technical and
is
For the bolts, nuts, studs, fasteners or mechanical fixation accessories within scope of equipment, the coating requirements indicated in this Appendix E does not supersede the coating indicated within the functional or technical data sheet of the specific equipment.
Unless clearly indicated otherwise in project functional specifications, the coating herein described is applied mainly for anticorrosion purpose, following the material selection philosophy indicated in doc. ‘200-20-CE-DEC-00006’; moreover lubricity purpose (in order to reduce the friction during tightening) is also considered.
This section is not intended to cover on metallic fasteners belonging to subsea structures and equipment, which are outside the fixed facility battery limits; coating requirements considered in for subsea structures are dealt separately in doc.’200-20-PL-SPC-00044’
E.2
COATING SYSTEM
Carbon and Low-Alloy Steel bolts, studs, nuts and washers shall be coated before assembly, for the purpose of lubricity and corrosion protection as per the coating characteristics method specified hereafter.
Fasteners belonging to piping and structural pertaining to topside deck, service exposed to marine atmosphere, shall be provided with conventional zinc/nickel plating basecoat, which provides corrosion resistance; the zinc/nickel base coating shall be constituted with 11% to 15% nickel and 85% to 89% zinc. Moreover an additional fluoropolymer topcoat is intended to reduce torque-up friction.

• Washers:
Washers shall be coated with the same basecoat and topcoat designated for the nuts and studs. The designated coating system shall be compatible with circular hardened steel washers per ASME PCC-1, Appendix M “Washer Usage Guidance and Purchase Specification for Through-hardened Washers” or Company-approved equivalent.
• Nuts:
Nuts shall be coated with the same basecoat and topcoat designated for externally threaded parts: conventional zinc/nickel plating requires overtapping of the nuts to accommodate the specified coatings and assure that specified nut/stud fit during assembly for delivery and during final assembly. Vendor shall provide nuts that turn freely (manually) on the corresponding externally threaded part at delivery and to convey with the nut supplier any overtapping criteria necessary to ensure free nut run-up following the coating process.
• Double-end Studs
The double-end studs and round stock (unthreaded portion of a bolt) shall be coated simultaneously with the threaded studs of the same diameter and subjected to identical production processing
• Stud bolts
In case coating is required stud bolts shall be coated with Zn-Ni electroplating basecoat and fluoropolymer topcoat.
E.3
COATING APPLICATION
The coating work shall be performed by Company-approved Applicators. The requisite data submittals include the testing indicated hereafter in this Appendix E. Company may elect to consider pre- existing test reports that are comparable to the test criteria mentioned hereafter. All coated fasteners shall have traceability as to the origin of the fastener and coating.
Coatings shall be applied when the surface of the parts being coated is at least 5°F (3°C) warmer than the ambient dew point temperature and the ambient air temperature is between 55°F (13°C) and 90°F (32°C), unless documented approval of less strict criteria has been promulgated by Coating Manufacturer and approved by Company.
The parts shall be visibly dry and at a surface temperature of not more than 125°F (52°C) prior to coating.
• Zinc/Nickel Basecoat
Immediately following the final cleaning of the fasteners (as per coating application guidelines and Manufacturer recommendations), zinc/nickel alloy shall be electrodeposited out of an alkaline electrolyte to achieve a minimum of 15 μm of plating thickness. In addition, a trivalent chromate conversion coating post-treatment shall be applied.
Visual examination of the conversion coated parts, unaided or with magnification ≤ 5x shall show a uniform appearance free from spots, uncoated areas, powder, and white residues.

