Professional Hydraulic Hose Fittings Manufacturer Since 2003.
The choice between rubber, thermoplastics, and plastic for hydraulic hose replacement comes down to three options. Each material offers its own set of performance characteristics. Rubber hoses typically last 5 to 10 years. Thermoplastic variants work for 3 to 7 years, while metal hoses push past the decade mark in service life.
The right core material is a vital component of system efficiency and safety. Rubber hoses can handle pressures up to 3,000 psi effectively. Thermoplastic options take it further with pressure tolerance up to 6,000 psi. Temperature tolerance varies substantially between materials. Silicone stands out with its ability to withstand temperatures above 300°F (150°C).
This article explores the essential factors in selecting core materials for hydraulic pipe replacement. The focus stays on pressure requirements, temperature ranges, chemical compatibility, and long-term performance factors that shape your decision.
The inner core is the main component of a hydraulic hose that contains and moves hydraulic fluid through the system. This vital inner layer directly touches the hydraulic fluid. Its construction and material choice significantly affect how well the system performs.
We made the core from synthetic rubber, thermoplastic, or PTFE (Teflon). The core material needs to have these properties:
● It must work well with hydraulic fluids
● It should be flexible for operations
● It has to resist different temperatures
The inner core works as one part of a three-layer system with reinforcement layers and protective covers. The innermost part acts like a blood vessel that creates a safe path for hydraulic fluid to flow through the machinery.
Today's hydraulic pipe cores feature advanced designs like the CORE (COaxial Rescue Equipment Technology) system. This system uses a high-pressure inner hose wrapped in a low-pressure outer hose. The coaxial design uses para-aramid fiber instead of steel wire and shows better resistance to kinks and pinholes.
The success of the core depends on its material and construction. Synthetic rubber cores are very flexible and resist chemical breakdown from hydraulic fluids. Thermoplastic cores handle high temperatures better and keep their shape under pressure.
Manufacturers create an extruded inner layer that keeps fluid flowing smoothly without contamination. The core must resist system pressures and not warp or break down, for it will impact for how long and with what efficiency a hydraulic system will function.
Choosing the proper industrial hose is important for efficiency, durability, and most importantly, for your safety. Replacing a hose? There are significant factors to remember when selecting a new one that will function effectively and serve your operation's requirements. There are three important factors to remember:
Temperature is a critical consideration when selecting an industrial hose. High temperatures can cause degradation of materials, premature wear and failure. Use a proper hose material for durability and performance in extreme temperatures.
● High-Temperature Resistance: Oil and gas and automotive and food processing sectors require hoses with high temperature resistance. Silicon and fluoropolymer work best for such an application, for such hoses will not become rigid and will not deform even at high temperatures.
● Low-Temperature Resistance: Hoses for cold temperature use must resist becoming stiff and cracking. Thermoplastic and rubber hoses function well in below-freezing temperatures, offering fluid conveyance with no loss in durability.
● Choose the Appropriate Material: In selecting a proper one, know its temperature range and the period of use it will encounter. Know the temperature range and duration of exposure to ensure the selected material can withstand those conditions and perform optimally.
Industrial hoses consistently carry corrosive, toxic, and reactive chemicals. To assure safe and long-lasting performance, a compatible hose material must then be chosen for such chemicals.
● Handling Corrosive Chemicals: Chemical processing, petrochemicals and drugs and oil & gas industries require acid, solvents and corrosive chemicals resistant hoses. Hoses with a fluoropolymer cover can work effectively in such a scenario, offering high durability and chemical resistance.
● Leaks and Failures: In the event a hose is not compatible with its transported fluids, it will break, degrade, or leak over a period of time. It will cause contamination, equipment failure and risk to safety.
● Choose the Right Material: First check what chemicals the hose will handle. Rubber and stainless steel are good for mild chemicals, fluoropolymer and silicone for strong or harsh chemicals. Choosing the right material will prevent damage and keep the hose safe and efficient.
Hose flexibility is critical for safe and effective function, most notably in environments in which hoses have to move, bend, and reposition regularly.
● Safety Benefits: Inflexible hoses will break and shatter and produce perilous situations. Elastic hoses move with ease, reducing the risk of breakage and catastrophic failure.
● Easy to Install and Use: Flexible hoses are easier to install in tight spaces and can move with the equipment, reducing stress on the hose and connected parts. Whether in a stationary or moving system, flexibility ensures smooth fluid transfer.
● Choose the Right Flexibility: The level of flexibility needed depends on the application. Convoluted hoses are good for tight spaces, smooth-bore hoses for better flow and easier to clean. Also, consider how temperature and pressure will affect flexibility as extreme conditions can affect how well a hose can bend without damage.
Selecting the proper hose material for use in an industrial environment is important. There are several materials with specific benefits; use according to your requirements.
Fluoropolymer hoses exhibit high chemical resistance and can effectively handle hostile and corrosive chemicals. They can resist extreme environments and work well in extreme environments. Since they can resist a range of chemicals, acids, and solvents, industries working with hostile chemicals prefer them.
● Chemical Processing: For transporting strong chemicals, acids, and solvents
● Pharmaceuticals: For safe delivery of sensitive and regulated drugs
● Food & Beverage: Meets food-grade materials' sanitary requirements
● Semiconductor Manufacturing: For high-purity use in contaminant and clean fluid transfer
These hoses are designed for industries that require them to have flexibility, durability and chemical resistance.
Silicone hoses can handle high temperatures without losing flexibility or breaking down. They can withstand heat over 300°F (150°C) and remain strong and flexible. Unlike other materials, silicone does not harden, crack or become brittle under heat stress, making it a reliable choice for demanding applications.
