The stripping and non-stripping processes of hydraulic hose assemblies have their own characteristics: the stripping process significantly improves the pull-off strength (30-40%), pulse life (2-3 times) and sealing reliability by removing the outer rubber layer to expose the reinforcement layer, which is suitable for high pressure (above 3000 PSI), high-frequency pulsation and safety-critical parts; the non-stripping process retains the complete outer rubber layer, with the advantages of high installation efficiency (increased by 50%), low equipment cost and good environmental adaptability, suitable for low-pressure circuits, temporary repairs and other scenarios. When choosing, it is necessary to comprehensively consider the pressure level, dynamic characteristics, service life and cost factors. The stripping process is recommended for key parts, and the non-stripping solution can be evaluated for secondary circuits.

LT1402 High Temperature Resistant Furnace Door Cooling Hose - Professional Industrial Cooling Solutions-

LT1402 High Temperature Resistant Furnace Door Cooling Hose - Professional Industrial Cooling Solutions

2025-03-28

LT1402 high temperature resistant furnace door cooling hose is a professional cooling solution designed for high temperature industrial environments such as steel smelting, glass manufacturing and metal casting. The product adopts a three-layer composite structure: the EPDM inner rubber layer ensures heat resistance and chemical stability, the high tension fiber and spiral steel wire/PP core reinforcement layer provide excellent compressive resistance, and the NBR&PVC flame retardant outer rubber layer with stainless steel armor effectively resists 540℃ high temperature radiation and mechanical damage. With a medium tolerance temperature of -40℃ to +100℃ and an external radiation resistance temperature of 540℃, the large-caliber design ensures efficient cooling, and has flame retardant and explosion-proof characteristics, which significantly extends the service life and reduces maintenance costs. It is an ideal choice for high temperature industrial furnace door cooling systems.

As a key connecting element of the hydraulic system, the material selection of hydraulic joints directly affects the system performance and service life. The main materials include: carbon steel joints have the advantages of high strength (700bar+) and low cost, but require surface anti-rust treatment, and are suitable for high-pressure systems such as engineering machinery; stainless steel joints (especially type 316) have outstanding corrosion resistance and hygienic properties, suitable for special working conditions such as food, medicine, and marine environment, but the cost is relatively high; brass joints have good electrical and thermal conductivity and are easy to process, suitable for low-pressure systems below 300bar and fuel pipelines; aluminum alloy joints are light in weight (only 1/3 of steel) and are mostly used in weight-sensitive fields such as aerospace. When selecting, the working pressure, medium characteristics, environmental conditions and cost factors should be comprehensively considered. Carbon steel is preferred in high-pressure conventional environments, stainless steel is suitable for corrosive occasions, brass is suitable for low-pressure systems, and aluminum alloy is selected for lightweight requirements. With the development of technology, new composite materials and intelligent joints will provide more options.
