The manufacture of pipes and tubes

Steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld. The first methods for producing steel pipe were introduced in the early 1800s, and they have steadily evolved into the modern processes we use today. Each year, millions of tons of steel pipe are produced. Its versatility makes it the most often used product produced by the steel industry.

Steel pipes are found in a variety of places. Since they are strong, they are used underground for transporting water and gas throughout cities and towns. They are also employed in construction to protect electrical wires. While steel pipes are strong, they can also be lightweight. This makes them perfect for use in bicycle frame manufacture. Other places they find utility is in automobiles, refrigeration units, heating and plumbing systems, flagpoles, street lamps, and medicine to name a few.

What I have written here is for people who want to know how it all began. If you are professional, I suggest other blogs so that, ,, and other blogs that you find online.


People have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists who diverted water from streams and rivers into their fields. Archeological evidence suggests that the Chinese used reed pipe for transporting water to desired locations as early as 2000 B.C. Clay tubes that were used by other ancient civilizations have been discovered. During the first century A.D. , the first lead pipes were constructed in Europe. In tropical countries, bamboo tubes were used to transport water. Colonial Americans used wood for a similar purpose. In 1652, the first waterworks was made in Boston using hollow logs.

Development of the modern day welded steel pipe can be traced back to the early 1800s. In 1815, William Murdock invented a coal burning lamp system. To fit the entire city of London with these lights, Murdock joined together the barrels from discarded muskets. He used this continuous pipeline to transport the coal gas. When his lighting system proved successful a greater demand was created for long metal tubes. To produce enough tubes to meet this demand, a variety of inventors set to work on developing new pipe making processes.

An early notable method for producing metal tubes quickly and inexpensively was patented by James Russell in 1824. In his method, tubes were created by joining together opposite edges of a flat iron strip. The metal was first heated until it was malleable. Using a drop hammer, the edges folded together and welded. The pipe was finished by passing it through a groove and rolling mill.

Among engineers and industrial pipe fittings

I study construction engineering at the University and I will soon graduate. It’s quite scary but I am also glad to have found an internship in a construction company that mainly work out in the field with mining and tunneling. My education is primarily aimed at working as a project manager in various construction projects but I think it’s good to start your career on the bottom to see how the workers really do their job, how it’s all planned and how things work logistically, and then slowly work your way through to the top.

Start working in the field to get a better understanding of what is needed from me to do a good job and plan well before the projects. I will do my internship practice at a fairly large company that primarily works with tunnels and if I understand correctly, I will begin by lay pipes along the tunnel. They work with a company that manufactures pipes and industrial pipe fittings and I have been instructed to maintain contact with them. It in other words my responsability that everyting goes as planned, that everything fits and is ordered correctly.

It’s scary to have all this responsability, but also engcouraging. I will mainly be responsible for all pipes and pipe fittings. I have studied for quita a while and I’m sure I will do a good job. But I’d be lying if I said that I wasn’t nervous. There are so many different components that has to be synchronized and double-checked. Luckily I have a good tutor who guides me through this great world of pipes. Wish me luck!

About the most beautiful tunnels…

About the most beautiful tunnels…

Digging cool and great tunnels is a very hot, dangerous and filthy job.

Since the old, or should I say ancient Greeks,  the diggers and builders of great tunnels been using all kind of tools specially designed to carve out hard rocks and mountains in order to get the perfect way for building the tunnel.


Now its all up to you my friend, pick your favorite location and chose you tunnel-digging-technique, and see how long it takes you to dig a mile-long tunnel! Don’t you forget to excavate the ground with a reliable tool and to support any unstable ground around you while you dig!

Diggers often face unexpected challenges so take it easy and enter the cave at own risk.
