Pre-Made Assemblies

Penflex builds a number of common assemblies to stock that are ready to load and ship at a moment’s notice from our Houston, TX location. Industry leading welds are performed by ASME Section IX certified welders and each assembly is leak tested, hydrotested, tagged, and stored in boxes or on easy-to-roll racks. All flanged assemblies are made with Type A pressure-tight stub ends.

Key Benefits of Penflex Pre-Made Assemblies

To ensure a longer life in service, Penflex pre-made assemblies incorporate these characteristics.

Heavy wall. Our line of heavy wall hoses offers greater corrosion resistance than do standard duty metal hoses, especially in areas where aggressive chemicals are being used.
Double braid. In addition to increasing the working pressure of a hose, the second braid layer protects the first. It’s a proactive approach given how hoses are handled during turnarounds.
Purged welds. Argon purging of welds ensures clean, contamination-free welds. With numerous chemicals involved in turnaround operations, this approach delays corrosion.

Other key characteristics include:

Lightweight. Our hoses are easy to move throughout turnaround operations and workers are less likely to hurt their backs in the process.
Pressure rated Type A stub ends. While many of our competitors use non-pressure rated Type C stub ends, we use pressure rated Type A stub ends.
Tested to 1.5x working pressure. Penflex uses conservative working and burst pressures for our metal hoses.
