7 Reasons to use our Cascreen Borecasing & Screens.

This glue takes forever to dry.

1. No waiting time for glue to dry.
2. Full strength of thread is immediately.
3. A very small strength loss in the threaded joint.
4. As there is no shoulder there is nothing to get caught on if needed to pull the casing string back out.
5. Light weight easy to handle, saving time by not using heavy lifting equipment.
6. very cost effective.
7. Non corrosive.
8. Save freight cost when shipping.
9. A smaller hole can be drilled.
10. Lower drilling cost is obtained by using a smaller hammer or drill head.
11. Uses less drilling consumables therefore lowering cost and maintenance time.

PVC bore casing is used  in the following and other areas successfully over a long period of time.

• Water Bores-  Irrigation
• Monitoring wells.
• Drainage.
• Dewatering.
• Leachate collection.
• Soil Vapor extraction.

There are many benefits of using PVC SWJ pressure pipes, it has been the material that many have chosen when building and designing pipeline systems and bores.

The reasons for using our PVC pipes are

• Light weight.
• Manufactured to AS1477.
• Only Virgin Material used.
• All pipes used for Bore casing are UPVC.
• Corrosion resistant.
• Chemical resistant  ( see chart).
• Can be cut on the spot and rejoined immediately no special tools.
• Gluing agent readily available.
• Repair time nearly immediately
• Low friction drag.
• Material strength.
• Ease of Installation

Our threaded casing is machined on special designed machines to ensure quality, production and the perfect thread strength for your application.

Why would  you use threaded screen  instead of swj?
1: Lower cost saving you money compared to a stainless screen.
2: The pipe is flush threaded so there are no protrusions or blockages when  gravel packing the screen down the well.
3:  Readily available.
4: Designed to suit your application.

These have been designed as an alternative to  an Johnson Screen’s Stainless wedge screen, our screens are used when a lower yield is required in a water bore. One of the main uses is in ground water monitoring wells and dewatering. They can be slotted in many different patterns and standards. If you cannot see what you need below the please contact us and we will help you.

These lifting heads are made to help you install your Pvc casing and screen safely and correctly. They are designed to connect them to a sling, screwed into the casing or screen being installed and lifted in the air by a crane and placed over the last installed pipe and then screwed together, the clamp is loosened and the pipe is then lowered down to the next level.
We can also manufacture these in other materials other than PVC and we can manufacture then to suit your requirement. The STD PVC lifting head is the cheapest and will do your job successfully.

These are used to ensure that the casing and screens are centralized in the bore hole drilled, some of the reasons being is that when  using the screen with a gravel pack the gravel pack needs to be evenly walled around the screen to ensure an efficient well  is developed. Also when grouting the drill pipe string into the drilled borehole a even thickness of grouting is obtained.

With the need to eliminate wavering or centralized bore casing when a bailer or probe is to be used inside the casing a centralizer will eliminate this an ensure that the equipment will go down inside the casing without getting caught, as this equipment is sometimes expensive  we do not want to get this stuck down the hole. Our centralizers will avoid this problem.

We can also manufacture these in many different sizes and materials to suit your needs.

These are specially made by DEPS  to connect a Johnson stainless screen to our threaded PVC casing.

These are manufactured to suit your special requirement, these can be in ABS or poly depending on your needs. By using these joiners a large cost saving is obtained as if these joiners where made from solid stainless material specially in the large sizes would cost a incredible lot of money. They are manufactured using the same material as the casing, and then a tube of stainless is rolled to slide inside the pvc casing and a special lock is welded on so the stainless pipe cannot pull through, Therefore the screen is securely held in place by our joiner.

Rib screen was developed specially for the injection and extraction wells in Uranium mines.

The idea was to increase open area of the screen to maximize flow and minimize the impact on the aquifer zone. This type of screen increases the permeability

A close up of a rib-screen screen , this is to show where the horizontal slots cut through the vertical rib slotting.

The vertical slots also increase the open area to the aquifer on the OD of the pipe.
