Assuring HRSG and Boiler Pressure Part Quality

June, 2017 - Managing Boiler & Steam Cycle Pressure Part Integrity

This training course is primarily intended for experienced O&M staff working in thermal power and process plants, but could also be of interest to corporate engineering and management staff. The objective is to give attendees a comprehensive view of the strategy, actions and considerations involved in effectively managing and thereby assuring the integrity of piping, tubing and vessels that form the pressure boundary to steam or water process fluid. A range of topics relating to the design, inspection and repair of relevant components are treated using a combination of theory and numerous practical examples. The examples are all based on actual project cases encountered by Tetra Engineering staff at plants around the world.

Covered Piping System Maintenance Programme

Since 2007 the ASME B31.1 Power Piping Code has included Chapter VII, establishing mandatory requirements for Operation and Maintenance. The key elements of this program are discussed here, and require that Operators outline a detailed maintenance plan for their Covered Piping Systems (CPSs).  The Code also requires that operators perform regular Condition Assessments of their CPS ensuring that relevant degradation mechanisms are being covered.

Tetra provides the following services to Owners and Operators of Combined Cycle and Thermal Power Plants to help meet the ASME requirements and thereby assure the long-term integrity of their piping systems:

  • Technical Support For Implementing a B31.1 Compliant CPS Maintenance Programme
  • Grade 91 and CSEF Integrity Assessment
  • Piping Degradation Risk Assessments
  • Piping Inspection and Condition Assessments

Tetra has developed PipeVue 2.0, a unique and powerful software tool to manage the data from design, inspections and repairs of piping in an integral manner, by linking all this information to a 3-D model of plant piping and making it accessible through a simple click of the mouse.

Tetra Engineering in the Guinness World Records!

Tetra Engineering's own Andreas Fabricius and cycling partner Axel Carion are currently past the half-way mark of their World Record attempt to cross the South American continent North to South by bicycle.  Scott Napier's current record stands at 58 days.  See this photo below of Andreas crossing the Argentinian border at 4400m elevation (14400ft) days ago.  You can follow their journey (here) and track their progress.  Their journey is raising money for Pompiers Sans Frontières (Firefighters Without Borders - see website), providing crucial resources to underfunded firefighters in South America.

Tetra Engineering is sponsoring their effort and wishes them good luck!

ASME B31.1 Covered Piping Systems' Mandatory Requirements

Since 2007, the ASME B31.1 Power Piping Code has included mandatory requirements on the Operation and Maintenance (O&M) of Covered Piping Systems (CPS), previously called High-Energy Piping. The main concern is that the safety of these systems is very dependent on good O&M, which justifies its inclusion in the Construction Code. There is room for flexibility depending on individual circumstances but the responsibility is squarely laid on the Operating Company.
