Established in 1993, Guanfa Valve Manufacture Co., Ltd. is specialized China pvc pipe manufacturer and distributor of valves, hoses, tubes and pipes. Our oem pvc pipes are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products. Our high-quality products have been exported to the North Amercia, UK, USA, Germany, Italy, India, France, Australia, Japan.

PVC is the most commonly used plastic material for manufacturing plastic pipe. It has a relatively high tensile strength and modulus of elasticity, and therefore, is stronger and more rigid than most other thermoplastics. Joining methods are by solvent cementing, threading (Schedule 80 only) or flanging. PVC has been used successfully in such areas as chemical processing, industrial plating, chilled water distribution, salt water, chemical drainage, and irrigation systems. Pressure ratings given are for solvent cemented systems. When adding valves, flanges or other components, the system must be derated to the rating of the lowest component: threaded fittings are rated at 50% of solvent cement systems; flanged fittings are rated at 150 psi; union fittings are rated at 235 psi. See manufacturers' recommendations for other ratings.

All Lipson pipes (extrusions) are produced from high-precision German made extrusion lines for high quality consistency and superior product finishing.
Our pipes and fittings can be made, according and conforming to the following International Standards:
1) American Standard (Sch 40 & Sch 80) SDR 21, 26, 41
2) British Standard (BS 3505, 5255, 4515, EN 1452, EN 1401)
