ASME B31.1, and you can find the table 136.4 for the correct NDE based pressure, temperatures and thickness.

That section also includes the post weld heat treatment.

Steam piping above 15psi

High temp water 16psi and/or 250degF

Is the rules for construction of power boilers.

Sec 1 is only for new boilers. 

State of MASS adopted sec 1.

Welded repair requires R-1 form and alterations require R-2 form.

The chief in charge has the responsibility to assure that those forms are handed to the correct authorities, but it is the responsibility of the organization performing the repair to distribute those forms.

9 parts:

PG - general requirement for construction

PW - Boiler fabrication by welding

PR - Boiler fabrication by riveting

PWT - Water tube boiler

PFT - firetube boilers

PFH - optional requirements for feedwater heaters

PMB - Miniature boilers

PEB - electric boiler

PVG - organic fluid vaporizers

Applies to boiler proper and the boiler external pipping. Superheaters, economizer and other pressure parts of the boiler connected to the boiler without valves, shall be considered parts of the boiler proper.

External pipping is any pipping from the boiler proper up to and including the valve or valves included on sec 1.

Conduction

Convection

Radiation

Conduction - molecules come in direct contact - metal stick in a fire

Convection - transferred by currents in a fluid / air - hot air rising above a fire

Radiation - transferred without a material carrier - heat or light from the sun

Parts of a boiler with water (wet steam) on one side and the products of combustion on the other side.

measured on the hot gas side and always expressed as square feet.

over 125 psi to be constructed of extra heavy material

min 1" max 2.5" seamless extra heavy

over 100psi two valves

pipe protected from heat according to code

volume is equal too twice the water removed from boiler when reduced to 4" below NOWL

must have means of cooling and venting

NDE non destructive exxamination

Genguard - phosphate and a polymer acts as a detergent to clean the water through the blowdown

Azol - corrosion inhibiter for the cooper in the chiller (the condenser uses titanium, no need to treat the water for it)

Bleach and ENX1000 - biocide

Losses are evaporation, drift and blowdown
