FIELD RE-ROUTING TO CLEAR INTERFERENCES

28.1. Proper planning and checking has been done by the Owner's Representative to minimize, as far as possible, any interferences or conflicts between new piping and new or existing construction. However, prior to beginning the erection of each line, the Contractor shall use every practical means to ascertain that no such interferences will be encountered, thereby precluding the necessity of disassembling partially or completely erected systems for rerouting to clear obstructions which may exist. Where any interference is thus determined as existing, the Contractor shall obtain the approval of the Owner's Representative for a corrected routing to clear the interference in the most economical and satisfactory manner. After such approval has been obtained, and only then, the Contractor may proceed with erection as approved. Where such authorized re-routing involves the use of extra materials, the Contractor may submit his request for the cost of the material and its installation only to the extent that it exceeds the quantities required for the routing as originally shown on drawings. 28.2. In no case shall the Contractor be entitled to extra compensation for "taking down" or dismantling work which has been erected or prefabricated except for such prefabrication as has been called for in this specification or on the drawings, or unless otherwise specifically authorized in writing by the Owner's Representative.

31.2. Labeling. Pipe labeling is used to identify the contents of pipes, to denote pressure and temperature hazards as a part of the legend when appropriate, and to indicate direction of flow. 31.3. Color Coding. Color coding is used to identify the degree of hazard posed by the chemical or physical properties of the pipe contents. It also denotes the use or function of the piping system in the case of fire protection piping. 31.4. Type of Labels. Pipe labels shall be as manufactured by the W. H. Brady Company, P. O. Box 571, Milwaukee, Wisconsin 53201, phone number (414) 358-6600, or as approved by the Owner's Representative. The "Snap-On" or "Self-Sticking" (adhesive backed) markers are the preferred type for labels. 31.5. Label Size. The size (height) of the letters and the minimum length of the label (field) shall be based on the outside pipe diameter, including insulation and jacketing, if any. If multiple pipes are bundled and wrapped, the determining factor is the approximate outside diameter of the bundle. Outside Diameter of Pipe or Covering (Inches) Less than 1-1/2 1-1/2 to 2 2-1/2 to 6 8 to 10 Over 10

GENERAL PIPING SPECIFICATIONS (31.0 - PIPING IDENTIFICATION AND COLOR CODING – continued) 31.7. Directional Arrows. The direction of flow through a pipe shall be indicated by the use of directional arrows displayed as part of the label. When the application is suitable, the arrows shall be preprinted on the banding tape used to secure each end of the label, and the tape shall cover the complete circumference of the pipe, including insulation (W. H. Brady - "SYSTEM 1"). 31.8. Color Selection Guidelines. The following outlines the general criteria for color selection; (Specific assignments are made in the next paragraph): 31.8.1.

Green. Reserved for liquids which have a low degree of hazard. For a liquid to qualify in this category, it must have no chemical or physical properties which are considered hazardous and must be at a temperature less than 125°F and a pressure less than 150 psig. (NOTE: Water need not be of a potable purity to qualify in this category; it may contain chemical or biological contaminants as long as the concentrations present are considered a low hazard.)

31.8.2.

Blue. Reserved for gases which have a low degree of hazard. For a gas to qualify in this category, it must have no chemical or physical properties which are considered hazardous and must be at a temperature less than 125°F and a pressure less than 150 psig. Compressed air does not have to be breathable to qualify in this category because this guideline assumes that the use of plant compressed air for breathing and life support is prohibited.

31.8.3.

Yellow. Reserved for steam, condensate, gases, vapors, liquids and pneumatically-conveyed solids which, due to their chemical or physical properties, are hazardous. This includes any pipe with contents at a temperature of 125°F or greater or at a pressure of 150 psig or greater. Also reserved for multiple pipes bundled together.

31.8.4.

Red. Denotes fire protection or fire quenching systems. This includes water, steam snuff, halon gas and carbon dioxide systems if these systems are dedicated for fire protection or fire quenching. Steam, water, or carbon dioxide systems for other purposes do not qualify in this category.

31.9. Color Assignments. All piping systems shall be identified with labels having fields color coded in accordance with the above degree of hazard criteria or the color assignment (when given) for each service in the Piping Service Index, Section 2.01 of this specification. Multiple pipes bundled together inside a common wrapping shall be treated as hazardous and color coded "yellow". 31.10. Temperature Hazards. Any pipe which conveys a material at an operating temperature of 125°F or greater shall be considered a temperature hazard. The label wording shall start with the word "hot" to denote the temperature hazard unless the label wording adequately conveys the temperature hazard without the use of this word. An example of a label wording that does not require use of the word "hot" to indicate temperature hazard is "steam". 31.11. Pressure Hazards. Any pipe which conveys a material at an operating pressure of 150 psig or greater shall be considered a pressure hazard. The label wording shall include the words "high pressure" or the nominal pressure value (e.g., "150 psig"). 31.12. Pipe Bundles. Multiple pipes wrapped to form a bundle shall be labeled "Caution: Multiple pipes under pressure". 31.13. Multiple Use Pipes. When a pipe is used to convey various materials at different times, it shall be labeled as follows: 31.13.1. Similar Materials. If the various content materials are similar in their physical and chemical properties and present a similar type and severity of hazard, then the label wording shall be a generic or general name which describes all the various materials. Examples are "resins", "polymer" and "oil". The general name used for labels shall be approved by the Owner's Representative. 31.13.2. Dissimilar Materials. If the various content materials are dissimilar in their physical and/or chemical properties and present differing types and/or severities of hazards, then the label wording shall begin with the phrase "This pipe may contain" followed by the list of each of the various materials which might be conveyed.

Use points include but are not limited to: connections to equipment, machinery, tanks, vats, sumps, wet wells and hose stations. This applies to both indoor and outdoor use points. 31.16.2. Potential Use Points. A label shall be placed at each potential use point, including abandoned pipes and abandoned valves, unless said potential use points are permanently capped or plugged and valves are locked shut. This applies to both indoor and outdoor potential use points. 31.16.3. Transition Points. A label shall be placed at each point where a pipe enters or surfaces from the ground. A label shall be placed on a pipe on both sides of an intersection with a wall, floor, roof or ceiling. This includes both indoor and outdoor locations. 31.16.4. Main and Headers. Labels shall be placed on pipe mains and headers at a suggested spacing of 50 feet, not to exceed 100 feet. Labels shall also be placed on mains and headers at all valves, adjacent to changes in direction, and at all branch or tee connections. Additional labels shall be used on mains and headers to compensate for disrupted or obscured visibility due to structures, poor lighting or other reasons. 31.16.5. Miscellaneous Valves.
