How Ensures High-Quality Capillary Tube Mats During Manufacturing

When a capillary tube mat is embedded inside a ceiling, wall, or floor, it is expected to operate reliably for decades without leakage or performance degradation. Because the system becomes part of the building structure, product quality is critical.

At Sinolanc, quality is not achieved through a single inspection step. It is built into every stage of production—from raw material selection and automated manufacturing to welding control, pressure testing, and final inspection. With more than 18 years of manufacturing experience and fully automatic German production lines, we have developed a comprehensive quality control process to ensure every capillary tube mat meets the highest standards.

1. Premium PPR Raw Materials
Sinolanc uses only high-quality polypropylene random copolymer from Borouge, known for its durability, flexibility, corrosion resistance, and long service life. High-quality raw materials provide the foundation for reliable system performance.

2. Fully Automatic German Production Lines
Sinolanc operates multiple fully automatic German production lines equipped with precision electronic control systems. Automated production minimizes human error, maintains dimensional accuracy, and ensures uniform tube spacing and welding quality across every mat.
This high level of automation allows us to achieve both large-scale production capacity and consistent product performance.

3. Precision Welding Technology
The welded connections between capillary tubes and collector pipes are among the most critical parts of the system.
Over years of production experience, Sinolanc has developed a mature welding process that delivers strong, reliable, and uniform welds. Every welding parameter is carefully controlled to ensure long-term durability and leak-free operation.
Our experienced production team continuously monitors welding quality throughout the manufacturing process.

4. Continuous Process Monitoring and Quality Inspection
Quality control is integrated throughout production rather than relying solely on final inspection.
Key production parameters are monitored and recorded automatically, while quality inspectors perform inspections on appearance, dimensions, and welding quality every sing hour.

5. 100% Pressure Testing for Every Single Mat
One of the most important quality procedures at Sinolanc is our 100% pressure testing policy.
Every capillary tube mat undergoes an individual pressure test before leaving the factory. Each mat is tested at 20 bar pressure for more than 20 minutes. This rigorous testing process verifies the integrity of every weld and connection and ensures leak-free performance. Only products that successfully pass this test are approved for shipment.

6. Certified Quality Management
Sinolanc follows internationally recognized quality management standards and maintains strict manufacturing procedures throughout production. Our products are supported by quality certifications such as ISO 9001 and CE certification, demonstrating our commitment to consistent quality and continuous improvement.

From premium PPR raw materials and German automated production lines to precision welding and 100% pressure testing, every Sinolanc capillary tube mat is manufactured with one goal: delivering reliable performance and long-term peace of mind for every project.
