pipe project

some traps. putting the saddle pads and branchs on.its all 8010.got some shots of my helper buffing it ha ha. photogenic guy. he really is a hard worker. Attached Images

Reply:specopswelderWhat size 8010, and how many passes?Opus
Reply:where do those saddle pads come from? im used to seeing weldolets(bonneyforge comes to mind as a manufacturer) but those look different..
Reply:Opus it was welded with 3/16 8010 with an occasional 5/32 depending on what was needed most of thas pads have 5 passes on.375 wall pipe and the.500 has 6.the saddle pads are different than bonney forges they are furmanite they also make good hot taps and full encirclement sleeves and suchfew more pics some 2 inch schd 80 and completed project heading to hydro testI will admit i had to use 5/32 for the 2 inch. 3/16 is  out of my skill level. The guys who can do it make it look easy.I don't have a picture of the last two saddle pads welded. Attached Images

Reply:Buffing is just wire wheeling it. Its kinda a joke between me and the helper. he calls it buffing and I call it brushing. He thinks his brushing is better than most to the point of buffing.ha ha so the term stuck with me.
Reply:am i seeing 2200 psi?
Reply:2200psi would generally be hydrostatic test pressure for most 600lb flanged pipe fabrication, maop is like 1440.
Reply:Rifleco your exactly correct. On the test pressure and maop. We do take some projects to 5000 psi but it is a very special application that those are used for.
Reply:Looks like you have one hell of a shop there. Id love to get to work with more pipe but nothing but structural these days.
Reply:Nice work, looks like you have plenty of room to build things there.TOO MANY TOOLS & NO MORE SPACE
Reply:thats impressive.  sticking 2 pieces of metal together is one thing, 2200 psi isi another.  nice work.
Reply:specopswelderWhat is the Orange Door looking device on the end of the pipe?Opus
Reply:The orange door is a door to place a pigInto or out of for pigging pipe. It's just a hinged cap rated for pressure.
Reply:scecopswelderI've always wondered how the 'pig' got into the pipe.Is the 'pig hatch' permanent or temporary; it doesn'tlook like it could withstand the pressure test?If temporary, how much pressure does it take to pusha pig?OpusLast edited by OPUS FERRO; 05-27-2013 at 09:41 PM.Reason: punc.
Reply:pipeline operators run pigs every so often to clean lines, or get liquids out or find anomalies in a pipeline. The pressures differ on each pipeline and diameter of line also the type of pig. 100psi is more than enough to push a pig but some run at up to 1500psi or more depends on the purpose of the line. There is typically a launcher where they put pigs in and a receiver where they take the pigs out on the other end of the line so they are permanent.  they all vary from crude oil systems to gas systems but that is the general purpose
Reply:Opus the "pig hatch" is permanent it is about an inch and a half thick machined to fit A tapper on the inside of the door. It is a press fit that has two locking bands around the outer circumference that when locked have a 1 inch bolt holding them shut. It held the 2220 psi for 8 hours. its all in the internal taper and locking system. On the next one i will get some pictures of it close up for you.The pigs are put in and out of these doors.Launchers and receivers. for a pipeline to be pigable it has to have bars on T's off the main header after they are 40% of the header diameter.These keep the pigs from turning down branches.as for pressure it depends if it is a smart pig or not. there are several different types. I am not real familiar with the pressure required to push one. I am just a dumb welder... paid from the shoulder to the holder.. I will ask some of the guys that do the pigging and see what they say.Last edited by specopswelder; 05-27-2013 at 10:57 PM.
