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 — corrosion, dents, gouges, cracks, faulty girth welds — and lets you fix a damaged section without shutting down the entire line, so the operation keeps running while repairs happen.
Best for leaking defects — wall thickness equal to or greater than the pipe’s maximum allowable operating pressure.
Suits non-leaking defects, where the goal is reinforcement rather than pressure containment.
Dents, Gouges & Grooves
Arc Burns & Surface Cracks
Defective Girth Welds
Lamination Defects & Pinhole Leaks
Reinforcement Pads / Cradles
We custom-build every sleeve to client specification — exact diameter, wall thickness, and steel grade.
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
