Slotted Casing/Pipes Material:stainless steel, carbon steel, API material, J55/K55,N80,L80,P110 The slotted liner is mainly used to the water and oil reservation layer without much sand. It's function is to prevent rock bits from dropping into the well bore.
The shape of the casing section is round, in large diameter pipes and is inserted into the oil well, fixed with cement to protect other equipment that is mostly made of iron and steel. The oil well must be designed to withstand the force different from the external power, such as crushing, explosion, stress and chemical corruption. API 5CT casing pipe is used to support the oil and ERW Slotted Steel Pipe - ERW Slotted Steel Pipes ERW Slotted Steel Pipe. Our company is engaged in manufacturing and exporting of wide array of Slotted Pipe/Screen Pipes.These are manufactured from quality approved steel by semi automatic slotting machines and carry features such as high tensile strength, dimensionally accurate and long operational life.
CASING AND TUBING. Casing and tubing strings are the main parts of the well construction. All wells drilled for the purpose of oil or gas production (or injecting materials into underground formations) must be cased with material with sufficient strength and functionality.Oil country tubular goods (OCTG) is a family of seamless rolled products consisting of drill pipe, casing Oil Well Construction:Casing and Tubing - Analyzing MetalsCasing is a series of steel pipes that are run into a drilled oil well to stabilize the well, keep contaminants and water out of the oil stream, and prevent oil from leaching into the groundwater. Casing is installed in layers, in sections of decreasing diameter that are joined together to form casing
Cresline PVC Well Casing Pipe is produced using PVC 1120 polyvinyl chloride material to meet or exceed ASTM F480 standards and is NSF-approved for well casing use. SDR-21, SDR-26, and Schedule 40 sizes are NSF-approved for drinking water use. Perforated Casing Pipes/Tubes for Water Well Screen Sand Slotted/perforated pipes and tubes are common casing layer for pipe-core wire wrapped well screens. The perforated casing tube has round holes uniformly distributed for smooth flow of the liquid. It is actually a supporting pipe for sand control system in drilling oil or water wells. The metals are mostly stainless or mild steel. How it Works:Perforated pipe or punched tubing is
Home > Product > Oil Well Screens > Slotted Casing Slotted Casings Slotted casings are widely used for oil filters, they can filter out 99% of the sand, which greatly reduces the maintenance rate of the tube, and also improve the tubes strength, integrality and stability of keeping off the sand. Slotted Liner Manufacturer SAIGAOSlotted Liner. The slotted pipe (slotted casing) is machined by J55 or N80 oil casing body, which has high strength and is not easy to be deformed. The edge of the slit is perpendicular, the trimming is smooth, no burr, and the slit is uniform. The flow area is large, and the 27/8 screen tube is 300 strips.
The slotted tube (slotted casing) is divided into two categories:oil liner pipe and water collecting liner pipe, which are respectively made of various steel grade pipes. It meets the requirements of API Spec 5CT Slotted screens are cut into a number of longitudinal or spiral straight-line slits of a certain size in a variety of ways on oil Slotted Pipes - well screen|water well screen|wedge wire Slotted pipe are used for oil and gas wells. Steel casing pipes and tubing are applied to furnishing and installing cased tunnels, where they indicate to pass other utilities or obstructions without open excavation. Steel casing pipes and tube have smooth wall and a minimum yield strength of 35,000 psi.
Jun 29, 2015 · Slotted liners. Slotted liners are made from tubulars by saw-cutting slot configurations, as shown in Fig. 2. Slot widths are often referred to in terms of gauge. Slot or screen gauge is simply the width of the opening in inches multiplied by 1,000. For instance, a 12-gauge screen has openings of 0.012 in. Valley Perforating SlottingOIL WELL LINERS/WATER WELL CASING Straight and Under-cut Slots Sizes:1" through 22" STRAIGHT MILL SLOTTING. This was the first type of slot manufactured. It has straight sides with equal width throughout the wall of the casing. This type of slot is more readily plugged by formation sand than keystone slots.

Steel Casing pipe Stabilize the wellbore. Steel casing pipe is used to line the borehole that is being dug into the ground to get oil. Just like the drill pipe, the steel pipe casing is also subject to axial tension. This is the large diameter pipe inserted into a liner Oilfield Glossary1. n. [Drilling] A casing string that does not extend to the top of the wellbore, but instead is anchored or suspended from inside the bottom of the previous casing string. There is no difference between the casing joints themselves. The advantage to the well designer of a liner is a substantial savings in steel, and therefore capital costs.
Oil well drilling slotted liner/perforated casing pipe. The slotted liner is mainly used to the water and oil reservation layer without much sand.Its function is to prevent the rock bits dropping into the well bore.The working principle is allowing the certain size sand coming through the surface with crude oil but keeping the bigger size sand being stopper outside to form sand
