Pipe Base Screen for Water Well

Continuous wedge wire pipe based screens are very effective since they can be manufactured with very small slot size and yet still maintain the necessary open area to minimize friction head loss. Most continuous wire wrap screen is manufactured from stainless steel rather than carbon steel in order to avoid problems which often leads to accelerated corrosion

Advantage of Pipe Base Screen

1) A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone
2) Uninterrupted flow.
3) A uniform and efficient well development due to the continuous slot opening.
4) Good strength, no further support structure needed.s a rigid unit that has high strength and minimum weight. 

 wedge wire pipe based screen has sturdy constriction and good mechanical property. It is used to prevent sands from entering the water.

Inspection of Pipe Base Screen

1) All Dimensions of wedge wier pipe based screen will be checked by our quality inspector, and they also can be inspected by Third Party Inspections or representative appointed by buyer.

2) Wall thickness of coupling material is inspected by Ultrasonic inspection method, and they also be made the Ultrasonic flaw detection

3) Do Destructive Collapse Test and collaspe Strength Test before shipment.

4) If required, the screens will be made pickling and passivation.

5) The whole manufacturing process can be monitored by Third Party Inspection Company and representative appointed by buyer.

6) The screens will be arranged the Pre-shipment Inspection if required.
