What MGT Inc. Training Courses Cover

MGT Inc. no longer offers public and in-plant Training Courses. We provide all courses on CDs that contain the full text of the course notes in PDF format, suitable for printing and a Power Point slide presentation suitable for viewing by all persons interested in the subject.

Tubular Exchanger Inspection Maintenance and Repair provides information on inspecting, maintaining and repairing; and extending the life of tubular heat exchangers in the process and power generating industries.

The course refers to the ASME Boiler and Pressure Vessel Code; and make available for examination recent editions of the TEMA Standards, Heat Exchange Institute (HEI) Standards for Power Plant Heat Exchangers, and HEI Closed Feedwater Heater Standards, the National Board Inspection Code (NBIC) and API 510, the American Petroleum Institute Pressure Vessel Inspection Code and Recommended Practice API 572, Inspection of Pressure Vessels.

In our CD presentation we discuss Purchaser's, User's and Maintainer's Inspection (but not the inspection performed for ASME Code compliance). We summarize Inspectors Qualifications, teach how to write Inspection Briefs, and discuss pre-inspection conferences between responsible engineers and inspectors. We survey Inspection-During-Construction. We describe how the NBIC and API 510 apply the ASME Code's rules.

We cover Inspecting Shop and Field Repairs and Alterations, and Inspecting During Outages and Shut-downs. We begin with Record Keeping and Documentation, and go on to Determining the Character and Causes of Failures.

We discuss On and Off-Line Exchanger Cleaning, Non-Destructive Examining, Repair and Maintenance Procedures and Practices.

We discuss Scheduling, Cleaning and Safety Precautions. We examine How to Extend Usability of existing units beyond their design lifetimes and Using Exchangers for Services for which they were Not Designed. We suggest how to Mothball Surplus Units and Rehabilitate ones that have been out of service.

We include videos of Tube Hydroxpanding, Bolt Torquing and Borescoping Feedwater Heaters.
 

Closed Feedwater Heaters - Mechanical Aspects

Authors - Carl F. Andreone, P.E., Fellow of the ASME and Stanley Yokell, P.E., Fellow of the ASME

 
Closed Feedwater Heaters-Mechanical Aspects covers specifications; construction; inspection, maintenance and repairs; applicable codes and standards; effects of operating practices and modes. It does not cover thermal and mechanical design or Balance of Plant.

In our CD presentation we refer to the ASME Boiler and Pressure Vessel Code; the National Board Inspection Code (NBIC); the Heat Exchange Institute Closed Feedwater Heater Standards (HEICFHS); the TEMA Standards; the HEI Standard for Power Plant Heat Exchangers (HEIPPHS); and the Performance Test Code, PTC 12.1-2000, Closed Feedwater Heaters.

We review the applicability of various types of Feedwater Heaters and discuss Single-zone and Multiple-zone Feedwater-heater designs as well as horizontal installations, including heaters installed in the condenser neck, and vertical channel head-up and channel head-down installations. We cover Feedwater-heater Draining and Feedwater-heater Venting, Desuperheater, Condenser and Subcooler sections. Coverage includes Vent Collection System Construction; Feedwater-heater Vent Placement, Feedwater-heater Drain Placement, Cascading Drains; and Drain Level-control requirements. We review Feedwater-heater Nomenclature and Feedwater-heater Size Numbering.

We present a brief overview of the effects of feedwater heaters on the Steam Cycle Heat Rate.

We discuss requirements to be included in Feedwater-heater Purchase Specifications for new construction and replacements, including Channel Heads and Channel-access Designs as they relate to initial cost and long-term maintenance costs, and Replacement-bundle Purchase Specifications. We cover requirements for Tubesheets, Tubing Manufacture and Tube-to-tubesheet Joining.

We define the Basic Design Point, and discuss Alternative Modes of Operation, Deviations from Design Point, Transients and Upsets.

We examine Zone Arrangements and fabrication details and address requirements for Shrouds, Subcooling-zone Enclosures and Endplates, Baffle Systems in Desuperheating Zones and Subcooling Zones and Tube Supports in Condensing Zones.

Our brief Tube Vibration Overview includes illustrations of tube-vibration-caused damage, explanation of mechanisms that force tubes to vibrate and the information required for vibration analysis.

In our coverage of Feedwater-heater Inspection, Maintenance and Repair, we discuss Record Keeping, Inspection During Fabrication, routine On-Site Inspection, Inspections During Planned and Unplanned Outages, and Prior to and After Major Repairs.

We discuss Preventative Maintenance; Changing Out Bundles; Tube and Tube-Stub Pulling, including extracting specimens for failure analysis, Tube-end Problems, Tube Plugging and Sleeving. There is brief coverage of Alterations and Repairs.
 

Shell-and-Tube Heat Exchangers - Mechanical Aspects

Author - Stanley Yokell, P.E., Fellow of the ASME

Shell-and-Tube Heat Exchangers-Mechanical Aspects concentrates on heat exchanger hardware, performance requirements, inspection, maintenance and repair, life extension and troubleshooting of tubular exchangers used in chemical and petrochemical plants, oil refineries, power stations and industrial facilities. We do not discuss thermal design except where it affects the structure.

We refer to the ASME Boiler and Pressure Vessel Code the National Board Inspection Code (NBIC); the Heat Exchange Institute Closed Feedwater Heater Standards (HEICFHS); the TEMA Standards; and the HEI Standard for Power Plant Heat Exchangers (HEIPPHS);

We provide Guidelines to Mechanical Design Methods but not specific procedures. We explain the TEMA System for describing size and type and illustrate TEMA terminology and nomenclature. We examine Design Point Setting and effects on the structure of deviations, transients and upsets.

In Tubeside Coverage, we discuss Flange Bolting and show a video of torque-tension measuring to illustrate the importance of lubrication in bolting up.

In Shellside Coverage we discuss Construction, Expansion Joints and Vapor Belts and Baffle Systems and picture of a non-plate baffle/tube-support. We discuss Differential Pressure Design, connections of tubesheets to shells and channels.

The Tube Vibration Overview includes descriptions and illustrations of tube vibration damage, vibration forcing mechanisms and information required for vibration analysis.

We review various Codes and Standards that apply to heat exchanger manufacture, factory and post-installation inspection, alterations and repairs. The discussion of Shop Inspection, covers inspectors' qualifications, pre-inspection conferences, inspection tools and equipment; and the inspection brief.

We address Inspection for Maintenance and examining out-of service units.

We discuss techniques and provide guidelines for writing and reviewing heat-exchanger specifications.
