Half Pipe Sleeve Installation

Step 1

Inspect the Pipeline

Before installation, the damaged area needs to be evaluated.

The team should understand:

• Damage type
• Damage dimensions
• Pipe condition
• Surface condition
• Operating parameters

Step 2

Prepare the Surface

The pipe surface around the repair area needs to be cleaned according to the approved procedure.

Coatings, dirt, rust and other contaminants may need to be removed where required for inspection, fit-up or welding.

Step 3

Position the Sleeve

The half pipe sleeve is positioned around the affected area.

Correct alignment and fit-up are essential.

The sleeve should correspond to the specified dimensions and clearance requirements.

Step 4

Welding

Where welding is part of the repair design, it must be performed using a qualified welding procedure and appropriately qualified personnel.

Welding on an operating pipeline requires careful control of heat input and other parameters.

The manufacturer's information for related sleeve applications references recognised welding standards including API 1104 and ASME-related requirements.

Step 5

Inspection and Testing

After installation, the repair may require inspection and testing according to the approved repair procedure.

Depending on the design, this can include:

• Visual inspection
• Non-destructive testing
• Dimensional checks
• Weld inspection
• Pressure testing where applicable
