Under-deposit Corrosion Presentation at ASME POWER 2014

Under-deposit Corrosion Presentation at ASME POWER 2014

At the 2014 ASME Power Conference in Baltimore, David Moelling of Tetra Engineering presented the recent research paper titled: Role of Boiling Mode and Rate in Formation of Waterside Deposits in Heat Recovery Steam Generator Evaporator Tubes, written by David Moelling and James Malloy. The paper discusses results from research in the theory of boiling mode and deposit formation, employing advanced thermal simulation of evaporation in real boiler models, and compares results with actual experiences in recent years.

Covered Piping System Maintenance Programme

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.

ASME B31.1 Covered Piping Systems' Mandatory Requirements

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.
