What Tiverton Fabrications does

Tiverton Fabrications Limited is a precision welding and fabrication specialist founded in 1983, operating two manufacturing facilities in Tiverton Business Park, Devon, South West England. It designs and manufactures bespoke metal pressure vessels, vacuum chambers (including UHV configurations), welded tubes and cylinders, cryogenic vessels, and specialist scientific instruments using TIG, MIG, and orbital welding (Lorch Turn 500) with CNC turning, milling, and vertical boring up to 2000mm diameter and Butler Elgamill capacity up to 3200mm. The business holds ISO 9001:2015, TUV AD2000 HP0 (pressure vessel manufacture and inspection), and BS EN ISO 3834-2:2021 (fusion welding) certifications, supported by an in-house Helium leak detection facility (Alcatel ASM 181T, sensitivity 2.0 x 10-12 mbar ls-1 He), pressure testing up to 2 bar, and FARO-arm CMM inspection, and works in stainless steel, aluminium, copper, and exotic alloys including Hastelloy, Inconel, and titanium.

The company serves OEMs, Tier 1 suppliers, engineering firms, and research institutions in medical/healthcare (notably MRI cryogenic vessels at ~10-12 units per month repeat), scientific research (NMR spectroscopy vessels, UHV chambers), energy (LNG transfer vessels, cryogenic storage), aerospace and defence, industrial manufacturing, and food. Revenue is generated through quote-based, project-priced B2B enterprise contracts spanning one-off bespoke builds and repeat production runs, with a direct field-sales motion through web, phone, and email, plus customer referrals and group-level channels following its January 2026 acquisition by Expromet Technologies Group, where it now serves as the group's centre of excellence for fabricated solutions.

Following the acquisition, Tiverton Fabrications combines its welding, fabrication, and assembly capabilities with the parent's casting and machining operations to offer a comprehensive end-to-end manufacturing solution to global OEMs and Tier 1 suppliers, while continuing to operate from Devon with deliveries spanning the UK (Oxford, Bristol) and international markets (France, Switzerland, Japan).
