Transcript of Color coding

Attachment 2- Color Coding and LabelingThe nature of the pipe contents shall be identified by means of a Three Band Colour Code Identification Band System , colors are as specified in Norsok DP-002 The outer bands, which will be the same color, are the Basic/Primary Identification Bands (PIB) and the middle band is the Safety/ Secondary Identification Band (SIB). The arrangement is shown in Figure 1.

Identification & Size The width requirements for the PIBs and SIB shall be the same for all pipe sizes over 6 diameter, with narrower band widths being used for pipe sizes varying from 2 to 6 diameter. The dimensions shall be as follows Table -1 Table -1

Pipe Diameter 2 to 6 inclusive Greater than 6

Each Basic/Primary Band 75 mm 150 mm

Safety/Secondary Band 50 mm 100 mm

Colour Coding Bands shall be provided on both sides of and adjacent to valves, tees, important fittings, wall entries and overpasses and outboard of flanges to and from equipment such as vessels, tanks, exchangers, compressors and pumps

Colour coding bands shall be provided at uniform intervals, not less than 30m and not more than 50m depending on the complexity and pipe run lengths, along horizontal and up vertical sections of pipework and at all feed points. Where multiple lines run close to each other, such as in common pipe racks, the line numbers and flow direction shall be located directly in line with one another at positions that are readily visible. For Valves, the full valve body shall be painted with the SIB for the relevant fluid group. The full Color code shall be applied both sides of the valve, to the adjacent pipework. For Control Valves, the valve bonnet and actuator or hand wheel /lever, shall be painted with one of the following two colours, to indicate whether the Control Valve is designed to fail open or fail closed as shown in figure 2 Fail Open Control Valves shall be painted Green, Fail Closed Control Valves shall be painted Red,

Content Labeling and Safety Warning Signs The additional use of Colored Labels giving the full or abbreviated product description, temperature, pressure, and other details necessary to identify any potential hazard, together with the appropriate visual aids and hazard pictorial symbols, is to be encouraged. Such labels and markings shall not, however, be considered as a substitute for the Color coding, whose application is considered mandatory. Where applied, labels shall be brief and informative and written in English. The text size for different pipe diameters shall be as specified in Table -2 The background colour of the label shall be similar to that of the appropriate PIB, ideally with appropriate SIB contrasting text colour,. The length of the labels shall vary from 200 to 800mm and they shall be applied adjacent to the CCIB locations. Labeling shall be in the form of painting or self-adhesive plastic labels. Plastic labels shall be of high performance type suitable for marine environment. Line Numbering In addition to being Colour Coded, each pipe system, pipeline and valve shall be individually identified by marking them in accordance with the BW Equipment Identification and Tag Numbering System, The required identification markings relate to pipe size, service, design, area code and ownership code. All characters used shall be in upper case. No separators, hyphens, punctuation marks or spaces are allowed. The line number and the flow direction shall be stenciled on each pipe section and pipeline together with the CCIB, to provide the pipework with unique traceability. The identification markings shall be stenciled on the pipe a distance of approximately 400 mm from the edge of the outer colour band. Letter size shall be equal to half of the pipe diameter for pipe between 2 and 12 diameter, with a minimum height of 1 for smaller pipe sizes and a maximum height of 6 for larger pipe sizes. Line identification markings shall be stenciled in black directly onto the light grey/white decorative background.
