Product Description & Function

The Welding Pig is a special pig developed by PE to seal

the ends of pipes. This pig allows pipe welding to be

carried out prior to laying land based pipelines or on

vessels prior to placement subsea.

The Welding Pig is used to create an inert atmosphere in

the pipe so that welds can be carried out.

PEs Welding Pig is suitable for pipe sizes from 8 and

above.

Features

> Single module tool

> High strength steel body

> Fitted with PEs Omnithane polyurethane inflatable sealing tyres

> The two separate sealing tyres are inflated independently for maximum integrity

> Unique sealing tread which is pushed against the pipe wall in a dual action to both seal and grip the pipe

Benefits for Operators

PEs Welding Pig provides many benefits:

> Easy to insert into pipes

> Easy to remove when either mid-line or end-line tie-ins are completed

> All required work can be completed onsite

> Suitable for refurbishment and reuse leading to significant cost savings

Design, Development and Testing

Engineering expertise is used to design, test and

build the Welding Pig to meet the exact

requirements of the pipeline where it will be used.

Computer aided design capability is used to

develop the Welding Pig and if required, prototype

pigs can be tested in purpose built test loops.

On-site Services

Our Engineering Team isavailable to provide support

services worldwide. All our

engineers are fully certifiedand trained for onshore and

offshore operations.

Insertion, Operation and Removal

The Welding Pig is positioned in the pipeline and

the sealing tyres are inflated with water or air using a

connector hose to inflate the tyre connection to hold

up to 2 bar differential pressure.

When the required welding has been completed, the

Welding Pig can be pigged or pulled from the

pipeline.

PE works with its clients to ensure all operational

requirements are met in the functionality of the

Welding Pig.
