Steel Repair Sleeves
A 71-year Legacy of Reliable Repair Sleeve Solutions
Allan Edwards has been providing pipeline repair sleeve solutions since 1950. With 71 years of service in the sleeve business, it’s become personal for us, and we make it a point to offer the right sleeve solution, at the right time, in the right way for our customers. Our wide portfolio of repair sleeve solutions is manufactured fully in-house at our shop yard in Tulsa, Oklahoma. Our goal is simple: to provide our customers with preventative maintenance and peace of mind.
Our Sleeve Story
We put in the work, and our unparalleled sleeve testing confirms that. Read our story here:
What Sets Our Sleeves Apart?
Extensive Validation Testing Through Joint Industry Program (JIP) Participation
There are many repair sleeve manufacturers out there that claim their sleeves are effective. But do they have the data to back it?
The CFR 192 and 195 regulations are the only governing authority over the use of steel sleeves as a pipeline repair method. Interpretation of these codes varies regarding whether sleeves must be comprised only of pre-tested pipe or whether sleeves manufactured from rolled plate are an equally valid repair option. Because we manufacture our sleeves from rolled plate at Allan Edwards, we decided to undergo a rigorous testing program never attempted by any other sleeve manufacturer, to demonstrate our sleeve effectiveness.
Why? Because the stakes are high in this industry, and we knew the importance of reducing uncertainty for our customers though providing evidence of our sleeve effectiveness.
Sleeve Study JIP: Mr. Precht Goes to Washington
From 2017-2019, Allan Edwards, along with five pipeline operators, participated in a Joint Industry Program (JIP) to validate the use and performance of repair sleeves manufactured from rolled plate compared to those formed from pre-tested pipe. Before embarking on this study, our senior sales representative, Tommy Precht, along with Dr. Chris Alexander, P.E., of ADV Integrity, visited to the PHMSA offices in Washington, D.C. to gain their perspective on conducting such a study. As cited in our report, “During a meeting with PHMSA representatives…the regulators were pleased to hear this study was being conducted. With the current regulatory environment being moved towards ‘performance, rather than prescriptive’ regulations, the full‐scale testing approach used in this study [was] encouraged by regulators.”
JIP Study Results:
Throughout the course of this full-scale testing program, “the study evaluated the reinforcement of both corrosion and plain dents that were pressure cycled to failure. A total of six samples were tested in this program, which included two samples with unreinforced defects that served as baseline data points.” The program successfully demonstrated the durability and effectiveness of manufactured sleeves as an appropriate repair solution for the reinforcement of corrosion and dent features, increasing their fatigue lives to at least 424 years.

Official Steel Sleeve Certificate of Quality
Following the conclusion of the steel repair sleeves JIP, Allan Edwards was approached by another pipeline operator interested in an even more comprehensive testing program for Allan Edwards sleeves, featuring additional defects and higher fatigue stress levels. “This burst test successfully demonstrated that the Type‐B repair sleeve manufactured and supplied by Allan Edwards can reinforce a leaking defect past the maximum allowable design pressure of the carrier pipe with a considerable safety margin.” On July 1st, 2019, after testing completion, a Certificate of Steel Sleeve Quality was drafted and signed by Dr. Chris Alexander, P.E., of ADV Integrity, a prominent figure in the pipeline industry. This document validated the superior performance of Allan Edwards sleeves.
Available Sleeve Types
Half Sole Repair Sleeves
- Tight fitting sleeve that provides reinforcement for damage or anomalies on pipelines
Fabricated Weld Sleeves
- Custom-made sleeve, manufactured to meet exact specifications for a custom fit over flanges, hot tap fittings and a variety of pipeline jewelry
Girth Weld Sleeves
- Used to reinforce a welded pipe joint
Low Profile Pumpkins
- Used on pipelines with screw collars and dresser couplings. Available in a design suited for easy installation
Copies of material test reports are kept on file and used to verify heat numbers prior to cutting material in the first step of manufacturing.
Marking and Shipping
Each piece of the half sole sleeve is clearly marked with size, wall thickness, grade of steel plate, heat number, Allan Edwards job number and customer purchase order number.
Mechanical Properties and Testing
Mill test reports are furnished on all materials. Independent testing may be performed to check the hardness on stock plate. Additional independent testing available includes destructive, magnetic particle, liquid penetrate, ultrasonic and radiographic.
Additional Helpful Information
- Half sole sleeves are formed by rolling or die-forming without the use of heat treating.
- Longitudinal edges of half sole sleeves can be beveled for welding, if requested.
- Half sole ends have sheared square edges for fillet welding unless square-end bevel is requested.
Milling of Half Sole for Backing Strips
Half Soles can be milled on the inside longitudinal edges for the backing strips.
Backing strips are hot-rolled commercial carbon steel sheets and strips of commercial quality.
Casing Extension Package
When a pipeline runs beneath a crossing such as a roadway, driveway or railroad, it must be fitted with a casing to provide additional compression to the pipe. This compression helps the pipeline cope with increased pressure put on the pipe when heavy vehicles or machinery pass over it. Allan Edwards sleeves make ideal casing extensions when these crossings are widened, since the pipe casing undeath the crossing must be widened in tandem with the crossing. We simplify the purchasing process for our customers by ensuring all casing extension components are available as a bundle when needed. This eliminates the need for our customers to coordinate with multiple vendors to source the right materials for a job. Delivery dates and locations are simplified as well: all materials are shipped together to one location. Our customers to come to one place to find all these items:
- Half Sole Casing Extensions
- End Links / Link Seals
Simplify your logistics so you can get the job done with minimal hassle. We are here to help.
Our Quality Control Guarantee: Examination
We stand behind the work we do. All half sole repair sleeves are thoroughly inspected for defects before shipment. All dimensions, including end and side preparation, are measured and verified, and a visual inspection is performed. Any pipe repair sleeve that does not meet the requirements for dimensional tolerance and visual inspection is rejected.

Manual Pipe Jack for Sleeve Installation –
a convenient, cost-effective solution to simplify your job.
Allan Edwards custom-made manual pipe jacks provide a simple, solution-based approach for the safe installation of Half Sole repair sleeves on steel pipe. By securing the two halves of the sleeve over the affected pipe section as they are welded, the manual pipe jack enables a stable and precise fit.
Features & Advantages
- Available options for wide range of pipe diameters
- One jack fits multiple pipe sizes
- Comes with cottered roller chain to ensure uniform application of pressure
- Strong, durable design
- Long-lasting & dependable
- This is not a multipurpose jack. Its only application is for Half Sole repair sleeves.
- A 2-5/16” open end or box end wrench is required to operate pipe jack. Wrench is not included with product.
- 18” or larger Half Sole sleeves, depending on length & wall thickness, may require 3-4 jacks.
