Technical Data
SILVER/2 A304 – 321 – 316
TRECCIA A304
Inox SILVER/1 and SILVER/2 hoses are at the top of a range of products studied for the fluids crossing.
The structure, completely in stainless steel, allow to have a very good heat resistance (up to +700°C) and a very strong acids resistance.
The available inside diameter is from 6 to 250 mm; these hoses can be used to all the needs of the different indus- trial fields.
The flexible hoses INOX SILVER can be welded to a lot of fit- tings and flanges available on the market, satisfying every customer request.
