GOST 5398-76 Pressure Suction And Discharge Hose

Detailed Product Description Suction water, oil, acid/alkli and sand hoses. ID from 25mm to 250mm. PRESSURE-ABSORBING RUBBER HOSES, NOT REINFORCED, WITH TEXTILE SKELETON, GOST 5398-76. Hoses with textile skeleton; Metal spiral have the soft cuffs at the ends for joining to armature.

GOST 5398-76 Hose pressure-suction with a textile frame and a metal spiral, unreinforced. Suitable for suction and delivery of various liquids, fuels, petroleum-based oils and gases. Two groups of hoses are made, depending on the operating conditions:
Group 1 - Suction,
Group 2 - Pressure-suction.
Sleeves are divided into classes, depending on the purpose and working environment:
- Gasolines, diesel fuel, oils for petroleum. basis, B(A) - antistatic design;
- Technical water;
- Gas, air;
- weak solutions of acids and alkalis (concentration up to 20%).
Symbol example: Sleeve B-2-25-10 HL GOST 5398-76, where
- hose class corresponding to the working environment (Gasoline);
2 - sleeve group (Pressure-suction);
25 - inner diameter (mm);
10 - working pressure in kgf/cm2 (10 kgf/cm2 = 1 MPa); - climatic design for areas with a cold climate.
Hoses meet ISO 1823-75 International Standard except stretch at hydraulic pressure and strength at ozone influence definitions.
