PVHO-2 Maintenance


PVHO-2-2019 is a standard that provides technical requirements and guidelines for the operation and maintenance of Pressure Vessels for Human Occupancy (PVHO) systems that were designed, constructed, tested, and certified in accordance with ASME PVHO-1-2019, Safety Standard for Pressure Vessels for Human Occupancy (PVHO).

This standard also provides technical criteria for the user to establish the serviceability of a PVHO acrylic widow under its specific environmental requirements.

PVHO-2-2019 also provides information regarding the Design Life and Service Life of your acrylic cylinder and guidelines on inspections that can be done to extend the Service Life.

The service Life of the acrylic cylinder may be extended beyond the design life (10 years, 10,000 cycles or 40,000 hours) up to an additional 10 years or 10,000 cycles as long as 10 Year Life Extension Viewport Inspection is completed on or before the end of the design life (10 years or 10,000 cycles) and cylinder MVIs are completed at regularly suggested intervals (every 18-24 months)

The standard lists two levels of inspections; Operational Viewport Inspection (OVI) and Maintenance Viewport Inspection (MVI).


OVI requires viewports to be visually inspected prior to the first pressurization if pressurized more than once per day.

MVI shall be performed at every 24 to 36 months for windows less than design life and 18 to 24 months for windows greater than design life. (The design life of cylindrical windows pressurized internally is 10 years and MVI is required to extend service life for an additional 10 years.)

Sechrist now offers PVHO-2 Ten (10) Year Life Extension Viewport Inspection and Maintenance Viewport Inspection (MVI)


Ten (10) Year Life Extension Viewport Inspection – includes complete mapping and documentation of cylinder as well as inspection of seat and seal; includes repair and refinishing of scratches.
