Product Description Product Description Product DescriptionBridge slot water well screen pipe:The sand and gravel can't easily block the slot because of bridge slotted screen's special bridge slot design. Bridge type water well screen slotted pipe has great mechanical strength and water entering capacity. Meanwhile, bridge type water well screen slotted pipes use steel punching technology and rolled in many ways, so bridge slotted screen is light, cheap and easily operating. We use Computerized Numerical Control to punch the productive process, so the slot size can be changed as your requirements. In order to give customers more convenience, we can offer any diameter bridge type water well screen slotted pipe, we also offer galvanized bridge slotted screen pipes to prolong the operational life.Product ParametersBasic material----Stainless steel, different qualities depending on ground water properties and temperature.Steel - mild steel, preferably S235JR or similar steel with good weldability properties. Suitable for drawdown wells. Not approved for drinking water.Steel - galvanized, S235JR as base material. Only suitable to a limited extent for contact with drinking water.Steel - coated plastic , S235JR as base material, Rilsancoated, approved for drinking water. Meets the KTW recommendation of the German Federal Department of Health.The slot width tolerance compliant to DIN is +/- 0.2 mm,which means the values listed above for the open area areapproximate values. Approx. 2 mm minimum opening for galvanized andRilsan-coated screens, since the bridge openingscould otherwise plug due to the coating process.Selection of slot sizeAquifer classificationgravelRough sandMedium sandFine sandMealy sandScreening results (mm)1-2.50.5-10.25-0.50.1-0.250.1-0.25Bridge slots (mm)31.5-2110.75Filling gravel spec (mm)4-202-82-32-32-3Filling gravel thickness (mm)75-100100100-200100-200100-200Types-----The different type of Bridge slot screen pipeDiameter(mm)146159219273325377426529ID(mm)130140138200198254250246305300297357350346406400398502500498Thickness(mm)55656568568568568678Coupling OD(mm)146160162220226274278278325328329377378379426428432529530531ConnectionsSelecting the best connection---- The choice of connections largely depends on technical requirements such as tensile strength, collapse resistance, andinstallation guidelines for construction sites.In addition, the outer diameter of the respective connectionshould be considered also, which is larger than the pipediameter.Our AdvantagesHigh strength through resistance to twisting, compressive, and tensile forces A smooth bore that does not impede the passage of probes, tools, etc. Formations with large particle sizesLarge diameter wells Low to medium flow rates Product scope of application
