What Is a Half Repair Pipe Sleeve?
A half repair pipe sleeve, also called a half-sole or split casing sleeve, wraps around a damaged section of pipe to reinforce it from the outside. Two half-sections are fitted around the pipe and welded together along the longitudinal edges.
This method suits a wide range of pipeline defects, including corrosion, dents, gouges, cracks, and faulty girth welds. A half repair pipe sleeve lets you fix a damaged pipeline section without shutting down the entire line — keeping your operation running while repairs happen, which saves both time and throughput loss.
We custom-build every half repair pipe sleeve according to client specification, so it fits your exact pipe diameter and repair requirement, matching size, wall thickness, and steel grade.
Sleeve Selection Logic
Applications of Half Repair Pipe Sleeve
Our half repair pipe sleeves handle both leaking and non-leaking pipeline defects.
01
Internal & External Corrosion
Reinforces pipe wall thinned by corrosion, restoring load-bearing capacity from the outside.
02
Dents, Gouges & Grooves
Fits around mechanical surface damage without needing to cut and replace the pipe section.
03
Arc Burns & Surface Cracks
Reinforces localized weld-related defects that compromise wall integrity.
04
Defective Girth Welds
Wraps circumferential weld joints that have failed inspection or developed defects.
05
Lamination Defects & Pinhole Leaks
Seals and reinforces small-scale material flaws before they progress.
06
Reinforcement Pads / Cradles
Used for above-ground piping that needs additional structural support.
Built From Certified Carbon Steel Plate
We manufacture half repair pipe sleeves from superior-grade carbon steel plate, following ASTM and international specifications.
We also manufacture in custom steel grades on request, so your sleeve matches the exact specification your project engineer calls for. Carbon equivalency is kept low across our steel plates to ensure strong, reliable weldability in the field.
Production Process
Every half repair pipe sleeve we produce goes through the same three forming stages — never heat treating, which keeps material properties consistent and predictable.
01
Rolling
Steel plate is rolled to match the required curvature and inside diameter of the target pipe.
02
Die Forming
The rolled half-section is die-formed for a precise, consistent fit around the pipe’s outside diameter.
03
Step Braking
Final forming step locks in dimensional accuracy ahead of edge preparation and welding.
Dimensional Specifications
The inside diameter of each half repair pipe sleeve is fabricated to match the outside diameter of standard nominal line pipe. When the two halves are fitted around the pipe, their combined circumference equals the pipe’s circumference, minus a small welding gap along each longitudinal edge.

Quality Control & Certification
Every half repair pipe sleeve is inspected before dispatch, with full traceability from mill to installation.
Standard Inspection
- Full shipment reviewed for dimensional accuracy and material integrity
- Any sleeve that doesn’t meet standards is rejected before it reaches the client
- Mill test reports provided with all materials
- Each sleeve marked with size, thickness, and steel grade before shipping
