The key properties of industrial rubber hoses temperature resistance, aromatic resistance, oil/fluid resistance, fatigue resistance, and ozone resistance. It is used to transfer water and steam hoses, air, oil and petroleum, and other chemicals. These hoses have high resistance to solvents and different chemicals.

Fuel Hose

Fuel hoses also referred to as fuel lines, are used in the fuel system to deliver fuel from the gas tank to the engine. Fuel hoses are reinforced by several layers so that the pipe can hold the pressure which generates in the vehicle’s fuel system. It has extremely low permeability to lower hydrocarbon emissions. Some fuel like ethanol and methanol needs hoses that have a high resistance to polar solvents. Rubber hoses with carbon can reduce the permeability of gasoline.

Automotive Hoses

Automotive hoses are also known as engine hoses, vehicle hoses, auto hoses, and car hoses. It is used in automobiles to transfer fluids to use in lubrication or cooling and hydraulics. Automotive hoses can carry fluids to engines, radiators, and other vehicle components. It allows fueling, lubricate, and cool these components to keep them from malfunctioning.

Radiator Hose

A radiator hose is used to remove excess heat from the coolant before it seeps into the engine. It helps to manage the flow of coolant from the water pump to the heater at an optimal temperature. The upper hose is connected to the top of the engine, and the lower hose is connected to the bottom of the radiator and the engine pump. It is resistant to coolant at elevated temperatures.

Barrier Fuel Line Hose

It is used in low-pressure fuel lines on blowers, grinders, mowers, off-road engines, pressure washers, and saws.

Pneumatic/hydraulic Hose

It is used to transfer pneumatic, petroleum base hydraulic fluid, lubricating oils, and antifreeze solutions. It can transfer diesel fuel only when the hose is when coupled with HY Series fittings.

Food and Beverage

Rubber hoses are used in food and beverage industries for transfer of liquids, gases, and air. They are made from FDA approved materials to ensure safety and hygiene.

Components of Rubber Hose

The Tube

The tube is the inner part of the composite hose and the line that comes into contact with any medium that is moved. Due to this contact, the material used to build the tube is essential. When the substrate’s chemical properties are not consistent with the chemical composition of the container, the structural stability of the whole container is affected.

The Reinforcement

The middle layer of the shaft is the reinforcement layer; based on the implementation of the shaft; it varies in structure and design. The primary goal of this sheet is to improve or enhance the tube sheet. In most cases, the tube cannot withstand the fluid pressure as it passes. This centre layer gives the strength to support the tube together.

Helical Reinforcement

The helical reinforcement method is used in suction applications. The architecture of the helix stops the tube from breaking apart and blocking out any flow.

Spiral

The spiral strengthening is perfect for high-pressure applications. The alternating layers, typically of steel wire, build a solid barrier that can survive more violent forms.

Braid

A braided reinforcing coating is mainly used for small to relatively high pressures. It can be built in single or multiple layers, so it’s an adaptable layer design.

The Cover

The cover is the last sheet of a hydraulic pipeline. The purpose of this layer is to protect the rest of the tube against external forces, the environment and to add extra safety levels. The cover layer is also built to withstand any condition in which the shaft works.

Process of Rubber Hose

Rebar Hydraulic Forming And Joining Equipment

Material Preparation

The first step in manufacturing a rubber hose is to prepare the rubber material. This involves mixing various chemicals and additives with natural or synthetic rubber to achieve the desired properties such as flexibility, strength, and resistance to heat, chemicals, and abrasion.

Extrusion

The rubber material is then fed into an extruder machine, which uses a rotating screw to push the material through a die to create a continuous tube or profile of the desired shape and size.

Vulcanization

The extruded rubber hose is then vulcanized or cured, which involves heating the rubber material to a specific temperature and pressure for a certain amount of time to cross-link the rubber molecules and give the material its desired physical properties. The vulcanization process can be done using steam, hot air, or other methods.

Reinforcement

To reinforce the rubber hose and improve its strength and durability, a layer of fabric or wire mesh is usually added to the extruded rubber tube during the manufacturing process. This layer is usually wrapped around the tube or embedded within the rubber material. manufacturing process. This layer is usually wrapped around.

