As steam hose season approaches and you inspect or replace the products that you have in place, your industrial hose supplier should be aware that tube erosion (typically called the popcorning) in steam hose is most pronounced in hoses on the market which have an inner liner of EPDM rubber. Tube erosion will destroy a steam hose and can damage the steam network. It’s also what injures dozens of workers each year when a hose product fails.Popcorning destroys steam hose from within and the effect occurs when microscopic water particles collect in the wall of a hose.
When new steam enters the hose it heats up those particles, which expand explosively to 1600x their size.
When that happens, popcorn-like blisters explode on the hose’s inner surface. The resulting particles of rubber can contaminate the steam network or the product.
Over time, moisture forces its way out towards the skin of the hose, weakening the steel braiding and making it unsafe for use.
GOODALL® steam hose products use EPDM on the outside for its outstanding ozone, weather and abrasion resistance properties. For the inside, they have developed a proprietary Chlorobutyl compound that is fifteen times less permeable to vapor and other gases than EPDM. The lower the permeability, the longer the hose life, the greater the safety. Building on the superior proprietary compounds, the Inferno ISO 6134-2A steam hose product is braided with zinc-plated wire, which:
- Increases the corrosion resistance by 3x, verified with aggressive salt spray testing
- Manages risk with increased product and operator safety
- Decreases liability
