HYDROFORMED STAINLESS STEEL EXTRA-FLEXIBLE HOSE WITH DOUBLE WALL AND NARROW PITCH

Parflex®

CHARACTERISTICS:
Excellent reliability and flexibility, resistant to corrosion and static/pulsating pressure, absence of permeability, excellent absorption of high-magnitude vibrations.
Solution for overcoming all problems related to dynamic offsets or cyclic motions.

 

 

PROFILE:

High corrugation, narrow pitch, double wall.

 

 

MATERIALS:
Stainless steel 1.4541 EN10028-7 (AISI 321)
On request, other grades of St. St.

 

CONSTRUCTION:
Hydroforming of a double-walled longitudinally butt-welded tube.

FITTINGS:
In any material or type by TIG welding or silver brazing.
Braid ferrules available for optimal attachment of end connectors.

USE:
Delivery under pressure, depression, or vacuum of all liquid or gaseous fluids compatible with stainless steel under severe environmental conditions, combined with aggressive chemicals, high temperature, high pressure, extremely frequent movements, static or dynamic offsets, strong vibrations.

 

 

APPLICATIONS:

Cryogenic and technical gasses, refrigeration and air bleeding on aircraft, oil breather on automotive engines, compressors, plate presses

 

 

TEMPERATURE:
-200° ÷ 550°C
For a temperature range 50° ÷ 550°C working pressure must be reduced by applying the relevant coefficients (See document B205 Derating factors”).
For a temperature range higher than 550°C, please contact our Technical Department.
