Hello to all; We have a GRP underground pipeline for sea water transportation. Because of clash with another pipeline, a portion of pipe moves up and after a couple of meters moves down in the previous elevation, and therefore makes an air pocket in the line. Naturally we need a vent hole on the...

As you see in the picture, we have a GRP pressurized fire water header line with a couple of branches that diverge from it to distribute water to different users. In our project the designer has used separate pipe for each line of mentioned users. I think we can diverge one branch from the...

As you see in the picture, in the fire water underground piping network, we have a header line with many branches diverge from the header separately. For branches with final destinations near each other such as branches No. 1, 2 and 3 can we combine them into one branch and diverge it at the end...

IN PIPING HYDROSTATIC TEST, RECOGNIZING LEAKAGES IS BASED ON PRESSURE DROP AFTER HOLDING TIME, BUT IN CASES, PRESSURE GAUGE SHOWS PRESSURE DROP BECAUSE OF DECREASING WATER TEMPERATURE DUE TO AMBIENT TEMP IN HOLDING TIME; AND WE CAN’T UNDERSATAND ABOUT LEACKAGE CERTAINLY. NOW I NEED A FORMULA...

Hi; We have a problem about material recognition in piping job. some of our pipes don't have color code and we know no way for confirmation of materials used in them, especially for nace materials. How can you realize that the material is correct?

Hi; In piping support design specs & codes we see tables of pipe spans, as distance between two weight supports in a straight horizontal line cannot exceed this amount. Now the question is if the line is not straight and there is a change in the direction of line (for instance by elbows), what...

Hi; How we can find allowable distance between two crossing or beside pipelines.
