ESSMANN | Waagen & Automation specializes in the development and manufacture of static and dynamic<\/a> rail scales.
\nESSMANN | Waagen & Automation has developed and successfully commissioned a static HE-GW rail scale<\/a> for loading gas for a major international corporation in the chemical<\/a> industry. <\/p>\n

Customer<\/h3>\n

The client is a group with operations in over 150 countries worldwide and over 30,000 employees.
\nIts core business is the production of paints and coatings.
\nOne division serves the consumer market with decorative paints, another division serves the market for industrial paints, coatings and coating systems. <\/p>\n

Chlorine transportation in Germany<\/h3>\n

In total, around 4.2 million tons of chlorine are produced in Germany every year, mainly at the consumer’s location, and made available via pipelines.
\nNevertheless, it has not yet been possible to establish local production for all major consumers. <\/p>\n

There are also numerous users with very small purchase quantities, such as swimming pools.
\nIn addition, chlorine transportation is necessary both in the event of chlorine production stoppages and short-term peaks in demand. <\/p>\n

Around 6 % of chlorine production is transported by rail; this amounts to around 250,000 tons per year.
\nIn addition, small containers (steel drums with a capacity of up to 1,000 kg and steel cylinders up to 100 kg) are transported, which are mainly delivered by truck to end users such as swimming pools or waterworks.
\nThese transports account for a further approx. 5% of annual chlorine production.
\nThe remaining quantities of chlorine produced are processed in the immediate vicinity of the production facilities or delivered to customers by pipeline. <\/p>\n

The chlorine is transported in liquefied form under high pressure, for which special chlorine tank cars are used, which must meet special safety requirements.
\n VTG AG<\/a> has developed special tank wagons for this purpose.
\nAmong other things, these tank wagons have special buffers with deformation elements, over-buffering protection, roll-over-proof dome covers and a reinforced underframe so that, as a rule, no chlorine can escape even in the event of an accident.
\nIn addition, all openings are located above the maximum liquid level. <\/p>\n

An average chlorine transport by rail consists of 6 – 12 tank wagons, each with a capacity of 60 tons.<\/p>\n

Requirements for loading gas with a rail scale<\/h3>\n

Our customer required a new rail vehicle scale for the safe loading of chlorine gas into tank wagons at its site with existing rail infrastructure.
\nIn order to avoid accidents with chlor<\/a> ine gas, the requirements and rules to be observed when loading harmful chlorine gas are correspondingly high.
\nESSMANN | Waagen & Automation was therefore involved in the project right from the start of the planning and approval phase. <\/p>\n

Technical solution<\/h3>\n

ESSMANN | Waagen & Automation used its extensive knowledge from many projects with rail scales<\/a> to provide the customer with intensive advice and together they developed and elaborated a technical solution consisting of the static HE-GW 15 rail scale<\/a> with a length of 15 m.<\/p>\n

In this case, the weighbridge foundation is not produced as a precast concrete element, as a special safety enclosure for the loading of chlorine gas is being built around the weighbridge.
\nFor this reason, an in-situ concrete foundation is being developed, which will serve as a foundation for both the weighbridge and the loading hall. <\/p>\n

The track scale has the following key figures:<\/p>\n
