TANK FARM BELLOWS

We provide a comprehensive range of stainless steel expansion joints for tank farm applications. Tank Farm Bellows are specially designed as a flexible connection between storage tanks and manifolds absorbing movements due to tank settlement.

Highly customised design
This type of expansion joints looks like standard expansion joints, but they are specially designed for this particular application which requires a high reliability during the entire service life of the storage tank.

DIMENSIONS

Customised solutions
Diameter, installation length and design criteria can be changed upon customer’s request and are available in all sizes up to DN 12.000, all designs and all materials.

 

Standard solution

  • Dimensions: DN 80 (3”) – 600 (24”)
  • Built-in length: Standard installation lengths of 1500mm, 2600mm or 3200mm
  • Movement/settlement: Absorbs lateral movements / tank settlements of 200 mm
  • Design pressure/ Temperature: Suitable for 19,5 barg at 100°C
  • Materials:
    Bellow elements and inner sleeve from Incoloy 825, which offers superb resistance against corrosion.
    Steel parts such as flanges, pipe ends and middle pipes are made from ASME materials such as A105, A106 Gr.B.
    All carbon steel parts will be provided with a standard multi-layer coating system, suitable for outdoor installation or a coating system specified by the project/client
  • Service life: 20 years as standard – though this is naturally dependent on the exact operation parameters and design specifications

ADDED VALUE

Tank Farm Bellows provide:

  • A reliable alternative to VJ couplings
  • Reduced chance on unwanted spills
  • Absorb large movements; both lateral and angular
  • Extended service life
  • Easy replacement with flanges and the build-in length can be customised
  • Guarantees a 100% clear bore and no disturbance of flow for the medium due to the specially designed integrated inner sleeve

QUALITY ASSURANCE

The Tank Farm Bellows comply with PED/CE. If required the Tank Farm Bellows can be designed and calculated according to EJMA, ASME, EN and AD2000.

The Tank Farm Bellows are delivered with fabrication book, declaration of conformity (DOC) and user guide. As a full NDE has been carried out in our workshop, no additional on-site tests are required and the expansion joints are ready to install.

Quality approvals
We hold all necessary approvals and type approvals for supplying to the oil & gas industries such as EN ISO 9001, PED, EN 3834-2, AD2000 and type approvals by Bureau Veritas, Lloyd’s Register, DNV-GL. We are familiar with working with applied design codes and standards such as; PED, NORSOK, ASME, EJMA etc.

Experienced
As we are often involved in projects, where expansion joints are a part of a critical application, we understand the importance of the supporting
documentation. Firstly, the provided specifications are studied and a close dialogue with the client begins. Following which we produce the detailed quotation, supporting
calculations, complemented by extensive quality control and testing procedures as a part of the project documentation. Additional to this is the inspection of welding consumables, materials and a sub-supplies audit, test, documentation and final inspection.

Oil refinery benefitted from
SHIFTING VJ COUPLINGS
TO TANK FARM BELLOWS
A Dutch refinery wanted to reduce unwanted spills and sought a more reliable, flexible connection between their storage tanks and manifolds.
