Stainless steel perforated pipe / perforated tube for sand control
Description
Stainless steel perforated pipe is also called brige slotted screen pipe, it has the bridge openings arranged in rows and are staggered to reduce the negative effect on the screen’s strength. Typically the slots are punched in a flat sheet that is subsequently rolled into a tube and welded. Regarded as the best choice of well tube filter, they are widely applied in a variety of fields in the developed countries.

Advantage
1. Higher collapse resistance.
2. Higher load strength.
3. Easily controlled open area for regulated flow rates.
4. Threaded Fittings in any specifications required.
5. Base pipes can be manufactured using stainless steel grades series or API 5CT carbon steel casing.
6. The pipe based well screens are recommended when high collapse resistance is required and when the screens’ length generates a high longitudinal constraint. The pipe strength allows smaller wrap wires to be used, yielding greater open area.
Application Scope of The Products
Sand screen can be used for vertical wells, the inclined shaft, horizontal wells and various gas, oil and water wells. Can be used individually as sand control tube, also can be used together with filling.
From the inside to the outside, the screen is made with the composite sand filtration kits, stainless steel protection kits and other components. The basic tube is API casing or tubing, sand control filters are stainless steel precision porous filter composite materials, made of the whole welded structure. Because of high penetration, high-intensity, high resistance to deformation, high reliability, good corrosion resistance, the new type of sand control screen has excellent performance property. It is the result of a highly effective new technology in mechanical sand control. This is also our patented product.
