EXPANSION JOINTS FOR
LIQUIFIED GAS (LNG/LPG)
CASE STORIES
EXPANSION JOINTS FOR FSRU
Remarkable Expansion joints for a LNG carrier which is being converted into a FSRU. The Expansion Joints are tested at -165°C and for 66,35 barg
EXPANSION JOINTS FOR FLNG
These Expansion Joints are made from Duplex and Superduplex as the media and the sourrounding environment requires special materials to avoid corrosion.
GUIDING THE CLIENT ON IGC/DNV
A significant challenge is to understand how the IGC/DNV rules apply for Expansion Joints, as well as the connecting piping, Belman helped the client on that.

TECHNICAL DESCRIPTION
APPLICATIONS
All ways of transporting and processing liquefied gas set demanding requirements. As Liquid gas is considered a hazardous medium and with safety being paramount this is a highly regulated area with severe demands for the application itself as well as the components installed in these applications.
Our Expansion Joints for liquified gas (LNG/LPG) for among others:
- Pipelines from and to cargo tanks
- Outlet of pumps
- Cooling systems on LNG pipes
- Pipelines leading to regasification module
- MEG (Mono Ethylene Glycol) modules
VESSELS (LNG/LPG carriers & LNG-fuelled ships)
With the liquid gas being onboard vessels this set high demands for the correct design as well as meeting the limitations on space onboard the vessels. The Expansion Joints are either installed in the engine and exhaust system or at the pipes at the tanks. On LNG carriers the gas stored in large steel tanks and all cargo pumps are discharged into a common pipe which runs along the deck of the vessel. It branches off to either side of the vessel to the cargo manifolds used for loading or discharging. On the carrier, each gas tank is mounted at an anchoring, which allows the gas tank to move. Expansion Joints are installed at each anchoring to absorb these movements.
SPECIAL OFFSHORE UNITS
As offshore units and vessels such as FLNG, FPSO and FSRU are considered vessels the same rules and demands apply for them as for the Vessels such as LNG carriers.
ONSHORE FACILITIES
In onshore facilities Expansion Joints are installed in many parts of the plant being in the piping systems themselves, at turbines, pumps etc. No matter the location the rules and demands applied for this media type applies.

REQUIREMENTS & CODES
Demanding requirements for Expansion Joints
Designing and manufacturing Expansion Joints for liquid gas applications such as LNG carriers is always a challenge. The main reasons of this are:
- The temperature in cryogenic range
- Pressure constraints
- Safety factors
- Constraints specific to the ship’s hull, e.g. hogging and sagging
- Requirements for third party construction approvals and final inspections
- Full documentation needed
Challenging medium
Liquefied gas is the liquid form of the substance which, at ambient temperature and at atmospheric temperature, would be a gas. Most liquefied gases are hydrocarbons and the key property that makes hydrocarbons the world’s primary energy source – combustibility – also makes them inherently hazardous. Liquefied gases are handled in large quantities, and it is crucial for vessels carrying them and facilities handling and operating them to be safe. This set high demands for all components used, and also for the Expansion Joints. Being aware of the these issues, Belman is the go-to supplier for your Liquid gas projects involving Expansion Joints.
