Special requirements for HIC resistant materials"

Special requirements for HIC resistant materials"

(OP)
Helo;

I need to order some HIC resistant Gate valves, there is example:

50.06-CA075 * GATE VALVE    VENDOR'S DEVIATIONS. * DESCRIPTION: Solid wedge, bolted bonnet and gland, back seat, o s y and r.st., reduced bore with renewable or integral seat
• DESIGN: According to API 602.

* END CONNECTIONS: Raised Face, smooth finish (125-250 cla).
• MATERIALS: Body and bonnet: A105, trim: A182 grade F316, bonnet gasket:
spiralwound, SS-graphite filled, packing: braided graphite filament with
inconel wire and corrosion inhibitor, bolts/nuts: A193 grade B7 - A194 grade 2H. • STATE OF SUPPLY: HIC Resistant; fully in accordance with the "Special
requirements for HIC resistant materials"
• CERTIFICATES/REPORTS: Conform "The Technical Specification"

my question is what means "fully in accordance with the Special requirements for HIC resistant materials"
where I can find those special requirments?
Or can someone tell me how to make that order for those valves, and also for NACE valves?
Thanks

RE: Special requirements for HIC resistant materials"

in the oerder is clearly stated that the valves shall be compliant with the requirements of NACE /ISO 15156 for Sour Service?

RE: Special requirements for HIC resistant materials"

First of all, you may have to confirm the P.O requirements as below.

1. Applicable Codes and Standards in P.O spec. – such as NACE MR0175/ISO 15156, NACE MR0103, NACE Publ. 8X194, EEMUA, etc.
2. Company (Client's) Standard : wet sour service spec, etc.

If the P.O requirement is only mentioned as a HIC resistance steel, you have to confirm the applicable codes or specification to your client because the definition, requirements (materials and fabrication), test methods/procedures, and acceptance categories of HIC resistance are various per code or spec.
