EMAT component manufacture in the UK for intelligent pigging

11 Mar 2026

Specialist miniature and complex component engineers at OF Bell manufacture bespoke EMAT components for use in global pigging and pipeline inspection technologies.

EMAT components manufactured in the UK by OF Bell are an integral part of pigging, pipeline integrity and inspection technologies used around the world that keep utilities, including oil and gas, flowing freely to serve millions of people daily. 

Engineered and assembled entirely in-house by our UK-based, experienced complex component engineering team in Bishop Auckland, County Durham, EMAT skid plates are applied in non-destructive pigging testing, condition monitoring and diagnostic engineering technologies backed by ISO-certified quality and confidentiality standards that protect your organisation's commercial interests at every stage.

EMAT components manufactured in the UK for accurate pigging & pipeline integrity management

"EMAT" - Electromagnetic Acoustic Transducer components are used in ultrasonic technologies when testing and managing pipeline integrity.

Engineered, manufactured, assembled and tested by OF Bell's in-house complex engineering team, together with wound coil components, transformers and solenoids including MFL (Magnetic Flux Leakage) sensors for the pigging and pipeline integrity sector, precision EMAT components are supplied to leading onshore oil and gas technology innovators following thorough testing that ensures accuracy, reliability and consistency in every unit.

Expert engineering of EMAT components for intelligent pigging 

EMAT components by OF Bell's UK-based engineering team are used in our clients' intelligent pigging and pipeline integrity management technologies worldwide, performing consistently and accurately at high temperatures and during movement. 

An alternative to MFL sensors and simple to deploy in situ, versatile EMAT components manufactured in the UK by OF Bell are used in in-line inspection (ILI) operations across a broad range of conditions to detect cracks, corrosion, leaks, mechanical damage and other pipeline defects that may lead to faults and loss in the utility supply.

OF Bell engineers and manufactures entirely bespoke EMAT components to our clients' specifications, suiting a range of intelligent pigging tool sizes according to use. 

Precision engineering of EMAT components used in intelligent pigging & pipeline inspection

A miniature and complex component engineering specialist, OF Bell applies precision engineering expertise to manufacture EMAT components under one roof at our UK facility in Bishop Auckland, County Durham. 

EMAT technology is versatile, allowing for excellent operator control of the frequency domain and wave modes. Relatively high frequency (RF) coils and magnets efficiently enhance signals, generating different waves as required according to the coil and magnet combination used.

With facilities including miniature coil winding down to just 0.0125mm, and miniature injection moulding of robust plastics with shot weights from 0.5g, components engineered and manufactured by OF Bell allow for accuracy and precision in the field, benefiting from our team's excellent understanding of sensor and fault detection technologies, including intelligent pigging processes, gained through years of collaboration with clients operating in the pigging and pipeline inspection sector.
