We are Huashi Science&Technology Development Co., Ltd. of China University of Petroleum based in Dongying , China. We are member of Tradekey.com since July, 2008. Our business is related to Industrial Machinery industry and we specifically deal in Screen pipe. Please find our product details below: The precision slotted screen liner The precision slotted screen liner with compound sand control is consisted of base pipe, gravel-packed and jacket ***** precision tube with compound and control is suitable especially for the siltstone geology:it can be extensively applied for well completion or sand control in the horizontal well, side-tracked well and branch well. There are two kinds of base pipe:with slots and with holes. slotted screen pipe Every slot of slotted screen pipe with compound cavity cutted bu laser from outside to inside of the liner consists of trapezoidal slot similar to rectangle with outside narrow and inside wide, transitional arc and another trapezoidal slot with one large ***** outside trapezidal slot is similar to rectanglewhose thickness is 2~***** angle of outside trapezoidal slot is very small, which weakens the fretting corrosion ratio of oil with sand and then prolongs the sevice life of screen liner.Because of the large angle of inside trapezoidal slot, the flow resistance of crude oil caused by the slot can be greatly reduced, which improves the efficiency of oil production.Slotted screen liner has advantage in self-cleaning It is cutted by plasma.When the plasma blaze with high frequency and temperature is processing the screen liner, the water-base compound operating fliud produces electroytic dissociation thermal decompsing reactivity, whose production reacts with external metal material of screen ***** surface of screen liner is simultaneously affected both the heating by the plasma blaze with high frequency and temperature and the cooling by the operating ***** there generates a 0.1~0.2mm hardening and antiseptic layer on the processed surface of screen liner which can effectively advance the abrasion resistance and inoxidizability of the slot. Double layer screen pipe with gravel-packed Double layer screen pipe with gravel-packed is consisted of base pipe, gravel-packed and jacket ***** precision tube with compound and control is suitable especially for the siltstone geology:it can be extensively applied for well completion or sand control in the horizontal well, side-tracked well and branch well.
