一. The most important performance requirements for hoses
When picking a hose, it's vital to think about these main features:
The hose needs to be able to handle both high and low temperatures, depending on how it will be used. For instance, cleaning with hot water or steam at high temperatures is common in food processing, and hoses must be able to handle temperatures above 120 °C. The pharmaceutical sector might need to store things at low temperatures.
Performance under pressure: Choose the right level of pressure resistance based on the system's maximum working pressure. Different types of hoses, including braided reinforced or spiral steel wire, can handle different amounts of pressure. You need to adapt the hose to the conditions in which it will be used.
Corrosion resistance: The hose material must be very resistant to corrosion when it comes into contact with chemicals, oils, acids, bases, or pharmaceutical solvents. This is to prevent ageing or leakage.
Hygiene and safety: Hoses used in the food and medical industries must be non-toxic, odourless, easy to clean, and not let harmful substances move into the medium.
二. Important things to look for to see if the hose satisfies the standards
To find out if the hose satisfies the standards, you need look at the following things:
Material analysis: In the food sector, food-grade silicone or PVC pipes are used. In the pharmaceutical industry, polytetrafluoroethylene (PTFE) pharmaceutical hoses are preferred because they are very chemically inert and can withstand high temperatures. Medical hoses with smooth inner walls can help reduce turbulence and residue, which lowers the danger of contamination.
Standard certification: This is the most significant thing. Some common certificates are:
Food contact certification from the FDA (Food and Drug Administration); USP Class VI (United States Pharmacopoeia Biocompatibility Standard); ISO 9001 Quality Management System Certification; EU Food Contact Regulation (EC 1935/2004); and so on.
Flexible sanitary hoses should be non-toxic, resistant to corrosion, able to handle high temperatures, and easy to clean. They should also be able to transport food and work with CIP/SIP cleaning systems.
The FDA and USP Class VI must certify polytetrafluoroethylene pharmaceutical hose to make sure that no contaminants are emitted during the pharmaceutical process.
The inner wall of a pharmaceutical hose should be smooth and free of burrs so that bacteria can't stick to it and drugs can't get contaminated. This is because the pharmaceutical business has strict standards for purity.
三. How to tell if hoses are good quality
When buying something, you can use the following practical approaches to check:
Check the surface for cracks, bubbles, dirt, distortion, or uneven colour.
Test for flexibility: bend the hose by hand to see whether it is soft and won't break or change shape easily.
Use expert tools to test for cracking or leaking under simulated operating pressure in a pressure resistance test.
Chemical compatibility testing: Check the compatibility depending on the transport medium to make sure it won't corrode.
Hygiene compliance testing: Suppliers must send migration testing records to show that hoses don't leak toxic substances, notably in the food and drug industries.
四. Summary
When buying hoses, you need to think about a lot of different factors, such the material, certification, pressure resistance, temperature resistance, and hygiene, to make sure that the product fulfils industry standards and the unique needs of the job. Only hoses that meet safety and quality standards can assure the safety of production and the quality of the products.
What to Do: If you have any questions about buying hoses, you should talk to expert suppliers, ask for product certification records and testing data, and test samples in real-life situations. Pick flexible sanitary hoses or polytetrafluoroethylene pharmaceutical hoses that you can trust to protect your production system.
