Boiler Standards

603350-000020-000030 1 Scope This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric dry irons and steam irons , including those with a separate water reservoir or boiler having a capacity not exceeding 5 l, for household and similar...

1.1 This specification2 covers chromium-molybdenum alloy steel plates intended primarily for welded boilers and pressure vessels designed for elevated temperature service. 1.2 Plates are available under this specification in several grades having different alloy contents as follows: ?...

5.1 Control of silica in boiler feedwater and boiler water is necessary to minimize the formation of scale-forming silicates that decrease heat transfer in the boiler. Volatilization and carryover of silica with the steam may cause hard, glassy siliceous deposits to form on...

1.1 This specification2 covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc. These steels are listed in Tables 1 and 2. 1.2 Grades containing the letter, H, in their designation, have requirements different from those...

5.1 Excessive amounts of sodium can indicate the presence of materials that cause high wear of burner pumps and valves, and contribute to deposits of boiler heating surfaces.

4.1 Regulatory Requirements-The USA Code of Federal Regulations (10CFR Part 50, Appendix H) requires the implementation of a reactor vessel materials surveillance program for all operating LWRs. Other countries have similar regulations. The purpose of the program is to (1) monitor changes in the...

4.1 These test methods are applicable for such purposes as impurity detection and, in some cases, the quantitative measurement of ionic constituents dissolved in waters. These include dissolved electrolytes in natural and treated waters, such as boiler water, boiler feedwater, cooling...

4.1 Chloride ion is under regulation in waste water, and must, therefore, be measured accurately. It is highly detrimental to high-pressure boiler systems and to stainless steel, so monitoring is essential for prevention of damage. Chloride analysis is widely used as a tool for estimating...

1.1 This specification2 covers hot- and cold-finished bars of stainless steel, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction.2 Note 1: There are standards covering high nickel,...

1.1 This guide provides a framework to characterize coal combustion products (CCPs) situated in active or inactive storage units for potential harvesting and beneficial use and may be considered a companion standard to Guide E3183. 1.2 A framework is provided in this guide to address critical...

This guide specifies standard specification for nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels with various grades intended for such use as a boiler, superheater, heat exchanger, or condenser tubes. Heat and product analysis shall...

This specification covers thermal insulating bricks made from fire clay that are used as backup insulation for refractory furnace linings of boiler furnaces. The bricks shall be composed of heat-resistant materials that have been burned or fired to produce the desired density, strength, and...

1.1 This specification covers grades of pyrolysis liquid biofuel produced from biomass intended for use in various types of fuel-burning equipment under various climatic and operating conditions. These grades are described as follows: 1.1.1 Grade G is intended for use in industrial burners equipped...

5.1 Conductivity measurements are typically made on samples of moderate to high ionic strength where contamination of open samples in routine laboratory handling is negligible. Under those conditions, standard temperature compensation using coefficients of 1 to 3?% of reading per degree Celsius...

5.1 Accurate measurement of organic carbon in water at low and very low levels is of particular interest to the electronic, life sciences, and steam power generation industries. 5.2 Elevated levels of organics in raw water tend to degrade ion exchange resin capacity. Elevated levels of organics in...

5.1 Silicon (Si), a metalloid, is the second most abundant element in the earth's crust. Various forms of silica (silicon dioxide SiO2) are found in quartz, sand, and rocks. The degradation of these rocks results in silica found in natural waters. Silica in natural waters can be found as ionic...

This specification covers ferritic/austenitic (duplex) stainless steel forgings for boilers, pressure vessels, and associated equipment. The steels shall be manufactured using melting and forging processes. Forgings may be machined before solution annealing. The forgings shall undergo...

1.1 This specification2 covers hot- and cold-finished bars of stainless steel, including rounds, squares, and hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction.2 Note 1: There are standards covering high nickel,...

4.1 The weight per unit area measurement is an indication of the relative cleanliness or dirtiness of the boiler. It is used to determine the effectiveness of the boiler chemical treatment program and to determine the need for chemically cleaning the boiler systems. Allowing...

4.1 Master Matrix-This matrix document is written as a reference and guide to the use of existing standards and to help manage the development and application of new standards, as needed for LWR-PV surveillance programs. Paragraphs 4.2 - 4.5 are provided to assist the authors and users involved in...
