We are currently installing a steam pipeline from A to B heating network to import about 200Mlbs/hr of steam. We expect to finish the 7000’ of underground 18” pipe installation in the coming months. Before we place the line in service, we will need to remove any foreign matter in the pipe and we are trying to determine the simplest, but effective, way to do it. Steam blow is one option that is very effective, but is costly and requires much planning, and not so easy in a downtown setting. I am sending this inquiry to find out if any of you have added any significant length of piping to your network (or to customers) in the past and what method was used for internal cleaning before placing the line in service. It would be great if each of you would provide your responses with the following information.
Length of pipe added (year & linear feet)-
ID (inches) of pipe-
Cleaning method used-
Steam blow used- If yes, provide info on how it was performed. (e.g.- pressure, flow, silencer used, procedure,.. etc.)
