Product description
Two types of thermoplastic multi-layer hose assemblies for carrying liquefied petroleum gas (Type 1)
and liquefied natural gas (Type 2) with the following construction:
• Class A (for onshore applications):
- An internal wire helix of stainless steel confirming to 1.4401 from EN 10088-3
- A multi-ply wall of layers of films and fabrics made of thermoplastics to provide a complete
seal
- An external wire helix if stainless stell confirming to 1.4401 from EN 10088-3
• Class B (for offshore applications):
- An internal wire helix of stainless steel confirming to 1.4401 from EN 10088-3
- A multi-ply wall of layers of films and fabrics made of thermoplastics to provide a complete
seal
- An external wire helix if stainless stell confirming to 1.4401 from EN 10088-3
End fittings & metallic ferrules are made of:
- stainless steel 1.4401 from EN 10088-3 for both type 1 & type 2 hoses
Application/Limitation
Pressure/temperature details:
| Pressure/ temperature | Class A | Class B | Class A | Class B |
| Type 1 | Type 1 | Type 2 | Type 2 | |
| Maximum working pressure (bar) | 25 | 20 | 13 | 10,5 |
| Proof pressure (bar) | 37,5 | 30 | 19,5 | 15,8 |

For all types of end fittings, that part of the fitting that enters the hose and forms the means by which
the fitting is connected to the hose shall be provided with scrolls or protrusions on the surface that
correspond to the pitch of the internal helix wire of the hose.
When assembled to a hose there shall be electrical continuity between the end fitting and the internal
and external wires.
Routine tests shall be carried out on each hose assembly and in accordance with Annex G of EN
13766:2010.

Description
gassoflex lPg is a hose designed with the
combination of multilayer of different polymers
and spirals in stainless steel 316l with the latest
manufacturing technology that makes it an
excellent and safe solution to support cryogenic
products at extreme temperatures up to -196ºc
and working pressures up to 10,5Bar.In typical
applications such as liquefied natural gas
discharge loading both on trucks, wagons and
even marine applications.
gassoflex lNg is a hose designed with the
