Parker's Autoclave Engineer’s Medium Pressure Tubing for Hydrogen

Parker Autoclave Engineers offers a complete selection of austenetic, cold drawn stainless steel tubing designed to match the performance standards of Parker Autoclave valves and fittings.

Parker Autoclave Engineers medium pressure tubing is manufactured specifically for high pressure applications requiring both strength and corrosion resistance.

The tubing is furnished in random lengths between 20 feet (6 meters) and 26.5 feet (8.0 meters). The average is 24 feet (7.3 meters).

Medium Pressure Tubing is available in six sizes and a variety of materials.

All Parker Autoclave Engineers manufactured tubing is line marked repeatedly along the full length with our name, country of origin, Heat number, PO number, tube dimensions (Nominal OD and ID), PAE Part Number, Manufacturing Specification, and Pressure Rating (MAWP ++ Room Temp)

See our pressure tubing guide with all variants

The Parker's medium pressure tubing are available in different sizes. For details see our Medium Pressure Tubing guide - click here

Introduction: Parker Autoclave Engineers offers a complete selection of austenetic, cold drawn stainless steel tubing designed to match the performance standards of Parker Autoclave valves and fittings. Parker Autoclave Engineers medium pressure tubing is manufactured specifically for high pressure applications requiring both strength and corrosion resistance.

Features: Standard Tubing is manufactured in accordance with ASME B31.3 Chapter IX standards using UNS S31600/S31603, 316/316L Stainless Steel material, cold worked to Parker Autoclave proprietary standards

Materials: Parker Medium Pressure Tubing are available with most commonly requested tubing materials CW 316 SS, 2507 Super Duplex*, and Inconel 625* (specifications on next page), we have other options outlined in our Technical brochure. These include NACE/ ISO 15156 capable materials for a variety of corrosive applications

Size: Parker's Medium Pressure tubing is furnished in random lengths between 20 feet (6 meters) and 26.5 feet (8.0 meters). The average is 24 feet (7.3 meters). Medium Pressure Tubing is available in six sizes and a variety of materials.

Testing: Sample pieces of tube for each lot are tested to con- firm mechanical properties. Hydrostatic testing is also performed on a statistical basis and is conducted at the working pressure of the tube. Parker Autoclave will perform 100% hydrostatic testing at additional cost if desired.

Tolerance: The outside and inside diameters of the tubing are subject to special inspection and are controlled within close tolerances to assure proper fit. The outside dimension of this tubing is intentionally “undersized” to match the requirements of the threading die used to put the connection thread on the tubing. See the technical data sheet for more details
