(3)Mainly insist on high impact toughness and plasticity, and use high temperature tempering when there is sufficient strength. Generally, steel should be prevented from tempering between 230 – 280 degrees and stainless steel between 400 – 450 degrees, because a tempering brittleness occurs at this time.
Temperature range and various oils applicable to various rubbers Silicone rubber has outstanding resistance to oil at high temperatures. Among common organic rubbers, nitrile rubber and chloroprene rubber have somewhat higher oil resistance at temperatures below 100°C, but at higher temperatures silicone rubber is superior.

31/10/2016· If high fluid temperature poses a problem, redesign the circuit so it is more efficient or install a heat exchanger to reduce fluid temperature. At any rate, experts recommend that hose asselies exposed to high-temperature conditions should be inspected frequently for any signs of deterioration, and damaged asselies should be immediately replaced with ones with a higher …
ARLANXEO''s HNBR products, summarized under the Therban® brand, offer excellent properties wherever high temperature and fluid resistance is needed. The polarity of HNBR is directly influenced by the ACN content. Higher ACN increases the polymer''s polarity and, therefore, resistance in non-polar media like oil, grease, fat, and fuels.

High Temp. 2 wire hose High pressure hose for hydraulic fluids and aqueous emulsions and water As above but high temperature rubber formulation. Blue cover 22 HT2 Two wire braid High pressure hose for hydraulic fluids, aqueous emulsions, water and air Similar to R2AT but has increased flexibility, high temperature and also conveys air 23 JH70 Jacking Hose
HVAC Hoses: Ageing Test Done for High-Temperature Silicone Hoses. With the EURO-VI regulations, the working temperatures and pressures for Coolant Hoses have become very demanding. To resist these rising under-the-hood working parameters, HVAC system providers are moving to Silicone Hoses, instead of the erstwhile popular EPDM Hoses.
ASTM D3045. ASTM D3045 is a standard practice for heat aging of plastics without load. It tests the exposure conditions to which plastics should be exposed to test their resistance to oxidation or other types of degradation occurring over time. Exposure to higher temperatures than the intended use temperature for extended periods of time causes
A highlight in MFX products portfolio is the HCR Special Hoses line (High Collapse Resistance). These hoses are built with a metalic carcass made out of stainless steel or other alloys and are capable to operate in water depths up to 3,000 meters. The MFX portfolio also includes HTR (High Temperature Resistance) hoses.
Ralco offer a complete range of hose, tubing, clip hoses and flexible ducting hoses for many high temperature appliions. We As an overview, we can supply rubber hoses with working temperatures up to +235 and flexible ducting hose up to +1100. Our range of high temperature hoses include EPDM lined hose with working temperature up to +235.
1/4/2014· Here, it should be noted that ZDMA has a good aging resistance at low temperature (150 °C), but the thermo-oxidative aging resistance of ZDMA deteriorates at high temperature (180 °C). The reason will be discussed in Section 3.6. For EPDM with the coined antioxidant /MC, the decrease in elongation at break is obviously less than that of
The hard wall hose suitable for industrial water or cooling water with temperature not higher than 120˚C (248˚F). Technical Description Tube: Black EPDM rubber, aging resistance, heat resistance, weather resistance, wear resistance Reinforcement: High tension textile fabric or cord, helix steel wire
6/8/2015· Effect of temperature on the aging rate of the maximum charge storage capacity. By investigating the maximum charge storage capacity (Q m) and the effects of temperature variation from 25 to 55 °C and cyclic aging on the degradation of Q m, valuable results may be generated to aid in the determination of appropriate usage conditions.Figure 5 shows that Q m gradually decreases with an
Aluminum hoses have the lowest rate of temperature resistance, being able to handle anything up to 400° F. Stainless steel hoses are a cut above almost every other high temp hose due to the levels of heat that they can withstand. A high temperature duct made …
8 Introduction. Polytetrafluoroethylene (PTFE) is an engineered fluoropolymer. Outstanding resistance to chemicals is one of its primary attributes. A broad temperature range of -54°C to 260°C makes this hose material suitable for the majority of fluids and aient temperature conditions found in most industries.
