3
What is the task I am going to perform? What
document describes it? Do I understand it?
The task is to receive training on the use of the
sites hanger installation specifications.
The hanger installation specifications are
13-PN-204 (Nuclear Installations) and 13-PN-205
(Balance of plant). Today we will be looking at
13-PN-205 which is similar to 13-PN-204.
This presentation will provide an insight on how
to use the Hanger installation specifications
more effective.
4
What is the worst thing that can happen and how
can I prevent it?
The worst things that could happen is that I do
not pay attention and do not receive the material
presented.
5
What else could go wrong?
Not using the work mechs, procedures and
piping/hanger installation specifications
correctly will result in hanger installations
that do not meet design requirements. This can
lead to costly rework.
6
What safety and/or radiation protection
considerations?
The training setting today will not require the
use of PPE and does not have any radiation
protection considerations.
7
Is my training and are my qualifications
up-to-date?
The taking of this course with successful passing
of the CBT Test will help you to complete
prerequisites for future SWMS Work Assignment
Areas.

Course /Lesson Terminal Objective
Using 13-PN-205, participants will identify
requirements for the installation of pipe
supports, hangers and piping system struts.
Participants are required to score 80 on a
written exam.
13
Pipe Support Installation Specifications

• Pipe supports are designed to transmit loads from
  a pressure retaining barrier of the piping to a
  load carrying structure

14
Pipe Support Installation Specifications

• The design and location of pipe supports shall be
  the responsibility of Engineering
• All design details will be shown on drawings,
  including miscellaneous steel when required

15
Pipe Support Installation Specifications

• Installation of supports shall be in accordance
  with the design drawings, applicable codes and/or
  standards, as well as 13-PN-204 or 13-PN-205

16
Pipe Support Installation Specifications

• The pipe support location critical dimension is
  used to locate the support on the pipe system

17
Pipe Support Installation Specifications

• The pipe support location critical dimension
  shall be indicated on the location plan of the
  pipe support design drawing or on a sectional
  view of a vertical run of pipe and will be from
  an elbow, tee, flange, etc., to the support's
  location.

18
Pipe Support Installation Specifications

• If a dimension is not provided, the critical
  dimension shall be the reference dimensions from
  the building columns shown on the location plan
  of the pipe support design drawing, or for
  vertical run pipe, the centerline elevation of
  the component detail.

19
Pipe Support Installation Permitted Deviations

• Deviations are permitted provided that the
  function of the support is not affected, and the
  required clearance for thermal growth is
  maintained.

20
Pipe Support Installation Permitted Deviations

• Deviations and tolerances for sizes, lengths, and
  position of miscellaneous steel angles, channels,
  I beams, tube steel, wide flanges, and plates
  shall be in accordance with 13-PN-204 or
  13-PN-205.

21
Pipe Support Installation Permitted Deviations

• Though the specifications allow for deviations,
  for consistency on these deviations a team leader
  or the planner shall be contacted for the proper
  interpretation/application of the specifications.

22
Runs of Pipe ? 2-1/2Free of Obstructions

• Support location (as shown by the support's
  critical dimension) may deviate
• 2 inches transversally
• 12 inches axially

23
Runs of Pipe ? 2-1/2Free of Obstructions

• Miscellaneous steel members with field welded end
  connections may be repositioned up to
• 2 inches vertically
• 2 inches horizontally

24
Runs of Pipe ? 2Free of Obstructions

• Support location (as shown by the support's
  critical dimension) may deviate
• 4 inches transversally
• 9 inches axially
• (except when the support location is within 12"
  of valves, flanges, or any other concentrated
  load)

25
Runs of Pipe ? 2Free of Obstructions

• Miscellaneous steel members with field welded end
  connections may be repositioned up to
• 4 inches vertically
• 4 inches horizontally

26
Sway Struts

• Shall be installed such that they are within
  five degrees (5?) of the design angle when the
  pipe is at its design operating temperature and
  pressure

27
Spring Hangers

• May deviate a maximum of five percent (5) from
  the design cold load setting

28
Variable Spring Or Constant Spring Supports

• May deviate from the vertical 4? between the
  beam attachment load bolt/pin and the load stud
  of the pipe clamp when the pipe is at its design
  operating temperature and pressure

29
Pipe Strap and Restraint Clearances

• Clearance between pipe wall (or pipe attachment)
  and structures shall be as follows

30
Pipe Strap and Restraint Clearances

• Where 1/16" clearance is specified at one side
  and no clearance is specified at the opposite
  side in the restrained direction, the 1/16"
  clearance may be inspected from 0" (free to
  slide) to 1/8" maximum clearance.

31
Where 1/16" clearance is specified at one side
and no clearance is specified at the opposite
side in the restrained direction,
the 1/16" clearance may be inspected from 0"
(free to slide) to 1/8" maximum clearance.
32
Pipe Strap and Restraint Clearances

• Where 1/16" clearance is specified at each
  opposite side, the inspection may be from 0"
  (free to slide) on one side to 1/16" minimum and
  1/8" maximum total for both sides.

33

• Where 1/16" clearance is specified at each
  opposite side,

the inspection may be from 0" (free to slide) on
one side to 1/16" minimum and 1/8" maximum total
for both sides.
34
Pipe Strap and Restraint Clearances

• For all other cases, the minimum inspection
  clearance shall not be less than the design pipe
  move-ment in the direction of the minimum
  clearance plus additional clearance for thermal
  radial growth.

35
U-Bolt Clearances

• U-bolt clearances for guides may be from 0" (free
  to slide) to 1/8" maximum

36
U-Bolt Clearances

• Clearances for 1" dia. plastic coated U-bolt may
  be from 0" (free to slide) to 1/4 maximum.

37
Pipe Strap, Restraint and U-Bolt Clearance
Inspection and Verification

• Inspection and verification of 0 (free to slide)
  clearance between pipe wall and miscellaneous
  steel supports, restraint straps, welded pipe
  attachments, or U-bolts, the inspection method
  may be one of the following
