Profile :
Hoses with parallel waves (profile omega)

Material :
Stainless austenitic steel, conforms to the requirements of DIN standard 17440 X 10CrNiMoTi 1810, reference of material: 1.4301 (AISI 316 Ti).

Braiding :
Stainless steel wire, conforms to the requirements of DIN standard 17440 X 5CrNi 189, reference of material: 1.4301 (AISI 304).

Connections :
Threaded supports, connections, ends.

Dimensions :
150 mm maximum nominal diameter

Pressures :
150 Bar maximum

The pressures which appear in the table depend on the nominal diameter, the temperature, the number of braids etc.

Amplitude of temperature :
-196°C- +600°C

Applications :

Distribution of gas liquid under pressure and vacuum. Realized starting from stainless steel, this type of pipes can be used in the installations containing of the fluids and corrosive gases. Shim elements, they are used of absorbtion in the event of displacements, dilation thermics, and compensation in the event of misalignment of rigid tubes (drains).

The applications which require a more important flexibility.

The operating pressure (Pr), quoted in the table, is the allowed pressure operating maximum at the ambient temperature.

The allowed pressure operating maximum at the temperatures, higher than the ambient temperature, is calculated according to the following formula:

Prt = Pt X kt (bar)

Example:

For pipes with only one braid, with diameter DN 50, intended for the distribution of fluids with stable flow, operative at the temperature of 150°C and in the absence of vibrations, the allowed pressure operating maximum is calculated as follows:

Prt = 25 X 0.8 = 20 bars

Order :
During the ordering, please quote : the type of pipes, the diameter nominal (LN), operating pressure, distributed fluid, the type, size and the material of the connections.
