It is important to understand how to test ultra-high pressure resinhoses and verify their integrity before you purchase them. There are steps you can take in order to ensure you're purchasing a high-quality product.
the reason for the rupture of the steel wire layer of the ultra-high pressure resin hose
The ultra-high pressure resin hose meets safety standards. It can be bent at low temperatures without affecting its serviceability. It is also rated at MAWP (maximum allowable working pressure).
The steel wire layer of the ultra-high-pressure resin hose meets the standard when the hose is in use. The hose's steel wire layer is subject to extreme pressure. This is why it is often used in oil field development or mine hydraulic support. Moreover, it can be used in various industrial departments, such as injection machines and different lathes. This hose can withstand pressure from various fluids, such as oil, water, and emulsions.
In addition to the steel wire layer, there are other elements that are vital to the integrity of the ultra-high pressure resin hose. These include the crimping of the hose and its corresponding fitting. These components are secured using crimping dies, which are mounted radially. The crimping tools are placed perpendicularly to the hose and the fitting's center, compressing the ferrule or sleeves of the hose. This feature eliminates static electricity from the hose.
This feature, while it may seem surprising, is a standard feature in ultra-high-pressure resin pipes. It prevents the steel wire layer from bursting, which is crucial for the safety of an oil field. It also aids in cooling equipment such as flash lamps or lasers. However, small cracks can make the cable less durable and allow aggressive fluids to reach metal wires. This can cause short circuits and eventual failure.
the connection and sealing method of the ultra-high pressure resin hose
An ultra-high pressure resin hose is constructed with an inner liner that is greater than 50 mm in diameter and a coupling that is attached to the inner liner by means of couplings. The metal-rubber chemical bonds hold the coupling in place. The inner liner is partially covered by a rubber compound containing up to 80 parts per weight of resorcine derivative. The rubber compound is chemically bonded to the thermoplastic inner liner. It is also chemically bonded to the coupling, and cannot be broken by non-destructive methods.
Ultra-high pressure resinhoses must meet the standards for connecting to high-pressure equipment or gas lines. The resin used to create these hoses is oil-resistant and contains an additive that enhances the adherence of the bonding material to other materials.
Perfluoroelastomer is a material made up of chains of monomers that join to form a polymer. It has good chemical resistance, high thermal stabilities, and low outgassing. This material also has excellent mechanical strength and is suited for both static and dynamic sealing applications.
Ultra-high pressure resin can be made from a variety of chemical compounds depending on the application. Each one has its own benefits.
The precautions for ultra-high pressure resinhose
You should not handle ultra-high pressure resinhoses incorrectly. Those who violate safety precautions could cause injury to themselves or others. Incorrect handling can lead to the hose falling apart and separating from the fittings. It also reduces its lifespan.
Precautions for using this hose include avoiding cuts and bubbles on its surface. In addition, the hose must be properly grounded after installation. It should not be connected with ordinary hoses as static electricity can accumulate and discharge. The hose should also be kept away from excessive heat and sulphide water.
Turn off the power supply to install the hose. Make sure there is no current flow. The hose should not be twisted or pulled because this will cause it to loosen and rupture. The nipple of the fitting should be installed on the hose in a perpendicular direction. The nipple should not be inserted in the hose if it is heated.
Misapplication is the most common reason for failure. Pin holes and blowouts can be caused by incorrectly installed clamps. The cover may also be damaged, or the hose may seperate.
