Products Description

Our Advantages

1. Double-Layer Corrosion Protection
Our PVC Coated Tubing features a 316L austenitic stainless steel inner tube and a high-quality PVC outer coating, providing both internal and external corrosion resistance. The stainless steel resists corrosion from chlorides, acids, and chemical media, while the PVC coating effectively protects against moisture, salt spray, and industrial pollution.

2. Weldability and Machinability
The low-carbon 316L stainless steel tubing minimizes the risk of intergranular corrosion after welding and is easy to bend, cut, or weld, making it suitable for complex piping layouts.

3. Surface Treatment
Our stainless steel base tubes undergo pickling and passivation, high-pressure water cleaning, and hot air drying to ensure the tube surface is free of oil and moisture, and that there are no bubbles or peeling risks between the plastic coating and the base material.

4. High Pressure Resistance
Our PVC Coated Tubing base tubes are manufactured using a cold drawing process, ensuring uniform wall thickness and undergoing hydrostatic pressure testing to guarantee pressure resistance and prevent leakage.

5. Customizable Supply Capability
TORICH offers customized sizing services and can provide bending, cutting, tapping, and end finishing services upon request.ASTM, ASME, EN, JIS, and other international standards are available.

6. Packaging and Transportation
Our tubing is packaged with waterproof film and wooden pallets to prevent scratching and damage to the plastic coating during transportation; we offer various transportation methods, including sea, land, and air freight.
