SCOPE

This Standard describes the requirements for colour coding of metallic pipework for identification of fluids and services in above ground installation at new and existing KOC facilities. It also includes the requirements for colour coding when insulated or non-metallic pipes are used.

GENERAL / APPLICATION

Colour coding materials, application method and inspection & testing shall conform to the requirements of this Standard and the reference Standards 1 Codes.

Any exception or deviations from this Standard, along with their merits and justification, shall be brought to the attention of KOC's Controlling Department, for their review, consideration and amendment by Standards Division ( if required ).

REFERENCE CODES AND STANDARDS

In the event of conflict between this Standard and the Standards1 codes referenced herein, the most stringent requirement shall apply, unless otherwise specified. KOC reserves the right to identify the applicable requirement(s) in such cases.

List of Standards and Codes

The latest edition of the following standards and codes shall apply:

BS 1710 Identification of Pipelines and Services.

BS 4800 Paint Colours for Building Purposes.

KOC- G- 007 KOC standard for Basic Design Data.

KOC - P- 001 Painting & Coating of Metal Surfaces - New Construction

ENVIRONMENTAL CONDITIONS

The environment of Kuwait is severe on all equipment and structures and must be considered carefully before the selection of colour coding material. It must be assumed that, unless otherwise specified, colour finish coat may be subjected to sand and fine particle dust storms, salt laden winds, chemical contaminants and extreme temperatures.

KOC Standard for Basic Design Data, KOC-G-007, provides the detailed design information regarding the environmental, site and utility supply conditions prevailing throughout the KOC facilities/ works which shall be compiled.

HEALTH, SAFETY AND ENVIRONMENT

All necessary health and safety procedures to protect personnel and surrounding environment shall be followed during on-site surface cleaning and application of identification colours.

All relevant safety requirements of the KOC Fire & Safety Regulations and the KOC's HSE policy shall be strictly adhered to for all works performed within KOC operation areas.

COLOUR IDENTIFICATION MATERIALS

Quality of Materials

All paint materials used for colour identification shall be chemically pure, uniform in composition and free from foreign contaminants.

Colour identification paidt materials shall not contain any toxic or hazardous constituents (e.g., Asbestos, Red Lead, Lead Chromate) .

Paint materials used for colour identification shall be specially made for colour coding purposes.

All paint materials shall be oikhemical resistant, abrasion resistant and capable of withstanding an application temperature as per the site conditions

of KOC facilities mentioned in KOC-G-007, and a service temperature as per the pipe design requirement.

Approval

The supplier's submittal for colour identification materials shall include details of manufacturer, generalized composition, technical specification, physical properties and laboratory testing certificates for the materials t o be used.

The colour identification paint material shall be compatible w i th the pipework protective coating.

The identification colours t o be used shall be in accordance wi th BS 4800 , Paint Colours for Building Purposes, and as specified in this Standard.

COLOUR CODING APPLICATION

General Requirements

Colour coding paint shall be applied on dry and clean pipe surfaces. Foreign materials like deposits, oil, grease, dustlsand and any other foreign material shall be removed by a suitable and approved method.

Colour coding paint shall be spray applied t o the specified area(s). Hand or roller application can be used for areas which can not be properly sprayed. The application shall be in accordance wi th the paint manufacturer's recommendations.

The minimum DFT of colour coding coat for new construction pipework shall be as specified for the finish coat in the painting schedules of KOC-P-001. For insulated, non metallic and existing metallic pipework, the DFT of colour coding coat shall not be less than 40 micron.

METHODS OF APPLICATION

Two methods of colour identification of pipe contents and services are adopted in this Standard. These are mainly based on the principles and guidelines of BS 17 10. The following clauses explain these methods.

Base Colours Only

a) Where only identification of the basic nature of the fluid is required, the base colour shown in Table 1 shall be applied by painting it over the whole length of the pipework including valves, flanges, etc. For

example, if the pipework content has been coded for fire fighting, the whole pipe length and all valves and flanges shall be painted red. Appendix 1, Figures 1.1 t o 1.3 explain this method of colour identification.

For pipework were protective coating is not required e.g., FRP pipes, stainless Steel pipes, insulated pipes, ... etc, and for cases where painting the base colour over the whole existing painted pipe is not required for operational or economical reasons, the base colour can be painted on the pipe as a band over a length of about 150 m m for up t o 6 inches (1 50 mm) pipe; for pipe diameters greater than 6 inches, the length of the band shall be approximately pipe diameter.

The colour band shall be applied at intervals of 5 meters along the pipe and at junctions, both sides of every valve, inlet and outlet of every piece of equipment or vessel, wall penetration and any other place where identification is necessary.

8.2.2 Base Colours and Indication (Band) Colours

a) The base colours only designate broad groups of fluids. It may be necessary t o break these groups down further depending upon fluid type /function, e.g. the base colour for identification of all oils1 hydrocarbon fluids is brown, but it may be necessary t o differentiate between we t crude, dry crude, condensate oil, etc. In such cases the base colour shall identify the prime nature of the pipe contents with an indication colour(s) painted as a band t o identify more precisely the fluid. Table 2 explains

the base colours in conjunction with indication (band) colours for various types of fluids.

The indication colour band shall be painted over the base colour, described in para. 8.2.1 (a),, round the complete circumference of the pipe at points specified in para. 8.2.1 (c). The minimum band length shall be approximately 150 mm for up to 6 inches (1 5 0 mm) pipe diameters, for pipe diameters greater than 6 inches, the band length shall be approximately pipe diameter. Figures 2.1 to 2.3 of Appendix 2, show examples of this case.

For cases where t w o indication colours are required, t w o joint indication colour bands shall be painted over the base colour at points specified in para. 8.2.1 (c). The length of each band shall be as mentioned in para. 8.2.2(b). Figures 2.4 to 2.6 of Appendix 2 show examples of this case.

For pipework conditions mentioned in para. 8.2.1 (b), the base and the indication colour(s) can be painted on the pipe as three bands over the pipe surface round the complete circumference of the pipe at points specified in para. 8.2.1 (c). The outside bands shall be the base colour and the centre band may be of one or combination of colours. The length of each band shall be as mentioned in para. 8.2.2(b). Figures 3.1 to 3.3 show examples of this case and the dimensions of the colour bands.
