Double Wall Weld Steel Tube:
The inner surface of high cleanness, good strength and elongation, showing good re-processing and no leakage in high pressure; anti-blasting in high-pressure, long time anti-corrosion properties after surface treatment. They are the ideal material for condenser, evaporation, automotive tubing. We can supply the users with any length bending tubes and straight steel tubes to meet meet the customer's needs.

Surface Treatment Types:

1. Galvanizing

2. Plastic Tube (PVF) And Epoxy Resin Coated Tube (EPOXY)
Features: Printing PVF or EPOXY on the galvanized and passive steel tube, PVF and EPOXY tube has a strong anti-corrosion ability. They are mainly used in producing high-level automobile.

3. Coated Nylon (PA12) Tube

Features: Zinc Zn- free -chromium passivation – nylon coated (PA12) tubes. They have a strong anti-corrosion capabilities, combined with a solid coating, impact resistance, aesthetic appearance, particularly with the requirements of environmental protection. They are mainly used in the hard tube system of high-level automobile.
