Base Metals (QB-402)

ASME Rated: Select this box if the material has been rated by the ASME.

Base Metal: Enter the base material used in the test. This is the metal or alloy that is welded, brazed, or cut. Most related fields will be automatically completed if the material is selected from the Material Browser. Selecting a material as the "Base Metal 1" will select that material for "Base Metal 2" as well. However, another material may then be selected or entered independently for either field. The material with the lowest P- or S-Number should be entered first, as should an unrated metal.

P- or S- Number: Enter the appropriate designation for the base material. This field will be automatically completed if the material is selected from the Material Browser. S-Number does not exist in the Code after 2008, so if 2009 or later is selected as the "Code year," this field will only allow P-Number.

Tensile Strength: Enter the tensile strength of the base metal. This field will be automatically completed if the material is selected from the Material Browser.

Thickness: Enter the coupon thickness used in the test. If a pipe is selected from the Pipe/Tube Browser, the nominal thickness of the pipe will be automatically inserted into the base material thickness field.

Diameter: If Pipe was selected as the "Product Form," enter the diameter of the pipe in this field. If a pipe is selected from the Pipe/Tube Browser, the diameter will be automatically inserted.

Base Metal: Enter the base material used in the test. This is the metal or alloy that is welded, brazed, or cut. Most related fields will be automatically completed if the material is selected from the Material Browser. Selecting a material as the "Base Metal 1" will select that material for "Base Metal 2" as well. However, another material may then be selected or entered independently for either field. The material with the lowest P- or S-Number should be entered first, as should an unrated metal.

PBHT (QB-409)

PBHT type: Indicate whether any post brazing heat treatment was performed. For P-No. 101 and P-No. 102 base metals, indicate the type of PBHT used.

PBHT temperature: Enter the temperature of the post brazing heat treatment.

PBHT holding time: Enter the actual PBHT time. This should be expressed in hours and decimals; for example, record a PBHT time of 4 hours and 15 minutes as 4.25.

PBHT notes: Enter additional notes about the PBHT that should be included with this BPQR.
