This product is suitable for fracturing water supply during shale oil and gas extraction, oil transportation, coal mine emergency drainage, emergency drainage, urban emergency drainage, agricultural water supply and irrigation, industrial wastewater transportation, fire remote water supply and other industries.
Product Description
- Structure: The middle braided layer of the hose is made of high-strength polyester filament, and the inner and outer rubber layers are made of polyurethane material extruded in one go.
- Features: Wear resistance, acid and alkali resistance, oil resistance, corrosion resistance, aging resistance, will not harden, become brittle and break in cold environments; ultra-large diameter, ultra-large flow, easy connection, shrinkage It is quick to put and is an alternative to metal pipes.
- Applicable temperature: -40℃～70℃.

Advantage:
UV resistance: Observed under a 2x magnifying glass, there are no cracks in the outer rubber layer of the hose.
Ozone resistance: Under the conditions of ozone concentration of 50×10 and test temperature of 40℃±2℃, after 72 hours, there is no crack in the outer rubber layer of the hose when observed with a 7x magnifying glass.
Wear resistance: Using H-22 grinding wheel, without additional pressure, the number of grinding wheel revolutions when the reinforcement layer is exposed is not less than 250,000 revolutions
Static conductive performance: The oil delivery hose is woven with continuously conductive static conductive wires. The static conductive wire ensures that there is continuity between the two joints of the hose, and its maximum resistance value is not greater than 50/s. When the hose is coiled, folded, and subjected to the internal pressure specified in the specification, the hose is guaranteed to be conductive at all times.
Applicable temperature: When used under the conditions of -40℃~70℃, the hose should have no cracks, adhesion, etc., and the oil delivery hose should always be connected.
Anti-oil pollution: When the hose is used to transport oil materials whose colloid content needs to be controlled, the test fluid after filling with liquid will be clear and translucent, with no impurities such as suspended solids. After the test, the detergent colloid content of the test solution shall not be greater than 6mg/100ml.
Waterproof and pollution resistance: Meet the safety evaluation standard requirements of GB/T17219.
Application
Application scope: Petroleum, chemical industry, shipbuilding, agriculture, water conservancy, mine rescue, fire protection and other fields. It is an ideal tool for long-distance and large-flow liquid or gas transportation.
