GENERAL NOTES:
(a) Organic zinc rich primer (in compliance with ISO 12944-5 paragraph 7.1.2) is an alternative
to ESI
(b) For items requiring extended welding/construction activities at site (e.g. fired equipment, API
tank, etc.), evaluation shall be made on case by case basis. The general philosophy is the following:
-
Application of weldable temporary primer on areas (cutback) which will be damaged by welding operation (surface preparation as per Paint Manufacturer recommendation)
-
Surface preparation and application of definitive (in accordance with above table)
primer on areas not affected by welding If the ratio between surface requiring temporary primer and surface requiring definitive primer is high (e.g. above 15 – 20%) the entire surface shall be protected with temporary primer.
PARTY shall submit in its bid detailed proposal (in table format) about kind of protection (status of supply: e.g., temporary primer, definitive primer or other) proposed for each single piece along with information about presence of insulation/max expected skin metal temperature.
(c) Any paint shall be suitable at the max operating temperature of the item on which is applied.
Steam out condition shall be considered at 120 °C as maximum temperature.
(d) The critical items having special design (e.g.: reformers, transfer line etc..) may have specific notes about painting requirements also on datasheet/G.A. Drawing. Such cases shall be highlighted by Vendor and bring to the attention of Contractor for resolution. As general philosophy: the surface preparation and painting systems indicated in this specification cannot be relaxed; any additional requirement indicated on datasheet/G.A. Drawing (e.g.: temperature indicating paint, additional paint for stainless steel) shall be considered.
(e) The maximum permissible VOC (Volatile Organic Compound) and toxic metals (such as lead, chromium, cadmium, etc.) shall be in accordance with local law and regulation (at workshop location). PARTY is full responsible for selection of suitable product in compliance with local requirements and regulations.
(f) Not insulated hot dip galvanized steel, Aluminum and other non-ferrous materials shall be
painted only when required for aesthetic or signaling reasons.

GENERAL NOTES:
(a) For items requiring extended welding/construction activities at site (e.g. fired equipment),
the painting systems shall be applied as follows:
areas with weldable temporary primer: removal of contaminants as per SSPC-SP 1, complete removal of temporary primer. Surface preparation and applicable painting system as per Table 5 areas with definitive primer: removal of contaminants as per SSPC-SP 1. Touch-up of primer and application of intermediate / finish coat of the applicable painting system as per Table 5
(b) any different painting system applied on critical items shall be repaired as follows: surface preparation as SSPC-SP 1 and SSPC-SP 3 (or stringer requirement indicated on the technical datasheet); re-application of the original painting system starting from primer. (c) Organic zinc rich primer (in compliance with ISO 12944-5 paragraph 7.1.2) is an alternative
to ESI.
(d) Not insulated hot dip galvanized steel, Aluminum and other non-ferrous materials shall be
painted only when required for aesthetic or signaling reasons.
(e) The selected paint shall be suitable at the maximum operative temperature of the item on
which is applied.
(f) Primer, if required by selected intermediate, shall be compatible with the intermediate and
its minimum dry film thickness shall be as per product datasheet/PM’s recommendations.