Finishing

The final step in manufacturing a rubber hose involves cutting the tube to the desired length, attaching end fittings or connectors, and performing any final testing or quality control checks to ensure the hose meets the required specifications. manufacturing a rubber hose involves cutting the tube to the desired length, attaching end fittings.

How to Maintain Rubber Hose

Storage
It is fundamental to stock the hose properly before use. For this purpose, it is important to store the hoses:
At temperatures not exceeding 35 °C and not below 0 °C.
Far from heat sources.
Far from wet areas.
In dark environment in order to avoid premature aging.
Far from chemicals.

Proper Use Of Rubber Hoses
By using the hose, after having checked the technical data sheet, it is important to make sure that the hose:
Does not exceed the working pressure indicated.
Does not exceed the working temperature indicated.
Only conveys fluids compatible with the materials with which the hose is made.
Respect the manufacturer’s instructions on cleaning and sterilization.
Does not exceed the bending radius stated in the technical data sheet.
Avoids twisting.
Does not vibrate excessively.
Hoses installed between two fixed points must be supported by adequate fixing devices that do not hinder the normal movements of the hoses under pressure.

Maintenance
It is necessary to plan periodic maintenance of the hoses, paying attention to:
Potential damages on the cover: cuts, abrasions, visible reinforcement textile plies.
Hardened and rigid hose: the hose has aged due to temperature or chemical agents.
Warning: if the hose is bent, it might crack.
Changes in colour: they might indicate chemical attacks or ozone deterioration.
Bubbles on the cover: they might indicate permeation of fluids.
Leakages: they might indicate fitting problems or stagnation of materials.

Frequently Asked Questions Rubber Hose

Q: How Rubber Hoses are Made?

A: Rubber hoses are made of three main components: the tube, the reinforcement, and the cover. The tube is the innermost component and it is typically made of synthetic rubber or thermoplastic rubber. The reinforcement is the middle layer and it is typically made of one or more layers of textile cord or steel wire. The cover is the outermost layer and it is typically made of synthetic rubber, thermoplastic rubber, or polyurethane.

The three components are then joined together using a process called vulcanization. Vulcanization is a process where the rubber is exposed to heat and chemicals in order to improve its strength and durability. After vulcanization, the rubber hose is then ready to be used.

Q: How to store your hose properly？

A: Rubber hoses should be stored in a cool, dry place out of direct sunlight. Rubber hoses can be damaged by heat, cold, and UV rays, so it is important to store them properly. Rubber hoses should also be stored away from sharp objects that could puncture or cut them.

When not in use, rubber hoses should be stored in a hose reel or similar storage device. This will help to keep them organized and protected from damage.

Q: How long do rubber hoses last?

A: Rubber hoses have a limited lifespan and will eventually need to be replaced. rubber hoses are susceptible to a number of common defects, which can make them more difficult to repair. In most cases, it is best to replace a rubber hose that is damaged.

The lifespan of a rubber hose depends on a number of factors, including:

The type of rubber hose.

The environment in which the rubber hose is used.

The amount of use the rubber hose receives.

In general, rubber hoses should be replaced every three to five years. However, this can vary depending on the factors listed above. It is important to inspect rubber hoses regularly for signs of wear and tear. Hoses that are damaged or showing signs of wear and tear should be replaced as soon as possible.

Q: Can rubber hoses be recycled?

A:No. You should never put your old hoses into your recycling bin. They are one of the worst items for people at the recycling plant to deal with as they get tangled with other recyclables and can be a nightmare to extract and remove, as well as having the potential to cause machine breakdowns and become a safety issue for workers.

To dispose of your old rubber hose, you should put it into your general waste bin – for the same reason as listed above, it is a good idea to first cut the hose into smaller segments to prevent it from getting tangled during transport to landfill.

Important note: If your hose has been used to carry toxic or corrosive materials you should take extra care when handling and disposing of the hose as it may pose a health risk to you and others. When in doubt follow the manufacturer’s instructions.

Q: How do you keep rubber hoses from cracking?

A: Spray Protectant

Using an engine protectant every few months will keep your hoses looking clean, your rubber moist and flexible (drying out causes cracking), and extend the amount of time between repairs.

Q: What safety precaution is taken for using rubber hose pipes?

A: Cautions for using rubber hose pipe:

●Use the rubber hose pipe in the recommended range of temperature and pressure .

