HEAT EXCHANGER
EXPANSION JOINTS

Las juntas de expansión para intercambiadores de calor se instalan en el propio intercambiador de calor o en la tubería de conexión del intercambiador de calor y el compresor para acomodar la contracción y expansión térmica, absorbiendo los movimientos generados. Las juntas de expansión para intercambiadores de calor ofrecen la solución óptima para gestionar y controlar los movimientos generados en los intercambiadores de calor y, por lo tanto, garantizar un funcionamiento seguro y fiable. Como esta aplicación opera bajo alta presión, requiere juntas de expansión para intercambiadores de calor con un diseño especial y de fabricantes con experiencia. Belman diseña y fabrica de manera experta juntas de expansión para intercambiadores de calor de acuerdo con muchos códigos de diseño, especificaciones de diseño y normativas de la industria diferentes requeridas por el cliente y la aplicación.

CASE STORY

Para la instalación en una sección de tubería de vapor de escape en una planta química en Europa, Belman diseñó y fabricó una junta de expansión de alivio de esquina para reducir las fuerzas que actúan sobre la boquilla del intercambiador de calor. Esta solución absorbe los movimientos térmicos en ambas direcciones, reduciendo al mismo tiempo el empuje de presión en la conexión. Debido a la ubicación en la planta, la junta de expansión se fabricó íntegramente con Hastelloy.

HEAT EXCHANGER EXPANSION JOINTS

TECHNICAL DESCRIPTION

MOVEMENTS

In the Heat Exchanger
As the Heat Exchanger per design is a cylindrical shell containing a bundle of tubes. axial expansion between the shell and the tubes is a well-known challenge for heat Exchanger designers. Expansion Joints are installed in Heat Exchangers to accommodate these axial movements, as the tubes and the shell in Heat Exchangers do not expand in a uniform way due to varying materials, temperatures as well as other factors. If the Heat Exchanger is not designed to control these movements (expansion) this will cause damages on the heat exchanger. By installing Heat Exchanger Expansion Joints in the outer shell, movements are absorbed and pressure integrity and durability of the Heat Exchanger is achieved.

In the piping system around the Heat Exchanger
The movements generated in the piping system by connected equipment, fluctuations in temperature in the piping as well as pressure and pressure changes are specific for each piping system. No matter if they are axial, lateral or angular movements the Expansion Joints can be designed to handle and control these to protect the piping system and connected equipment.

Belman is experienced in customised Heat Exchanger Expansion Joints to the exact application.

TYPES & DESIGN

Belman designs and manufactures a wide range of Heat Exhcanger Expansion Joints for installation in heat exchangers and the piping system around the heat exchanger. Heat Exchanger Expansion Joint design and types are selected based on wether they are installed in the Heat Exchanger itself or in the piping system around the heat exchanger. The design of the Expansion Joint is specified by the amount of movements, the media and the operating parameters in the Heat Exchanger and its piping system.

Design
For most applications the Heat Exchanger Expansion Joints used are multi-ply bellows with ring reinforcement, but some clients prefer thick walled singly ply bellows (Lens Expansion Joints). For the piping aorund the Heat Exchanger Pressure balanced Expansion Joints are applied. The designs mainly used are:

RING REINFORCED
EXPANSION JOINTS

By supporting a multi-layered Expansion Joint bellows with ring reinforcement, an optimum combination of both pressure integrity and service life is achieved.

UNRESTRAINED AXIAL
EXPANSION JOINTS

Inside the Heat Exchanger unrestrained Expansion Joints with welding ends are often used.

LENS
EXPANSION JOINTS

Lens Expansion Joints are single layer bellows, with a greater material thickness. In heat exchangers and equipment operating under high pressure this type is often preferred.

PRESSURE BALANCED
EXPANSION JOINTS

Pressure Balanced Expansion Joint are prefered to abosrb movements in the piping system around the heat exchanger while reducing the pressure thrust on the connection.

CLAMSHELL
BELLOWS

Clamshell Repair Bellows provide a very effective solution when a quick and unplanned replacement of the bellows is needed.

En la mayoría de los proyectos, Belman personaliza las juntas de expansión para intercambiadores de calor y el sistema de tuberías que rodea el intercambiador de calor.

MATERIALS

Las juntas de expansión para intercambiadores de calor de Belman pueden diseñarse y fabricarse con todo tipo de materiales. Las juntas de expansión para intercambiadores de calor y el sistema de tuberías que las rodea se fabrican principalmente con acero inoxidable austenítico, así como con aceros de aleación superior, como es el Hastelloy. La elección del material se basa en el medio y el entorno circundante. Los extremos de conexión se fabrican con aceros inoxidables austeníticos o, si se requiere, con acero al carbono con un sistema de recubrimiento específico para el cliente.

ADVANTAGES

Both pressure integrity and service life is achieved
Customised for the operating pressure of the exact application in the Heat Exchanger and the piping system around it
Allow the use of Expansion Joints even in high pressure applications
Cost-efficient solution for high-pressure 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 3^rd 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
