These codes and standards dictate minimum requirements for design, materials, fabrication, examination, testing, inspection, and certification of major components. The European and other boiler codes include ‘design by analysis’ (DBA) methods in determining minimum wall thicknesses and other design parameters. In the US, ASME Boiler & Pressure Vessel Section I for Power Boilers is written as ‘design by rule’ (DBR), which usually results in heavier wall thicknesses for pressure parts

A licensed inspector should be consulted with specific information to make this determination. Boilers and pressure vessels at 680 IAC 2-1-5 are exempt from the requirements for inspection and certification; however they are not exempt from the requirement for ASME standard construction.
The ASME Boiler and Pressure Vessel Code require at least one visual level gauge for every fired steam drum. The visual level gauge is the only product considered to give “Direct” indication of steam drum water level. However, the boiler code allows for “Indirect” indication to supplement and replace some of the “Direct” visual gauges.
The ASME - American Society of Mechanical Engineers - International Boiler and Pressure Vessel Code (BPVC) is made of 11 sections and contains over 15 divisions and subsections. Code Sections. I. Power Boilers. II. Materials. III. Rules for Construction of Nuclear Facility Components. IV. Heating Boilers. V. Nondestructive Examination. VI.

Code editions are effective on—and may be used on or after—the date of publication printed on the title page. Code addenda are effective on—and may be used on or after—the date of issue. Revisions become mandatory as minimum requirements six months after such date of issuance, except for boilers (or pressure vessels) contracted for before the end of the six-month period.
Since 1914, the American Society of Mechanical Engineers’ (ASME’s) Boiler and Pressure Vessel Code (BPVC) has served as a worldwide model for assuring the safety, reliability, and operational efficiency of boilers. In July, ASME will release the 2019 version of its BPVC code, updating each of the “living document’s” 12 sections.
I'm also in NJ, no it is not code nor required to use cross tees on residential steam boilers for control piping. However, it is certainly a nice touch and pretty much guarantees the standard 1/4 inch pigtail will not get clogged. Dave goes above and beyond most of his competition.
A 9-chromium-1 molybdenum alloy, T9 offers very good corrosion resistance with good high-temperature strength. It also has good oxidation resistance and can be used to 1200F maximum. Some times T9 is an adequate substitute for the more expensive stainless grades. The Boiler Code limits T9 to 1200F.
indicator. A Magnetic Level Gage can not replace the Code required direct reading gage glass. When the over 400 PSI Code option arrangement is used (two independent indicators for one of the gage glasses), the two indirect indicators must be continuously visible in the operators control area and the gage valves may be isolated.
In addition, commentary is provided on Section XI  of the Code, as the rules apply to CSS repair, replacement, examination, and inspection requirements.

Steam boiler has a important function to produce steam with the best quality and efficient. Combustion process give heat transfer to water inside water wall tubes then water will be evaporated continuously to generate steam. In the process of steam release, steam boiler needs a certain amount of water surface area.
Section I of the ASME Code contains rules for Power Boilers which, for the case of steam boilers, are boilers designed for a maximum allowable operating pressure (MAWP) greater than 15 psig. Section IV of the ASME Code would provide rules for steam boilers with a MAWP of 15 psig or lower. B31.1 Power Piping Code provides
As long as these temperature and pressure limits are met, copper tube and fittings can be used in both high- and low-pressure steam systems. The system must still be designed and installed to meet the requirements of all applicable local, state and federal construction and safety codes for steam applications.
