Basics of Pipe-fitting and Welding | How to Fabricate a Spool

what is going on my work to family this is Victor here I'm here in the world to chat again with another video but this time it would something more different all right guys have you ever asked yourself what are you gonna find out in the field or what's the process of feeding a pipe out in the refinery guys this time I'm here with my good friend Marvin all right it's a really good Texas fight Vader is gonna show us how to how to fit this is cool and I'm gonna weld it all right we'll go from there let's do it Marvin Chavez Texas pipefitter ten years experience today I'm fabricated spoil piece I'm gonna get Victor my boy well this piece for us so let's make this fit we got here today so it's a major drawing we're gonna fit redline we're gonna make this full spool piece we're gonna start out with a 6-inch pipe see you're number one right here you look like a b-lynch you're building material go to number one six inch you always got a bear fight what kind of material it is so this will be a sketch skander standard wall a 106 which is carving we're gonna go here number six will be your elbow 96 inch standard wall so we're gonna go that's going to be a reducer concentric six two four number three go here your bill material reduce your concentric standard wall and then their number two is somebody else totally rebuild material number two 4-inch schedule standard wall a 106 which is carbon steel and also you got got a elbow right here floor number seven it's gonna be a four-inch 90 long radius standard wall fitting and then we also got our flange right here it's gonna be f10 well you have 10 building material 4 inch flange 150 razor-faced scheduled standard today what I'm going to show you is how to find your take out from 90 to 90 or take out basically when you have two fittings you got to take out those two fittings to get the measurement of the pipe to figure that out you have a blue book which page 95 and 96 and we know your fittings are long radius 90s you go to your 6 inch on the side screw over to the side I'll tell you here it'll show you step by step on a long radius 6 inch your take out will be a 9 inch take out or easier way to do that if you don't have one of these you go ahead and 6 inch 1/2 a 6 inch will be three you had these two numbers up give you nine I saw you get your take off for a 90 long radius if you run into a short radius 90s which hardly see them out in the field but if you do run into them shortly is 90 is the same size of the pipe it's good to know another important a very important thing you want to look at and look at these isometric drawings it's gonna be relevation always double-check your elevations like right here L stands for elevation you got 93 foot seven and a quarter you're gonna have elevation change of 4 foot to 3/16 certain change to elevation 97 flow at 9 and 7/16 so it's always good to double check that we are in the field you know you're gonna have an elevation change another very important key beyond refinery on the plant anywhere you're at always ask where's planned north usually they'll let you know here's plan north as you can see when you have some metric drawing the north is right here so the pipe that we're fabián up today is running east and west our flange is running to the west very important when you're making a fit so we go ahead and fabricate this whole spool today we're gonna show you how to do it are you what you'll see in the field [Music] okay so we got a 6-inch pipe right here standard wall always got to make sure you make fit your pipes level we've got a two-foot level right here double check make sure this pipes level you see needs to come up just a little bit on this side good all right we got her fitting right here I'm gonna go ahead and make our fit onto the pipe I'll show you how to do that grab our fit especially on need 90s want to go ahead and grab a jack stands very helpful I'm gonna go ahead put the pipe together always got to make sure your two pipes on the beveled line up I'm gonna go ahead and go up on the jack stand once you got it nice that was lined up looks pretty good ask the welder kind of gap you likes I'm asked my boy back there hey Baek they're kind of gap you like like a 5/32 two or three sixteen Lumia 532 brim on 532 yeah all right sounds good man we'll go ahead and put a spacer we gotta go you got our 532 spacer go ahead put it between the pipe we got our gaap check your high low your high low it's gonna be the in the edge of the pipe on the bevel make sure it's good on a both top in sides you want to look on the inside if you like it all right we got the fit fit up 532 get you like it oh yeah all right go ahead and give me a tack on top all right good go ahead and check the square on the 90 to the pipe the way we do that after we get the first tack go ahead and take the pipe up just a little bit pull the spacer out go ahead and grab two squares take the square of the pipe to the fitting the way to do that always got to make sure your stove is clean [Music] as you can see there's no snow gap between the two squares if you have something like this it means you gotta pick up the pipe on the back end or if you had something like that that means our pipes not square but as you can see it's flush but when you get the weld or attack the bottom is you know the pipe square I bake then go ahead and give me a tap on the bottom all right guys I'm gonna use er 70s cheeks when I grow up and I'm gonna run uh 105 all right you always want to double check your high low after each tag it tends to move the pipe when you start putting heat tends to pull to one side so I always double check your high low the gap still good-looking the inside you can go ahead and tack the sides so on the 90s a little more difficult if you can you have it on the pipe like this go ahead and roll it to the side make sure your pipes level again if you see it's not level got to go up all right we've got a Nevel come back to the 90 way to check this go ahead and put a level on it and fitting as you can see is rolled and go ahead and pick it up another way to check it check the front side you can see it's off the level double-check your pipe pipe is still level Gaston those good high low still look good double-check it I baked them ready for attack well then give me one on top I'm pretty tax it last time double-check and make sure everything's good Neville you're 90 still level available all right back there give me a last tack on the bottom after he gives up the four tech the welder basically buying it off it's his response to be to keep it square so he's gonna have to quarter it so we leave it in the hands Victor