Expansion joints
for NUCLEAR
Belman is highly experienced in design and manufacture of Expansion Joints for Nuclear Power Plants. The nuclear power industry demands thorough and accurate project documentation. This requires not only a careful study of the extensive project specifications, but often a deep knowledge of the local standards and regulations, design verification, testing and supporting documentation. Due to these stringent conditions the ability to deliver the required documentation is an important consideration when selecting an Expansion Joint vendor. Belman is well known for its complete documented solutions, supporting even small-scale projects with extensive documentation. This ensures Belman’s continued selection as Expansion Joint supplier to the nuclear industry. Being an experienced supplier within the nuclear power industry Belman has been successfully operating in the nuclear industry both directly and through EPC for more than a decade, with a series of significant projects in its reference list.

TECHNICAL DESCRIPTION
APPLICATIONS
Belman Expansion Joints for Nuclear Power Plants are typically installed by the pumps, steam turbines and in transmission lines overall in the system including utiliy, secundary system as well as the primary system.
TYPES & DESIGNS
The Expansion Joint type and design is determined by the point of installation and the specifications as well as the purpose of the Expansion Joint. For Nuclear Power Plants Belman see the following types often used:
MATERIALS
As the media in areas of the system is radioactive the materials used for Expansion Joints for Nuclear Power plants are mainly Austinitic stainless steels with low cobalt content. Furthermore high alloys such as 254 SMO, AISI 904L and Incoloy are used for piping systems in areas where the medium is seawater. Belman can design and manufacture Expansion Joints in materials as per client, application and project requests.

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.
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
