5. Design Limitations
5.1 Design Criteria
5.1.1 Design Parameters. Supports have been designed to provide adequate support at maximum support spacing specified in SES P01-E09. Service temperature, pipe wall thickness and hydrostatic loads have been considered in the design.
5.1.2 Selection Tables. Selection tables and load limits have been provided to enable correct support application. All supports are identified with a unique symbol or code identifying type and material of construction.
5.2 Materials
Materials of construction of the pipe supports shall be specified in the individual pipe support standard drawings.
5.3 Welding and Postweld Heat Treatment
All welding, other than attachment to pressure piping, shall conform to AWS D1.1. All welding and Postweld heat treatment to pressure piping shall be in accordance with SES W12-F02.
5.4 Service Limitations
The standard supports shall not be used in the following situations:
a. Vacuum service
b. Cold insulated piping
c. Acoustically insulated piping
5.5 Design Limitations
Stress analysis shall be required when any of the following conditions exist:
a. Temperature of minus 29 °C and below
b. Pipe operating pressure above 20.7 kPa
c. Piping is to or from reciprocating compressors or pumps
d. Lines in hydrogen service
e. Lines in oxygen service
f. Lines in category M service
g. If columbium stabilized steels (type 347 ss) thicker than standard weight, or exceeding 6 mm thickness are used.
6. Fabrication
6.1 Pipe Support Locations
The type and location of the required pipe supports shall be shown on the piping drawings, or piping isometric drawings.
6.2 Responsibility
The responsibility for furnishing and installing pipe supports shall be as follows.
6.2.1 Pipe Spool Fabricator. The pipe spool fabricator shall be responsible for fabrication and attachment of all weld-on supports, and pads on shop fabricated piping.
6.2.2 Field. The construction contractor shall supply and install all supports, pads, field fabricated piping and random pipe. Construction contractor shall also supply and install bolt-on supports, field supports, and the auxiliary steel shown on the standard drawings.
6.3 Dimensions
The standard support drawings shall provide the dimensions for the supports for various pipe sizes.
6.4 Structural Shapes
The standard support drawings shall show dimensions and weights of a fabricated part, with dimensions in SI units.
6.5 Protective Coatings
All carbon and low alloy steel supports shall be hot dip galvanized except for field weld surfaces. Field welds and adjacent surfaces shall be painted after welding, in accordance with the procedure for repair of galvanized surfaces specified in ASTM A 53. Coatings for stainless steel shall be in accordance with SES Q01-G02.
6.6 Marking
Each support shall have its identifying code marked on a web or other nonbearing surface. Marking of austenitic stainless steel shall be done using paint or ink which contains no harmful chemicals, for example zinc, copper or any other ingredient which may cause corrosive attack on the base metal upon heating.
6.7 Shipping
6.7.1 All compressor line clamps shall be shipped completely assembled.
6.7.2 Bases for supports that require field adjustment shall be tack welded to the support.
6.7.3 Supports that require slide plates shall have the slide plates suitably protected and securely
attached to the support.
7. Erection
7.1 Compressor Line Clamps
The clamp shall first be torqued finger tight, and then the number of additional turns shall be as shown in SES P19-G07. The torque shall be applied to the nut on top of structural shape or plate ‘A’ only, while the two lock nuts are backed off. After torquing, structural shape or plate ‘A’ shall be parallel to the top of support. Finally the two lock nuts shall be fully tightened.
7.2 Adjustments
If chatter occurs during service testing at operating temperature, additional torque shall be applied to stop chatter. The clamp shall not be tightened to the extent that restraint occurs in any direction other than intended by the clamp design.
