Great Work Pipeline Hot Tap Installation and Best Teamwork to Hot Tapping and Plugging 🔔 Thanks for watching my videos, enjoy, and subscribe for more interesting videos! / @machinerytechnology
I don’t know much about pipeline, I’ve usually just done a variety of construction and mainly tank maintenance in refineries. Watching this kind of stuff does make me appreciate the hard work pipeliners do out there! Cool vid 👍
I'm a retired 1104 sec.9 welder after 33 years. This kinda looks familiar haha. Man I really miss jobs like this and the guys especially. Real characters. I'd like to thank the engineers and scientists that constantly trained us. Keeping us alive. Thanks for the video makes me feel good providing natural gas to our country. Only in America. Beautiful.
I see in the vid they are attaching sections to the main pipe to extend/ change the flow of liquid inside. As you are a welder and you may be able to answer this: the solid pipe they are making additions to do not seem to have a hole in them for liquids to flow through before the add the new piping ( two halves welded on underside and top) so how is a hole done do liquid can flow through the new addition?
Welding is about fusing metals and alloys that can be plus also defying gravity so the weld looks good but the hardest part is when you have to get in the most awkward positions especially when you are stick welding ( manual metal arc ) . Tig is also difficult and a skilled welding process but today many workshops cap the pipes with the Mig because it’s a lot faster but this is only semiskilled
I was a pipe welder for 35 yrs in the pipefitters union had every certification Stick, Tig, Mig in the book was also certified in Structure Steel brings back a lot of memories but got to tell u have seen a lot better looking welds than the ones in this video. I was lucky I was taught by a welder who was absolutely incredible every weld he did looked like it was done by a machine its a incredible skill once u master it.
I enjoyed doing this kind of work several times over in the last 15 years .I miss solving water supply problems .Steel work is good though it's being replaced by HDPE in some works .
The tapping sleeve & valve method has been around for more than 60 years. The fun is when you need to insert a valve in-line. In my years as a contractor we would freeze the main on each side with a huge amount of dry ice. Since I retired about 30 years ago there may be a better way nowadays ❓
Always like too many guys in slacks standing around, you know just just make sure the guys actually working are doing it right. " yea dear, today was rough out of the office. Had to go 45 miles out in the hot ass country to watch the welders and fitters. Just to make sure they were doing it right. It was a real pain in the ass day and I'm worn out."
Technically you can keep the line going but it adds a whole level of complexity and certainly become a big safety concern. This line was not in operation for the video. It had water in it or was added during the tap operations. If a tap is needed and well planned/executed, best to slow down and do it right without the hydrocarbons. I work in the offshore oil industry. Taking this kind of risk anymore just isn't in the cards anymore. We recently had a leaky gasket on our sales gas line discharge about 100' below the water line. 1 small bubble every minute or so. We stopped sending gas, burned what we could with our generators and flared the rest until the divers could come fix the problem about 6 weeks later. Thankfully safety is a major concern in the modern oil industry.

A normal "hot tap" can be performed with the line in operation. This is installation of a stopple. My employer usually stops for this process as it is to create a seal to perform work, so it will be stopped anyway for the work. @@jadams1722
Hello, our company produces various types of pipeline fittings such as steel lined PTFE, steel lined plastic (PP/PO/PE), steel lined rubber, lined tank bodies, sprayed PTFE, isostatic pressure PTFE, electrostatic PTFE, PTFE adhesive plates, etc. Our pipelines are used in chemical plants, sewage treatment plants, power plant desulfurization and denitrification, pharmaceutical plants, phosphate rock, silicon industry, lithium batteries, new energy, hydrogen energy, etc.
in the UK this is called Stove Pipe welding. I use to do it many years ago before my body could not take the cold wet day. I still weld but indoors 😇🥰 I did like it even thought it was ALWAYS rush rush rush. I've never worked on pipe already in the grown. Always putting use pipe lines in.
I’ve seen PG&E guys do a hot tap on a 6in gas main! I was like WTH man, I’m gonna go get breakfast, I’ll be back in an hour or two after y’all blow yourselves up! But it was no big deal, I guess they do it all the time.
My son is an engineer in FL and SENT me pics of the same process on a 24" WATER line, 240 PSI. He oversaw the procedure down in the hole. I really wish he would not do that.
Amazing, do the fancy rod holders heat the rod to prevent moisture? How is this a hot tap if they isolate both side with the tall equipment, I thought it was gas, then at the end, saw the water, or is it gas but they full water first. To get the gas to flow? Please tell me more...
So they don’t dig up all that concrete that was used as the base and recycle it do they because of the cost and it is out of sight. It has a big effect on how the rain penetrates back into the ground.
Excellent work. Outstanding. From a safety perspective, It’s a fail. The entire hole needed shoring. I am the general manager of on-site safety for my pipeline company, and here in America, all cuts in the ground that are deeper than 4 feet, “will have shoring.” Per OSHA.
الجماعة بتوع التركيبات الميكانيكية ممكن يجمعو القطع الخاصة دى بكل سهولة هههه محبس وبردة وشوية حاجات مش صعبة لكن الصعب هنا الارتداد داخل الخط فيجب على المهندس المنفد عمل قاعدة لحمل الوزن القطع وزيادة التثبيت قبل وبع الجزء المراد تثبيتة لسلامة الخط عند التوقف واعادة التشغيل
Not sure of the country where this is but they sure don't have the same regulations as the U.S. when it comes to trenching and excavations. OSHA would not be impressed.
Eu queria saber,o porquê jogaram aquela tinta spray, com aquele aparelho parecendo uma ferradura. Nos 1,35 _1,40 do vídeo. Agradeço a quem possa resposta! Grato abraços
No… Underground pipe is wrapped with a sticky insulation. Afterward it’s blast heated with a propane “weed burner” thus process hardens it! It will last forever.
