Corrosion in flexible metal hoses and expansion joints

11 June 2019

In this week’s article, ‘Corrosion considerations for flexible metal hoses and expansion joints’, Frank Caprio, Corporate Trainer at Hose Master, discusses how there are many industrial applications requiring flexible hoses and expansion joints, where the service conditions preclude the use of rubber, plastic, composite, or other non-metallic materials of construction. In these applications, flexible piping components can be made using various metal alloys, which provide exceptional service life and value.

“Selecting the best alloy for any application depends not only on the cost effectiveness of the alloy and the ability to form and fabricate that alloy into a finished product, but also the sustainability of the alloy to accommodate the variables of the intended application,” Caprio explains. “Extremely temperatures or pressures, fire safety, resistance to permeation of media, or flexibility requirements are some of the reasons why metal hoses and expansion joints may be preferred. Additionally, one key application variable that must be considered is the ability of the alloy to resist corrosion. This article will discuss important factors to consider when determining the best alloy for a potentially corrosive application.”
