The PETROSLEEVE® is manufactured in Canada at our manufacturing facility in Nisku, Alberta. It is easily shipped from this location throughout the world.

No. The PETROSLEEVE® is a complete system that includes both the manufactured sleeve component and the engineering and testing component that has proven the EIP installation program required to confirm and validate repair criteria and, ultimately, the post-repair validation.

The PETROSLEEVE® is installed in the USA, Canada, Mexico, Dominican Republic, Australia and in Papua New Guinea.

Over 28,000+ successful installations worldwide.

PETROSLEEVE® installations are made on (but are not limited to) steel pipelines carrying Crude Oil, Natural Gas, Sour Natural Gas, Fresh Water, Fuel Gas, HVP Products (butane, ethylene, propane, pentane, liquid ethane), LVP Products (condensate diesel fuel, gasoline, heating oil, hydrocarbon diluents, kerosene, solvents), Misc. Gases, Misc. Liquids, Oil Well Effluent, Salt Water.

Testing and finite element analysis illustrates that the compressive action of the PETROSLEEVE® extends approximately 2 inches past the edge of the sleeve. Consequently, when the sleeves are installed within 1 1/2 inches of each other, the forces developed by the two sleeves overlap and act to restrain the bare pipe between the two edges. We recommend installing each subsequent PETROSLEEVE® as close as possible to the one previously installed.

Extensive testing on the PETROSLEEVE® technology has been undertaken, including pressure cycling, compression verification, through wall defects, dents, girth weld defects, welds, and crack extension. In addition, FEA analysis in conjunction with strain gauge work has supported sleeve development.

PETROSLEEVE® installations over stress corrosion cracking and corrosion defects were removed after being exposed to extended severe field conditions. When the sleeves were removed, the pipe surface where the epoxy had been sheared by the removal process appeared bright and clean, similar to a newly sandblasted surface.

In most circumstances, there are no pressure limits for PETROSLEEVE® installation and operation. However, based on the severity of the defect being repaired, and in some cases for large diameter repairs, pressure may require reduction during installation to ensure optimal safety conditions

Yes, the PETROSLEEVE® Pipeline Repair System and installation design is a patented process with multiple patents and patents pending.

After a PETROSLEEVE® is installed, any magnetic flux leakage inspection tool will identify the sleeve. Ultrasonic inspection tools will not identity the sleeve, but will identify the repaired defect.

Prior to installing a PETROSLEEVE®, the EIP (Engineering Installation Parameters) software is utilized to determine the sleeve design and installation parameters. The sleeve/pipe/defect assembly is designed to arrest the growth or deterioration of the defect.

Part of the installation procedure is to perform and follow quality control procedures. The information obtained in this process is input into the complimentary EIP (Engineering Installation Parameters) computer software program. The EIP software then calculates the stress level in the steel under the PETROSLEEVE®, and is also able to determine the stress intensity at the crack tip (in the case of a crack or crack-like defects).

The PETROSLEEVE® delivers defect repair for Seam or Pipe Body Cracking, Corrosion, Dents, Mechanical Defects, SCC (Stress Corrosion Cracking), and Arc Burns. Although the failure mechanism varies for each defect type, the following provides a good overview of how the PETROSLEEVE® permanently removes failure mechanisms relative to each defect type: LINK TO DEFECTS

Currently, the PETROSLEEVE® is not recommended for leaking defects, active internal corrosion, or repairs on very sharp and short radius bends.

Significant cyclic pressure testing was performed in an attempt to cause fatigue cracking to extend. After 35,600 severe pressure cycles, no evidence of crack extension was identified.

Because of the compression forces between the PETROSLEEVE® and the pipe, electrical contact exists between the pipe and sleeve. Consequently, the cathodic protection impressed upon the pipeline will protect the sleeve steel.

There is NO maximum length of repair that can be completed by the PETROSLEEVE® within the minor limitations that may exist for this repair technology. The maximum length of a single manufactured PETROSLEEVE® is 36” (914mm), however, multiple sleeves can be added in subsequent fashion to repair virtually any length of defect.

When a defect is longer than a sleeve, multiple sleeves are installed. The sleeve edges are butted to each other; NOT welded together circumferentially.

The PETROSLEEVE® has been installed on many "out of round" pipes. In all cases, the installation method resulted in a compression fit with no installation difficulties with “out of roundness”.

It takes approximately 1 hour to install an average sized PETROSLEEVE®.

When the PETROSLEEVE® Pipeline Repair System is used for a pipe defect, the installation provides additional integrity to the pipe, equivalent to a heavy wall section of pipe. Because the sleeve is composed of steel, the impressed cathodic protection used to protect the pipeline also protects the PETROSLEEVE®. What type of coating is used on the PETROSLEEVE®? Any coating suitable for coating pipe can be used on a PETROSLEEVE®. When selecting an appropriate coating material for final coating, consideration should be given to ensure a proper seal at the sleeve ends and accommodating the profile between the carrier pipe and the PETROSLEEVE®.

Clause 195.416(f), Federal Register, Vol. 64, No. 239, states that a repair method shall repair the pipe "by a method that reliable engineering tests and analysis show can permanently restore the serviceability of the pipe". All the completed engineering testing and analysis shows that by reducing the stress level in the defect region below a threshold level effectively arrests defect growth or defect deterioration. The current Canadian Code accepts the compression technology for corrosion and stress concentrating type defects. In the June of 2003 edition of Z662, the Canadian Standards Association (CSA) recognized the “Steel Compression Reinforcement Sleeve” repair method. With the PETROSLEEVE® meeting and exceeding the Z662 standard criteria, the Oil & Gas Industry can permanently repair their pipelines. Prior to the June 2003 Z662 code issue, the only acceptable method to repair stress concentration type defects (i.e. cracking) was by grinding, welding on a pressure-containing sleeve, or cutting out the defect. The PETROSLEEVE® Pipeline Repair System offers pipeline owners an incredibly cost effective, safe, reliable and proven alternative! for more information, link to our PRESS page, or, download PETRO-NEWS. In CSA Z662-15, the section on Steel Compression Reinforcement Repair Sleeves can be found in clause 10.11.4.4.

Coating and backfill can be completed immediately after installation.

Installation of NPS 20 sleeves or smaller can be installed without any hoisting equipment. Depending on site conditions, it may be useful to have hoisting equipment for sleeves installed on NPS 16 – NPS 28 pipes. All installation tools and products are easily managed by hand. Larger diameters (NPS 30 and greater) require some form of hoisting equipment.
