PART 1 GENERAL 1.01 SCOPE

A. Furnish all labor, materials, tools, and equipment necessary for process and utility sheet metal work shown on the drawings and specified herein.

1. Where the word "ducting" is used in this Section, and on the drawings, this shall be

interpreted to mean all process and utility sheet metal work.

2. Furnish and install flanges for ducting valves. The instrument air lines, electric wiring, etc., shall be furnished and installed by others.

3. Work not covered in this Section: Heating, ventilating, and air conditioning ducting.

1.02 DUCTING NOMENCLATURE

B. Drawings: Ducting work is shown schematically on the flow sheets and in detail on the mechanical equipment arrangement drawings.

1. Ducting Designations: The Drawings identify each duct unit with the following four-part

designations: 12MT2RD2

where: "12 is the outside diameter (in inches) of fabricated round ducting, "MT": is the service symbol for Malt. "2": is the individual ducting number. "RD2": is the sheet metal specification.

12 x 16EVlFD2

or 12 EV1 FD2

Where: “12 x 16” or “12”: are the outside dimensions (in inches) of fabricated rectangular ducting, or square ducting. "EV": is the service symbol for Explosion Vent. "1": is the individual duct number. "FD2": is the sheet metal specification.

2. Ducting shown on the flow sheets as a "dash-dot-dash" line indicates sheet metal furnished

as component parts of equipment supplied by the Owner.

3. Ducting Equipment Designations: The drawings identify each valve or specialty with a ducting equipment designation.

4. A three-part ducting equipment designation is assigned to items where individual

identification is required or where external power or control connections are required. An example is:

13XV521



MCS 23 13 13-2


where: "13"is the associated equipment group number. "XV": is the equipment designation for open-close valves. "521": is the individual open-close valve number.

PART 2 PRODUCTS 2.01 MATERIAL PROCUREMENT

A. General: Ducting materials shall conform to the gages and standards specified, shall be new, free of defects and imperfections, and shall be of recent manufacture. Material not covered by detailed specifications shall be standard products of reputable manufacturers and suitable for intended use.

1. Asbestos is prohibited in any item.

2. 23 13 13.01: This table lists the various ducting symbols, followed by the service

description. A ducting specification is given for each service.

3. Ducting specifications are divided into groups. These specifications give the minimum thickness in U.S. Standard gauge. Materials are specified by ASTM designations. Specific editions of standards incorporated in this specification by reference are shown in 23 13 13.03. Any materials furnished shall meet these standards. Applicable SMACNA sheet metal standards shall apply where specific reference is not made to other standards.

4. Applicable SMACNA Standards:

4.1. Accepted Industry Practice for Industrial Duct Construction. 4.2. Round Industrial Duct Construction Standards. 4.3. Classification of Industrial duct:

Class 1 includes non-abrasive applications: general ventilation systems and gaseous emission control systems.

Class 2 includes applications with moderately abrasive particulate: woodworking, grain dust.

Class 3 includes applications with highly abrasive particulate in light concentrations: dryers, kilns, boiler breaching, sand handling.

Class 4 includes applications with highly abrasive particulate in high concentrations: steel mills, mining, foundries, smelting.

Class 5 Applications with corrosives, such as acid vapors.

5. For exhaust system on corrosiveapplications, consideration shall be given to corrosive resistant materials or coatings.

2.02 GENERAL REQUIREMENTS

A. Match all ducting connections to equipment. Determine the connection dimensions from manufacturer's "certified prints" or from actual field measurements.

1. Galvanized construction shall not be used for temperatures exceeding 400˚F.

2. Rectangular ducts should be used only when clearance prevents the use of round

construction.



MCS 23 13 13-3


3. Unless otherwise specified, elbows and fittings shall be a minimum of 2 gauges heavier than straight duct length of equal diameter.

