Expansion Joints for chemical plantsEXPANSION JOINT DESIGNS FOR CHEMICAL PLANTS 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 Custom 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. DIMENSIONS & MATERIALS FOR EXPANSION JOINTS FOR CHEMICAL PLANTS Belman Expansion Joints for chemical plants are available in the following design data range: Dimensions: DN 25 - 12,000. Pressure: From full vacuum up to 150 barg or more if required. Temperature: Design temperature range from -256°C to +1000°C. 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 • 254 SMO • Alloy 59 EXPANSION JOINTS SINCE 1994 Since 1994, Belman has specialised in the design and manufacture of cost-efficient, custom Expansion Joints for clients across industries worldwide. This has established Belman as a recognised provider of custom Expansion Joints for the client’s specific requirements and/or project.Page 3Page 5

EXPANSION JOINT TYPES FOR CHEMICAL PLANTS TIED DOUBLE BELLOWS This type absorbs larger axial and lateral movements than the single bellow. The tie rods control the movements that are absorbed. Other connection ends are available on request. HINGED EXPANSION JOINTS This type absorbs angular mo- vements and the hinges provide stability. These Expansion Joints are available with flanges and welding ends. PRESSURE BALANCED EXPANSION JOINTS This type absorbs axial movements and can also absorb lateral move- ments. They are available with both internal limiters (inline) and with exter- nal limiters. ELBOW EXPANSION JOINTS This type absorbs axial movements and can also absorb lateral move- ments. It is available with one or two working bellows. RING REINFORCED EXPANSION JOINTS This type absorbs movements under high operating pressures. Ring rein- forcement ensures pressure integrity and stability. JACKETED EXPANSION JOINTS This type of joint is used for pipelines with media that solidify. A chamber is placed between the two Expansion Bellows that allows a heating medium to run, thereby avoiding solidification of the medium. OTHER EXPANSION JOINT TYPES FOR CHEMICAL PLANTS Belman offers a large range of Expan- sion Joint types and designs involving Gimbal Expansion Joints, Double Hin- ged Expansion Joints, 2-ply testable bellows etc. All of which can also be installed in chemical applications. Customised for chemical plants Belman also has expertise in cus- tom-building Expansion Joints for specific projects in the che- mical industry. We will gladly design specific Expansion Joint solutions for your projects.
