducing leak risks.
As a leading exporter, we observe that the Polish HVAC landscape requires products that conform to strict German and European performance metrics (such as DIN 4726 oxygen barrier guidelines), prompting our continuous improvement in five-layer EVOH PE-RT technology co-extrusion.
We combine advanced fluid control mechanics with state-of-the-art polymer processing to supply Polish distributors with premium structural integrity.
Our PE-RT pipes integrate an Ethylene Vinyl Alcohol (EVOH) oxygen barrier preventing oxygen ingress into the water system, thus shielding steel boilers and radiators from premature oxidation.
Fully validated for Class 4 (underfloor heating) and Class 5 (high-temperature radiator systems) operations as outlined in standard ISO 22391, guaranteeing structural viability up to 90°C.
Our facility manages a complete lab cycle for raw materials, executing batch-wise creep testing and hydrostatic burst tests to confirm 50+ year service life for commercial installations.
For Polish import firms, design engineers, and construction general contractors, negotiating a sustainable and transparent pricelist is critical. Polymer pricing is susceptible to multiple market forces. Understanding these elements enables purchasing officers to optimize procurement budgets:
Our sales department maintains dynamic pricelists tailored to container-load volumes. We also accommodate custom configurations—including color customizations, length rolls (from 100m to 600m), and OEM brand marking—to give local brands in Poland a distinct commercial advantage.
Established in 1996 in Yuhuan, Zhejiang—known as the plumbing and valve manufacturing hub of China—Yuhuan Yongda Fluid Control Co., Ltd. (formerly Yuhuan Yongda Plumbing Co., Ltd.) has spent nearly three decades refining its design, fabrication, and export workflows. Our factory spans 45,000 square meters, with an operational floor area of 80,000 square meters.
Equipped with over 600 advanced manufacturing and diagnostic machinery sets, including 80 specialized precision CNC units, we maintain complete oversight of brass machining, forging, and polymer extrusion workflows. Our products are segmented into three primary categories: brass valves, technical compression fittings, and specialized HVAC components. By engineering our PE-RT pipelines and corresponding brass manifolds together under one roof, we guarantee optimal tolerances, leak-free compression interfaces, and fluid distribution balance across the entire system.
Designed to comply with European standard EN ISO 22391, our structural specifications cover diverse pressure classifications.
| Nominal Size (OD x Wall) | Application Class (ISO 22391) | Design Pressure (Bar) | Oxygen Permeability (DIN 4726) | Thermal Conductivity (W/m·K) | Standard Roll Lengths |
|---|---|---|---|---|---|
| 16mm x 2.0mm | Class 4 / Class 5 | 6 / 8 Bar | < 0.1 g/m³·d | 0.40 W/m·K | 200m / 300m / 600m |
| 20mm x 2.0mm | Class 4 / Class 5 | 6 Bar | < 0.1 g/m³·d | 0.40 W/m·K | 100m / 200m / 300m |
| 25mm x 2.3mm | Class 4 / Class 5 | 6 / 8 Bar | < 0.1 g/m³·d | 0.40 W/m·K | 50m / 100m |
| 32mm x 2.9mm | Class 4 / Class 5 | 6 / 8 Bar | < 0.1 g/m³·d | 0.40 W/m·K | 50m |
In accordance with Polish national building codes (Prawo Budowlane), piping installations intended for radiant layouts must satisfy strict safety and operational lifetimes. We design and package our products to simplify the validation processes for building control inspections:
Ensure seamless compatibility by using matched system fittings, valves, manifolds, and controls from Cokaren.
At Yuhuan Yongda, we understand that heating pipes hidden beneath concrete floors must operate flawlessly for decades. Even a tiny defect can cause significant damage. This is why our production and QA processes are strictly controlled:
Find answers to common questions about PE-RT piping, pricing structures, compliance, and international shipping.
PE-RT Type II resins are produced using advanced polymer technology, providing higher design stress capabilities and better resistance to elevated temperatures compared to Type I. This makes Type II particularly suitable for commercial heating installations and high-pressure district heating applications.
Plastics are naturally permeable to oxygen. Without an EVOH barrier, oxygen can dissolve into the system water, leading to rust in ferrous components like steel boilers and iron radiators. An integrated EVOH barrier reduces oxygen permeability below DIN 4726 limits (0.1 g/m³/day), protecting the system from internal corrosion.
Pricelists are generally structured on a per-meter basis, influenced by polymer material costs, layer configuration (e.g., 3-layer vs. 5-layer), roll dimensions, and purchase volume. We offer scalable tier discounts for container-load orders to help wholesale partners secure favorable margins in the European market.
Yes, all our pipes and fittings are manufactured to meet European standards. Our pipes comply with EN ISO 22391, and our brass components carry CE certification. We maintain ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications to ensure consistent product quality.
For custom production runs, the typical MOQ is 5,000 meters per size. Standard size orders can often be consolidated into smaller quantities. Typical manufacturing lead times range from 25 to 35 days, followed by sea freight transit to Polish ports like Gdańsk or Gdynia.
