Re: [MW:31849] PWHT REQUIRED OR NOT?

Dear Ankit,

Normally Explosive Bonding will be performed at Plate Mill and any Heat Treatment if required will be performed at Mill and covered via the MTC.

SS 316 clad plates fall under SA 264 (ASME Sec.IIA). According to the same for Explosive bonding, the clad plate shall be subjected to solution Annealing and the substrate base plate carbon steel Heat Treated to the Material standard separately  prior to Explosive Bonding and can be checked in the MTC.

Thanks & Regards

Refering to SA264

HT is not mandatory for cladding process.

It's suplimentory requirement.

Dear Expert,

I hope all are well.

My question is In after Tubesheet Bonding PWHT required or Not?

Base Material : SA 516 GR 70. (Thk : 45 mm )

Bonding Material : SA 240 GR 316. (Thk:5mm)

Tubesheet Dia : 3000 mm

( Note : Bonding plate SS 316 : 1 No joint on base material)
