Hebei Hengying Wire Cloth Co.,Ltd. has developed together with the relevant scientific research organizations series filter products for petroleum chemical filtration: Oil sand control screen (anti-sand filter blocks), spiral welded stainless steel filter tube (spiral welded pipe), straight seam welded stainless steel filter tubes, well received by the oil field customers.
Product performance and features:
Spiral Welded Pipe
Perforated seam is welded in straight line; with unique spiral distribution formed by spiral welding and greater filter strength. When squeezed in some parts from external, under outside pressure, the forced part will have reduced or closed gap and ensures the reliability of sand control. Made with sophisticated technology, stainless steel filter glove has openings in the side with reduced direct corrosion to the perforated welded sand pipe. Seam gap in the processing ranges between 20 mm-0.7mm. The uniform opening ensures the processing difference is within the error scope allowed - 0.015 mm, also ensures the accuracy of its filter requirements. Using high precision perforating technology, the effective slotting length is the three to five times of common cut seam tube and two to three times of common perforated seam tubes.
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.
