Service conditions and performance indexes of corrugated metal hose:

Applicable temperature range: paper tube (PAP)-40℃-150℃; Aluminum tube (APA)-40℃-200℃; Aluminum-coated glass fiber tube-40℃-250℃

Z small bending radius (R): equal to the inner diameter of the hose (D) R = D.

Bending performance: after the pipe is bent to a small radius Z, its diameter change is ≤5%.

Cracking resistance: after 15 cycles of bending, the hose will not break.

Negative rupture pressure: ≥0.06Mpa

Radial pressure resistance: 500N-800N/400MM (varies with the material structure)

Water resistance: the hose is immersed in water for 300h, and the adhesive layers do not delaminate.

Oil resistance: the hose is immersed in 20 # engine oil for 300h, and the adhesive layers do not delaminate.

Expansion and contraction: > 20%
