we are offering slotted liner – customized slot width & various slot patterns. slotted liner or standalone screen is a popular sand control screen in long horizontal completions and low productivity wells. precision slotted liners are manufactured by cnc controlled slotting machines or laser machine. all slots are de-burred, cleaned and drift tested according to api standards. base pipe are per api casing or tubing specification with diameters from 1.5 inch to 18 inch. pipe lengths of any diameter are available. slot size slot size including slot width and length is customized to suit customer’s requirement. for straight or keystone slots, minimum slot width is 0.012 inch and maximum slot width would be 0.25 inch. 1.5 inch long 2.0 to 2.5 inch long 2.5 inch long 0.012 inch wide 0.024 inch wide 0.078 inch wide 0.015 inch wide 0.025 inch wide 0.125 inch wide 0.016 inch wide 0.038 inch wide 0.250 inch wide 0.018 inch wide 0.048 inch wide - - 0.058 inch wide - slotting pattern slots in straight and staggered arrangement slot pattern a: refers to single staggered slots. b: refers to straight slots. c: refers to multiple staggered slots. slot shape slot liner with straight slot & keystone slot slot shape straight slot straight slot has straight sides with equal width through the wall of the casing. it is normally used in consolidated formations or when slots of 0.030” or wider are specified. pros: higher resistance to wear and more economical than keystone. cons: the possibility of clogging is higher than keystone slot. keystone slot keystone slot is like a reversed “v” with narrower spacing at the liner surface and wider spacing in the inside casing wall. this shape allows for sand grains to bridge across the opening and ensures all the particles that enter into the hole will completely go through the wall.

we are offering perforated liner – base pipe for sand control screens. perforated liner is manufactured by multi spindle drill presses. it is deburred internally and externally, and every hole is visually inspected to make sure all burrs are cleaned up according to api standards. perforated liner with various hole spaces perforated casing perforated casing is often used as base pipe for wire wrapped screen, pre packed wire wrapped screen & metal mesh screen. hose sizes, patterns and pitches (hose spacing) can be customized. hole sizes standard hole sizes: 9.5mm, 13mm, 14mm, 16mm, 19mm and 25mm. other hole diameters are available. hole pattern holes can be staggered or in straight line as the following pictures from fig 1 to fig 3. holes are commonly arranged in spiral shape. straight line is possible. pitches pitches can be 1”, 2”, 3”, 4”, 6” or 12”. 2”, 3” and 6” are recommended. perforated liner in different pitches and shape perforated liner hole arrangement how to work out open area of perforated liner? open area will influence production and sand filtration. it is determined by hole diameter, the number of holes and the diameter of the liner. the following formula will tell you how to calculate the open area. n = n = cfrac{12×d×c} {25×d2} n refers to the number of holes per foot. d refers to the outside diameter of the liner in inches. c refers to the required open area (percent of surface area). d refers to the diameter of hole in inches. perforated liner api pipe size (inch) od pipe (mm) id pipe sch40 (mm) id pipe sch80 (mm) od coupling (mm) holes per foot standard pattern 2 60.33 52.51 49.25 73.0 84 2 78 73.03 62.71 59.01 88.9 96 3 12 88.90 77.92 73.66 108.0 108 4 12 114.30 102.26 97.18 127.0 168 5 12 141.30 128.20 131.77 153.7 192 6 58 168.30 154.08 146.36 187.7 204 8 58 219.08 202.72 193.68 244.5 240

Bridge slotted screen is normally used in water wells for sand controlling. It is manufactured from precision punched quality metal sheet including st37-2 or stainless steel 304316l. The slots are punched in a flat sheet and at the same time the sheet is rolled into a tube and welded. Slots are arranged in staggered arrangement to reduce negative effect on the screen’s strength. Bridge sand screen is a combination of superior weld strength and accurate slots. The slot openings are not completely punched out to increase mechanical strength. The slot of bridge screen is like a gravel pack retainer allowing the odd of blocking is very low. The prerequisite of bridge screen is the right gravel pack design.

we are offering pipe based wire wrapped screen. wire wrapped screen consists of a wire-wrapped jacket and a perforated pipe. keystone shaped wire are helically wrapped around the vertical ribs and each point of contact is welded. this special shaped wire is designed for decreasing the chances of sand plugging the screen, self-cleaning action and reducing flow friction. the diameter and number of ribs depends on the strength and size the screen. the more the number is, the stronger the screen is. wrapping should be accurately controlled to form uniform & precise gauge for reliability. pipe based sand screen is used in stand-alone completions with well sorted formulations or in combination with gravel packed completions. it provides superior strength & accurate slot openings. compared with slotted liner, its larger inflow area maximizes the production. wire wrapped screen is wedge wire around perforated pipe v wire wrapped sand screen product description: material for wire: stainless steel 316l or nickel alloy 825; material for base pipe: upon request; wire width: 0.090 in.
