1. INTRODUCTION

The purpose of this document is to specify piping and station accessories materials

identification by color coding.

Identification for piping and station accessories materials is required since hazards

materials flow through this system. Then piping system should be appropriately labeled

to make people aware of the hazardous material they carry.

ANSI A13.1 – 1981 scheme for identification of piping systems addresses this concern

by offering a common labelling method to be used in all facilities.

In order to identify piping and station accessories materials, PGN has categorized

materials flow inside its facility as follows, then the color coding shall be determined

accordingly:

1. High-Hazard Materials

Materials included in this category is as follows:

Materials encompasses several hazard areas including corrosive and caustic

materials;

Substances that are toxic or capable of creating toxic gases; explosive and

flammable materials

Radioactive substances

Materials that, if released, would be hazardous due to extreme pressures and

temperatures.

2. Low-Hazardous Materials

Materials that are not inherently hazardous and have a small chance of harming

employees through mild temperatures and low pressures.

3. Fire Suppression Materials

Fire protection materials such as foam, carbon dioxide(CO2), Halon and water.

2. SCOPE

This document elaborate the color coding requrement for piping system with all its

accessories and equipments installed in station.

3. CODE AND STANDARDS

The following are international codes and standards being used in this color coding

identification for piping and station accessories materials requirement:

ANSI A13.1-1981 Scheme for the Identification of Piping System

ANSI Z53.1-1979 Safety Color Code for Marking Physical Hazards

ANSI Z535.1-1991 Safety Color Code

4. GENERAL RULES OF COLOR IDENTIFICATION

Pipe and its accessories marking labels must effectively communicate the contents of

the pipes and give additional detail if special hazards (such as extreme temperatures

and pressures) exist. The legend should be shorten in length and easy to understand.

An arrow should be used in conjunction with the legend to show which direction the

materials flows.

The following are the color-coded labels used in associated with their category as

mentioned earlier:

1. All high-hazard materials shall use black characters on a yellow background.

2. The low-hazard material class is divided into two different color shcemes as follows:

a. Liquid and liquid mixtures shall use white characters on a green background;

b. Gases or gaseous mixtures shall use white characters on a blue background.

3. The fire suppresion class shall use white letters on a red background.

The letters on pipe labels should be a minimum of ½” high, and should increase in size

as the pipe diameter increases.

4.1 Color Identification

All pipe in the piping system shall be identified according to their function or services and

their hazards source within. The identification shall be applied after the application of

insulation and/or final painting by color-coded banding and stenciling.

Marking shall inform the pipe material fluid and its direction also fulfilled with the

following requirement:

a. All markers shall be stenciled in positions visible to personnel. Marking shall conform

to pipe service identification (abbreviations) as noted on the drawings.

b. All Piping, both exposed and buried, shall be stenciled.

c. Paint pipe content banding, legend and flow direction marker at each valve, at every

point of pipe entry and exit where a line goes through a wall, on each riser and tee

joint, and at 25 feet interval on long continuous runs of pipe. Arrows (flow directions

marker) shall point away from content marking, and in direction of flow. If flow can be

in both directions, apply double-headed arrows.

d. Background Banding (paint)

Background banding for piping system and its accessories shall meet the following
