Special requirements for HIC resistant materials"

[stamario]

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.
• DIM. STANDARDS: According to ASME 816.10.
* 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"
• PRESSURE RATING: Class 150
• MISCELLANEOUS: The gasket contact surface shall be formed by a phonographic or concentric finish.
• REMARKS: Man.LVF
• COLOR CODING: Blue

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

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

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.
