For chemical transfers, special hoses are required that have appropriate resistance to extreme conditions. In selecting them, one must take into account compatibility with the transferred chemical, temperature, pressure, and other factors. In this article, we introduce the common types of hoses used in the chemical industry!
Chemical-Resistant Rubber Hoses
These hoses are made from synthetic rubber materials such as EPDM (ethylene-propylene-diene monomer), nitrile, or FKM (fluoroelastomer). They provide excellent chemical resistance and can handle a wide range of acids, bases, solvents, and other chemical substances.
PTFE (Polytetrafluoroethylene) Hoses
PTFE hoses are extremely resistant to chemical substances, and even withstand extreme temperatures well. They are most commonly used for aggressive chemicals, strong acids, and corrosive substances. PTFE hoses offer excellent chemical resistance and have a low coefficient of friction.
Stainless Steel Hoses
These hoses are extremely durable and offer excellent resistance to corrosion. They can handle various chemicals, including aggressive acids and solvents. Stainless steel hoses are generally used in chemical processes that require high durability and resistance to extreme conditions.
Thermoplastic Hoses
Hoses made from thermoplastics like PVC (polyvinyl chloride) or polyurethane are ideal for certain chemical transfer processes. They have good chemical resistance to various substances while maintaining their flexibility. Before use, however, it is important to ensure that the employed thermoplastic is compatible with the transferred chemical substance or not.
Quality Chemical Hoses from IZOFLEX
When selecting a hose for chemical transfer, one must consider factors such as the type of chemical, its concentration, temperature, pressure, as well as any special requirements or regulations. Consult with the IZOFLEX technical team to make sure that the hose meets the intended application and ensures safe chemical transfer.
