MINING
EXPANSION JOINTS
Mining Expansion Joints are installed in many types of applications in the mining industry, which is extracting and producing minerals and metals such as:
- Iron
- Lithium
- Copper
- Gold
- Coal
- Molybdenum
- Silver
In the mining industry the Expansion Joints have many applications both in the mining process related pipe lines (trailing systems, at pumps, etc.) as well as in their related processing plants (acid plants, foundries, etc.). The composition of the media in some of these applications within the mining industry set high demands for the material selection of the Expansion Joints. With a proven history of designing high performance Expansion Joints in all types of materials for various critical applications Belman expertly provides highly engineered innovative and quality assured Expansion Joints. Having +25 years’ experince on Expansion Joints is your safety for reliable Expansion Joints for mining applications.

TECHNICAL DESCRIPTION
TYPES & DESIGN
The Expansion Joints types and designs applied in Mining applications are both standard catalogue Expansion Joints as well as customised Expansion Joints designed for the exact application. However Belman mainly see the following types of Expansion Joints used in this industry:
- Tied Expansion Joints
- Hinged Expansion Joints
- Untied Expansion Joints
- Double Bellow Expansion Joints
- Rectangular Expansion Joints
Customised Mining Expansion Joint solutions
As Expansion Joints are used on various applications in the mining industry and for many different medium compositions as well as many different operating data, the design and features of the Expansion Joints are very different from project to project. For some projects austenitic stainless steel is preferred whereas for other projects titanium grades are needed. Belman is highly specialised in finding and designing the best customised solution for the client and the mining application in question.
MATERIALS
Materials
Expansion Joints for Mining applications are made from many different steel and metal types. Mainly stainless steels and higher alloyed steels are used for both the bellow/-s, inner sleeve, flanges, middle pipe and welding ends. Belman can design and manufacture Expansion Joints for the mining industry from:
- All austenitic stainless steels
- Titanium gr. 2
- Titanium gr. 12
- Duplex
- Alloy 59
- 254 SMO
ADVANTAGES
- The correct Expansion Joint solution for the application
- Customised in all kinds of materials, even Titanium
- Cost-efficient solution for critical media applications

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 formier gas, hydrostatic pressure test for all application
