Vessel refurbishment
More than 6,000 vessels have been through our Halifax workshop: stripped by pyrolysis, cleaned on automated shot-blasting lines, examined, upgraded and coated in enclosed spray booths. Every stage is recorded on our digital quality platform, and every vessel returns to service with the PVS seal of approval.
The process
The order matters: each stage prepares the vessel for the next, so the coating bonds properly and every examination happens on clean steel. Every stage is recorded on our digital quality platform.
Our pyrolysis unit removes powder coatings and contaminants, taking the vessel back to a workable surface quickly and consistently.
Bead and shot blasting on our automated lines cleans the shell to Sa 2.5, with a minimum 50 micron blast profile for the primer to key into.
Our highly qualified engineers put every vessel through rigorous safety tests and examinations to TM73, with results recorded digitally.
Valve plates are upgraded to the universal stud pattern, and vessels are fitted with colour-coded durable galvanised steel lids.
A zinc primer coat is applied in our enclosed spray booths for corrosion protection.
An industry-leading top coat, sprayed in an enclosed booth, taking primer and top coat to at least 200 microns combined. The vessel leaves with the PVS seal of approval.
The workshop
Refurbishing thousands of vessels to one standard takes a workshop designed for throughput and consistency.
Strip
A state-of-the-art pyrolysis machine removes powder coatings and contaminants before blasting, quickly and consistently.
Blast
Bead and shot blasting on automated lines gives every shell the same clean surface, to Sa 2.5 with a minimum 50 micron profile, batch after batch.
Coat
Primer and top coat are applied in enclosed booths, away from dust and weather, for an even primer and top coat of at least 200 microns combined.
Quality management
Our quality management process runs on a state-of-the-art digital platform that brings asset management, quality control and recertification together.
Assets
Each vessel is logged and tracked as it moves through the workshop, from intake to dispatch.
QC
Checks at every stage are recorded against the vessel, so nothing leaves without sign-off.
Recert
Recertification is managed and documented on the same platform, alongside the vessel’s history.
Batches
Our haulage fleet uplifts vessels from your sites or depot and brings them back once refurbished, so a batch of returned vessels becomes deployable stock again without you arranging transport.

Pressure Vessel Services (PVS) refurbishes LPG vessels from 450 to 9,000 litres at its workshop in Halifax, West Yorkshire, and has returned more than 6,000 to service. Each vessel is stripped by pyrolysis, shot blasted on automated lines, examined to TM73, upgraded and recoated in enclosed spray booths.
Refurbishment is the cost-effective way to return a sound used vessel to service, while a new vessel suits new installations and specified projects. Our buyer’s guide compares the two.
We refurbish LPG vessels from 450 to 9,000 litres.
Stripping in our pyrolysis unit where needed, bead and shot blasting on our automated lines to Sa 2.5 with a minimum 50 micron blast profile, testing and examination to TM73 by qualified engineers, an upgrade to the universal stud pattern with colour-coded durable galvanised steel lids, then zinc primer and top coat with a combined thickness of at least 200 microns, both applied in enclosed spray booths.
Our quality management process runs on a state-of-the-art digital platform for asset management, quality control and recertification. Each vessel is recorded as it moves through the workshop, so its checks and recertification are documented in one place.
More than 6,000 LPG vessels have been through our Halifax facility. Every one leaves with the PVS seal of approval.
Yes. Our own haulage fleet can uplift vessels from site and deliver them back once refurbished. Tell us how many vessels you have and where they are when you enquire.
Pyrolysis removes powder coatings and contaminants from the vessel before blasting. It makes stripping faster and more consistent, which keeps refurbishment cost-effective.