●When the rubber hose pipe is expanding and contracting with its internal pressure, please cut it into a slightly longer length than you need.

Q: What three things do you inspect on hoses?

A: Inspect for cracks, nicks, bulges (usually while hot); or a collapsed section in the hose and oil contamination; or fraying near the connection points. Look for parallel cracks around bends (caused by ozone), a hardened glassy surface (heat damage), or abrasive damage (hose is rubbing).

Q: Can you leave a rubber hose out in the winter?

A: If you leave a garden hose outside for winter, it will be damaged in the spring. The extreme cold causes the internal lining to break. With a drained hose in your hand, carefully coil it into a three-foot diameter. Don't coil it into a tighter configuration, however.

Q: Do rubber hoses deteriorate?

A: Rubber hoses and industrial hoses need proper care and maintenance in order to last a long time. While any hose will deteriorate over time, there are certain environmental factors that can contribute to this deterioration.

Q: How often should rubber hoses be inspected?

A: Hoses always should be inspected when the coolant is changed (recommended every five years or 150,000 miles, whichever comes first), or when other repairs are made to the cooling system, such as replacing a water pump, thermostat, radiator or heater core.

Q: How do you store rubber hoses?

A: Choose a designated spot for the hose, where you can place it and all its accessories. For the best results, store the hose on a reel that you can mount on the wall to keep it out of the way. If you don't have room for a reel, coil the hose neatly on the ground instead.

Q: Can you drink water from a rubber hose?

A:New study rates best and worst garden hoses: lead, phthalates ...

Don't drink water from a hose: Unless you know for sure that your hose is phthalate-free and drinking water safe, don't drink from it. Even low levels of lead may cause health problems. Some PVC hoses labeled drinking water safe contain phthalates.

Q: Can you run hot water through a rubber hose?

A: Hot Water Rubber hoses are premium quality hoses made with synthetic rubber. The hose can withstand up to 165°F and it's capable of handling landscaping and janitorial application. The heavy-duty crush proof coupling and rubber washer will ensure a water leak proof connection.

Q: Can rubber withstand 200 degrees?

A: Specialist grades of elastomer, such as fluorinated polymers (FKM), can resist temperatures over 200°C. Fully fluorinated elastomers, known as perfluoroelastomers (FFKM), when compounded and cured correctly, can withstand temperatures up to 316°C.

Q: What can I use to seal a rubber hose?

A: To mend a small hole or leak in your hose, try using electrical tape, duct tape or specially designed hose repair tape. Clean and dry the hose section before applying. Overlap the tape as you wrap it around the hose. Take care to not wrap too tight as the hose may wrinkle and the tape won't seal.

Q: How flammable is rubber?

A: As a material, rubber doesn't readily ignite, but when it is alight, the spread of fire and smoke can be rapid, with the material burning at extremely high temperatures. At 200°C, rubber begins to flow as a hot mass. At 230°C, it emits flammable vapours that can become trapped in the molten rubber.

Q: At what temperature does rubber become brittle?

A: Well-vulcanized rubber does not crystallize, but loses its ability to retract when stretched. Crude or elastic rubber, however, loses elasticity completely if cooled to 70-80° F. below zero. If bent suddenly at right angles a glass-like breakage occurs.

Q: Can you leave a rubber hose out in the winter?

Q: What will make rubber expand?

A: Reagents which cause rubber to swell but which do not attack or react with rubber include various hydrocarbons, ketones and lactones. Specifically useful are benzene, cyclohexanone, cyclohexane, toluene, xylene, hexane, heptane, acetone, gasoline, paramethadione, ethyl acetate, methyl ethyl ketone and amyl acetate.

Q: Natural Rubber vs Synthetic Rubber: What’s the Difference?

A: Natural rubber comes from Hevea brasiliensis (or the Pará rubber tree) which is a species of plant native to Brazil. Natural rubber is an extremely popular elastomer material, used in a wide variety of applications and industries.

Synthetic rubber is produced artificially and is created from a variety of polymers. Due to its artificiality, it can be manipulated and have a number of different properties added to it.

Generally, natural rubber is considered stronger and more flexible, but synthetic rubber has the advantage of being chemical and temperature resistant. Synthetic rubber also has the benefit of being more cost-effective.
