How To Specify Hydraulic Hose Fittings

Hydraulic hose fittings connect hoses to pumps, valves, cylinders, and other components used in the entire hydraulic system. These safe connections help control and direct the flow of hydraulic fluid to where it is needed, while preventing leakage and maintaining pressure safely.

Experts say it is beneficial to distinguish hoses from complete hose assemblies. Although the choice of hose is obviously important, choosing a hose without considering accessories can be a costly mistake. Any hose assembly includes accessories for specific applications. Industrial hose assemblies must have hoses, fittings, and methods to connect the fittings to the hoses. For most hydraulic hoses, the fitting has a barbed end, which is inserted into the inner diameter of the hose, and a shell or clamp, which is connected to the cover or reinforcement.

Crimping is the most common method of assembling hoses and fittings. Once the crimp specifications of the specific hose and accessories are checked, the crimping machine is adjusted to the proper crimp diameter setting. The next step is to lubricate the tube, push it into the end of the hose, and then insert the tube into the crimping die. Start the crimping device, close the mold and permanently compress the fitting onto the hose.

Many companies offer no-skive options on their hoses. Peeling refers to a process in which part of the hose cap or even the inner tube is removed-the reinforcement layer is exposed-before the hose end is connected. No-skive hose does not require this step. Many users prefer the no-slip option because it makes hose assembly faster and reduces the risk of hose damage during crimping.

Therefore, in addition to hoses, users must also choose accessories based on chemical compatibility and connection safety. In addition, it is also necessary to consider the segmentation of the application, such as operating pressure, flow capacity, environmental and temperature extremes, and operating fluids.

When installing the hose assembly, pay attention when determining the thread of the connection. Usually, it is connected from one standard to another standard port, but there is not enough contact to ensure safety. In addition, most of the accessories are certain hoses of a specific brand, and may not cooperate with other brands. Although the size of the joint usually corresponds to the size of the wire, there may still be differences in the choice of joints for the same size hose.

For safe and durable hydraulic components, the "correct" components are couplings, hoses, crimping equipment and accessories, which are designed to work together. Tolerances vary from manufacturer to manufacturer and are not interchangeable. Different components from different manufacturers may adversely affect the coupling retention. Accidental mixing and matching may cause hose rupture, joint leakage and blow-out ends, injuring or even killing workers.

Introduction Of Abrasion-Resistant Steel Plate (AR plate)

What is AR plate?

Abrasion-resistant steel plate (AR plate) is a special plate product of high-carbon alloy steel plate, which is mainly used for work that will produce large-area wear. Wear-resistant steel plates are welded on the surface of low-carbon steel or low-alloy steel to form one or more layers of alloys with higher hardness, weather resistance and higher wear resistance, and have better plasticity and toughness. The thickness of this alloy wear-resistant layer is generally 1/3 ~ 1/2. It is adding carbon, manganese, nickel, chromium, boron and other alloys to the steel plate to relatively increase the hardness and toughness of the steel plate. Adding carbon can increase the hardness of the steel plate, but if we add too much carbon to the steel plate, it will become brittle and reduce the tensile strength.

Commonly used in:

Because the wear resistant plate mainly has high wear resistance and good impact performance, it is suitable for welding, cutting, bending, etc. From the point of view of its material, the cost performance is very high, so it has been welcomed by the public in recent years. It is widely used in industrial fields with more extreme environments, such as heavy industrial equipment, mining, electric power, agriculture, construction, and cement industries. This kind of wear-resistant steel plate is very convenient and time-saving in the repair process.

AR plate characteristics

The advantages of wear-resistant steel plates are as follows:

1) Good wear resistance

The wear-resistant steel plate has a layer of alloy wear-resistant layer on the outside, and the composition of this layer of alloy wear-resistant layer contains chemical elements such as carbon and chromium, making it twice the hardness and wear resistance of ordinary steel plates.

2) Strong impact resistance

According to what we mentioned above, there are mainly two layers of wear-resistant steel plates, the base material is low-carbon steel or low-alloy steel plate and a layer of alloy wear-resistant layer. The outer alloy wear-resistant layer can be used to resist the wear of the wear medium, and the inner base material can withstand the load of the medium, so as to achieve good impact resistance. At the same time, it can withstand the impact and abrasion of the high drop hopper in the material conveying system.

3) Good heat resistance

Adding vanadium, molybdenum and other alloys to the alloy wear-resistant layer can increase the heating degree of the steel plate. Approximately can withstand high temperature wear ≤800℃.

4) Superior corrosion resistance

Since the alloy layer of the wear-resistant composite steel plate contains a large amount of metallic chromium, it has good rust and corrosion resistance.

5) Convenient processing performance

The wear-resistant steel plate can be processed into various industrial parts through cutting, bending, welding, etc. according to the needs of the project.

Abrasion-resistant steel plates have higher hardness than ordinary steel plates, and have stronger wear resistance and corrosion resistance.
