Although this phenomenon is well known in theory, it has very real implications for day-to-day operations, particularly when temperatures remain above 30\u201335\u00b0C for prolonged periods and the vehicle is exposed to direct sunlight or waiting in logistics areas.<\/p>\n
In the transport of chemical liquids, where safety and precision are critical, understanding this behaviour is not optional but essential.<\/p>\n
<\/p>\n
<\/p>\n
Thermal expansion is the tendency of liquids to increase in volume as their temperature rises.<\/p>\n
At a molecular level, an increase in temperature causes particles to move faster and occupy more space, reducing the density of the product.<\/p>\n
Although this change may appear small, it can have a significant impact when dealing with large volumes, such as those transported in tankers.<\/p>\n
<\/p>\n
<\/p>\n
Under normal conditions, the product is loaded with a safety margin to allow for thermal expansion. However, in extreme heat conditions, situations such as the following may occur:<\/p>\n
This behaviour is particularly relevant when:<\/p>\n
<\/p>\n
1. Direct solar radiation on the tanker:<\/strong> The steel tank absorbs heat quickly, increasing the temperature of the product even when the vehicle is stationary.<\/p>\n 2. Road surface temperature:<\/strong> Heat reflected from the ground can considerably increase the temperature of the vehicle as a whole.<\/p>\n 3. Duration of exposure:<\/strong> A short temperature peak is not the same as several hours of continuous exposure.<\/p>\n 4. Type of product being transported:<\/strong> Each liquid has a different coefficient of thermal expansion. More volatile or lighter products are particularly sensitive.<\/p>\n <\/p>\n Although thermal expansion is a physical phenomenon, its consequences are very practical:<\/p>\n \u2022 Filling management<\/strong><\/p>\n Loading without taking thermal expansion into account can reduce the available safety margin and increase operational risk.<\/p>\n \u2022 Internal tank pressure<\/strong><\/p>\n The increase in volume can lead to higher pressure levels that need to be controlled through appropriate ventilation and safety systems.<\/p>\n \u2022 Unloading behaviour<\/strong><\/p>\n Temperature differences between the point of origin and the destination can cause variations in the apparent volume of the product.<\/p>\n \u2022 Safety during prolonged stops<\/strong><\/p>\n Unshaded parking areas can become critical points during heatwaves.<\/p>\n <\/p>\n In professional tanker transport, managing thermal expansion requires a combination of planning, technical measures and monitoring:<\/p>\n \u2714 Control of filling levels<\/strong><\/p>\n Always respect the expansion margins established according to the applicable regulations and the type of product.<\/p>\n \u2714 Avoid prolonged exposure<\/strong><\/p>\n Whenever possible, park in shaded or well-ventilated areas.<\/p>\n \u2714 Pressure monitoring<\/strong><\/p>\n For sensitive products, monitoring internal pressure is essential during transport and while stationary.<\/p>\n \u2714 Route and time planning<\/strong><\/p>\n Minimise unnecessary waiting times in high temperatures.<\/p>\n \u2714 Staff training<\/strong><\/p>\n Understanding how the product behaves is essential for anticipating potential incidents.<\/p>\n Thermal expansion is an unavoidable phenomenon, but it can be effectively managed when transporting liquids by tanker.<\/p>\n Its impact during summer can be significant if its effects on volume, pressure and product behaviour are not taken into account.<\/p>\n If you would like more information about our dangerous goods transport services or any of the solutions we offer, please do not hesitate to\u00a0contact us.<\/a><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" During the summer months, the transport of liquids by tanker truck faces an unavoidable but often underestimated physical factor: the thermal expansion of the product.<\/p>\n","protected":false},"author":1,"featured_media":260649,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"How Does Thermal Expansion Affect the Product in a Tanker During Heatwaves?","_seopress_titles_desc":"During the summer months, the transport of liquids by tanker truck faces an unavoidable but often underestimated physical factor: the thermal expansion of the product.","_seopress_robots_index":"","_et_pb_use_builder":"on","_et_pb_old_content":"\u00a0<\/h2>\n

Good Practices to Minimise Risks<\/h3>\n
La crisis de los conductores de mercanc\u00edas: el reto inminente del transporte<\/h1>\r\nLos transportistas de mercanc\u00edas tienen un papel clave, ya que son los encargados de garantizar el transporte de bienes y productos necesarios para mantener un correcto funcionamiento de las distintas cadenas de suministros. Este proceso a su vez es esencial para la econom\u00eda del pa\u00eds, ya que asegura el abastecimiento de las empresas y su capacidad para generar empleo e ingresos.\u00a0 <\/span>A pesar de su importancia, esta profesi\u00f3n parece estar en peligro de extinci\u00f3n y esta situaci\u00f3n no parece generar suficiente alarma entre las autoridades pertinentes.<\/span>\r\n\r\n\u00bfSab\u00edas que s\u00f3lo el 6% de los conductores que trabajan en el sector europeo del transporte de mercanc\u00edas por carretera son j\u00f3venes?<\/b>\r\n\r\nEsta cifra resulta muy alarmante <\/span>y es importante que se tomen medidas inmediatas para evitar que la situaci\u00f3n empeore a\u00fan m\u00e1s.<\/span>\r\n\r\nEn Espa\u00f1a se presenta una situaci\u00f3n similar, el 70% de los transportistas tienen m\u00e1s de 50 a\u00f1os. La brecha existente entre los conductores que se jubilan y los transportistas nuevos que se incorporan en esta profesi\u00f3n sigue aumentando y se espera que esta situaci\u00f3n se triplique en toda Europa. Actualmente, se estima que se necesita contratar a medio mill\u00f3n de conductores, y se prev\u00e9 que la tasa de puestos vacantes para transportistas aumente hasta superar el 60% para el a\u00f1o 2026.<\/span>\r\n\r\nEl problema de la falta de conductores de camiones, que ahora se ha convertido en una emergencia, comienza a ser una preocupaci\u00f3n para los 27 pa\u00edses miembros de la Uni\u00f3n Europea, gracias a las organizaciones del sector que han llamado la atenci\u00f3n sobre ello. En respuesta, la Comisi\u00f3n Europea ha propuesto adelantar la edad m\u00ednima para obtener la licencia de conducir C para veh\u00edculos pesados a los 17 a\u00f1os, permitiendo que los j\u00f3venes conduzcan bajo supervisi\u00f3n hasta los 18 a\u00f1os. Aunque esta medida podr\u00eda ayudar en la actual crisis de falta de conductores, no ser\u00e1 suficiente para solucionar el problema por s\u00ed solo. Adem\u00e1s, en muchos pa\u00edses de la UE se requiere tener m\u00e1s de 21 a\u00f1os para conducir un cami\u00f3n, y en algunos casos incluso m\u00e1s de 24 a\u00f1os.<\/span>\r\n\r\n\u00a0\r\n\r\n\u00bfCu\u00e1l es la titulaci\u00f3n requerida para convertirse en conductor o conductora de un tr\u00e1iler?<\/b>\u00a0<\/span>\r\n\r\n\u00a0\r\n
