1 Rubber steam hoses & couplings know-how makes the difference

2 STEAM, A CRITICAL UTILITY Steam is critical in many operational processes. However, working with steam is dangerous. Selecting the right hose, couplings and installation method is important to be able to work safely with steam.

STEAM: A CRITICAL UTILITY! Popcorning effect The service life of steam hoses is drastically reduced when the condensation is not drained from the hose after use.

As a result, the hose poses an immediate danger to users in its vicinity.

3 STEAM: A CRITICAL UTILITY! Popcorning effect The service life of steam hoses is drastically reduced when the condensation is not drained from the hose after use. This condensation or vapour penetrates the pores of the inner wall of the hose and is retained. The next time the hose is connected to the steam network, the retained moisture in the inner wall expands by a factor of 1600; because of this sudden increase in volume, air bubbles are created in the inner wall that blow rubber particles from the wall. Danger to the user Rubber steam hoses, which are affected on the inside by popcorning, often display no damage on the outside. As a result, the hose poses an immediate danger to users in its vicinity. The damaged braid, which is invisible from the outside, can no longer withstand the operating pressure, which causes the hose to burst. The clamp connection can no longer grip the coupling and the connection detaches from the hose. This can result in serious injury or even death to operatives as well as major damage to installations. Expansion factor water-steam Cracked hose affected by damaged inlays 1x 1600 x The surface of the inner wall will resemble popcorn. Every time the hose is used, at start-up the popcorning effect is exacerbated with particles of rubber being ejected from the inner wall of the hose. These particles will contaminate the steam network or the product and block the system. The moist vapour, which is found in the rubber of the hose, will also force its way outwards and degrade and weaken the steel braid of the hose.

Steam graph By displaying the combination of operating pressure and temperature, the steam diagram 225 shows whether the steam is saturated or superheated.

The area above the line represents superheated steam. The service life of steam hoses is shortened every time the hose is exposed to superheated steam.

4 Steam graph By displaying the combination of operating pressure and temperature, the steam diagram 225 shows whether the steam is saturated or superheated. Saturated steam can either contain or be free of unevaporated water particles and consequently be either wet or dry. The area below the saturated steam line represents hot water. The area above the line represents superheated steam. The service life of steam hoses is shortened every time the hose is exposed to superheated steam. Temperature (C ) Superheated steam Saturated steam Hot water Saturated and, to a certain extent, wet steam has a lubricating effect on the rubber inner wall of the hose. However, superheated and therefore dry steam slowly hardens the 0 3,5 7,0 10,5 14, ,0 Manometer pressure (bar) rubber inner wall due to the process of vulcanisation. The result is a reduction in the service life of the rubber. Superheated steam can sometimes be created unintentionally when the operating pressure is suddenly reduced, for example when a valve is suddenly opened or at a transition from a small to a much larger diameter pipe.

5 THE HIGHEST QUALITY STEAM HOSE BR8 INFERNO Exceeds the EN ISO A norm In the last 20 years, GOODALL, our manufacturer, has carried out extensive research into rubber steam hoses. Not only have the rubber compounds used for the inner wall and outer cover been continually improved, the material and coating of the steel inserts has also received considerable attention during the development of the GOODALL rubber steam hoses. Standard steam hose Manufacturer X Practical tests and test procedures, which approximate the most extreme applications for rubber steam hoses, have taught GOODALL much about the medium of steam and what defines the ultimate steam hose. Appearance of popcorning Even a special EPDM compound still has a porous structure that allows microscopically small water and steam particles to collect in the wall and cause the popcorning effect. See photos on this page. For the inner wall of the GOODALL BR8 INFERNO steam hose, GOODALL developed a special, impermeable rubber compound, which when extruded is extremely smooth. After a few weeks After the test phase INFERNO BR8 steam hose Service life Extensive tests of the GOODALL BR8 INFERNO confirm that this hose has an extremely long service life, sometimes more than three times as long as other hoses. The use of rubber steam hoses offers advantages over the often-used stainless steel hoses. For example, rubber steam hoses are less susceptible to buckling, have a chemically resistant outer cover, are less vulnerable to external damage and can therefore be quickly repaired and retested on site. After a few weeks After the test phase After the Test phase: No sign of popcorning

SAFE USE Steam is extremely dangerous. You should therefore choose both a safe coupling and a safe method of installation.

All LMC-Couplings for steam applications comply with EN ISO 14423 and have a special, strong serrated hose tail that has a safety collar.

Testing pressure: 90 bar Burst pressure > 180 bar The long, robust safety clamps, which also comply with EN ISO 14423, guarantee the safety of the connection.
