: Natural Gas piping fittings
: Usaiman June 01, 2010, 04:09:24 AM
Hi guys, I'm stil new to this forum...
Just want to ask whether any body here had deal with natural gas piping before. The piping is to supply natural gas to burner for Hot oil Furnace.
For maintenance, we need to remove last spool to the burner regularly for servicing and cleaning. The fittings been used since equipment installed on the last spool is UNION and lately several times we found leaks almost 16 locations out of 48.
Is UNION reliable to be used for this type of service? If not  then any other  suitable way to be used?

Thanks in advance folks.
