High Pressure Hose
Like the name implies, the high pressure hose is aimed at heavy duty tasks that require a strong, durable and reliable hose – generally speaking, these products can resist a pressure of up to 40-50,000 PSI (over 3,200 bar), and their inner diameter vary between 1 and 2 inches. In addition to this, a high pressure hose is also considerably lighter than traditional rubber hoses, they have a lower volumetric expansion and their bend radius is smaller as well.
The materials used for manufacturing a high pressure hose vary based on the application of the hose, although resistant thermoplastic is the most commonly used material. The thermoplastic is then reinforced with steel wire in order to improve its lifespan and to make it even more durable. Neoprene or armorcoat are two of the most commonly used cover compounds for this type of hose.
After they are reinforced, these hoses are safe to use in the oil and gas industry, in the automotive industry as well as for high pressure hydraulics. They are considerably more reliable and stronger than traditional rubber hoses, which are prone to tearing throughout the years. The pressure hose is also designed to resist weather and ozone, as well as flames, oil and a variety of chemicals. The more advanced products are also designed to withstand UV-light.
The cover of the high pressure hose varies from one manufacturer to another, but usually it involves synthetic rubber that is resistant to oil and abrasion. The added layer of tensile steel wire has a series of benefits in addition to improving the life span of the hose: it adds extra strength and flexibility, and it makes the hose almost twice more resistant against cuts and abrasions. Despite the fact that it is seriously reinforced, the hose is still very lightweight, compact and easy to use and store.
Some of the most common areas of application for the high pressure hose include rescue tools (such as water blasting used in firefighting), bolt tensioning, high impulse applications, heavy oil lines and hot oil applications (usually up to 275 degrees Fahrenheit), the petroleum industry, mining, chemical production plants as well as a wealth of cleaning applications that require high pressure.
The amount of pressure the hose can withstand varies from one model to another, but high pressure hoses should resist anywhere between 15,000 and 40,000 PSI, depending on manufacturer. They are safe to use between temperatures of -40 degrees Fahrenheit and over 200 degrees Fahrenheit, they meet the flame resistance requirements that apply in the United States and the minimum bend radius is usually between 8-14 inches. The high pressure hose has a high impulse life, it delivers constant pressure and flexibility and there is a wealth of pressures, temperature ratings and sizes available on the market.
The inner tube of the hose can be made from nitrile, rubber or plastic and the reinforcement can contain either one or two braids of high-tensile steel wire – generally speaking, two braids are required in high pressure hydraulic applications that require maximum abrasion resistance.
