Beat the Heat With Molten Splash Protection

Date: 24/07/25

You may think of metal foundries as a thing of the past, with echoes of the industrial revolution, the heavy machinery of World War Two or the industrial 70s. But metal casting is still a vibrant industry today, both in the UK and around the world.

According to castingthefuture.com, more than 100 million tonnes of castings were produced worldwide last year alone. The UK still has over 400 active foundries across the country, making everything from rail tracks to car parts, manhole covers to marine hulls. Together, these products are worth over £2.2 billion every year.

In addition to this, the UK steel sector still supports over 1,100 businesses and 0.1% of our total economic output. Our six fully operational steel mills produce 5.6 million tonnes of steel every year from Port Talbot and Cardiff, to Rotherham and Scunthorpe.

Molten splash protection

Whether you’re making the metal in a steelworks or casting components at a foundry, working with molten metal is one of the most dangerous jobs around. It only takes the smallest of operator errors to cause molten splash, and in many processes, such as pouring liquid metals into casts, molten splash is an inevitable part of the job, however skilled and experienced your operators may be. 

That’s why it’s essential to protect your machinery and equipment with high quality pipe and cable sleeves that provide molten splash protection as standard. 

Fire Sleeve delivers 

Fire Sleeve, from Sleeve It delivers outstanding molten splash protection, with the ability to withstand molten metal splashes at up to 1200°C. Built for the most demanding of environments, such as steelworks and foundries, Fire Sleeve is designed to operate at continuous temperatures of up to 260°C in between those peaks.

Fire Sleeve is made from texturised bulked 'E' glass fibre yarn, which is knitted into a flexible textile tubular sleeve, and covered with high-grade fire-resistant silicone elastomer rubber. This combination provides full flexibility, without ever compromising on performance. 

For even greater flexibility, Fire Sleeve Hook and Loop can be specified, allowing the unrivalled molten splash protection to be added to systems in-situ, without the need to shut down individual machines, or the production line, in order to disconnect pipes or cables.

Protecting every inch

From the electrical cables that deliver power to your machinery, to the hydraulic hoses that keep it moving, from the intricate control wiring to the essential lubrication hoses, Fire Sleeve can protect every inch of your heavy machinery cables, pipes and hoses, in almost any environment, at the highest of temperatures.

To cover such a broad range of uses, Fire Sleeve is available in a variety of diameters, from 6mm for fine wiring through to 127mm for the widest of ducts and pipework. With more than 25 different sizes to choose from across the range, you can be sure of the perfect fit every time. You can also choose from seven standard colours, with custom colours also available on request for corporate installations or more complex projects.

Whichever size and colour combination you choose, you can count on Fire Sleeve to deliver performance at the highest level, including molten splash protection at the highest temperatures. But you don’t have to take our word for it. 

Fire Sleeve molten splash protection from Sleeve It has been independently tested by leading laboratories to ISO 11925-2 and has been proven to comply with EN 45545-2. It also meets the requirements of IEC 60695-11-10 – classified as HB and V0 – and has a UL94 rating V0, V1, V2c.
