Groundwater Flows ThroughThe Sand And Gravel AquiferTo The Well ScreenAdvantagesPicturesTensile StrengthThe tensile strength required can be calculated on the basis of pipe weight. In addition to the pipe weight, gravel that getsstuck in the joints during the assembly and settlement phase should be considered in design calculations. The lower loadbearing capacity of screen pipes with slots should be considered when developing the well or when pumping (due to largedifferences in water level). The effect of such pressures cannot be precisely determined. When sinking pipes through claylayers, additional compressive forces are exerted due to swelling clays. This can happen at any depth and in extremecases may cause considerable strain on the material surface. The values indicated in the tables of this brochure are basedon the minimum wall thickness of the pipes, their diameters and material composition.Impact of TemperatureTemperature conditions prevailing during the laying of PVC-U well pipes will influence the mechanical properties of thematerial. High temperature between 30° C and 40° C as indicated by the creep strength in relation to time, the PVC-Umaterial properties provide sufficient safety factor for the intended use. It is however important to determine the otherinfluences while encasing the well pipes with concrete to seal the drill holes. Temperature increases can be caused bythe 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 morethan 30°C and that is within the optimum limits.Packing & DeliveryFAQQ: Are you original manufacturer?A: Yes, we JCDRILL is a official leading manufacture in drilling machinery in China and we havethe whole series products you need.Q: Which payment terms are available to us?A: T/T term or L/C term.
