Petroleum hoses are designed to transfer petroleum products i.e. liquid products of petroleum refining process (fuels and oils mainly) but also crude oil and semi-processed petroleum products. Petrochemical products comprise a vast range of products: crude oil, petrol, kerosene, heating oil, diesel oil, hydraulic oil and lubricating oil, hardening oil, machining oils and emulsions, honing oil, thermal oil (heat transfer oil), transformer oil, various types of solvents, maintenance oil, asphalt and asphalt emulsions, other liquid bituminous substances.
The hoses and hose assemblies are used for the extraction and processing of petroleum, transfer, loading and unloading of liquid petroleum products (e.g. oil tankers in ports, tank trucks, rail tankers), oils and fuels distribution as well as refuelling (e.g. petrol pump hoses, heating oil delivery hoses), technological processes in industry, vehicle fuel systems, hydraulic installations, etc.
When selecting the hose, consider the following: its resistance to the specific content of aromatic hydrocarbons in fuel, resistance to special modern fuel additives and oil additives (unleaded fuel, biodegradable fuel, transformer oils) and any special requirements concerning the protection against static charges build-up (copper wire, antistatic rubber, conductive rubber), especially in potentially explosive zones.
Couplings and fittings intended for petroleum hoses (see INDUSTRIAL FITTINGS) should be mounted with worm- drive clamps, bands and bolt clamps or crimped with ferrules using crimping machines.
For more hoses suitable for the transfer of petroleum products, see the following groups: general purpose hoses, chemical hoses, PTFE hoses, TYGON® tubing, composite hoses and steel hoses and in HIGH PRESSURE section.
