Emco,
1633types of stainless steel.why does this called stainless.what is passivation related to SS? What is sensitisation in stainless? Examples of diffrent type of steel e.g. austenatic,martensite,ferritic etc. 304,303,316. How to get rid of carbide formation in SS and stablization in SS.(347 etc.)Different type of heat treatments. Iron carbon diagram. Nelson chart with respect to corosion. Diffrent type of corosion and causes. Carbon equvalent number. Welding related questions.(requirement of post and pre heating in welding). welding of SS. If you have pre experience in maintenance then Material and welding related questions will be there. Then various types equipment in plant (a) static (b) rotatic in pumps and compressor,turbines funda of balance drum and balance disc, balancing line. Impulse wheel, wheel chamber pressure and its effect on turbone health if this increases. Thermal expansion of turbines and with respect to how foundation bolting are designed. Fixing of lower casing before dismantling. Most important shaft alignment and balancing of rotating equipment,classification of static and rotatic equpment used in process plants. Materials for diffrent services as refinery plants fertilizer plants, cement plants, sulphur plants, crude oil with higher sulphur services, then third important thing is codes, standards and recommended practices of diffrent organisation like ASTM,ASME,API,TEMA,BIS,IS,ISO,NPFA,OISD etc. diffrent type of work permit systems fire and safety point of view.
