Expansion Joint Fabrication & Installation
Oceanx company designs, fabricates, and installs expansion joints for piping and ducting systems across marine vessels, offshore platforms, and onshore oil & gas facilities. Expansion joints absorb thermal movement, vibration, and misalignment in piping systems — protecting critical equipment such as pumps, turbines, and pressure vessels from stress-induced failure.
Our team works with metallic bellows expansion joints, designed and fabricated in accordance with the codes and requirements of the relevant Classification Society (BV or DNV,…..) for each project.
Our Expansion Joint Services Design & Engineering
custom expansion joint design based on system operating pressure, temperature, and movement requirements .
Fabrication
manufactured in-house at our own fully equipped workshop, to Classification Society-approved specifications.
Installation & Replacement
on-site removal of failed/corroded joints and installation of new units aboard vessels and at offshore/onshore facilities, matched to existing flange configurations.
Inspection & Testing
Dye Penetrant Testing (PT) and Hydrostatic Pressure Testing witnessed by Bureau Veritas (BV) or DNV surveyors prior to commissioning Applications
Marine engine room piping systems Boiler and exhaust duct systems (large-diameter metallic bellows) Offshore platform piping Onshore oil & gas facility piping and ducting.
Why Oceanx Company
7 years of experience delivering hundreds of projects across marine vessels and industrial facilities Welders certified by the same Classification Societies (Bureau Veritas / DNV) that approve our expansion joints In-house, fully equipped fabrication workshop Every joint hydrostatically pressure-tested and witnessed by Bureau Veritas (BV) or DNV surveyors before delivery Rapid turnaround for critical repairs, minimizing vessel downtime Full compliance with Classification Society codes and requirements.
Recent Projects Marine Engine Room Piping — Expansion Joint Replacement;
Fabrication and installation of metallic bellows expansion joints for engine room piping systems aboard a vessel, restoring system flexibility and eliminating stress on adjacent piping and equipment.
Boiler / Exhaust Duct Expansion Joint — Large-Diameter Replacement
Removal of a corroded, failed expansion joint from an exhaust duct and replacement with a newly fabricated large-diameter metallic bellows unit, matched to the original flange configuration and duct routing.
Quality Control
Every fabricated joint undergoes weld inspection prior to dispatch, including:
Dye Penetrant Testing (PT)
on critical weld seams to verify weld integrity.
Hydrostatic Pressure Testing
each joint is pressure-tested under the witness of Bureau Veritas (BV) or DNV surveyors before certification for service.
