Hoses Cannot Take Excessive Abuse

Chemical hoses must be designed for a specific service. Hoses are required to convey compressed gases, slurries, petroleum products, solvents, bulk chemicals, such as acids and 

Hoses built to United States standards have a four-to-one pressure design safety factor. This means that the maximum allowable working pressure (MAWP) must be one-fourth the hose s minimum burst pressure. This rating is generally specified at 72°F, and many users are unaware that, as the operating temperature increases, the hose assembly s MAWP decreases. [11]
