DOWNSTREAM OIL & GAS
High-Integrity Pressure Vessels and Heat Transfer Equipment for Refineries and Processing
Downstream oil and gas operations depend on equipment that performs reliably under continuous duty where compliance requirements are strict and unplanned downtime is costly. LTi Vessco designs and manufactures pressure-retaining equipment and heat transfer systems for refinery and processing environments, delivering bespoke and low-volume fabrication built to meet exacting operational and safety expectations.
From our facility in Bridgend, South Wales, we support UK and international downstream projects with disciplined engineering control, precision welding and fabrication, and verification routes aligned to project requirements.
Downstream Manufacturing Capability
Refinery equipment must perform across pressure, temperature variation, and corrosive process conditions. We work closely with EPCs, contractors, and operators to deliver equipment manufactured to specification and designed for integration into complex plant layouts - including upgrades, replacements, and new-build process systems.
Our approach prioritises consistency, traceability, and clear documentation to support inspection, commissioning, and long-term service.
Equipment We Manufacture for Refineries
LTi Vessco manufactures a range of downstream pressure equipment and fabricated systems, including:
-
Fractionation towers and columns engineered for separation performance and lifecycle reliability
-
Pressure vessels built for downstream duty and project-specific operating conditions
-
Heat exchangers and oil coolers fabricated for thermal performance and plant integration
-
Modular skid packages providing installation-ready systems to reduce site time and disruption
Each unit is engineered for accuracy and produced under controlled fabrication routes with defined inspection stages throughout manufacture.
Engineering Control, Inspection and Compliance
Downstream projects require confidence in integrity, documentation, and inspection discipline. We support refinery requirements through:
-
Controlled manufacturing routes and staged inspection points
-
Fabrication and welding discipline applied to critical joints and complex geometries
-
Third-party inspection where specified, aligned to relevant project codes and standards
-
A quality culture underpinned by HSE&Q expectations throughout design and manufacture
This ensures equipment is supplied ready for installation, supported by the documentation needed for regulated and audited environments.
Trusted by Refineries Across the UK and Beyond
LTi Vessco is an approved vendor to major UK refineries, reflecting years of consistent delivery against strict vendor requirements. Internationally, we have executed downstream projects including deliveries into Denmark and Bangladesh, supporting onshore terminals and export facilities under global client expectations and regulatory scrutiny.
Our track record is built on repeat business from operators and contractors who require dependable performance, compliance confidence, and fabrication precision.
