Stainless metal bellow hose with braid

Application:

Medium Duty steel bellow hose suitable for very high temperatures and pressures. Typically used in connection with hot water or other supply installations.

Construction:

Flexible corrugated stainless steel bellow hose suitable for extreme temperatures and pressures. On the outside, the hose is protected with AISI 304L or 316 stainless steel braid. On the inside the hose is made of corrugated AISI 316 or AISI 321L stainless steel. On the outside, the hose can be covered with silicone for higher hygienic surface, as well as protection from heat up to +200°C. The hose can be supplied with couplings in several standards such as BSP and hygienic couplings.

Technical specifications

Pressure: 

All pressures are stated at the temperature +20°C.

Flexible bellows hoses operate effectively within a temperature range that extends from -273°C to +600°C. This operating range is affected by the materials used for fittings and the welding methods used. The WPD values vary with temperature changes, as described in the table below.

Example: If the working pressure is specified as 100 bar at +20°C, then the working pressure at +250°C will be 65 bar.

Standards:

European ISO 10380 Standard, ISO 9001/2000, and Directive 2014/68/EU.

Safety factor:

Safety factor: ≥ 4 times working pressure.
