Slotted Liner Well Casing Pipes
Product Description
Slotted Liner Well Casing Pipes
Production Information:
Product Feature:
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 backwashing, durable in use, safety and reliability as well as low comprehensive cost.
This laser slotted screen pipe used for petroleum. It can prevent 99% sand, decrease 80% of oil well heavy repair and increase the oil well's strength, integrality and stability of keeping off sand, although its structure is simple. It's very effective. It has small cuts of 0.10—0.5mm in the tube wall.
