PERT Pipe Manufacturer WRAS & WATERMARK Certified AL PERT Tubing
– WRAS & WATERMARK Certified
– ACS, AENOR N, SKZ Certified
Features
PERT (Polyethylene of Raised Temperature resistance) pipe is a flexible, durable, and weldable plastic pipe primarily used in underfloor heating systems, hot and cold water systems, and snow melting systems. It offers a novel solution for high-temperature water delivery and has gained popularity in Europe and America in recent years. Compared to iron or PEX pipes, its material advantages are more appreciated by the market.
• Operating temperature ranges from -10°C (14℉) to 110°C (230℉), widely adaptable to both cold and hot water supply needs.
• Certification and compliance. Ctube PERT pipes comply with WRAS, WaterMark, ACS, AENOR N,, SKZ.
• Easy to Installation. PERT pipes are inherently flexible and can still be installed normally at low temperatures. Furthermore, their weldability significantly reduces the need for fittings, which can substantially reduce installation time and costs.
• Non-toxic and Chemicals-Resistant. PERT pipes are non-toxic, resistant to chemical corrosion, and can withstand high temperatures for over 50 years. This is why they are becoming increasingly popular.

FAQ
What brand of PE-RT raw material do you use?
A reliable manufacturer never compromises on resin. We use strictly 100% virgin material from globally recognized petrochemical giants such as LG Chem (SP980), SK (DX800), or Dow. Buyers should always demand a Certificate of Analysis (COA) for the raw material to ensure they aren’t buying pipes made from mixed regrind plastics that will fail under pressure.
Do you have high-speed extrusion lines to handle urgent mega-projects?
Capacity is a major differentiator. True manufacturers invest in state-of-the-art, multi-layer co-extrusion lines (like KraussMaffei or Battenfeld). We have the capacity to produce over 100,000 meters of 5-layer EVOH PE-RT pipe daily, ensuring your project timeline is never delayed by supply chain bottlenecks.
How do you ensure the EVOH layer is applied evenly during production?
Precision is key. We utilize ultrasonic wall-thickness monitoring systems integrated directly into our extrusion lines. This provides real-time, 360-degree measurement of all 5 layers, ensuring the EVOH barrier and adhesive layers are perfectly concentric and meet DIN 4726 standards throughout the entire coil.
Can you provide OEM printing, custom colors, and specialized packaging?
Absolutely. We offer comprehensive B2B OEM services. This includes custom meter-mark printing with your brand name, specialized pipe colors (e.g., orange, red, blue, or natural), and custom shrink-wrapped packaging or palletization designed to maximize 40HQ container loading efficiency.
What quality control testing is done on PE-RT coils before shipping?
We operate a fully equipped in-house laboratory. Every production batch undergoes strict QA, including:
- Thermal Stability Test (OIT – Oxidation Induction Time).
- Hydrostatic Pressure Testing (to ensure long-term burst resistance).
- Cross-Section Analysis (microscopic verification of layer bonding). We provide comprehensive batch test reports with every bill of lading.
