Specifications

High density charge screen  pipe

Product name: high density flushing joints screen

Screen is made of high density flushing Joint Center pipe, high density red sewing set, consisting of stainless steel ring, with precision control of porosity, area of exceeding flowing is big, overall strength and anti-distortion ability, excellent corrosion resistance, high reliability and so on.

Performance characteristics:

High density flushing joints filter sets

Flush seam along the pipe axis direction, used straight seam welding; unique flush joints of spiral distribution, with spiral welding form, increase the filter strength. When the local external extrusion, compression parts under the external force, reducing or closing the gap, ensure the reliability of sand. Using precision piercing technology, stainless steel seam filter slot opening in the side down, reduce sands hedge crack screen washed out a direct role. Working range of flush seam gap between 0.20mm-0.7mm. Flush seam gap uniformity guarantees within the scope of machining error in 0.015mm, guarantee its filtering accuracy requirements. High density punching techniques, effective opening joint length is 3-5 times the normal slotted pipe, 2-3 times the normal punching slot screen.

Bore hole for Center unique spiral pipe

High density red sewing Center of screen tube with standard oil, sleeving, Center tube screw holes, holes in the pipe cross section area reduction, ensure the pipes on the basis of the whole area of exceeding flowing and to enable the Centre pipe strength to maximize retention. Formation sand is blocked outside the punching slot screen, formation of oil, gas or water rush seam gap, and then after drilling holes into the sieve tube. Ways to reach the sand.

Excellent corrosion resistance

Central tube with API standard casing or tubing, filter using 304 stainless steel material of high density flushing joint.

Containing H2S, CO2, particular requirements for high Cl-wells, pipe corrosion-resistant casing or tubing may be used. Screen resistance to acid, alkali and salt corrosion.

Product scope

Screen can be used for straight shaft, shaft, well completion and open hole completion of horizontal well casing of all kinds of oil, gas and water wells, can be used alone as a sand control pipe string can also be used with filling.
