What is a chemical hose?
A chemical hose is a specially designed hose that is capable of transporting both, organic and inorganic solutions. This includes strong acids and bases along with other corrosive solvents. A chemical hose has special coatings to prevent it from being corroded by the liquid. It has a wide range of applications, ranging from industries and factories to scientific laboratories. The hose is usually used to transport a corrosive liquid or for loading or unloading a liquid from a container. There are further specifications in this type of hose. These specifications include the restrictive capability, the diameter of hose, its normal operating pressure and such. These specifications are thoroughly studied and evaluated before a hose is selected for an application. Sometimes acidic gases are also transported using hoses so the hose needs to be well suited for the high pressure along with the desired rate to chemical resistivity.
Factors to consider when getting a hose
As mentioned before, choosing the application of the hose is not the ultimate decision a company or a supervisor has to make. There are tons of specifications involved which require careful examination of the application to get the most suited hose. Following is a step by step guide to choosing the right hose for your application.
- Study the function of the hose. This means whether the hose will be used to suck, spray, transport or hold a liquid.
- Next, understand the degree of chemical inertness hose requires based on the liquid or the gas that is going to be used in the hose. You need to be absolutely clear what fluid the hose will be used for.
- Following in line comes the gauge pressure. A hose for transporting gas needs to withstand 100 times more pressure than a hose that needs to carry simple liquid. Due to this difference, you need to be clear about the pressure requirements of the hose.
- Then comes the decision of size of the hose. This should be fairly easy and obvious.
- At this point, you need to decide whether you need a bendable hose or a straight one. This depends on the surface area of the place where you intend to install the hose.
- Finally, make a list of accessories that you need to apply to the hose. This can be a clamp or a 3-way exit, anything. You need to be mindful about these accessories before getting the hose.
Safety tips for conducting pressure tests on hose
Chemical hose in factories and require regular pressure checks. This process often results in disasters due to negligence. Safety tips and techniques are not properly followed resulting in mishap. Following are some of the tips for a safe pressure testing in factories. These are some of the most crucial safety measures.
- A harmless gas needs to be used for testing. Usage of reactive gas can pose great threat in case there is a leakage and failure occurs.
- As the air contains good amount of oxygen which can supplement in burning process, it is necessary that the hose is free from any air before the test gas is supplied to the hose.
- No person should stand directly in front or at the back of the hose.
- When an inflammable gas or liquid is used, fire precautions must be taken by keeping a fire extinguisher and any other kit ready in case of an explosion.
- Medical assistance should be at quick disposal during the entire process
Maintenance tips for a longer life
In factories and even in laboratories, replacing the entire network of hose can be really costly and this is what usually happens when maintenance plan is not properly followed. Plascorp Chemical Hose Australia, especially, need regular maintenance for a longer life due to the reactive and corroding nature of fluid being used in them. Following are some of the maintenance tips that should be followed in every workplace containing hose.
- Never leave the fluid in the hose after working. Always bleed off the excess fluid from the hose before switching off the system.
- Avoid bending of the hose more than the stated angle. This can damage the inner surface of the hose, reducing the overall life-span.
- When storing the hose for a long time, take care of the temperature and humidity level of the storage compartment. Also, keep it away from direct sunlight.
- Perform routinely inspections for any crack or damage.
