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
