BASIC PIPING MATERIAL AND METHODS 15055-1
SECTION 15055
BASIC PIPING MATERIALS AND METHODS
PART 1 - GENERAL
1.1 RELATED DOCUMENTS
A. Drawings and general provisions of Contract, including General and Supplementary Conditions
and Division 1 Specification sections, apply to work of this section.
1.2 SUMMARY
A. This Section specifies piping material and installation methods common to more than one section
of Division 15 and includes joining materials, piping specialties, and basic piping installation
instructions.
1.3 QUALITY ASSURANCE
A. Welding procedures and testing shall company with ANSI Standard B31.1.0 - Standard Code for
Pressure Piping, Power Piping, and The American Welding Society, Welding Handbook.
Soldering and Bracing procedures shall conform to ANSI B9.1 Standard Safety Code for
Mechanical Refrigeration.
1.4 SUBMITTALS
A. Product Data
Submit manufacturer’s technical product data and installation instructions for each sealant
material required.
1.5 EXISTING CONDITIONS
A. It shall be the responsibility of the Contractor to field verify the existence and location of
underground utilities in the vicinity of their work. Omission from, or inclusion of, utility locations
within the Contract Documents is not to be considered as the nonexistence of, or a definite
location of, existing underground utilities. The Contractor will take all necessary precautions to
protect existing utilities from damage due to his operations. Any damage to existing utilities shall
be repaired at the Contractor’s expense.
PART 2 - PRODUCTS AND MATERIALS
2.1 PIPE AND FITTINGS
A. Refer to the individual piping system specification section in Division 15 for specifications on
piping and fittings relative to that particular system.
2.2 JOINING MATERIALS
A. Welding Materials shall comply with Section II, Part C, ASME Boiler and Pressure Vessel Code
for welding materials appropriate for the wall thickness and chemical analysis of the pipe being
welded.
B. Brazing Materials shall comply with SFA-5.8, Section II, ASME Boiler and Pressure Vessel Code
for brazing filler metal materials appropriate for the materials being joined.
C. Soldering Materials shall refer to individual piping system specifications for solder appropriate for
each respective system.

D. Fire Barrier Penetrations shall sealant shall be Dow Corning #2000 Fire Stop Sealant (Gray), or
3M CP-25 Sealant, or approved equal.
E. Sound Barrier Penetrations sealant shall be PL Acoustical Sealant as manufactured by CEM REX
or approved equal.
F. Smoke Barrier Penetrations sealant shall be Dow Corning #2000 Fire Stop Sealant (Gray), or 3M
CP-25 Sealant, or approved equal.
G. Exterior Wall Penetrations shall be sealed per the Architectural Specifications.
PART 3 - EXECUTION
3.1 INSTALLATIONS
A. Mechanical drawings (plans, schematics, and diagrams) indicate the general location and
arrangement of the piping systems. Location and arrangement of piping layout take into
consideration pipe sizing and friction loss, expansion, pump sizing, and other design
considerations. So far as practical, install piping sized as indicated on the drawings.
B. Conceal all pipe installations in walls, pipe chases, utility spaces, above ceilings, below grade or
floors, unless indicated otherwise. Install piping free of sags or bends and with ample space
between piping to permit proper insulation applications. Install exposed piping at right angles or
parallel to building walls. Diagonal runs are not permitted, unless expressly indicated on the
Drawings. Install drains at low points in mains, risers, and branch lines. Install piping tight to
slabs, beams, joists, columns, walls, and other permanent elements of the building. Provide
space to permit insulation applications, with 1” clearance outside the insulation. Allow sufficient
space above removable ceiling panels to allow for panel removal.
C. Fire Barrier Penetrations: Where work performed under Divisions 15 passes through fire rated
walls, partitions, ceilings, or floors, the fire rated integrity shall be maintained. Fireproofing
sealants shall be installed as recommended by the manufacturer to obtain the fire-rating required.
D. Sound Barrier Penetrations: Where work performed under Divisions 15 pass through sound
barrier walls, partitions, ceilings or floors, the sound integrity shall be maintained. Sound barrier
sealant shall be installed as recommended by the manufacturer.
E. Smoke Barrier Penetrations: Where work performed under Divisions 15 pass through smoke
rated walls, partitions, ceilings or floors, the smoke rated integrity shall be maintained. Smoke
sealants shall be installed as recommended by the manufacturer.
F. Exterior Wall Penetrations: Where work performed under Divisions 15 pass through exterior
walls, sealants and materials shall be installed as recommended by manufacturer and as per
Architectural Specifications.
3.2 FITTINGS AND SPECIALTIES
A. Use fittings for all changes in direction and all branch connections. Install unions adjacent to each
valve, and at the final connection to each piece of equipment and plumbing fixture having 2” and
smaller connections, and as otherwise required to facilitate proper maintenance. Install flanges in
piping 2-1/2” and larger, adjacent to each valve, and at the final connection to each piece of
equipment, and as otherwise required to facilitate proper maintenance. Install dielectric unions to
connect piping materials of dissimilar metals.

3.3 JOINTS
A. Steel Pipe Joints
1. Steel Pipe Joints 2” and Smaller
Provided threaded pipe with tapered pipe threads in accordance with ANSI B2.1. Cut threads
full and clean using sharp dies. Ream threaded ends to remove burrs and restore full inside
diameter. Apply pipe joint lubricant or sealant suitable for the service for which the pipe is
intended on the male threads at each joint and tighten joint to leave not more than 3 threads
exposed.
2. Steel Pipe Joints Larger Than 2”
Provide welded pipe joints (except for exterior water service pipe) in accordance with ASME
Code for Pressure Piping, B31. Install flanges on all valves, apparatus, and equipment. Weld
pipe flanges to pipe ends in accordance with ASME B31.1.0 Code for Pressure Piping.
3. Non-Ferrous Pipe Joints
For copper tube and fitting joints, braze joints in accordance with ANSI B31.1.0 - Standard
Code for Pressure Piping, Power Piping and ANSI B9.1 - Standard Safety Code for
Mechanical Refrigeration.
