Product Description:

Slotted casing pipes are mainly used for water and oil reservations where there is not much sand. Its function is to prevent rock fragments from falling into the well bore. It works by allowing a certain size of sand to carry crude oil through the surface, but leaving a larger size of sand to be plugged on the outside to form a sand bridge, so as to achieve the purpose of sand control. Slotted casing pipes are widely used in oil filters, and they can filter out 99% of sand, greatly reducing the maintenance rate of the pipe, and also improving the strength, integrity, and stability of the pipe against sand ingress. The slotted tube is produced by laser cutting technology, with high slotting accuracy, good edge verticality, smooth trimming without burrs, etc.

Advantages:

Slotted casing pipe has several advantages over other types of casing pipe.

1. Durable and withstand high pressure and temperatures.

2. Easy to install and can be adapted to fit any size well bore.

3. Reduce the amount of time and money spent on well repairs, reduce the pressure on the formation and prevent sand and other debris from entering and damaging the pump.

Technical Parameters:

Slotted liner patterns illustration:

Three slot patterns are designed for different characteristics (shown below). Compared to staggered and straight slot patterns, gang slot pattern has superiorities over installation torque-loading capacity and substantially improves the liner’s resistance to lateral bucking and collapse pressures.

Slotted Liner Patterns
Staggered Slotted Liner	Gang Slotted Liner	Straight slotted liner
Staggered slots features alternate slot evenly spaced around the circumference with offset.	Gang slots feature multiple slots evenly spaced around circumference in a staggered pattern.	Straight slotted liner features slot columns spaced evenly around the circumference without offset.

Applications:

It is commonly used in oil and gas wells, water wells, and geothermal wells. It is also used in tunnels and underground chambers, such as those used for storing hazardous materials or for mining operations. Slotted casing pipe can even be used in agricultural applications, such as for irrigation or drainage.
