PTFE Pharmaline hoses are designed to replace conventional silicone rubber hoses in pharmaceutical, chemical and food process fluid transfer applications where the silicone rubber hose does not perform in accordance with the application requirements. This may be due to a requirement for improved autoclave life cycle performance, or improved chemical resistance, or improved internal cleanability. Whatever the conditions, Pharmaline hoses provide the solution.
Material:Smooth inside, corrugated outside PTFEReinforcement:From 1/2” AISI 316 steel wire helixExternal layer:Transparent siliconeWorking temp.:From -73°C up to +204°C (working pressure depends on temperature)
Characteristics:
PTFE Pharmaline hose is made of smooth inside and corrugated outside PTFE. The construction combines the properties of smooth hoses (ease of cleaning, uninterrupted flow) and high flexibility that is specific to corrugated hoses. It is a lighter version of PTFE Pharmaline hose designed for traditional fitting-hose connection. Hoses in all diameters are resistant to full vacuum up to +140°C. A standard PTFE Pharmaline hose, GP version has the internal layer made of PTFE according to the requirements of FDA 21 CFR 177.1550 standard. An antistatic version, marked AS, is also available, made in accordance with FDA 21 CFR 178.3297 standard. Both GP and GP AS hoses were tested and they both conform to the requirements of USP Class VI. The material of the external layer- platinum cured white silicone rubber is compliant with USP Class VI. PTFE Pharmaline hose can be optionally manufactured in accordance with ATEX directive and adequately labeled – Directive 94/9/EC.
For temperatures above +130°C reduce the maximum working pressure given in the tables by 1% for each 1°C of temperature rise above +130°C.Example: at +170°C temperature, maximum working pressure for AF-PHGP-X-10 is: 6 bar – (170°C – 130°C) x 1 = 6 bar – 40% = 3.6 barSafety factor (working pressure/ bursting pressure) is 1:4.
Applications:
PTFE Pharmaline hose is designed for transfer applications in high purity conditions both inside and outside the hose. It is widely used in pharmaceutical, biotech, chemical and food industry. As an alternative to silicone hoses it allows for visual control of a medium in the hose, but it is significantly more resistant to numerous chemicals and temperature. Unlike silicone hoses, PTFE Pharmaline hose can undergo countless steam sterilization without the risk of degradation of the hose and/or adverse changes in its material.
