ASME A-106/A-106M Markings verification

ASME A-106/A-106M Markings verification

• ASME SA-106/SA-106M-2019 - Production Marking - Section 25
• ASME SA-530/SA-530M-2019 - production Marking - Section 24

Each length of pipe shall be legibly marked with (eg.)

• The manufacturer's name or brand: BCK.
• The specification number: ASME SA-106/SA-106M.
• Grade: B.
• Heat number: 3-35727.
• ASME SA-106/SA-106M - Table 4: NDE/2500 PSI.
• The length: 6000 MM.
• The OD: NPS 3".
• The Schedule: SCH XXS.
• The weight: not applicable for NPS 3".
• Supplementary: not applicable.

 

Note:

• This material do not cover welded pipe, see Section 1.1 of ASME SA-106/SA-106B.
• NPS 4" and larger shall marked weight class.
• Production analysis shall be made on the representative two pipes from each lot, see Section 9.1 of ASME SA-106/SA-106M.

 

Dimensional and visual inspection

• Forming/dimension/masses:  ASME B36.10M - 2018; ASME SA-530/SA-530M - Table X1
• Tolerance: ASMESA-530/SA-530M - Section 7, 8, 9, 10, 11, 12 - Table 1, 2, 3

 

Transfer markings, Guide to transfer markings information to a shorter length:

• Step 1: Verify MTC and pipe section are matched, dimensional / visual inspection for each pipe.
• Step 2: Transfer original markings to cut off length (unmarked cut length) by paint marker
• Step 3: Stamp "processor's name or trademark, brand (for resale) on both pipe segment.
• Step 4: Shot photo of the original markings and new transfer identification for preparing a report, photo report should minimum show all production markings, processor's identification, buyer name, date, signature, ... and attachment the MTC.
• Step 5: Cut the shorter length for resale by processor.

 

Coded markings

• Coded marking: Pxxxx - Pipe.
• Die stamp may be stamped on the thickness with T>= 6mm for carbon steel and  T>= 12 mm for stainless steel unless otherwise by supplementary requirements.
• Piping process fabrication may not required die stamp on the off-cut length.

 

End beveling preparations

• Accordance with the approved WPS.
• ASME B16.25 2017 - Fig. 1 through Fig. 6.

 

Storage pipe material

• Keep pipe material in dry area, keep away wet condition.
• All end pipes shall be protected by plastic covers.
