Posted By admin On 26/07/222015 Casing Reference Tables C–112JANUARY 2015/WorldOil.com D d t D c Hunting TKC 4040 RTC is spe- cially designed as a low-stress, multi-cycle fracture string. Casing Our Flush Joint Casing is available in multiple grades to match your application. We offer lower-grade steel for shallow precollaring, where the casing is left in place, and high-strength alloy steel casing for deep and difficult conditions. Flush Thread Screen and Casing - PVC Schedule 40 and Associated Caps, Plugs, Points and O-rings. 10 - 17 Flush Thread Screen and Casing - PVC Schedule 80 and Associated Caps, Plugs, Points and O-rings. True Flush Joint connections are designed to ensure that the connections’ outside diameter and inside diameter are the same as the original tubular. Used predominantly in special clearance applications like liners, the flush joint connection exhibits strengths of.
Volant’s rigid-steel centralizers provide positive standoff, mitigate buckling and facilitate rotation using crimp-on technology to overcome friction and other running challenges. This leads to improved run-ability of your casing string by saving time on the run. The sturdy, helical ribs provide positive stand-off and flow areas for solids removal, improved mud flow and a high-quality cement job. Combining our durable centralizers with an optimized placement strategy provides the best opportunity to quickly and efficiently reach target depth without sacrificing the long-term integrity of your well.
Our patented and proprietary hydroforming technology allows precision forming into a variety of custom shapes and profiles for drilling, reaming and completing critically-challenging, high-profile wells. Full control over HydroFORM® process to design and manufacture custom centralizers for special or unique applications.

Features & Benefits- One-piece, uni-body construction reduces the risk of sticking or unexpected hang-ups and there are no components to break or fail downhole.
- Robust durable steel design ensures centralizer stays intact under the most extreme running conditions.
- Smooth geometry improves running efficiencies through reduced torque and drag.
- Smooth ribbed body allows for improved hydraulic flow for fluids and solids removal.
- Helical rib design provides maximum standoff, helping to bridge possible key seating which can occur during drilling or rotating operations.
- Helical rib design offers rotational flow in the annulus to improve mud removal and cement placement for a more uniform cement distribution and bond.
- Straight rib design available for low clearance or tight hole applications to still provide optimal standoff.
- Ability to hard-face centralizers for increased wear resistance where required.

Yes2Yes*There are several cases where the use of centralizers and set screw stop collars applied to flush or semi-flush joint casings has led to the centralizers and the stop collars piling up over the length of the string. Crimping on of stop collars for a non-rotating application or crimping on of the centralizer itself for a rotating application can mitigate this issue.
1. Application specific
2. For use with stop collars only
- Applications Engineering support to optimize placement of centralizer to improve run-ability.
- Floating centralizers move freely, axially and rotationally on casing, allowing them to overcome irregularities in the wellbore during run-in.
- Crimped centralizers rotate with casing to give added durability to your string.
- Hardfaced centralizers provide extra wear resistance to get through tougher formations.

DPI Casing is available in multiple grades:
We use Premium alloy steel when the casing is being re-used on an everyday basis and is subject to both drilling and driving applications. Where operations entail less abuse, we can suggest casing with slightly lower strength specifications.
Example:
Pre-collaring a shallow bore hole, and expecting to leave the casing in place – we will match this application with a steel that will do the job and provide you value.
We can also recommend a thread profile and advise you of the benefits and limitations of each, “W” (Square thread) or WJ (Tapered thread), that best matches your product use.
All Casing is threaded in one of our CNC Machining Centers. Each thread is checked and rechecked with our DCDMA Certified Gages – always part of our Quality Assurance Program.