INSPECTION REQUIREMENTS
Coating Applicator shall document and maintain a Quality Control Program (QCP) approved by Coating Manufacturer, which shall be always available for review and approval by Company during working hours. The QCP shall capture the array of coating material batches applied under a given job code.
The QCP shall include or reference a Company-approved Coating Application Procedure (CAP) expressly addressing each of the process steps involved in the performance of the coating work.
The CAP shall include the stepwise Quality Control (QC) records to be established and maintained throughout the coating work process. The results of the four tests described below shall be made part of the QC records. All QC records pertaining to the coating work shall indicate both Fastener Supplier’s job code and that of Coating Applicator.
Basecoat thickness shall be measured to confirm that thickness is achieved before release to the next coating process. To measure the thickness, X-ray spectroscopy (per ASTM B 568) shall be used. The plating thickness measurement shall be witnessed by COMPANY/ EPC CONTRACTOR in accordance with CAP.
E.6
PRODUCTION TESTING
The following QC testing shall be completed prior to shipping. Failure to comply with the acceptance criteria of any test shall be cause for rejection of the lot. Testing of washer coatings is not required. Methods described in ASTM D 6677 may be modified to allow smaller X-cut to fit part.
• Coating Cure: Determine the adequacy of the topcoat’s cure per ASTM D 5402
• Coating adhesion: Assess coating adhesion per ASTM D 6677 (smaller X-cut to fit part). The
acceptance criterion for coating adhesion is that the coatings shall have a rating > 8.
• Hardness testing of cured coating: perform hardness testing per ASTM D 3363. The acceptance criteria shall be provided in Coating Manufacturer’s Product Data Sheet or Company-approved equivalent.
• Coating thickness: Determine the DFT of each coat and the overall DFT achieved on the sample parts. Minimum thicknesses shall be for “significant surfaces” as defined in ASTM F 1941/F 1941M, Figure 1 “Significant Surfaces on Externally Threaded Fasteners” and Figure 2 “Significant Surfaces on Internally Threaded Fasteners and Washers.”
DFT assessment of externally threaded surfaces shall be made visually by means of microscopic examination of resin-mounted, sectioned, polished, and natal-etched fasteners. The mounting resin shall bond perfectly when sectioned and not lift from the coating. The mounting resin color shall allow clear differentiation between the potting and the coatings. Magnification shall be 50x to 100x. An electronic file-type photomicrograph shall document each examination. Each photomicrograph shall contain a scale in μm.
Externally threaded fasteners (studs and bolts) shall be ground or milled as necessary, to achieve longitudinal sectioning over a length of at least 0.8 in. (2 cm). The temperature shall not exceed 350°F (177°C) during the sectioning process. Sectioning shall confirm that the thickness of each of the two coatings comprising the system and the combined two coats meets or exceeds the minimum thickness indicated in Table 5-1.

COATING SYSTEM PRE-QUALIFICATION
In case basecoat are performed by applicators that are not currently included in Company approved list, the following pre-qualification test shall be performed and test report shall be submitted to Company for approval:
• Salt fog exposure performance testing as per ASTM B117
Coating Applicator shall prepare fastener test specimens that represent the coating system(s) that is (are) to be applied. For each different coating system to be tested, the salt spray test shall be carried out on two sets of four coated test studs, each with a coated pair of nuts and washers.
For testing purpose, test studs shall be any diameter from ½ in. to 1½ in. (12.7 mm to 38.1 mm); stud length shall be as required to satisfy the flange size/geometry; the thread projection shall not be large enough as to interfere with the tightening socket.
The coated fasteners to be tested shall be selected by the test facility and shall have a range of fits as judged by the ability to turn the nuts by hand; “X” scribe opposite faces of both nuts on a given stud per ASTM B 117.
Each of the two groups of four test studs, nuts, and washers shall be fitted to separate flange assemblies comprised of a pair of raised-faced Fiber-Reinforced Plastic (FRP) piping flanges, ASME B16.5 Class 150#; fasteners shall be arrayed symmetrically around the bolt circle. FRP flanges shall be fabricated from material complying with API SPEC 15LR, each flange pair shall bear a unique, indelible Inside Diameter (ID). A gasket shall be provided that conforms to the requirements of ASME B16.21; the gasket material shall not contain metallic fillers. The flange thickness shall be selected to ensure that, when snug, and accounting for the gap due to the raised faces and gasket, nuts are threaded onto the stud at least one nut width across the flats (i.e., so that the thread stick-out is at least one nut in width).
The nuts for one of the two flange pairs shall be tightened such that the net stud elongation is as required to produce stress equal to 105 ksi (724 MPa), the 0.2% offset yield per ASTM A 193/A 193M, Table 2 “Mechanical Requirements–Inch Products” for Grade 7; the nuts for the second flange pair shall be finger-tight only; stud tensioning shall be by means of a manual socket wrench.
During the salt fog exposure the pair of flanges shall be placed within the salt spray cabinet. One flange shall be oriented vertically and the other flange shall be oriented horizontally; the test report shall note, by reference to the flange ID, how a particular flange assembly was oriented. After 3,000 hours of exposure, the extent of rust on two or more coated nuts or studs shall not be inferior to Rust Grade 5 per ASTM D 610 to constitute a passing exposure test; it shall be verified that the nuts can be removed from the studs with a hand torque;
