MATERIALS OF CONSTRUCTION FOR PROCESS EQUIPMENTS

OVERVIEW

Description

In any process plant like refinery, petrochemical plant or power plant, the process equipments form the vital part of the installation. The success or failure of any of such process plants depends on whether the correct materials were used for manufacturing the process equipments. The materials must be suitable for the required process, the corrosive conditions, temperature considerations etc, and should last the expected design life. This should be achieved at the optimum cost keeping in view safety and reliability considerations and meeting the codes and standards for the materials.

This course explains the methodology and techniques to select the most appropriate construction material for various process equipments like pressure vessels, heat exchangers, process columns, piping etc. The course also covers practical guidelines in specifying the correct ASTM material specifications and selection of their correct equivalents in BS, JIS, DIN standards wherever material substitution is required

Objective

On completion of this course the trainee/s will be competent in:

  • Main factors in deciding the suitable material for a given service
  • Understanding of basic metallurgy and Material suitability for various process applications
  • Various metals, alloys their applications and limitations
  • Factors governing material choice :Corrosion, Temperature, and other factors
  • Weldability and fabrication considerations
  • Materials for pressure vessels and heat exchangers
  • Piping materials
  • Materials for critical applications-sour, caustic, hydrogen service etc.
  • Codes and standards in material selections
  • Typical ASTM specifications and grades
  • Selection of alternative materials
  • Do’s and Don’ts in selecting material substitutes

Who should Attend

This course is ideally suited for process engineers, designers, technical managers, quality control persons, corrosion engineers and all those involved in materials selection and evaluation of materials for petroleum, petrochemical, power, and other process industries. The plant engineers, inspection and maintenance personnel related to pipelines, tanks, pressure vessels etc. will find this course quite valuable.
