Product Description

double-deck well screen also named Pipe base casing screen for drinking water well:
Pipe based well screens consist of base pipe, all-welded wedge wire screen and supporting rod. The base pipe is perforated or slotted API casing pipe, the base pipe can be stainless steel or carbon steel API 5CT casing. The all-welded wedge wire screens are welded together with base pipe by supporting rod.

Advantage	from direct factory supply

It is used for sand control in wells with high pressure and high traction value due to the depths.
Having the API casing inside a wire wrap screen jacket is supporting the screen and enhance the cabapitities and high tensil strength Loads.
Pipe base can be made from API pipe Seamless casing spiral or stainless steel casing
Opening area for the base pipe is up to 15% and for the jacket is up to 40%.
Jacket slot size between 0.15mm to 15mm.


Features of Pipe Based Well Screens
1.High filtering accuracy: All-welded wedge wire screens as screen jacket with vee opening design makes the filtering accuracy higher, which can control sand better.
2.Excellent strength and resistance to deformation: The base pipe inside, the outside can be protected with the protection jacket added according to requirements, the integrated strength of the perforated base pipe only decreases 2-3% compared with the standard casing/oil tubing, so the pipe based well screens have enough integrated strength to resist to the pressure caused by strata. Even if some part of the well screens deformed, the slot of this part will not be widened, which makes higher sand control reliability.
3.More choices: The material of screen jacket can be stainless steel or carbon steel, the material can be chosen according to customers' requirements.
4.The smaller slot will increase the oil and gas production.
5.The excellent technique makes the mass production with high efficiency and low cost available.
6.The specifications can be customized according to customers' requirements.
