Introduction
PVC slotted (bored) characteristics
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.

Material
PVC-U, unplasticised polyvinyl chloride is an ideal material for manufacturing well pipes as it is impervious to corrosion and chemical action, easy to handle and install, light in weight, non-toxic, and non-conductive. Its long service life makes it an economical choice over other materials.

Tensile Strength
The tensile strength required can be calculated on the basis of pipe weight. In addition to the pipe weight, gravel that gets stuck in the joints during the assembly and settlement phase should be considered in design calculations. The lower load bearing capacity of screen pipes with slots should be considered when developing the well or when pumping (due to large differences in water level). The effect of such pressures cannot be precisely determined. When sinking pipes through clay layers, additional compressive forces are exerted due to swelling clays. This can happen at any depth and in extreme cases may cause considerable strain on the material surface. The values indicated in the tables of this brochure are based on the minimum wall thickness of the pipes, their diameters and material composition.
Impact of Temperature
Temperature conditions prevailing during the laying of PVC-U well pipes will influence the mechanical properties of the material. High temperature between 30° C and 40° C as indicated by the creep strength in relation to time, the PVC-U material properties provide sufficient safety factor for the intended use. It is however important to determine the other influences while encasing the well pipes with concrete to seal the drill holes. Temperature increases can be caused by the hydration heat of concrete. Calculations however show that these temperatures do not normally exceed 15°C. With the temperature of unset concrete reaching approx. 18°C, the temperature within the seal will be slightly more than 30°C and that is within the optimum limits.