● Automotive: Engine coolers, turbochargers and intake systems
● Food & Beverage: For hot beverages including drinks, oils and steam.
● Pharmaceuticals: For application in high temperature resistant, sterilized environments
● HVAC: For high temperature air and gases in the ventilation
Silicone hoses stand at the head of industries with long-term, high temperature resistant hoses that serve over a period of time.
Rubber hoses can be designed with natural rubber or synthetic rubber, both with their respective strengths. Natural rubber is stretchy and flexible but not resistant to chemicals and high temperatures. Synthetic rubber, including nitrile or EPDM, is durable and resistant to oils, weather, and ozone and is best for extreme industrial environments.
● Pros: Rubber hoses are flexible, affordable and versatile. They resist wear and can handle good pressure levels, which is perfect for many industries.
● Cons: While durable, rubber hoses don’t perform well in extreme chemical conditions or very high temperatures. They may not last as long as specialized materials like silicone or fluoropolymer.
Stainless steel hoses are durable and long-lasting. They resist corrosion and rust, and therefore, make ideal high-pressure and extreme temperature use hoses. Stainless steel hoses can work under hot and cold temperatures and guard against wear, oils, chemicals, and gases. Because stainless steel doesn't react with most chemicals, it promotes safe fluid delivery free of any kind of contamination.
Stainless steel hoses are for:
● High Pressure Systems: For when hoses have to withstand high pressure.
● Chemical Handling: For secure carriage of corrosive and high-purity chemicals
● Automotive & Aero: For fuel hoses, hydraulic and turbocharger applications in which high strength and thermal resistance are desired.
Thermoplastic hoses are light, flexible and budget friendly, performance varies based on the composition. They can be reinforced for higher pressure resistance and provide excellent protection against abrasion. These hoses are for applications that require flexibility, easy handling and durability.
● Pros: Thermoplastic hoses have numerous uses and a low cost. They resist chemicals, can deform when impacted, and have a high level of impact absorption.
● Cons: While best for most applications, they won't function with high temperature and high pressure, and won't function with stainless steel and silicone hoses. They will wear out earlier in abusive chemical or physically abusive environments.
Selecting the proper hose is critical for efficiency and safety in working in extreme environments. Industry hoses must function in extreme temperatures, high-pressure, and with abrasive materials. Using a proper hose prevents damage, system failure, and downtime at a high expense.
Some industries, including automotive, food processing, and chemical manufacturing, require high temperature hoses and not a disintegration propensity. High temperature hoses have been designed to have both integrity and elasticity at such temperatures.
● Silicone Hoses: Can resist 500°F (260°C) temperatures and have durability and flexibility. Automotive, HVAC, and food processing industries utilize them best.
● Fluoropolymer (PTFE) Hoses: Chemically and temperature resistant, with a temperature range of -70°F to 450°F (-56°C to 232°C). Used in pharmaceutical and chemical industries.
● Stainless Steel Hoses: High temperature, capable of withstanding temperatures over 600°F (315°C). Common in oil, gas, and steam service.
Consider the temperature at its extreme, for how long it will have to endure heat, and whether temperatures will change. Make sure that the hose is durable and flexible under desired temperatures for dependable performance.
Just as hoses can become weakened through high temperatures, extreme cold can cause them to become brittle, crack, and become inflexible. Hoses designed for low temperatures, in contrast, are engineered to maintain full function and pliancy, even in frozen or below zero temperatures.
● Rubber Hoses: Nitrile Rubber and EPDM (Ethylene Propylene Diene Monomer) function best in cold temperatures. These compounds exhibit high flexibility in extreme cold and thus function best for use with fuel pumping, refrigerants, and low-temperature chemicals.
● Thermoplastic Hoses: Thermoplastic hoses represent a dependable alternative for cold temperatures. Thermoplastic hoses maintain flexibility at temperatures down to -40°F (-40°C). Thermoplastic hoses are most often utilized in hydraulic circuits, pneumatic tools, and in out-door and refrigerated use when durability in frozen temperatures is critical.
● Fluoropolymer Hoses: Fluoropolymer hoses resist high and low temperatures and, for that reason, can best serve in cryogen use and in aerospace industries, in which components must endure extreme temperature fluctuations.
For the best performance in cold temperatures, utilize a flexible hose at your system's minimum temperature rating. It will have to resist breakage, cracking, and stress-related failure under the minimum pressure and contact with fluids required.
Hoses that face rough surfaces, constant motion, and high use can become abraded and wear out prematurely through abrasion. Abrasion can make them leak, become compromised, and break down early. Abrasion-resistant hoses resist mechanical loads and friction, and therefore, extend durability.
● Stainless Steel Braided Hoses—A durable and robust hose is encased in a stainless steel braid, safeguarding it from any form of damage, and is thus ideal for rough industries including mining, oil and gas, and construction.
● Rubber Hoses—Reinforced rubber hoses with synthetic yarns and strong cords impart durability and wear and tear resistance. They are used in pneumatic and hydraulic circuits in instances of repetitive motion generating wear and tear.
● Thermoplastic Hoses – Thermoplastic hoses have strong constructions with nylon and polyurethane and are both durable and lightweight in nature. Thermoplastic hoses can effectively serve in agricultural, construction, and materials handling operations.
When selecting an abrasion-resistant hose, consideration must be taken for the type of wear it will face (scraping, dragging, etc.), working environment, and desired level of reinforcement. Solutions including cloth-reinforced covers and braided metal can protect against deterioration and maximize life in a hose.
