Pig usage isn't always the case for specing full bore valves. There are times in polymer applications where full bore valves allows the use of smaller pumps (less cost) due to their decreased pressure drop as opposed to reduced port valves which increase pressure drop requiring larger pumps...
There are any number of types of fittings that could be used in this application. It is also dependant on location of manufacture. To be sure what type of fittings were used, why not contact Siemens and have the equipment model no. and serial no. at hand. Also, the fittings themselves may very...
Check into the Armstrong International site. They have software on line or did at one time for calculating the number and size of tracers required and insulation requirements. There is also softwre for doing the economics analysis.
One question is this a currently working drawing, i.e. the contractor is currently working with the drawing or is it an archival set that was supplied on completion of the project. If the former, the contractor needs to be notified immediatly. If the latter, the revision needs to be circled

Anyone thought about the toxic & hazardous releases to the environment via air vents in HC lines? Water doesn't have this problem. Besides, there is a major campaign on by the Government and Industry to eliminate or minimize any and all hazardous fugitive emissions or releases. And that is tied...
What happens to condensate & water when it is dropped from a higher pressure zone into a lower pressure zone? It flashes to steam and there is a significant volume expansion which drives the remaining water/condensate at much higher velocities (sometimes sonic)causing the hammer you're...
As for slope it depends on the situation. the general rule of thumb of 1:100 is the nominal. then there is the max/min conditions dictated by the field. The only hard and fast rule is, do not pocket condensate lines.
Safely handling of Conflagrations and Deflagrations is an art unto self. Depending on the materials involved, one can experience instataneous pressure rises and or temp. rises. Which can and will result in catastrophic failure and injury and death.
This is not something you want to research...
They're called "jack screw" or "jack bolts". Nothing exotic here, they're just a hex-hd capscrew placed between the bolt holes of the Flg. at 180 deg. apart. See the detail of an orifice flg.. Some owners spec's require them at every blind location.
skuntz,
"Equalized flow splitting"-setting up pipe layouts so that flow is equalized in each branch. For example, three branch, one header three seperate branchs that are identical so that pressure drop is the same. Four or more branches, Main hdr, two branches, then two more branches on each...
If you're running water and sewer, depth is dependant on geographic location and the depth of the frost line and any existing lines that you may cross (depth of existing lines also applies to HC lines).
The general piping design rule of thumb is, up to three branches, equalized flow splitting is not required. Four and above, equalized flow splitting is required.
