ASTM A234 WPB instead of A106 Gr.B SMLS?
ASTM A234 WPB instead of A106 Gr.B SMLS?
(OP)
Dear all,
I have material certificates of the following accesories:
2 x 1 1/2 ECC. SWAGE NIPPLE BEXPE Sch.80
1 1/2 x 1 ECC. SWAGE NIPPLE PBE Sch.80
1 1/2 x 1 CONC. SWAGE PBE Sch.80
1 x 3/4 CONC. SWAGE NIPPLE PBE Sch.80 X 160
They have deliverey us in ASTM A-234 WPB instead A-105 Gr.B (SMLS) (required by the owner)
Could I accept this change of material?
The two qualities are good for high temperature, chemical composition is better in A-234 and mechanical propieties too
Could I?
Many thanks

ASTM A-53, Gr. B
ASTM A106, Gr. B,
There are others but above is most common.
then,
ASTM A-234, Gr. WPB is the normal wrought fitting specification for Reducers, BW Elbows, Welding Tee's etc.
ASTM A-105 is the normal forged fitting specicfication for flanges, Socket-welded and threaded tee's, couplings, etc.
In spite of problems with the owners specification, it looks like you got the the correct materail.
