Welded stainless steel slot pipe

between wire wrapped screen Definition:
wire wrapped well screen pipe is manufactured from two components: 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 wire wrapped screen pipe a long shelf life.Our slip-on screens are manufactured to very exact diameter, length gauge and 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 wire wrapped well screen pipe.

This will give the pipe base screen optimum flow-capacity at minimum pressure drop across the screen.The wire wrapped well screen, casing or tubing, is selected to API specifications by size, grade and weight for each of your required applications.

 

What‘s the difference between wire wrapped screen and Slotted Casing Pipe?

Slotted casing Pipe is a kind of screen which uses various ways to cut out a plurality of longitudinal or helical vertical and staggered slits in the oil casing or tubing. It is made of a special ultra-thin cutting piece and a beam of light. The seam width is 0.2 mm-0.5 mm, the shape of the section is rectangular, trapezoidal or circular hole shape, it can guarantee 0.5%-10% permeability.

 

The gap distribution of oil slotted casing pipe can be customized according to the user’s requirements. The gap of wire wrapped filter pipe can be accurately and arbitrarily wound on the base tube, and the width of the slit can be controlled in 0.15-0.5±0.05 mm, so that the need of sand control is completely satisfied. Stainless steel wire has acid resistance. Anti-alkali, salt corrosion resistance, the gap will not be caused by corrosion of the phenomenon of widening..

 

The inner of the filter sleeve of the slotted tube liner is supported by the base pipe, which has sufficient strength and strong ability to resist deformation. Slotted casing Pipe has good sand-control performance and no blockage, which can effectively improve the quality of oil recovery. Often used in horizontal wells, side drilling, radial branch horizontal wells, open hole, gravel filling screen completion. In foreign countries, similar completion of the use of screen screens up to 90%, is now the special production process of the preferred special supporting pipe..

 

Slotted casing Pipe According to its use can be divided into two categories, the oil slit pipe and mining cut seam pipe, they use a variety of steel-grade pipe, in line with national safety standards, to meet a variety of needs.
Oil slotted casing Pipe, wire wrapped filter Pipe, and other oil screens have their own advantages, users just according to their actual needs to choose.

 

 

Slotted liner well screen for water and oil well Definition:

The slotted liner well screen using in oil exploration can prevent 99% sand, decrease 80% of oil well heavy maintenance, as well increase the strength of the oil well, integrality and stability of keeping sand off. Meanwhile, the laser incision tech can make the slot be smooth and precision. The structure of slotted casing pipe is sample, but it works highly efficient.
