Flexible Hoses

DEKOMTE stainless steel corrugated hoses are high-grade, highly flexible and impermeable structural elements for piping technology. They easily satisfy the requirements for this technology with regard to resistance to pressure, vacuum tightness, temperature stability, resistance to corrosion, flexibility and durability.

Application of Flexible Hoses

DEKOMTE stainless steel corrugated hoses are universally applicable for practically all fluid and gaseous media as well as pumpable solid substances, if necessary using a PTFE liner as protection against especially aggressive media or to attain a non-adhesive inner wall (DEKOMTE PTFE chemical tubes). 

Characteristics of Flexible Hoses

They accommodate expansion and movement, serve as a flexible connection between mobile and static elements of mechanical equipment, neutralise of vibrations, equalize unavoidable assembly tolerances. They are used as extinguishing and loading hoses, as fuel hoses, etc.

For protection against mechanical influences, for example impermissible buckling and abrasion, we supply our stainless steel corrugated hoses with external or internal protective a graffe hose made of stainless steel.
For protection against contact or for danger-free handling we equip our stainless steel corrugated hoses with external thermal insulation. DEKOMTE stainless steel corrugated hoses are used in all temperature ranges from - 196°C to +600°C, and from a high vacuum up to a pressure of 200 bar.
