To ensure that the hoses function correctly, you must prioritise their cleaning in periodic intervals. When you tend to do that, you will experience better functional outcomes from the hoses, as the chances of them malfunctioning will be reduced. Chemical hoses, in particular, need timely cleaning with proper solutions because some of those substances might possibly damage the hose tubes from within. Periodic cleaning can increase the life of your chemical hoses!
If you are new to industrial practices and are looking for a stainless steel flexible hose manufacturer, you ought to be aware of the right technique to clean them. And, this article will help you explore the right steps to master the process. Read along till the end!
Ensure your chemical hoses are kept clean and sanitised.
A chemical hose is a specialised type of hose that&#;s designed for the efficient and safe transfer of fluids or chemicals within the industrial setting. All of these hoses are quite essential for industries that deal with abrasive, hazardous, and corrosive materials, ensuring the protection of equipment, personnel, and the environment. Some of the different types of chemical hoses used in the industrial setup are:
Type 1 is used for conveying diluted chemicals.
Type 2 is used for conveying the concentrated chemicals.
In terms of materials, you can opt for thermoplastic, EPDM rubber, polyurethane, polyvinylidene fluoride, polyvinyl chloride, and stainless steel hose assemblies. Following that, some of the chemicals that move through these hoses include acids & bases, paints, solvents, and salt solutions.
Industries such as pharmaceutical, chemical, food, and others actively make use of chemical hoses in their facilities.
Chemical hydraulic hose maintenance is of utmost priority because it prevents operational failures, which could result in expensive downtime for the business. And, if the hoses aren&#;t cleaned periodically, the chemicals that move through them will leave their residual effects, which will further lead to loss of product quality, profitability, and productivity.
Contamination or cross-contamination might be an issue within industrial practices when the chemical hoses are used without proper cleaning or maintenance over time. Keeping the chemical hoses maintained is not just the demand of the production department but is also a compliance regulation with respect to safety and the environment.
Chemical hoses can be cleaned both by hand or by machines. When cleaning by hand, the professionals are asked to use all safety precautions and use a bucket full of cleaning solution mixture. On the other hand, when machines are used in the process, there are three common types of cleaning procedures for hoses that you can prefer:
The projectile cleaners are meant to use water or pneumatic pressure to launch the cleaning projectile through a tube.

This is the machine that directs the throw of water at an immensely high pressure through the hose to remove dust, mud, mould, mildew, and grime.
Here, a drill, motorised fan or air motor is used for turning the cleaning head and shaft. The rotary cleaning head is mounted on the flexible or rigid shaft. It can utilise cutting blades, buffing tools, nylon brushes, and other attachments for better
hose cleaning.
Ensure your chemical hoses are kept clean and sanitised.
Before you turn up to your hose assemblies manufacturer to get your setup of chemical hoses for industrial applications, you must learn about the right approach to maintaining them. So, here are the steps for you to clean convoluted hoses easily:
A primary inspection will be executed to check any potential damage within the hose. Cleaning a chemical hose will demand you to know what type of residue you can expect within.
Remove all the attachments to the chemical hose from the source and destination hubs to ensure you can properly clean the industrial equipment and its individual components.
The first round of cleaning will be approached with just solvent and water. This is to eradicate any loose residue.
The next step is to pick the right cleaning agent! There are many products available in the market claiming to be the best hose cleaner. But, you must take note of your hose material and the type of chemical residue within, for choosing the ideal cleaning agent that won&#;t damage the product.
Apply the cleaning solution to the hose, inside & out! The cleaning agent will do its work by loosening all the toughened chemical residues within the hoses. You just have to let the cleaning agent settle over the hose for a sufficient amount of time.
You can use brushing or piggling methods for implementing mechanical cleaning practices. The chosen cleaning method should not be abrasive to the hose material. Take optimal care while executing the mechanical cleaning process to avoid any form of damage.
You can consider rinsing the chemical hose with plain water to clean out all the broken-down contaminants. Repeat the rinsing process to ensure that no residual cleaning solution is left behind within the hose. Drain the water from the hose properly and ensure complete drainage to prevent accumulation of solvent or water.
Check the cleaned chemical hose for any sign of damage, wear & tear, or left-out contaminants. If you find any contaminants luring within, rinse it out with water, and repeat Step 7 properly. Verify that all the components of the chemical hose are clean and in the best of their condition. Run some quality checks to ensure that the chemical hose meets all the regulatory or safety standards.
Refer to the manufacturer&#;s guidelines yet again, and this time, assemble all your chemical hose components. Reconnect all the fittings and couplings with proper tightness and alignment. Finally, lubricate all the components before you can put the chemical hose into action.
Beyond following the ideal steps for chemical hose cleaning, there is a specific mechanism that improves the efficiency of the overall cleaning process:
When you intend to clean the hose, you must first attach a cleaning tank to the setup to remove the NVR (Non-Volatile Residue) deposits from the hose surface.
If the NVR levels do not go down after the standard clean-up, some modifications should be made to the system. In the process, the cleaning water within the additional tank must be changed frequently.
A scoop will be introduced to generate a form of reaction force over the hose surface, which will then flush out the contaminants. The design will further reduce the NVR levels, but the results might not still be satisfactory.
Scoops can be substituted with that of toothbrushes as well. But, if the brush bristles start to wear out, they might further increase the NVR level. Therefore, an industrial-type brush is developed for cleaning the chemical hose.
The industrial brushes will then be modified to be in the spiral form to be able to rotate in either direction.
Hose cleaning efforts will then be made at a temperature of 60 degrees celsius for burning the pump.
After this cleaning effort is implemented, you might still find some water stains within the hose, which might also be some contaminants. Therefore, an air jet mechanism will be implemented at the exit of your final cleaning tank.
Ensure your chemical hoses are kept clean and sanitised.
A systematic and thorough cleaning process is important for ensuring that your chemical hoses last for a long time and continue to transport chemicals or associated substances without any contamination issues. Without timely or proper cleaning efforts, you might experience immense productivity loss in your industrial operations.
Be assured of implementing continuous adaptation or improvement of the overall cleaning process based on the best practices and advancements being specified by the industry.
One more thing: whether you opt for flexible metal hose, composite hose, or PTFE hose for your chemical transportation requirements, the cleaning requirements will be different for all. So, it is better to connect with your chemical hose manufacturer and discuss with them the detailed cleaning process with compatible solutions to ensure hose integrity for the long term.
