High-Flexible (Type HFA and Type HF)

Corrugated ring hose made of stainless steel Type HFA and Type HF

Description

Type HFA –> Material: AISI 316L

Type HF –> Material: AISI 316Ti

Application

• Ideal for conducting liquid and gaseous media as well as acids and lyes*
• All applications which require the smallest possible bending radius and our hose type “Standard” cannot be deployed due to its larger bending radius
• This type is also particularly recommended for use as a double hose line

Hose design

• Tight corrugated Full metal hose made of butt welded pipe
• Hose can be provided with no, one or two stainless steel braiding
• Production according EN / ISO 10380

Material

• Hose standard: AISI 316L, AISI 316Ti
• Braid standard: AISI 304

Temperature

• From- 196°C up to max. + 600°C

Also possible

• With DVGW acceptance
• CE sign as per the pressure equipment directive (97/23/EC)
• As per DIN 2827
• With external Agraff or spirals to protect against abrasion
• With internal Agraff hose or braiding as flow conductor
• With flanged recoil lock
• With PTFE inner lining
• Special designs at customer request
