PART 3 EXECUTION
3.1 INSTALLATION, GENERAL
Installation of steel pipes and fittings shall comply with
requirements of the Division 15 Sections.
3.2 JOINTS CONSTRUCTION
Joints of steel pipes shall be screwed with threaded joints and
fittings for 65 mm and less diameters above or below ground
and by movable flanges or as directed by the Engineer for
diameters larger than 65 mm.
3.2.1 Threaded Joints: Tapered pipe threads for field-cut threads.
Join pipe fittings and valves as follows:
Steel Pipe and Fittings for Fire Protection
System
Section 15417
Page 5 of 6
Note the internal length of threads in fittings or valve ends, and
proximity of internal seat or wall, to determine how far pipe
should be threaded into joint. Align threads at point of
assembly.
Apply appropriate tape or thread compound to the external pipe
threads (except where dry seal threading is indicated elsewhere).
Assemble joint and wrench tight. Wrench on valve shall be on
the valve end into which the pipe is being threaded.
Damaged threads: Do not use pipe with corroded or damaged
threads. If a weld opens during cutting or threading operations,
that portion of pipe shall not be used.
3.2.2 Flanged Joints: Flanged joints shall be furnished with bolts, nuts,
gaskets and all necessary accessories. Bolts shall be of the best
quality of steel with hexagonal head, washers and hexagonal nuts.
Bolt lengths shall be so that, after erection, the bolt shall not
protrude through the nut more than one to three threads. Gaskets
shall be one piece, full face type of best quality cloth inserted sheet
rubber at least 3 mm thick. Align surfaces of flanges parallel.
Assemble joints by sequencing bolt tightening to make initial
contact of flanges and gaskets as flat and parallel as possible. Use
suitable lubricants on bolt threads. Tighten bolts gradually and
uniformly with a torque wrench.
Coordinate flange standards with that of valves, pumps and
equipment.
3.2.3 Welded Joints: Employ, qualified welders and submit welders
qualification certificate to the Engineer. Comply with the
requirements of the ASME Boiler and Pressure Vessel Code.
Submit welding procedures and the technical data and
specification for electrodes.
Prepare end of parts to be welded in compliance with the joint
design set up in the applicable welding-procedure specification.
Use proper machine tools for cutting. Throughly clean rust, scale,
paint, oil or grease from welding faces and adjoining surfaces for a
distance of 20 mm from edge of the welding groove or from the
toe of the fillet in the case of socket-welded or fillet-welded joints.
In addition, remove any contaminating or surface-coating material
that may reach the weld area as a result of weld heat.
Layout and assemble various component parts. Carefully space,
Steel Pipe and Fittings for Fire Protection
System
Section 15417
Page 6 of 6
align and tack-weld together the parts to be jointed so that final
welded assembly will conform to the required dimensions
within acceptable tolerances (¡Ó 3 mm maximum end-to-end
tolerance). Ensure that a sufficient number and suitable
proportions of tack welds are provided to hold the parts in place
during ordinary handling.
Apply sufficient number of weld passes to suit the material,
thickness and position of parts to be welded. Start welding at
the bottom and progress upward, except for thin-walled
material.
Employ high degree of manual skill for downward welding to
secure adequate fusion with side walls and to avoid entrapment
of slag. Clean with wire brush each layer of deposited weld
metal prior to the deposition of the following weld-metal layer.
Chip or ground out surface defects which would other wise
affect the soundness of the weld. Remove bumps and sharp
corners or grooves.

PART 3 EXECUTION
3.1 INSTALLATION, GENERAL
Installation of steel pipes and fittings shall comply with
requirements of the Division 15 Sections.
3.2 JOINTS CONSTRUCTION
Joints of steel pipes shall be screwed with threaded joints and
fittings for 65 mm and less diameters above or below ground
and by movable flanges or as directed by the Engineer for
diameters larger than 65 mm.
3.2.1 Threaded Joints: Tapered pipe threads for field-cut threads.
Join pipe fittings and valves as follows:
Steel Pipe and Fittings for Fire Protection
System
Section 15417
Page 5 of 6
Note the internal length of threads in fittings or valve ends, and
proximity of internal seat or wall, to determine how far pipe
should be threaded into joint. Align threads at point of
assembly.
Apply appropriate tape or thread compound to the external pipe
threads (except where dry seal threading is indicated elsewhere).
Assemble joint and wrench tight. Wrench on valve shall be on
the valve end into which the pipe is being threaded.
Damaged threads: Do not use pipe with corroded or damaged
threads. If a weld opens during cutting or threading operations,
that portion of pipe shall not be used.
3.2.2 Flanged Joints: Flanged joints shall be furnished with bolts, nuts,
gaskets and all necessary accessories. Bolts shall be of the best
quality of steel with hexagonal head, washers and hexagonal nuts.
Bolt lengths shall be so that, after erection, the bolt shall not
protrude through the nut more than one to three threads. Gaskets
shall be one piece, full face type of best quality cloth inserted sheet
rubber at least 3 mm thick. Align surfaces of flanges parallel.
Assemble joints by sequencing bolt tightening to make initial
contact of flanges and gaskets as flat and parallel as possible. Use
suitable lubricants on bolt threads. Tighten bolts gradually and
uniformly with a torque wrench.
Coordinate flange standards with that of valves, pumps and
equipment.
3.2.3 Welded Joints: Employ, qualified welders and submit welders
qualification certificate to the Engineer. Comply with the
requirements of the ASME Boiler and Pressure Vessel Code.
Submit welding procedures and the technical data and
specification for electrodes.
Prepare end of parts to be welded in compliance with the joint
design set up in the applicable welding-procedure specification.
Use proper machine tools for cutting. Throughly clean rust, scale,
paint, oil or grease from welding faces and adjoining surfaces for a
distance of 20 mm from edge of the welding groove or from the
toe of the fillet in the case of socket-welded or fillet-welded joints.
In addition, remove any contaminating or surface-coating material
that may reach the weld area as a result of weld heat.
Layout and assemble various component parts. Carefully space,
Steel Pipe and Fittings for Fire Protection
System
Section 15417
Page 6 of 6
align and tack-weld together the parts to be jointed so that final
welded assembly will conform to the required dimensions
within acceptable tolerances (¡Ó 3 mm maximum end-to-end
tolerance). Ensure that a sufficient number and suitable
proportions of tack welds are provided to hold the parts in place
during ordinary handling.
Apply sufficient number of weld passes to suit the material,
thickness and position of parts to be welded. Start welding at
the bottom and progress upward, except for thin-walled
material.
Employ high degree of manual skill for downward welding to
secure adequate fusion with side walls and to avoid entrapment
of slag. Clean with wire brush each layer of deposited weld
metal prior to the deposition of the following weld-metal layer.
Chip or ground out surface defects which would other wise
affect the soundness of the weld. Remove bumps and sharp
corners or grooves.
