Laser Slotted Casing Pipes 
Description:
Our factory is specialized in producing 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 veryeffective. It hassmall cuts of 0.10—0.5mm in the tube wall.
Also now our factory are planning to establish the biggest laser cutting slotted pipe in Asia,welcome any customers from any countries to come to China and establish our nice relationship.

12. Also please take your our sample drawings below.any other demands,you can tell us,we will be glad to give our opinions for you.
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 backwashing, durable in use,safety and reliability as well as low comprehensive cost.
Inspection:
BV,SGS,ROHS etc.
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 customers’demands.
