Specifications and Features of Wire Spiral Hose Assemblies

阅读更多

Spiral wrapping is used to protect bundled wires and hoses from abrasion. It’s easy to install and provides a good fit around hoses or wires, working well in a variety of environments.

Spiral hoses are able to handle higher pressures without the pressure drop that occurs with braided hoses. They can also withstand high pulses and operate in freezing temperatures, making them an excellent choice for snowplows and other winter equipment.

How to extend the service life of steel wire wound hose assembly

The type of hose and how it is used may affect the life of the assembly. Frequent oil changes and maintaining a clean environment are important steps to extend hose life. It is also important to make sure that all parts of the hose are compatible.

Metal hoses can be subject to several types of corrosion, depending on their type and the conditions they are exposed to. Chemical attack, oxidation, fatigue cracking and distortion can all lead to premature failure. These problems can be avoided by using the correct hose alloy for the application.

Spiral hydraulic hose is generally more rigid than braided hose and can handle higher pressures. This makes them a good choice for applications requiring high pulse or wear. They are also less susceptible to corrosion than other types of hose.

For example, SAE 100R12 four-wire spiral hydraulic hose has a maximum pressure of 6500 psi, making it ideal for heavy equipment and earthmoving machinery. The rubber sleeve is resistant to wear and chemical attack and is easy to clean. It resists freezing temperatures, making it ideal for snowplows and tractors. It has an internal configuration with a “backbone” of spiral wire to prevent kinking. This also supports full vacuum service.

Reasons for the inner layer of steel wire to break

Spiral hose is designed for high pressure applications such as petroleum and water based hydraulic systems. They can operate in temperatures from -40 to +302 degrees Fahrenheit and withstand pressures up to 6500psi. They have high wear resistance and excellent pulse life. This makes them ideal for use on heavy equipment and vehicles such as snowplows and tractors.

Metal hose assemblies can fail for a number of reasons. Improper application—use of hose for purposes other than those for which it was designed; overuse—exceeding design pressure limits; and environmental conditions—corrosive attack and temperature exposure. The hose alloy should also be matched to the chemical media to ensure compatibility.

Another common cause of failure is pressure cracking. This is usually caused by constant or pulsating stress that exceeds the fatigue limit of the alloy. The resulting stress cracks on the surface of the oxide film make it susceptible to corrosion. Another possible cause of corrosion is the turbulence of abrasive chemicals on the alloy surface. This type of corrosion is called erosive corrosion and can be reduced by reducing the fluid velocity or lining the hose assembly with a protective liner.

Primary raw materials used in manufacturing wire wound hose assemblies

Polytetrafluoroethylene (PTFE): An extruded polymer that is highly durable, flexible, and corrosion-resistant. It comes in a variety of thicknesses, diameters, and colors. It can also be used as a sealant. PTFE has high chemical and heat resistance and is resistant to oils, acids and alkalis. It is also very easy to work with and can be welded by fusion welding.

ECTFE (ethyl chloride-fluoroethylene): An extruded polymer similar to PTFE, but with higher thermal and electrical properties. It is extremely durable and used in applications involving corrosive chemicals. It comes in different diameters, thicknesses and colors.

Sleeve: A protective sleeve placed over a hose to protect it from harsh external environments such as high-temperature materials or traffic. Using anti-static products in hoses that will be exposed to static electricity is a good choice.
