High Pressure Seamless
Rigid Tubing

Elite-HPT high pressure tubing are seamless and cold-drawn with high yield and tensile strength up to 88.000 psi (6.070 bar) from 1⁄4” up to 1” O.D.

Tubing is used in a various range of applications, not only for high pressure but also for aggressive (corrosive) medium.
Main applications are waterjet cutting, production lines, hydraulic and pneumatic testing. Tubing is suitable for liquids and gases.

Tubing can also be custom branded.

316L are the standard materials. Typical special materials (Hastelloy, Inconel, Duplex, Superduplex, Monel and others) are available upon request.

5-7m

Tubing is provided in random lengths of 5-7 metres (16,4-23 ft), it can be supplied to customer length as required and it can also be coiled (only 1⁄4”).

Safety notes

All high pressure fluids are potentially dangerous, never vent fluids without control and never lose connection components when the circuit is pressurized.Always choose the correct tubing and connection components for your application, considering all the application parameters. Tubing and nipples are static components in a system designed and they convey fluids without leakage. With fluctuated pressures make sure that the tubing rating is higher than eventual pressure peak of the circuit. Also consider that over long term the pressure fluctuation will wear the tube, therefore nominal maximum pressure should be much higher than the actual working pressure. Attention should be also given to fluid purity and it should not contain any debris which is abrasive.
