Description of water well screens
Pipe based well screen combines stainless steel or carbon steel casing with continuous slot well screen for additional strength in deep well applications. The pipe strength allows smaller wrap wires to be used, allowing for greater open area.

| Material | Both Stainless steel and carbon steel avaliable |
| Slot shape | Square |
| Slot size | 0.02mm~15mm |
| Connection | threaded ends, welded ends |
Feature:
1. High flow capacity.
The jacket is made of vee wire well screen this allow more water or oil to enter at much lesser frictional head loss and the efficiency of well is improved appreciably.
2. Perfect integral strength and strong anti-deformation ability.
The internal part of filtration jacket is supported by base pipe and the outer protective shroud can be fixed outside the filtration jacket if necessary. The integral strength of base pipe with drilled holes is merely 2~3% less than standard casing or tubing. So it can withstand compression deformation from stratum with sufficient integral strength. Even if local deformation occurs, the gap of compressed part will not be enlarged. It has been proved to be highly reliable on sand control.
stainless steel pipe based well screen/two layers water well screen/ reinforced johnson screen with non-clogging constructionis composed of two parts: the base pipe and the slip-on screen. The base pipe will be perforated with a series of holes drilled to a pre-determined quantity and pattern, to carefully balance flow-capacity at each end for both down-hole handling. The holes are then debarred and the joint cleaned, inspected and treated to give the base pipe a long shelf life. Our slip-on screens are manufactured to very exact diameter, length gauge and the strength tolerances. This is done by selecting the required profile wire and support rod, which determine the flow-capacity and strength of the slip-on screen. For each gauge opening in the screen we select a slightly greater than that of the perforated base pipe. This will give the pipe base screen optimum flow-capacity at minimum pressure drop across the screen. The base pipe, casing or tubing, is selected to API specifications by size, grade and weight for each of your required applications.

Why choose us OASIS pipe based Johnson type water well filter screen?
1)World Class Quality: OASIS provide our clients with high quality water well wire wrapepd screens and related products. OASIS had passed ISO9001:2008 quality control system.
2)Third party inspection: The productive process of OASIS screen is controlled by third party test company such as BV,SGS,etc. or client's representative.
3)Non Standard Screens: We OASIS can supply customer designed and engineered screens according to our clients' requirements.
4)Quick Delivery:OASIS can prepare stock for our regular clients to meet clients' requirement at any time.
5)Lower Maintenance of the Well:The water can pass freely around coarse particles and enters the well. So low maintenance costs with minimal encrustation or build-up of scale.
Inspect of pipe based water well screens
1.when raw materials arrive at our factory, we will inpsect the chemical component and then loaded into our warehouse.
2.our inspector will check during all the procedure.
3. before be packaged, our sales manager will inspect the goods with inspector again, approved ones will be labled and packaged.
4.we have person to inspect the loading into container to avoid damage during transportation.
For every different slot opening a new tooling is necessary. So continuous cylinders are only interesting for large quantities. For lower quantities a cylinder is more cost effective.
