The PETROSLEEVE® is a permanent, non-intrusive Repair System that is easy for any crew to perform. The carrier pipe is cleaned, epoxy applied, PETROSLEEVE® assembled and compressed, and then the PETROSLEEVE® is welded together... all in about an hour.

  • Complimentary EIP (Engineering Installation Parameter) Software calculates, records and confirms stress conditions following each installation
  • Each sleeve has a unique serial number to facilitate manufacturing and installation traceability
  • During manufacturing, each PETROSLEEVE® is pre-fitted to confirm tolerances
  • Operators receive instant confirmation of successful installation immediately after repair is completed

Quality Assurance: The PETROSLEEVE® is tested and validated as a permanent pipe repair. The PETROSLEEVE® is the only pipe repair, short of defect removal, that repairs cracking, and it does not require welding to the pipeline. Additionally, each PETROSLEEVE® installation is verified using quality control procedures in association with our complimentary Analysis/Documentation EIP software. The PETROSLEEVE®:

  • Maintains constant compression on the carrier pipe and never disbonds from the pipeline
  • Permanently restores the integrity of the pipe
  • Alleviates concerns related to high CE, thin wall, and high strength steels (X70+) that are difficult to in-service weld
  • Installs in all weather conditions
  • Permanently repairs defects, arresting any defect growth
  • Interference fit ensures steel to steel contact, which will allow the pipeline’s corrosion protection system (e.g. cathodic protection) to also protect the PETROSLEEVE®

How It Works - Defect Repair Details

The PETROSLEEVE® successfully applies compressive forces to both the pipe and the defect. First, the sleeve’s compressive forces contain the expansion of the pipe under pressure. Second, the sleeve’s compressive forces place the repair area into compression for all operating ranges. Simply put, an installed PETROSLEEVE® keeps the pipeline in a compressive state, eliminating any possibility of defect failure. A PETROSLEEVE® installation:

  • Reinforces the pipeline defect area, essentially creating a heavy wall section
  • Ensures that defects (even Stress Concentrator defects) cannot grow
  • Overcomes pipeline expansion from pipeline operational forces
  • Prevents separation between the PETROSLEEVE® and pipeline within all pipeline operating ranges. The pipe and PETROSLEEVE® move and act as a single unit.
  • Transfers stress from the pipe to the PETROSLEEVE®
  • Confirms integrity of the repair through reporting, QA and site validation

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



Pipe Body Cracking is caused by various means, including chemical action (Stress Corrosion Cracking). Seam Cracking occurs when anomalies in the seam act much like a pipe body crack. Failure occurs when the crack becomes unstable and the pipe wall can no longer resist the crack growth.

The installation of a PETROSLEEVE® permanently reduces the stress state in the material surrounding the defect, eliminating the possibility of crack extension


Corrosion defects are caused by a chemical reduction action on the surface of the pipe material, resulting in localized thinning of the pipe wall. Failure occurs first by bulging (yielding) at the corrosion site, followed by rupture of the steel membrane.

The installation of a PETROSLEEVE® provides mechanical support to the localized thinned section. It is this support that prevents bulging for all pressures, including during high pressure testing.

Gouge, Groove or Arc Burn

These defects are caused by either third-party damage or non-acceptable workmanship, and may develop stress concentrators such as cracking anomalies due to higher stress levels in the pipeline. Failure occurs by the pipe material containing the defect flexing from internal pressure variances, which in turn causes cracking. When the crack extensions become critical, rupture occurs.

The installation of a PETROSLEEVE® eliminates flexing in the pipe material and the stress state in the material surrounding the defect is put into compression. This eliminates fatigue, crack extension, and rupture.


Dent defects are caused by either third party damage, unforeseen underground rocks/obstructions or poor backfill and/or excavation practices. As in a gouge, groove or arc burn defect cases, failure occurs when the pipe material containing the defect flexes during internal pressure variances. This flexing causes cracking and when crack extensions become critical, rupture occurs.

The installation of a PETROSLEEVE® permanently locks the dent deformation of the dent shape into place. This prevents flexing in the pipe material dent shoulders by placing the pipe material into compression and consequently eliminates fatigue, crack extension, and rupture.

Girth Weld

Girth weld defects are caused by poor workmanship. Failure occurs when the strength of the weld is not sufficient to counteract the applied forces.

The installation of a PETROSLEEVE® permanently reduces the stress state in the material surrounding the defect, as well as providing support to the weld. The PETROSLEEVE® provides permanent mechanical support to the weld area and reduces the strain induced in the weld by the external forces.

Grind Defect

A grind defect is caused by mechanically removing metal from the surface of the pipe material that results in localized thinning of the pipe wall. In addition, stress concentrators could be present on the metal surface. Failure occurs first by bulging (yielding) at the grinding area, followed by rupture of the steel membrane. Further, the presence of stress concentrators may act as initiation points for rupture at lower strain levels.

The installation of a PETROSLEEVE® prevents bulging by permanently providing mechanical support to the localized thinned section. The sleeve also eliminates metal movement (fatigue), and reduces the strain induced in the material by the external forces.


Manufacturing defects are those that are introduced during the pipe manufacturing process. These can form part of the body of the pipe or within the seam weld. These defects can include but not be limited to dents, scars, gouges, cracks, laminations or welding defects. Manufacturing defects can be repaired with the use of the PETROSLEEVE® Pipeline Repair System depending on the type of defect and applied defect principles described above.


A leak occurs when a defect in the pipe wall allows the pipeline contents to escape while the pipe wall continues to contain the internal pressure, preventing a rupture from occurring. Active internal and/or external corrosion will proceed through the wall of the pipeline if left unmitigated. A leak may also be a result of anomalies from pipe manufacturing or welding.

Although testing and research in a controlled setting has proven that the installation of a PETROSLEEVE® is effective in preventing a through-wall from leaking beyond the sleeved area, the PETROSLEEVE® has not been approved for use on these defect types at this time.
