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 of large diameter petroleum hose
When sizing a hose, you must take into account the distance between the two end points and also consider the pressure loss that will occur as the hose is used. This is due to friction between the fluid's inner surface and the hose's length.
The hose's internal diameter (I.D.) The hose's internal diameter (I.D.) is the distance between the two furthest points on its inner surface. It is usually measured in inches or fractions thereof. 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 can be used for a variety of purposes, including suction and discharge from petroleum-based fuels, transfer liquified gas, and removal of gasoline vapors.
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 causes a hose to lose its flexibility and stiffen up, which may cause the hose to burst 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. The hose can also be replaced with one that is rated for a lower continuous operating temperature, such as a flexible metal tube.
A hose can also show signs of hardening and cracking after it is removed from an application and left to cool. This is a sign that the hose was exposed to aerated oils that caused oxidation in the hose's inner tube.
Other common hose failures include pinholes or weepages on the hose cover, leaking fluids (such as oil, kerosene, fuel gas or water) inside the cover and corroded wires near the fitting. This damage can be caused either by poor assembly techniques or a lack proper lubrication.
the main raw materials used in large diameter petroleum hose
The main raw materials used in the manufacture of large diameter petroleum hose are nitrile rubber, fluorocarbon and fluoropolymer. The nitrile rubber, Buna-N, is the most common type of hose for phosphate ester base hydraulic fluid (Skydrol(tm)).
Neoprene, a synthetic rubber compound, is similar to BunaN and has excellent resistance to petroleum products. This material is ideal 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.
There are a number of specifications that can be determined by the customer. Some of these include the size, ends and intended application.
Pressure: The hose should be able to withstand the maximum pressure that it is designed to. This is especially important if the application demands change in pressure or surge pressures.
Delivery: The hose should be delivered to the customer at the specified date. This ensures that it is still in excellent condition and will not need to be repaired before use.
