Choosing the right hose for a job is vital for increasing uptime and safety. The wrong choice could lead to unneeded downtime, higher costs, and higher risks.
Maintenance technicians and plant managers must consider the material, construction type, end connectors, and application of hoses. They also need to monitor hose performance regularly to determine whether replacement is necessary.
Dimensions and specifications for large diameter petroleum hose
When sizing a pipe, it is important to consider the distance between the end points as well as the pressure loss that will occur when the hose is being used. This is due to friction between the fluid’s inner surface and the hose’s length.
The hose’s inner diameter (I.D. is the measurement of the straight distance between the two furthest points of the hose’s inner surface, and it is usually designated in inches or fractions of an inch. Metric sizing may be offered as well, but is not always necessary to meet exact specifications.
Jason has a large range of hoses in the petroleum and oilfield categories. These products are designed for a wide range of applications including suction and discharge of petroleum-based fuels, transfer of liquified natural gas, and the removal of vapors from gasoline.
This multi-ply, high-pressure rubber hose features an external clockwise PVC Helix for easy dragging. A safety ohm ground wire embedded in the hose walls prevents static electricity buildup. This hose is made to withstand the harshest industrial and agricultural hydraulic systems, while still delivering the highest flow rates and floatation.
causes of large diameter petroleum hose Breaking
The plasticizers in the rubber elastomer that provide flexibility to hoses, break down and harden when they are exposed to heat. Any combination of oxygen and high temperature can accelerate the hardening process.
Another effect is heat aging, caused by running hoses through high temperature areas and over long periods of time. This condition can cause a hose’s flexibility to lose and stiffen up, which can lead to a burst pipe or leak.
A hose that shows signs of heat aging, stiffening at room temperatures, or other signs of heat stiffening may need to be replaced. You can also replace the hose with one that has a lower continuous operating temperature such as a flexible tube made of metal.
After being removed from an application, a hose may show signs of hardening or cracking. This is an indication that the hose has been exposed to aerated oil that has caused oxidation of the inner tube.
Pinholes and weeping on the hose cover are common causes of hose failures. Also, fluids leaking from the cover (such as oil or kerosene or fuel gas) can cause corroded wires around the fitting. This damage can be caused by improper assembly techniques or a lack of proper lubrication, possibly from rubbing against foreign objects–other hoses, the wrong size clamp, sharp corners or brackets.
The main raw materials for large diameter petroleum hoses are
Fluorocarbon, nitrile rubber and fluoropolymer are the main raw materials for large-diameter petroleum hose. The nitrile rubber, Buna-N, is the most common type of hose for phosphate ester base hydraulic fluid (Skydrol(tm)).
Neoprene is also a synthetic rubber compound that is similar to Buna-N and has good resistance to petroleum products. This is the best material for use with phosphate ester base hydraulic fluid (Skydrol(tm)).
Polytetrafluoroethylene, or PTFE, is another commonly used fluoroplastic chemical, which has carbon atoms shielded by fluorine atoms. This gives PTFE strong inter-atomic bonds, which give it chemical inertness.
Various other materials are also used to make large diameter petroleum hose. The hose reel must be made of corrosion-resistant, durable and temperature-resistant materials for use in toxic environments.
The customer can specify a variety of specifications. Some of these include the size, ends and intended application.
Pressure: The hose must be able to withstand any pressure it is intended to. This is especially important when the application requires pressure changes or surge pressures.
Delivery: The hose should be delivered to the customer at the specified date. This ensures that the hose is in good condition and does not need to be repaired before it can be used.
