Expansion joints for
THE MARINE INDUSTRY

Expansion Joints are widely used in the Marine industry. As trouble-free operation and safety is crucial onboard any vessel, to avoid a vessel stopped in the middle of the sea. This fact and marine conditions such as corrosive media and sourroundings set demands for equipment installed being of the correct material, product quality, design as well as covered by the approvals specified by the classification society. No matter the application, Belman has extensive experience and expertly design, test and manufacture of Expansion Joints for a large range of vessel types and applications onboard them including:

CASE STORIES

254 SMO EXPANSION JOINTS

Expansion Joints for exhaust gas cleaning (Scrubbers) for a passenger ship. Expansion Joints for Scrubbers are often made from 254 SMO.

Bulk carrier scrubber expansion joints
URGENT DELiVERY

A Bulk carrier was in urgent need for a replacement Expansion Joint for their scrubber system. Belman helped out by offering extremely short delivery time.

Alloy 59 scrubber expansion bellows
ALLOY 59 WAS THE SOLUTION

In some situations, austenitic stainless steels and 254 SMO is not resistant to the media in Scrubber system. In those cases, Alloy 59 is the solution.

EXPANSION JOINTS FOR THE MARINE INDUSTRY

TECHNICAL INFORMATION

MATERIALS

Vessels operate with corrosive media and in corrosive environments and this set high demands for equipment installed. This equipment including the Expansion Joints needs to be of the correct resistant material, product quality, design as well as covered by the approvals specified by the classification society. The media and the operating data of the vessel determine the material requirements for the Expansion Joints.

Belman offers Expansion Joints in a wide range of materials. Belman is highly experinced on the material selection for marine vessels. The materials mainly used are:

  • 254 SMO (1.4547)
  • Alloy 59
  • 1.4539 (AISI 904L)
  • Duplex
  • Superduplex
  • 1.4571 (AISI 316 Ti)
  • 1.4404 (AISI 316 L)

 

Material selection
Many marine vessel experience issues with the material of their components not being resistant to the acidic, salty and corrosive environments they operate in. Often higher alloyed chloride and acid resistant materials. Selecting the correct material therefore is crucial for trouble-free operation. Furthermore Expansion Joints may have to be designed with inner sleeves due to high media velocities and choice of material will be that of the bellow.

Belman has seen many situations were the vessels are struggling with unplanned stops due to leakages on their Expansion Joints. As the Expansion Joints are a wearing part the problems will show first here. To help clients Belman has made a case study on material selection for scrubbers, and this can serve as a guideline for other applications onboard the vessels as well. Furthermore Belman has made a video explaining this issue:

QUALITY & TESTS

Belman is known for high quality products and therefore our quality control is a fundamental part of our business. All processes during production designed by the Belman quality engineers, is strictly follow and implement according our procedures and instructions and carefully inspected by Belman quality inspectors. All checks and inspections are done according to the strict prevailing Belman quality control procedures which is part of the Belman ISO 9001 quality management system approved by DNV.

Classification Societies
Belman hold type approvals from several classification societies such as NK, DNV, BV, RINA and furthermore Belman hold the BV Mode I certification. Belman can guide clients on the requirements and design the exact Expansion Joint neded to meet requirements and operating parameters.

ITP & Test
Inspection test Plan generated by the quality management system makes sure that each step of manufacturing has the appropriate inspection points such as Hold and Witness points.

Based on manufacturing code, project specification, application, media, and eventual ship classification rules Belman performs a large variety of quality tests including destructive, non-destructive testing and proof testing. All tests can be witnessed by the 3rd part based on the customer and classification requirements.

  • Destructive test: such as life cycle test and burst test to validate the design, i.e., vessels and offshore platforms
  • Non-destructive test such as Visual testing, dye penetrant test, Radiography examination, Magnetic testing, ultrasonic testing, hardness testing and PMI for all applications
  • Proof tests: leak test with air, leak test with helium and former gas, hydrostatic pressure test for all application
