PVC and Carbon Steel, corroded after 12 Years exposure to sea water

Introduction

The drainage system had sections of carbon steel piping fitted that required repair after suffering internal corrosion due to being in service for 12 years. They had been initially installed with a non corrosion resistant alloy with an original design life of
only 2 years.

Internal corrosion and large loose scale deposits had caused frequent snagging and blockages. A full clean and removal along the length of carbon piping with replacement was required. Due to the location and nature of the system the Picote cleaning and coating system was deemed the ideal solution.

Following a consultation with our experts, it was decided our brush coating offering would be appropriate for the repair and future-proofing of the drainage system. This solution required less equipment and no lateral cutting to the pipework.

The Process

Picote Brush Coating™️ offered minimal disruption, avoiding costly replacement. The coating provides a damp proof, corrosion resistant, wear resistant and non-corrosive lining. This was a perfect solution for seawater-eroded pipelines.

The team worked solidly for eight days aboard the rig to complete the job with great feedback from the client.

They cleaned the pipes with Picote high-speed cleaning using a Picote Mini Miller supplied by S1E Ltd in the UK. The cleaning was completed using Picote Cleaning Chains and Cleaning Brushes. The team took care to disconnect the pipework from the macerator prior to descale to prevent possible damage of the waste-handling system.
Outside connections were uPVC piping which required further care to clean as they were hard to reach transition and mastic joints, which must remain intact.

Picote Brush Coating™️ System

Old or deteriorated drains and sewers from DN32-300 /1¼" to 12" diameter can be renovated with the Picote Brush Coating™ System. The coating applied provides a damp-proof, corrosion resistant, wear-resistant and non-corrosive lining. Several coats can be applied within the same pipe. Renovate entire piping systems for example apartments or blocks of flats with minimal disruption, avoiding costly excavation.
