PVC Well Casing Pipe and Screen Pipes are an ideal prodcut for protection of domestic, irrigation, industrial & mining bore wells, keeping out the gravel pack and foreign particals providing clean and clear water from the bore wells.

1. Resistant erode

PVC pipe has stable chemical property, which can resistant most of acid and alkali.

2. Service life long

Traditional pipe service life is 20-30 years. PVC pipe service life is at least 50 years at a set temperature and pressure.

3. Excellent sanitary performance

PVC pipe is produced by used Tin or Ca/Zn stabilizer, its sanitary performance is full according to GB/T17219 standard and Ministry of Health of the People's Republic of China related water criterion.

 

4. PVC pipe has better slotted (bored) rate, strong resistant pressure, larger cross flowing, and is the best choice replace steel and concrete slotted (bored) pipe in many fields.

 

5. Easy installing

PVC slotted (bored) pipe joint form: elastic seal ring joint, cement joint, also crew joint and flange joint. In additional, PVC-M pipe is density low, weight light, lower requirements for worker and construction equipment, construction cost also is lower compared concrete pipe, steel pipe.

6. Inside wall smooth, no furring, flowing easier, no block(n=0.008---0.009),excellent resistant bacteria. It can effectively guarantee pipes long time  straightway. for turning over swash field, PVC-M pipes also easily wash clear.
