Steam hoses

What are the types of steam hoses?

There are two types of steam hoses according to the ISO 6134 classification:

• low-pressure steam hoses - its corresponding operating temperature is 164 degrees Celsius, while the maximum working pressure is equal to 6 bar; 
• high-pressure steam hoses - in this case, the relevant operating temperature is 210 degrees Celsius, while the maximum working pressure is 18 bar.

In addition to the above division, there is another distinction, as both low and high-pressure steam hoses come in two types.

The first of these is oil-resistant steam hoses. They are distinguished by their high operating temperature, which reaches up to 207 degrees Celsius for saturated steam and 232 degrees Celsius for superheated steam.

In addition to these, you have non-oil-resistant steam hoses. They are used for more general applications and usually have a longer service life compared to oil-resistant versions. Unfortunately, their disadvantage is that they are easily damaged when in contact with oil or excessive heat.

Their walls soften and swell, leading to rupture over time.

This is why the right choice of steam hoses is so important. Especially when working with steam, which poses a very high risk to health and life.

Are steam hoses safe?

Yes, steam hoses are safe when used correctly. Steam hoses are key when it comes to ensuring adequate safety during work. That is why we keep the highest standards in our range when it comes to the workmanship of both steam hoses and steam fittings.

The industrial steam hoses that you will find in the range are exclusively from reputable manufacturers.  Each of these companies has been producing reliable and fully functional steam hoses for many years.

Steam is a very dangerous industrial medium. That is why we go to great lengths to ensure that the quality of our range reduces the risk of failure and burns.

What risks should be taken into account while working with steam hoses?

There are 3 main risks that should be taken into account while working with steam hoses:

• vulcanization - superheated steam is characterized by high temperatures and dryness, which can lead to the hardening of the inner layer of rubber, resulting in a shorter service life; 
• popcorning - this phenomenon originates from water that has been trapped in the inner layer of the steam hose after operation. When heated again, the water drops expand, leading to the formation of bubbles inside the hose. One of the ways to prevent this is to dry the hoses after work or to use special varieties; 
• corrosion of steel inserts - steel braids are in constant contact with steam, so there is a risk of corrosion, which leads to weakening and, ultimately, rupture of the hose. However, such a situation can easily be avoided. Simply invest in hoses with braided galvanized steel.

Even the highest quality steam hose and pipe from our range can pose a risk if you do not use them as intended.
