Using super wear-resistant UPE rubber hose correctly is essential for the safety of workers. It is important to understand the size specification, causes of super wear-resistant UPE rubber hose damage, and main raw materials used in super wear-resistant UPE rubber hose.
One of the biggest causes of hose failure is tube erosion from internal high-velocity fluids and fluid particles. Heat aging is another common cause. This happens when the elastomeric inner tubes lose flexibility and stiffen.
ultra wear-resistant UPE rubber hose size specification
The ultra wear-resistant UPE rubber hose size specification provides a standard range of hose sizes for most common applications. These hoses are designed to handle a wide variety of fluids and are ideal for many chemical transfer and suction discharge applications.
These hoses are made from a combination of materials to provide the best performance for these applications. These include polytetrafluorethylene (PTFE) lining and polyester fibres for high pressure resistance, abrasion resistance and chemical resistance.
This hose is also highly resistant to acid, alkalis and solvents. It is a high-performance product for use in a wide range of industrial environments, including food and beverage, dairy, meat and poultry processing plants.
Note that PTFE liners can be extremely flammable so this hose is not recommended for use in areas where it could be exposed to flames or explosions. This includes applications such as passing steam, water or other liquids into rubber moulding presses to heat the mould and rapidly cool it before reheating in the next cycle.
These types of applications may require you to'stiffen' the end fitting to prevent it kinking. You can either apply a rubber layer directly to the ferrule or use a 300mm (12-inch) rubber covered grade such as EPDM, Silicone Rubber.
causes of super wear-resistant UPE rubber hose damage
External damage to the fittings and hoses can lead to hydraulic hose failures. These include crushing, kinking, and abrasions due to rubbing against other fittings, equipment, or the surrounding environment.
These abrasions may occur from non-compatible fluids, harsh chemical exposure in the operating environment or continuous chaffing against other equipment components. The most common abrasion is the ripping or pulling of a hose, but other types of damage may also be present.
In some cases, abrasion may result from exceeding the minimum bend radius for the hose (measured from the inside edge of the hose). As shown in the image below, this can cause physical tears along the hose's outside.
Excessively dry air is another type of abrasion that could cause hose damage. This can cause the plasticizers in your elastomeric inner tube to begin to degrade and harden at high temperatures. This can lead to cracks inside the hose that eventually reach outside.
To avoid overheating, confirm hoses are rated for the temperatures required by your application and use heat guards to protect them from areas where they can become too hot. If this is not possible, reducing the ambient temperature can help prevent overheating, but be sure to verify that hoses are rated for the constant temperatures you will be using them at.
The main raw materials for super wear-resistant UPE rubberhose
There are many raw materials that can be used to make super wear-resistant UPE rubberhose. Each one has its own unique properties. These include abrasion resistance, flexibility, rebound, tear resistance, chemical properties, and temperature use ranges.
Natural rubber is made of latex and has extraordinary mechanical properties like tensile strength and tear resistance. Natural rubber is not as resistant to chemicals, fuels and oils as synthetic rubber.
Synthetic rubber is made of polymers like butadiene and styrene. These polymers are chemically resistant to most petroleum products and have excellent water resistance.
The durometer for neoprene/chloroprene synthetic rubber is 60. This is one of the oldest synthetic rubbers and is excellent for abrasion, tearing, flexibility, rebound, UV aging, ozone resistance, oil, gasoline, and temperature use ranges up to 225 degf.
Nitrile, a copolymer between acrylonitrile & butadiene, has exceptional mechanical properties. It is resistant to water, chemicals, fuels, and oils, which makes it an ideal material for automotive fuel hose.
Tubing is an integral component of many industries and can be used with a variety different rubbers depending on the purpose. It is used for circulating and transporting liquids and gases, as well as for electrical and signal transfer.
