Steel Pipes Lined & Coated with Polyethylene (SPE)
| In 1998, Kuo-Toong developed the Polyethylene Coated and lined Steel Pipes to meet the requirement of environmental protection. Furthermore, the specified coated method differes from other factories which use wrapping method. The new product is very suitable for anti-corrosive environment. In addition, the specific physical character, chemical stability assure the pipes with the best quality. It can be used to transport any kind of chemicals, gas, petroleum, water conditioning, water supply pipes, sewage pipes, fire pipes, and corrosive fluid conveying pipes. |

| The Advantage of SPE |
Products |
| 1.
The great character of resisting acid, alkali, and chemicals.
2. The best character of electrical isolation and electrical resistance. 3. The good heat isolation. 4. The good ductility and adherent ability. 5. Easy for applying. |
