History

Spromak was founded in 1982 by Paul Sproson with a vision to manufacture and supply branch reinforcing fittings, commonly referred to as olets, to the oil, gas, petrochemical, and other related industries.

Paul has a background in the oil and gas industry dating back to 1972 and, in 1980, joined an American manufacturer as their Sales Manager to set up a new manufacturing division based in Liverpool. In 1982, Paul purchased the assets of the company and established Spromak, operating from a 7500 sq. ft factory in Huyton, Liverpool. 

Within months of startup, the company obtained Shell manufacturing approval and was awarded the contract to supply all Shell UK and Shell International projects globally. In 1990, Spromak was awarded its first contract exceeding £1 million GBP from Amerada Hess for the Scot Field project and went on to win other major contracts, including the supply of over £5 million GBP of branch connection fittings to the Gorgon project, Barrow Island, Australia in 2015.

Spromak has since gained approvals from other major oil, gas and energy companies including National Grid, Exxon, BP, Chevron, Equinor, Aker, Aibel , PDO and ADNOC to name a few.

Capabilities

Spromak is now a multi-disciplined UK engineering company, focusing on manufacturing excellence for critical piping components used within the energy industry. We’re a renowned manufacturer of forged reinforced branch fittings, flanges and other specialised forged components for piping and pressure vessel applications.

Utilising our own UK manufacturing facilities and further supported by our manufacturing partners within Europe, we also offer an extensive portfolio of specialised products, such as, API 6A and 17D weld neck and swivel flanges, cross over tees and elbows, target and cushion tees, flow venturis, swept outlet flanges, transmitter housings, injection stabs, valve bodies, stems and bonnets.

Our robust production system ensures clear visibility and control of all critical manufacturing activities, from component design and verification, forging and production methodology, heat treatment, destructive and non-destructive testing, through to final certification, data books and project dossiers.

Manufacturing Operations

Our UK operations are spread across two manufacturing sites, each dedicated to excellence in component design and engineering, forging, machining, material testing, and certification.

Our NORSOK M-650 approved forge, situated within a 15,000 sq. ft facility in Birmingham, is equipped with 2,000 and 1,000 tonne drop hammers, along with several clear space, clipping, trimming, and setting presses. The site also features three furnaces and a comprehensive tooling machine shop. With over 300 bespoke closed-dies, our forging production ensures near-net shapes and optimal grain flow, enhancing material properties.

In Liverpool, our machining, testing, and inspection centre spans a 28,000 sq. ft facility. This site houses 15 modern CNC machines, supported by both traditional metrology and coordinate measuring inspection equipment. Our NDE inspection capabilities include dye penetrant, ultrasonic, magnetic particle, PMI, hardness, and feritscope testing.

Engineering

Our in-house engineering expertise is extensive, encompassing highly experienced piping engineers, design engineers, metallurgists, skilled tool makers, forgers, and machinists.

Our historically proven manufacturing routes, material qualifications, and procedures are aligned, enabling us to produce specialty products with exceptional quality. These include heavy wall thickness duplex and super duplex, high yield carbon steels with CRA overlay, chrome-moly, and high yield carbon steels, all meeting the high standards you would expect from a leading manufacturer.

Design

Utilising our internally developed and proprietary piping design software, we’re able to quickly generate innovative solutions, supported by in-depth analysis and design calculations verifying compliance to piping standards such as API 6A, API 17D, ASME B31.1, B31.3, B31.4, B31.8 and ASME VIII Divisions 1 and 2.

Our proprietary design software is further supported by 3D CAD/CAM and FEA capabilities. Our continued investment in industry leading software ensures the production of high integrity products and, in parallel, the reduction of lead times and costs for our clients.

With the support of the LFF Group, we leverage a 40+ year database of component design and material properties, including subsea and high-pressure flanges, fittings, and connectors. This database can be used to assist with the management of aging assets and in producing obsolete components, bridging the gap between legacy and modern systems utilising specialist solutions.
