Q) What is hose bend radius?

A) The bend radius of a hose is a relevant factor in hose selection when an application requires significant curves and flexibility. The bend radius is measured as the distance to the inside edge of the hose when making a 90° bend. When bent at too sharp an angle, the reinforcement may be unduly stressed or distorted, thereby shortening the hose life. A hose assembly should not be bent beyond its minimum bend radius to fulfill an application.

Q) What is a chemical hose pressure rating?

A) A chemical hose pressure rating is the maximum amount of pressure a hose can tolerate in standard working conditions. High temperature, and other extreme environments, can cause the chemical hose pressure rating to decrease. See our hose performance derating chart >>

The pressure rating of hose fittings should also be considered when constructing a hose assembly for a specific application.

 

Q) When should you evaluate the chemical hose material being used in an application?

A) For almost every application there is a best material to use. 

 

Q) What hose is best for acid transfer?

A) Acid transfer can be one of the most corrosive medias for a chemical hose. Depending on the degree of acidity, temperature, pressure and variety of other factors, UHMPWE or Teflon lined PTFE hose assemblies provide strong resistance.

Q) Which hoses provide the best abrasion resistance?

A) Abrasion resistance for chemical hoses can refer to a variety of characteristics. For example, a hose with a standard EPDM cover can be adequate for static applications. For applications where hoses are subjected to external abrasion, we offer several external protective options that can be applied to any chemical hose selected.

 

Q) What hose material is temperature resistant?

A) Chemical hose selection should be approached carefully when elevated temperatures are involved. As a rule, any application over 130F should be evaluated by one of our chemical hose specialists. We can provide solutions for almost any elevated temperature application, including metal hose solutions that can perform in temperatures as high as 1300F.

 

Q) Can a hose maintain its maximum pressure rating in any environment?

A) No, a hose assembly’s maximum pressure rating assumes certain conditions like normal working temperature or standard corrosiveness of media being conveyed. In instances where a hose assembly will be used continuously for a high temperature or highly corrosive application, please consult the hose performance derating chart or chat with one of our experts.

 

Q) When should a metal hose be used instead of a rubber one?

A) See our page on metal hoses for the factors to consider when deciding on a metal hose

Q) What type of gasket should be used in the fittings of a chemical hose assembly

A) We offer a number of gasket options that can be tailored to your unique application. The standard buna gasket supplied by camlock manufacturers is suitable for petroleum applications, but should not be used with aggressive chemicals. Options include Viton, EPDM, and Teflon encapsulated options.

 

Q) I don’t see the fittings I need on your website; do you have any other options?

A) Yes, we make thousands of combinations of various hose assemblies with fitting end pairs. If you don’t see exactly what you need just ask. Odds are we can make it, and probably have before.