4. Unless otherwise specified, duct gages and reiforcement shall be in accordance with

SMACNA “Accepted Industry Practice for Industrial Duct Construction” Tables 1-A and 1-B for round duct construction and Tables 2-A and 2-B for rectangular duct construction. Thse tables are in four classifications of industrial duct.

PART 3 EXECUTION 3.01 INSTALLATION DETAILS

A. Accurately fabricate and install ducting or transitions in true alignment and within tolerances of the best practice for this type of work.

1. Impose no strain on equipment due to the misalignment of the ducting.

2. Fabricate ducting and transitions with butt welded joints using the latest methods,

techniques, and recommendations of the American Welding Society.

3. Flanged Connection: Where flanged connections are used to join individual sections, adjoining sections shall be butted squarely and bolted together with flanges continuously welded to the mating pieces inside, tack-welded outside, and spaced to allow adequate gasketing. Flange dimensions are given in Table 23 13 13.02.

4. Provide standard-type flexible connections, where shown on the drawings. Use materials

suitable for the service conditions and operating temperatures of connected equipment.

5. Elbows: Unless otherwise shown on the drawings, elbows shall be fabricated with a minimum centerline radius of two times the process sheet metal width in the turning plane for rectangular sheet metal, and on a minimum centerline radius of two diameters for round sheet metal.

6. Transitions: Provide transitions as shown on the drawings. Make minimum length of

transition equal to 1-1/2 times the larger rectangular dimension or diameter of the sheet metal.

7. Hangers and supports: Furnish and install all hangers, supports, guides, and auxiliary

supporting steel to properly and adequately support all ducting and ducting equipment.

8. Use structural-quality hot-dipped galvanized steel for support components. Connect support components to auxiliary supporting steel by bolting. Drill bolt holes and saw cut ends; do not use cutting torch. Bolt support components to concrete with expansion shields in pre-drilled holes. Do not use lead anchors. Shot-in anchors are not permitted.

9. Attach support components where they will not damage other construction. Use wall

brackets only where wall is suitable for support. No ducting shall be supported from equipment nor shall one duct support any other duct or item of equipment.

10. Provide openings for ducting through walls, floors, or roofs under this Section shown on the

drawings.



MCS 23 13 13-4


11. Clearance for valve discs in full open position shall be provided on each side of valves.

12. Provide 1" NPT capped drain coupling at low points of all wet service ducting.

13. Sealing of Ductwork.

exterior ducting. Other acceptable sealant are 3M 900, H.B. Fuller/Foster, Hardcast, Hardcast Peal and Seal, Lockformer cold sealant, and United Sheet Metal. Install sealant in strict accordance with manufacturer’s recommendations.

b. Gaskets: 2 inch pressure class or lower - Soft neoprene or butyl gaskets in combination

with duct sealant for flanged joints. 3 inch pressure class and higher and fume hood exhaust - butyl gaskets in combination with duct sealant for flanged joints.

3.02 CLEANING

A. All ducting and equipment shall be installed clean and free of grease, oil, mud, dirt, and construction debris. Take special precautions to prevent the entrance of foreign matter during the construction phases. Should foreign matter enter the ducting or equipment, disassemble, clean, and reassemble.

3.03. PAINTING

A. Contractor shall prime-paint all carbon steel ducting, hangers, supports, and auxiliary steel required by this Section with a universal primer (Porter 282 U-Prime or Glidden 5210 Fast Dry Metal Primer, 2 mils dry film thickness

3.4. ACCEPTANCE

A. Installation Acceptance: Request Engineer and Owner to make a visual examination of complete ducting installation. Repair any defects observed and request a new examination. Repeat procedure until the installation is accepted by the Engineer.

B. Final Operational Acceptance: Upon installation acceptance, perform an operational

demonstration at a time schedule satisfactory to the Engineer and Owner. The operational demonstration, witnessed by the Engineer and Owner, shall prove that all conditions of the Contract Documents have been fulfilled. If approved, a written acceptance notice shall be given by the Engineer. If rejected, make necessary corrections and repeat the operational demonstration until acceptance is obtained.
