The R12 hose is a four-layer steel wire helically reinforced hydraulic hose, conforming to the 100R12 type in the SAE J517 standard and corresponding to the R12 type hose in the ISO 3862:2020 standard. Here is a brief introduction to it:
The R12 hose consists of an inner rubber layer, four layers of steel wire helical reinforcing layers and an outer rubber layer. The inner rubber layer is generally made of nitrile rubber (NBR), which has good oil resistance and chemical compatibility. The reinforcing layer is made of four layers of high-strength steel wire spirally wound, enabling it to withstand high pressure and high pulses. The outer rubber layer is usually made of chloroprene rubber (CR) or ethylene propylene diene monomer (EPDM), which has the properties of wear resistance, ozone resistance and UV resistance.
R12 hose is widely used in various occasions that require high-pressure hydraulic transmission, such as excavators and cranes in construction machinery, hydraulic supports and rock drilling jumbos in mining machinery, and injection molding machines in industrial equipment, etc.
Construction machinery field (Core application scenarios)
The key hydraulic circuits suitable for various heavy engineering equipment need to withstand frequent high-pressure pulses and complex outdoor environments
Excavating machinery: The boom, bucket arm, and bucket cylinder pipelines of excavators ensure high-pressure power transmission for excavation and lifting actions.
Lifting machinery: Luffing cylinders, telescopic boom cylinders, and rotary motor pipelines for truck cranes and crawler cranes, supporting the lifting of heavy objects and the adjustment of their postures.
Mining and Metallurgy Field (Extreme Working Conditions Adaptation)
To ensure the stable operation of heavy equipment in harsh environments with high dust, strong impact and high pressure:
Mining equipment: Hydraulic breaker hammer pipelines for mining excavators and rock drilling jumpers (withstanding instantaneous high-pressure impact), columns and jack pipelines for hydraulic supports (supporting the mine roof and requiring continuous high-pressure stability);
