IBR and ASME Boiler Codes

i think differance is not much big. we can consider the bigger one. but for boiler we can not just consider so its better to clear the doubt. let me also know.

If you work in an ASME code shop that is certified to build boilers. Ask your National Board inspector what he requires. As he does the certification its best to ask. Joint efficiency if Xray and heat treatment is performed can be 1. Material specifications and openings also have to meet code.

Unless your shop is certified and drawings are approved your shop isn't allowed to build a boiler.

ya i understood this.but im in dilemma why this variation.can you please clearly explain.by considering E=1 about 10-15mm thickness is reduced.this may reduce the cost of production to large event.how could i finalize this design.

can anybody conclude this discussion.

I'm retired but section 1 of the ASME code explains joint efficiency. Most shops use submerged arc grind off excessive weld and radio graph the weld. If xrays pass the drum is stress relieved in a furnace. Some code is primary and has jurisdiction but most places accept accept Asme section 1 or 4 if a heating boiler. As codes change frequently I can't give you a final answer. I would ask your code inspector.

Joint are calculated by welding methods and non destructive examination performed.

Section 8 is for air tanks is this the code your using.

i have fire tube boiler. one week before its started leaking where the water enters in shell. how to weld it please guide me.

You need to hire a repair shop with an R stamp. According to state code in any state which has adopted the National Board code they are the only people who are licensed to work on power boilers. This is for any welding on the boiler. If a threaded nipple is leaking buy a new extra heavy schedule 80 black iron pipe nipple. This you are allowed to do yourself.

design is for utility boiler
