Loading Data

Self-load, thermal load and seismic load of piping system shall be considered as loading data. Special instruction for loading data is described below:

(1) Nozzle of vessel Heat Exchanger and Tower

Nozzle reaction forces shall be informed by using the form sheet . If allowable load is prescribed, nozzle reaction forces exceeding the limit shall be informed.

(2) Lug Plates for Vessels, Heat Exchangers, Towers and Tanks.

Any vertical load greater than 500 kg shall be indicated.
When the thrust force is greater than 500 kg. the thrust force and its direction shall be indicated.
Strength of support member shall be checked for large vertical load or thrust force.

(3) .Platform of Equipment.

Any concentrated load which is greater than 375 kg shall be indicated on the information drawings.

(4) Pump

Nozzle load which exceeds the allowable load specified in "Standard Practice for Piping Flexibility Analysis'" shall be informed by using the form sheet

(5) Tank Nozzle

Loading data for tank nozzles (6" and larger in size) shall be informed by using the form sheet

(6) Pipe Rack

a. As a rule, self load of each line on beams shall be informed as uniform load (kg/m). however, if self loading data of the line shall be informed as concentrated load individually.
b. For anchor points and guides on the main beam, if the thrust force is greater than 350 kg, loading data with direction shall be indicated at each loading point.
c. When the load of piping system work away from the center of beam or column, the moment arm shall also be clearly indicated as well as the load data.

(7) Structure (Including furnace structure)
a. Piping load works on beam shall be informed as concentrated load.
b. When the load of piping system work away from the center of beam or column, the same consideration shall be given as specified per. 3.6 (c ).
c. For insert plate, if the load is greater than 1000kg, loading data shall be shown on information drawing with size and location of the insert plate.
d. For structure floor, if the load at support point exceeds the following value, the loading data shall be indicted on information drawing.
- RC floor Vertical load thrust force 1000 kg
Thrust force 500 kg
- Steel floor Vertical load thrust force 500 kg
Thrust force 500 kg
Piping load greater man above should directly be loaded on beams not steel floor plate, and if necessary, sub-beams for loaded on beams not steel floor plate, and if necessary, Sub-beams for load transmitting shall be arranged.
e. If the vertical load of a line due to thermal expansion or contraction of piping system is greater than 500 kg. the loading data of the line shall be informed as concentrated force combined with self load.

(8) Stanchion

a. All loads working on stanchion shall be informed.
b. Piping support shall be designed so that no thrust force works on stanchions, unless
stanchion is so designed to sustain the thrust force.
c. If necessary, instruction must be given to Architectural Group so that friction force due to thermal movement of piping system will be evaluated by them.

(9) Pipe Sleeper

a. Self load of piping shall be informed as uniform load (kg/m). however, if the load of a
line is greater than 1000 kg at support point, the load data of the line shall be informed as concentrated force separately from other lines.
b. All thrust force and their direction shall be informed.
c. If necessary, instruction must be given to Architectural Group so that friction force due to thermal movement of piping system will be evaluated by them.

(10) Pipe Support Foundation

a. In paved area, if the thrust force greater than 300 kg works on pipe support or the vertical load is greater than 1500 kg, the base plate type and loading data shall be informed.
For pipe support foundation, moment due to thrust force of piping shall also be informed. If necessary, instruction must be given to Architectural Groups so that friction force due to thermal movement of piping system will be evaluated by them.
b. In unpaved area, the loading data shall be informed to all support foundations. However, if the vertical load for pipe support is less than 300 kg; the vertical load may not be necessary to inform.
c. Type of base plates of pipe support foundations shall be informed to Civil Design Group. Dimensions of pipe support foundation shall be designed by Civil Design Group.
d. The numbering system for stanchions, support foundations and operating stages shall be as per project-wise.
