Belman Academy – providing: Engineering tools, Technical library, Live Trainings, Videothek of training videos. EXPANSION JOINT TYPES FCCU Expansion Joints – highly engineered Expansion Joints for fluid catalytic cracking pipelines in oil refineries. Expansion Joints for liquified gas (LNG/LPG) – customised Expansion Joints for LPG/LNG-carriers, -onshore facilities designed and tested for temperatures down to -169°C. Hydrogen Expansion Joints – special engineered Expansion Joints for hydrogen applications, ammonia applications, methanol applications and alcohol applications. Expansion Joints for scrubbers – for exhaust gas cleaning systems (scrubber) onboard all types of vessels. Also known as scrubbers, scrubber systems, wet gas scrubbers, exhaust gas scrubbers among many other designations. Marine Expansion Joints – for installation in the exhaust systems, scrubbers, auxiliary systems, engines and generator sets. Nuclear Expansion Joints – engineered, tested and documented Expansion Joints for the nuclear power plants. Tank Farm Bellows – specially designed as a flexible connection between storage tanks and manifolds absorbing movements due to tank settlement. District Heating Expansion Joints – are mainly exposed to temperature expansions caused by temperature fluctuations as a result of a system start-up or predisposed operating conditions. Heat Exchanger Expansion Joints – are installed in the heat exchanger itself or in the pipeline connection the heat exchanger and the compressor to accommodate thermal contraction and expansion, by absorbing the movements generated. Axial Expansion Joints – are designed to absorb axial movements (extension and compression in its longitudinal axial direction). The thermal expansion of a straight pipeline section between two fix points can be absorbed by Axial Expansion Joints with a relatively compact build-in length. Lateral Expansion Joints – are used to absorb lateral deflection. Lateral Expansion Joints can move in all lateral directions simultaneously for absorbing expansion from two pipe sections in different directions. Angular Expansion Joints – allow angular movements only, contrary to Axial Expansion Joints which elongate and compress in the pipeline axis. The Angular Expansion Joints move in an angular rotation in one or several planes, controlled by a pair of hinges or a gimbal. Universal Expansion Joints – consist of two multi-convoluted bellows connected with an intermediate pipe into one assembly. Exhaust Expansion Joints – are designed to absorb heat induced expansion and contraction of pipe systems and exhaust systems. The typical pressure rating for Exhaust Expansion Joints, temperature depending is 1.0 BarG. Vibration Absorbers – are designed for versatile usage in any system where pump vibrations occur. The standard range is made from multi-ply bellows with several very thin layers of stainless steel. Pressure Balanced Expansion Joints – can accommodate axial and lateral movements where anchoring of the pipe system is difficult or impractical due to structural or economic considerations. Elbow Pressure Balanced Expansion Joints – used where pressure thrust forces on equipment or piping is unacceptable and the direction of the pipe system also changes. Ring Reinforced Expansion Joints – designed for a working pressure of up to more than 185 barG/ 2683 ps and achieving an optimum combination of both pressure integrity and service life. Used up Jacketed Expansion Joints – are Expansion Joints with another larger Expansion Joint mounted around it, whereby a chamber is formed between the two Expansion Joints. The medium flows through the inner Expansion Joint, while a heating medium, e.g. oil, flows in the chamber between the two Expansion Joints. Crossover Piping Bellows – are typically installed at steam turbines where high-pressure/ high- temperature steam is transferred to one or more low pressure turbines. Externally Pressurised Expansion Joints – absorb very large axial movements under high pressure. In principle, there are no limits to the size of axial movement that can be absorbed by this type of Expansion Joint Clamshell Bellows – provide a very effective solution when a quick and unplanned replacement of the bellows is needed. Clamshell Bellows are two-pieces expansion joints that are welded together on-site. Lens Expansion Joints – Bellows are normally made from multilayers, but in some cases the application requires a single layer bellow and high material thickness (typically more than 4 mm). In these situations, Lens Expansion Joints are used. Rectangular Expansion Joints – For non-circular ductwork Expansion Joints in other shapes can be needed. Belman provide rectangular, hexagon and oval Expansion Joint shapes. HeatComp – Expansion Joint with threaded ends specially constructed for heating installations and ventilation systems. SaniComp – Stainless Steel Expansion Joint specially designed for absorbing movements aseptic applications. Rubber Expansion Joints – are a flexible unit that is manufactured from natural or synthetic elastomers or fluoroplastics and, if necessary, a reinforcement of the bellow (steel, nylon or aramid) is added Fabric Expansion Joints – are extremely flexible and can be made from a variety of special woven fabrics coated or laminated with selected elastomers or fluoropolymers. Metallic Flexible Hoses – are very flexible, they can absorb large movements and can be supplied with customised lengths to suit the installation.
