What is the inner wall structure of Grease Hose 35Mpa?

Hey there! As a supplier of Grease Hose 35Mpa, I often get asked about the inner wall structure of these hoses. So, I thought I'd write this blog to share some insights.

First off, let's talk about why the inner wall structure of a Grease Hose 35Mpa is so important. These hoses are designed to handle high - pressure grease, around 35Mpa to be exact. That's a ton of pressure, and the inner wall has to be up to the task. It needs to be tough enough to withstand the force of the grease flowing through it without bursting or leaking.

The inner wall of a Grease Hose 35Mpa is typically made of a special type of rubber or thermoplastic material. These materials are chosen for their excellent chemical resistance and durability. Grease can be pretty harsh on materials, so the inner wall has to be able to resist corrosion and degradation.

Rubber Inner Wall

Rubber is a popular choice for the inner wall of high - pressure grease hoses. Natural rubber has good elasticity and flexibility, which allows the hose to bend and flex without cracking. But for high - pressure applications like our 35Mpa grease hoses, synthetic rubbers are more commonly used.

One of the most common synthetic rubbers used is nitrile rubber (NBR). NBR has excellent resistance to oil and grease, which is crucial since the hose will be constantly in contact with these substances. It can also handle a wide range of temperatures, from relatively cold to moderately hot environments. This makes it suitable for various industrial applications.

Another type of rubber that might be used is ethylene propylene diene monomer (EPDM). EPDM has great weather resistance and can withstand exposure to ozone and UV rays. It's also resistant to many chemicals, making it a good choice for the inner wall of grease hoses, especially if they'll be used outdoors or in environments with a lot of chemical exposure.

Thermoplastic Inner Wall

Thermoplastics are also an option for the inner wall of Grease Hose 35Mpa. Thermoplastics have some advantages over rubber. They are often lighter in weight, which can make the hose easier to handle and install. They also tend to have better abrasion resistance, which is important if the hose is going to be dragged or rubbed against other surfaces.

Polyurethane (PU) is a common thermoplastic used in high - pressure hoses. It has excellent mechanical properties, including high tensile strength and tear resistance. This means it can handle the high pressures of the grease flowing through the hose without breaking down. PU also has good resistance to oils and greases, similar to NBR rubber.

Reinforcement Layers

The inner wall alone isn't enough to handle the 35Mpa pressure. That's where the reinforcement layers come in. These layers are usually made of high - strength materials like steel wire or synthetic fibers.

Steel wire reinforcement is very common in high - pressure grease hoses. It provides excellent strength and can withstand a large amount of pressure. The steel wires are usually braided or spiraled around the inner wall of the hose. Braided steel wire reinforcement gives the hose good flexibility, allowing it to bend easily. Spiraled steel wire reinforcement, on the other hand, provides more strength in the axial direction, which is important for withstanding the high - pressure flow of grease.

Synthetic fibers like aramid or polyester can also be used for reinforcement. Aramid fibers, such as Kevlar, are extremely strong and lightweight. They can provide high - strength reinforcement without adding too much weight to the hose. Polyester fibers are also a good option, as they have good resistance to stretching and can handle high - pressure applications.

Outer Cover

The outer cover of the Grease Hose 35Mpa is also an important part of its structure. It protects the inner layers from damage, such as abrasion, cuts, and environmental factors. The outer cover is usually made of a rubber or thermoplastic material similar to the inner wall, but it may have different properties.

For example, the outer cover may be designed to be more resistant to abrasion if the hose is going to be used in a rough environment. It may also have better weather resistance if the hose will be exposed to the elements. Some outer covers are even designed to be flame - retardant, which is important in industrial settings where there may be a risk of fire.
