Well screen(water filter) |
The continuous-slot well screen is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry. The Continuous-Slot Well Screen is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. Slot opening for continuous-slot screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burrs and cuttings. Each slot opening between adjacent wires is V-shaped, from the special shape of wire used to form the screen surface. The V-shaped openings designed to be non-clogging, are narrowest at the outer face and widen inwardly; they allow |
1. Production process continuity: V-shaped profile wires creating slots which enlarge inwardly and therefore avoid clogging and minimize downtime.2. Low maintenance costs: Separation at the screen surface which can easily cleaned by scraping or back washing.3. Maximum process output: Precise and continuous slot openings resulting in accurate separation without loss off media.4. Low operational costs: Large open area with an effective flow, high yield and a low pressure drop (dP)5. Long live: Welded at each intersection creating a strong and durable screen. 6. Reduced installation costs: supporting constructions eliminating costly support media and enabling a maximum flexibility in the design of components.7. Chemical and thermal resistant: A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures. Each slot opening between adjacent wires is V-shaped, resulting from the special shape of the wire used to form the screen surface. The V-shaped openings, designed to be non-clogging, are narrowest at the outer face and widen inwardly. Continuous-slot screens provide more intake area per unit area of screen surface than any other type. For any given slot size, this type of screen has maximum open area. |
1. API 5CT Slotted pipe
Character: Oil filter screen pipe are used for oil exploring. The rigid construction and high quality of materials make possible a product that lasts longer and requires less maintenance. We also can offer galvanized ones to prolong the operational life.
Meanwhile, our company can offer a whole set of service, such as the related process, the solution of the related technology and so on. And we can make products according to the clients real conditions.
If you are interested in our product, please contact us, and for more information.Features:
1.A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone..
2.Filter area is big, flow resistance is small, high producing oil rate
A uniform and efficient well development due to the continuous slot opening..
3.Our product have good character of anti-acid, anti-alkali and anti-corrosion, it can adapt to the oil well’s special demand. the crack won’t become bigger because of corrosion. it has good stability
4.They have the features of easy backwashing, durable in use, safety and reliability as well as low comprehensive cost
