Subject: [MW:13963] TENSILE TEST REQUIRMENT FOR PLATES AFTER SIMULATION HEAT TREATMENT

Dear All,

 

A vessel is being fabricated as per ASME SEC VIII DIV 1.

 

 

Contarctor has received 3 plates ( SA 516 GR 70 N - 30 mm Thk) which are having one heat number and 3 different Plate No. Plate condition - Plate Hot Rolled. plate manufacturer has not done Simulation heat treatment of test coupon.

 

as per Client  Simulation  heat treatment ( 3 pwht cycle) is reuired. 

 

As per SA 20 PARA 11.1.1 One tension test is required for each plate as rolled. as per client requirment any mechanical testing shall be done after all heat treatment.

 

 

Please advice whether one sample from each plate has to undergo simulation heat treatment cycle & Tension test OR one sample out of any 3 plates shall undego simulation heat treatment & Tension Test.( as heat number is same for each 3 plates)

 

Please give code reference.

 

Thanks & Regards
