Inspection and Testing GPP offers Alleima HP160 specialty tubing in a variety of sizes available in various random lengths. Our tubing is designed to provide superior performance in this extreme service. GPP’s tubing is manufactured for applications requiring both strength and corrosion resistance.

Special Process: Extended Pressure-cycle service life of tubing can be significantly extended by a one-time factory process known as “autofrettage,” which involves a single over-pressurization to introduce favorable residual stresses into the tubing wall. Autofrettage is generally required to achieve adequate pressure-cycle service life for most 100,000psi tubing applications and is available at GPP as a factory option.
