Products name: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. Saigao 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 nonclogging, 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 opeings, designed to be nonclogging, 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.

Pipe Base Screen
Our pipe base screens are manufactured with strict quality standards to be at par with international standards. The screen jackets are manufactured by spirally wounding narrow faced Vee-Wire around a cage of longitudinal support rods. Each intersection point of these wires is fusion welded. These jackets are then mounted over seamless pipe(API Casing, tubing) which is perforated as per international standards to ensure flow performance, and then both ends of jacket are welded on to the seamless pipe.
Feature
1.High flow capacity. The jacket is made of vee wire well screen this allow more water or oil to enter at much lesser frictional head loss and the efficiency of well is improved appreciably.
2.Perfect integral strength and strong anti-deformation ability The internal part of filtration jacket is supported by base pipe and the outer protective shroud can be fixed outside the filtration jacket if necessary. The integral strength of base pipe with drilled holes is merely 2~3% less than standard casing or tubing. So it can withstand compression deformation from stratum with sufficient integral strength. Even if local deformation occurs, the gap of compressed part will not be enlarged. It has been proved to be highly reliable on sand control.
3.More choice: The screen jacket material can be stainless steel or low carbon steel,it is can as per your requirement.
4.Slot with high density, low flow resistance .Slot density are 3~5 times as traditional slotted screen, with low flow resistance. It is conducive to increase production of oil or gas.
5.Good manufacturability makes high efficiency, low cost, and large-scale production achievable.
