Working pressure – 10 bar (1,0 MPa)
Burst Pressure – 30 bar (3,0 MPa)
Flame retardant – afterflame and afterglow max. 5 seconds
Antistatic resistance <2×106 Ω
Safety factor 3:1 according to EN ISO 1403
These flame retardant and antistatic hoses for water meet the requirements of mining industry for use in machinery and equipment working in difficult underground conditions.
These hoses are designed for use in areas with methane or coal dust explosion hazard.
They are resistant to weathering, ozone and heat. If they are meant to be used for mixture of water with sand or other abrasive materials they can be produced in version with increased resistance to abrasion.
The properties of these hoses are confirmed by independent laboratory that:
– certified the hoses for compliance with European standards EN ISO 1403,
– issued the right to use the Polish Safety Mark B that confirms the use of hoses in coal mines in methane and non-methane fields with A-, B- and C- level methane explosion hazard and A- and B- level coal dust explosion hazard.
On request, we provide additional spiral steel wrap for protection against excessive abrasion and deformation, such as kinking or crushing. This option applies to hoses with nominal diameters larger than DN 12.
From -25°C to +100°C or from -40°C to +100°C for hoses with extended operating temperature range.
According to EN ISO 1403.
The rubber compounds, from which the hoses are produced, have parameters that meet the requirements of the American MSHA standard.
Antistatic synthetic rubber with normal or increased resistance to abrasion depending on the version.
Interlayers made of textile cord or synthetic threads depending on the inner diameter.
Flame retardant, antistatic, black synthetic rubber resistant to abrasion, weathering and ozone.
METHOD OF MARKING
These hoses are marked with a convex inscription containing the “TA” sign referring to “flame retardant and antistatic” and reference to the standards EN ISO 1403. Smaller diameters may be marked with white print.