okay we're gonna go ahead and make our reducer always got double check make sure everything's still level your pipe level a roll on your 90 still level here we go here we got our concentric reducing six to four go ahead and fit it up Victor to weld it out for us you know 532 gap check our high-low so it's good look inside of pipe make sure your size are good your top and bottom all right neither tack on top once victor will dare that out a pipe tends to draw will get that tag make sure everything's still level still good right here you can see on the level needs to come down just a bit usually what I usually do I'll get the welder there's will to protect the bottom and use the majority of times they will pull and you will see it right now they forgive me attack on the bottom double-check it well went down a little bit make a see it's level now we can go ahead and get the square from this face to this pipe and way to do that he's good to get someone to help you out on this part how come no you Victor hold the square right here ran from the beginning of the pipe and what we have right here it's 11 inches and five sixteenths and we got 11 inches and a quarter so needs to pull the 16 towards Victor so we'll go ahead and do usually on a 16th like I said I want to go ahead attack on his backside it's gonna draw its 1/8 sick with this when there's one thin the 16th or 1/8 easy just get the welder to protect the backside and with the heat will draw and it will come out square give me a tack on the side Victor okay go ahead and double check it make sure to pull check one more time 11 a 5/16 you're having a 5/16 oh yeah go ahead and get Victor get the last tack on this side it's square devil and that's how you fit a 90 in a rooster squared up to the pipe a key factor always remember always double-check your inside diameter inside diameters the inside your pipe so especially on fittings to pipe especially on the fittings they always come a little bit closer my me and my clothes usually got as you can see I have already grinded it will show you another video how to transition the pipe but I have already transition the pipe though with the fitting to work to the pipe as you can see usually how I do it is I usually burn about an inch close to the edge of your bevel as you can see right there about close five inches come to your pipe check it also it's about five inches it's always good thing double check best showing your fittings you never know especially when you real push on the welder if you're high-low is not matching up and house they have a hard time trying to weld it out especially when each every place you go to has a different tolerance within 1/16 or 8 want to make sure you make their job easier also yours as well I same steps we're gonna go ahead and fit this four inch pipe so it's fitting same constant double-check though it's thicker the pipe still level get your gap get my welder over here watch it bake there all right one foot one 1:41 I don't know money gonna give me a tack on this side Victor [Music] [Music] got a 4-inch 90 long radius I make this fit we got our gaap 532 high-low looks pretty good and also on this part gonna make sure your 90s roll with the pipe and your fittings if not you're gonna be out of square and this is very tedious sometimes especially one 90s trying to get the roll right all right it's good right there how about you Victor gonna give me a tack on top that was still good pipe for the level is still good go ahead and give me a talk on the bottom Victor and the very last thing get the square of the pipe to the fitting take the square right here as you can see see that back gap and so big three give me our tech on his front side or go ahead and hit it with the hammer just give it a little tap see these a little bit more give another tap do the magic trick damn give me a tax on this side Victor all right we got a 4-inch 115 razor-faced the reason why they call the razor face if you can see this right here here's the razor-faced flange and if it was a full face you wouldn't have this small lip right here usually will just be all one full piece but it's right here this is your razor face flange and usually you can tell by your ratings on the side for the flange four inch 115 WN or if the last two are F stands for razor-faced baby richter make this last weld and it's very important on this on the last part just don't put it together and make the fail on this part you're gonna have to use two whole pins make sure this flange is squared and level with this pipe and we have right here is two whole pins we're gonna go ahead and put them on the hole always make sure check got to hold the top usually I usually skip one so just skip wanna be right here okay always double-check reason why they call these two whole pins are they going to holes make sure we got them to four didn't want to have one right here because then you're gonna want hold it and everything's gonna be wrong I have to cut it back out three fix it again Oh make sure to four go ahead this make this fit last double check make sure your pipes level that will get your gap Oh check your high-low it's good and then also gonna get the roll of this flange beveled out it's kind of hard to see it's good right there once you got a level got the roll right on two holes your gap is good your high-low looks good get attack on top wait to give me a tack on top and you can see there's no there's no edges it's all flat all the way through your plans not lean to one side or five - up and down that's a good that's a good fit right there all right Victor that was good going give me a tack on the bottom I think I messed them up with that jack stand away so your specialty welder to get that done we'll go ahead and check the square for the flange and it's very important on these flanges due to the fact that usually these flanges weld up to another piece of pipe for space or both will want to say a motor or any flanges or any plant that is very important these stays square level because they're now they're gonna have a hard time trying to bolt it up get this square I've got me out Victor I got 7 and 1/16 and we got 7 so just needs to pull towards me a little bit so give me a tack on this farm there you have it guys we want to go ahead and fabricate a speeds due to the isometric car as we head over there we're all finished up and I will get my boy Victor go ahead and well this for his concentric reducer I hope this video helped out out got can for his like comment subscribe I'll go ahead and follow me on Instagram I'll get my boy - Victor well this out come on Victor well this out in three days [Music] [Applause] [Music] [Music] [Music] [Music] [Music]
