1. Description of the System

4

A new permanent rehabilitation solution for liquid and gas pipelines

Economical method of reconditioning the pipeline’s parameters without

shutting down operation

Rehabilitation of areas of external corrosion, gouges, grooves, arc burns,

dents and other mechanical damages

For reductions of wall thickness down to 20% of original thickness

Tested and certified by an accredited third-party laboratory (TÜV Nord)

1. Description of the System

5

System works for pipelines from DN 50 up to DN 1500

Maximum temperature of 82°C

Non crimped type of reinforcement fabrics as opposed to woven fabrics

Materials come with a 3.1 certificate

Woven fabric stitched fabric

2. Technical Description

6

Prepare the pipeline and the weakened area

Use of putty to assure energy transmission

Use of primer to assure bond strength between pipe and composite

Prepare the barrier and the carbon fabrics

Wrap the pipeline with the barrier and the carbon fabrics

After curing process the pipeline is re-stored to its MAOP

2. Technical Description

18

Before application the demand of material has to be identified

A basic calculation software is used

Parameters of pipeline, failure dimensions and pipeline conditions during

application are entered

Software calculates regarding modified ASME B31G the required number of

layers to restore pipeline to its design pressure
