Product Description

 

Slotted Casing

Slotted casing pipe is a method of cutting multiple longitudinal or spiral straight-arranged and staggered slits of certain specifications on oil casing or tubing in various ways. It is made by using a special ultra-thin cutting sheet and beam cutting, with a slit width (0.2-0.5mm). The cross-sections of the seams are rectangular, trapezoidal (trapezoid angle is 3-8 degrees) and special shapes (round holes), etc., which can ensure the permeability of 0.5%-10%. The layout of the seams can be processed according to user requirements.

 

Product features of slotted casing:

1. Slotted casing is suitable for sand control in sand wells with a sand particle size greater than 0.3mm.

2. The edge of the slotted casing has good verticality, the cutting edge is smooth and burr-free, and the cutting seams are even.

3. The flow area is large, the 27/8" screen tube has 300 slits/1.5m, which is 2.4 times larger than the flow area of oil pipes of the same specification.

4. The overall performance stabilization treatment improves the corrosion resistance and performance of the slotted casing, which can extend its underground working life.

5. The slotted casing is made of J55 or N80 petroleum casing body, which has good strength and is not easy to deform.

6. The inner diameter of the slotted casing is large, making it easy to configure the pipe string.

 

Slotted casing have straight and trapezoidal grooves with a minimum slot width of 0.012 inches and a maximum slot width of 0.25 inches.

Slotting patterns of Slotted Casing

Three distinct slot layouts have been created to accommodate distinct traits (shown below). In comparison to staggered and straight slot patterns, the gang slot design significantly improves the liner's resistance to lateral buckling and collapse stresses.

 

Staggered Slotted Casing	Gang Slotted Casing	Straight Slotted Casing
Staggered slots are evenly distributed around the circumference with an offset	Gang slots are made up of many slots that are dispersed around the perimeter	Straight slotted liner features slot columns spaced evenly around the circumference without offset

 

 

Slot types of Slotted Casing

- Straight Slots

This slot type is cut perpendicular to the liner and has the same diameter from the inside to the outside of the wall. While straight slots are less expensive to build, they are less effective in containing sand than keystone slots.

 

- Keystone Slots
Keystone slots, or tapered slots, are cut at a little angle and are larger on the inside than on the outside, ensuring that any particle entering the slot can pass freely without clogging it.
 

While keystone slots are more expensive to manufacture than straight slots, they eliminate the danger of production losses caused by filled liner slots.

Q:How can I place order? 
A: You can contact us by email or social media like WhatsApp on the order detail or place order on line. 

Q:How about the payment?
A: For new clients, advance payment(30%-100% of total amount) is required, the balance need to be paid before the delivery after your inspection.

Q:How can I pay you?
A: By T/T (Telegraphic Transfer) or L/C (Letter of Credit). After you receive the PI, you can make the payment through your bank as per the terms mentioned in PI.

Q: What's the order procedure? 
A: First we discuss order details, production details by email ,TM or other social media; then we issue you an PI for your confirmation. You will be requested to make full payment or deposit before we go into production.After we get the deposit, we start to process the order. Depending on the products you order, we usually a couple of days or even moths to complete production if we don't have the items in stock. Before production has been finished, we will contact you for shipment details, and the balance payment. After payment has been settled, we shall arrange the shipment for you. 

Q: How do you deal with  defective products received by the clients? 
A:  If there are some defective items, we usually credit to our customer or replace them in next shipment.
