Product Details

Product Description

Features:

1. A continuous slot opening which significantly increases the available open area, thus providing

greater access to the water bearing zone.

2. 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.

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 back washing, durable in use,safety and reliability as well as

low comprehensive cost.

Packing:

Generally speaking.the inside is packed by plastic membrane,the outside is packed by non-woven

fabrics,then we bundled them by steel strip.also we can pack them according to customer's demands.
