KOMPANSATÖRÜN TANIMI EXPANSION JOINTS DEFINITION The problem of dealing with thermal expansion joints in pipelines has been existing since the first use pipe itself. Firstly, the engineer s simple solution were only pipe bends, omegas and packet slip type joints to absorb the thermal expansion problems. ( Shape 1 ) Today, the expansion joints which consists of a flexible part made of metal, rubber or composite fabric materials are designed. ( Shape 2 ) The purpose of using expansion joints is to solve thermal expansion, mechanical movements and vibration problems of pipelines. Expansion joints absorb the thermal expansion stresses, mechanical movements and vibrations through their flexible bellows element thus easing the pipe stresses. When compared with the pipe element the rigidity of bellows element is very small and practically negligible. Therefore, the expansion joints are considered as zeroload elements. The stresses due to the thermal expansion, mechanical movements or vibrations are compansated by by the bellow which are the flexible parts of the expansion joints. 4
KOMPANSATÖRÜN YAPISI EXPANSION JOINTS STRUCTURE Expansion joints consists of bellows part with one or more ondulations in the general terms and the bellows protection equipments ( liner, external sleeves, tie-rods etc. ) and the fitting elements ( flange, welding-neck etc. ) providing their connection to the relevant piping installation. Ondülasyon ( Körük ) : Ondulations ( Bellows ) : It is the flexible part of expansion joints consisting of one or more ondulations. The number of the ondulations constituting the bellows changes depending on the amount of the total movement. Flanges : The equipment is used for connection of an expansion joints to the pipe system via bolts and nuts. Such connections provide advantage in mounting and demounting. Kaynak Boyun : Weld-Ends : They are used for the purpose of making a welded connection of an expansion joints to the pipe in the installation. Inner Sleeve ( Liners ) : It is one of the expansion joints equipment produced by thin walled stainless steel material mostly in the same quality with the metal bellows material and for purpose of minimizing the contact of the internal surface of the bellows and the liquid. Guide Sleeve : The increased length of the expansion joints brings along the risk of bending. External Sleeve : Limit Rods : The primary function of the limit rods it to limit the axial, lateral and angular movements of the bellows under usual operation conditions. Tie - Rods : They are used for the purpose of limiting the forces over the expansion joints exposed to lateral movements not to damage the bellows. External Sleeve Tie - Rod Inner Sleeve Guide Sleeve External Sleeve 5 Tie - Rod
CALCULATION OF THE MOVEMENT AND SELECTION OF THE EXPANSION JOINTS An example for the selection of the expansion joint from the catalogue is given below. Min. Temperature Tmin : -10 C temperature difference. T Since the temperature difference in our example is 170 The total axial movement is, That value could be rounded off as the closest upper value in the table. L ÇA NOMINAL DIAMETER DN KOMAT BOYU EXPANSION JOINTS FREE LENGTH L KT MOVEMENT 45 180 mm could be as found as the free lenght of the expansion joints. The installation lenght of the expansion joints could be calculated by the formula; The connection type of the expansion joints should be choosen among the following three main groups after total axial movement and free lenght were determined. Flanged Connection Floating Flanged ( DF ) Fixed Flanged ( SF ) Weld-Ends ( KB ) Type Connections
PERIODIC LIFE Design life for the standart expansion joints is taken as 1000 full periods. The real expansion period is realized less due to maximum temperatures are given with higher values to be on the safe side in real life and minimum temperatures are almost never rached due to the insulation applications and higher environmental temperatures than estimated. The ratio of the real expansion to the designed expansion is defined as Periodic Life Factor Fc Real Expansion Designed Expansion Example : is less than the real operation value and the real movement value has been determined as 44 mm. Accordingly ; The periodic life is found from the Graphic of Periodic Life as 3400 periods. 3400 periods safely. GRAPHIC OF PERIODIC LIFE 1.000.000 100.000 10.000 5.000 3.400 1.000 The periodic life, the pressure rate, spring coefficient, stresses and similar design variables for metallic bellows type expansion joints are determined by use of special pc programming constructed according to EJMA standards. 1.2 0.8 0.73 0.6 0.7 0.5 0.4 0.3 0.2 0.1

Put the hose regular coils. INSTRUCTION OF FLEXIBLE METAL HOSE INSTALLATION Dimension the hose adequately. Take care of that the flexible length is not too short. Don t allow the hose to move in only direction. Centre it to permit absorption of half of the movement in both direction. Don t permit axial movement. Install the hose vertically to the direction of movement. Avoid excessive bending of hose. Ose pipe bends if necessary. Avoid extreme lateral movement. Install the hose with a bend of 90 Install the hose in one plane only to avoid torsional twist and moments. Keep the installation plane parallel with the hose plane to avoid inclination.
VALVE JACKETS * Valve jackets are used to minimize heat loss through pipe line armatures and to prevent steam and density made through cooling system and to increase the system productivity. * The maximum temperature allowed for the insulation fabric in standard jackets is approximately 280 C. The WHY USE VALVE JACKETS? Easy to mount and dismount. They are re-usable. They can be re-attatched and used repeatedly when repairing or maintaining equipment. Cost of mounting is very low. They are long lasting. They are provide thermal insulation and are energy saving. They allow for longer lasting equipment. * As temperature of the non-insulated valve surface is observed by thermal cameras C, the temperature of the valve surface insulated by valve jackets is INSTALLATION Jacket is installed on the equipment such that it encompasses the section to be insulated. The alignment of the vectro fasteners on the lower and upper connections is provided. Vectro fasteners are attached to each other. Fitting of the edges on the equipment is provided by drawing the lateral threads.
FABRIC EXPANSION JOINTS Fabric expansion joints are designed to minimize the mechanical movements by seismic, the stress and the mounting defects occurred through the pipe lines by having loaded high thermal dilatation and vibration on itself. max. temperature There are four necessary components in projecting a fabric expansion joints ; Temperature, Pressure, Environment, and Chemical corrosion.
