EXPANSION JOINTS
FOR CHEMICAL PLANTS
Expansion Joints for chemical plants are installed in many types of applications in the chemical industry, such as:
- Fertilizer plants
- Acid plants
- Carbon Black producers
- Methanol plants
- Polymerization plants
- All kinds of inorganic chemical plants (i.e. ammonia and nitric acid)
- All kinds of organic chemical plants (i.e. ethylene oxide)
In the chemical industry, Expansion Joints have many applications, including in steam pipes and process piping, at pumps, at/in heat exchangers and in other diverse apparatuses. The composition of the media in some of these applications in the chemical industry set high demands for both the material selection and design of the Expansion Joints.

EXPANSION JOINTS FOR CHEMICAL PLANTS
CASE STORY
Belman engineered and manufactured a special Expansion Bellow for installation in the compressor lines at a chemical facility in Europe. The Expansion Bellow was delivered with blind flanges at each end of the Expansion Joint, with seals, bolts, a pressure gauge monitor and a ball valve. Due to the client’s critical need of the unit, they wanted to make sure this spare replacement Expansion Bellow could be used immediately when necessary. Therefore the Expansion Joint was kept under pressure during storage. By keeping it under pressure, the intention was to reduce the risk of corrosion on the carbon flanges.

TECHNICAL DESCRIPTION
TYPES & DESIGN
The Expansion Joint types and designs applied in applications in the chemical industry cover both standard catalogue Expansion Joints as well as customised Expansion Joints designed for the exact application. However, Belman mainly sees the following types of Expansion Joints used in this industry:
- Tied Expansion Joints
- Hinged Expansion Joints
- Double Bellow Expansion Joints
- Inline Pressure Balanced Expansion Joints
- Elbow Expansion Joints
- Jacketed Expansion Joints
- Ring Reinforced Expansion Joints
Customised Expansion Joint solutions for chemical plants
As Expansion Joints are used in various applications in the chemical industry and for many different medium compositions as well as a wide range of operating data, the design and features of the Expansion Joints can vary greatly from project to project. For some projects austenitic stainless steel is preferred, whereas for other projects high alloys are needed. Belman is highly specialised in finding and designing the best custom solution for the client and the application in question.
MATERIALS
Materials
Expansion Joints for chemical plant applications are made from many different steel and metal types. Stainless steel and high-alloy steel types are generally used for both the bellow(s), inner sleeve, flanges, middle pipe and welding ends.
Belman can design and manufacture Expansion Joints for the chemical industry from:
- All austenitic stainless steels (i.e. 1.4541, 1.4571, 1.4404, 1.4306 etc.)
- Titanium
- Duplex
- Superduplex
- Inconel 600
- Inconel 625
- Hastelloy
- Alloy 59
- 254 SMO

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
