Standard PTFE Convoluted Tubing

Catalog Number

ACMA00038510

Description

Convoluted PTFE tube is available in standard sizes, from 1.50mm to 37mm ID, with standard or light wall grades, and smooth bore or anti-static properties. Corrugated tubing can be supplied cut to specific lengths, together with either straightened, cuffed or flanged ends for easy connection.

Appearance

The standard colour of our convoluted PTFE tube is black - it is nonconductive, however 14 different colours (including natural) are available upon request.

Application

Electrical cables in the aerospace industry
Light duty chemical transfer hoses
Military vehicles
Food processing industry
Electronics industry

Case Study

Potential of Corrugated PTFE Tubing for Arterial Implantation

Tariq, Mohammed Gulfaraz, et al. Journal of Physics: Conference Series. 1529. 5. IOP Publishing, 2020.

This work systematically tested the mechanical properties of corrugated PTFE tubing, including volume expansion, stretching and elongation, rolling wear, and burst testing by applying realistic industrial pressures. Overall, corrugated PTFE shows potential as a suitable material for replacing damaged/disease arteries.
Mechanical Testing and Performance of Corrugated PTFE Tubing
· The volume expansion test results showed that the calculated volume expansion percentage of the coiled PTFE samples for 0.25-, 0.375-, and 0.75-inch diameter tubes was 3-5% higher than expected.
· The tensile test results showed that the corrugated PTFE tubing also showed consistent 120-150% elongation for different hose sizes.
· The burst test results showed that the burst pressure of the corrugated PTFE tube ranged from 18-34 bar, which was within the expected range.
· According to the rolling wear test results of the three pore sizes, the corrugated PTFE tube did not show any failures and exceeded the expected 1000,000 cycles.
