Screen Tube

Screen tube, called screen pipe, oil well screen, sand control slot screen, We Have two kinds manufacturing method.

Materials: 304 302 304L 316 316L stainless steel wire, can be made according to the customers'  requirement.

Diameter: 1-40inch(27-1000mm)

Slot: 0.05-6mm

Length: up to 6000mm

End connection: welded rings or threaded male and female coupling.

Flow: from inside to outside, or from outside to inside

Characteristics: The welded stainless steel water well screen is made up of rods and warp. The rod can be round wire, triangular wire or trapezoid wire. The warp is triangular wire (V-shaped wire). Water well screens have a structure and high open area, as well as accurate slot dimension. At the same time, water well screen have heat-resisting, anti-corrosive, good machine capability, last long, safety and reliability and so on characteristics. It can be used in many kinds of medium filtering.

Advantage:

• Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells, avoids clogging and ensures an uninterrupted flow.Abundant water shall reduce the water level’s down, thus to save energy consumption
• Screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
• Reduce the abrasion of the pump.Under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than any other filtration apparatus, which will avoid sand’s entering into screen because of high pressure, thus reduce the abrasion of the pump.
• Extend the life span of wells.Comparatively, groundwater’s entering into screen with higher open area is much easier than the entering into lower open area screen. The slow water flow shall extend the life span of wells.

Uses: The strainer is a kind of filtered water tubing with the perforation .it can use with the deep well pump, dive the water pump, also may use in the water-treating equipment, the environmental protection, the sea water transforms into the industrial water and life use water desalination treatment, running water treatment, water softening treatment, the petroleum industry: The petroleum product terminal filters and the chemical acid, the alkali liquid filters, the ethyl alcohol and so on the organic solution recycling filters.
