ASME BPVC 2023 Section II part B
New product
SPECIFICATION FOR UNS N08367 AND UNS N08926
WELDED PIPE
SB-804
Identical with ASTM Specification B804-022013 except that the following additional requirements apply, and certification
is mandatory.
All products furnished under the SB specification are intended for application under the rules of Section III of the ASME
Boiler and Pressure Vessel Code. Manufacture of such products is limited to manufacturers who hold the appropriate
ASME Certificate of Authorization and Certification Mark. In addition to conforming to this specification, the manufacturer
shall meet all applicable requirements of Section III of the Code. The plate used to fabricate the pipe shall conform to
SB-688. The joints shall be full penetration butt welds as obtained by double welding or by other means, which will obtain
the same quality of deposited and weld metal on the inside and outside. Welds using metal backing strips which remain in
place are excluded. The product is subject to all requirements of Section III of the Code including welding, heat treatment,
nondestructive examination, authorized inspection at the point of manufacture, and application of the Certification Mark.
The applicable ASME Partial Data Report Form signed by an Authorized Inspector and a certified mill test report shall be
furnished for each lot of pipe. The term “lot” applies to all pipe of the same mill heat of material and wall thickness which is
heat treated in one furnace charge. For pipe that is not heat treated, or that is heat treated in a continuous furnace, a lot
shall consist of each 200 ft 61 m or fraction thereof of all pipe of the same mill heat material and wall thickness subjected
to the same heat treatment. For pipe that is heat treated in a batch-type furnace that is automatically controlled within a
50°F range and is equipped with recording pyrometers so that the heating records are available, a lot may be defined the
same as for continuous furnaces. Each length of pipe shall be marked in such a manner as to identify each such piece with
the lot and the certified mill test report.
