Manufacturing method of seamless pipe-ERW Steel Pipe
Hot-rolled seamless pipes are generally produced on automatic pipe rolling units. After checking and removing surface defects, the solid tube blank is cut into the required length, centered on the perforated end face of the tube blank, then sent to the heating furnace for heating, and pierced on the piercing machine. Spin and advance the solid blank inside the process of piercing holes under the influence with the roller as well as the end. Then the solid blank is hollow finally, which is called gross pipe. Send to the automatic pipe rolling machine to continue rolling. Finally, the wall thickness is adjusted by the equalizing machine, and the size is sized by the sizing machine to meet the specification requirements. It is a more advanced method to produce hot-rolled seamless steel pipes by using continuous rolling mills.En savoir plus -
Stainless Steel Pipe and Tube Manufacturing Process-ERW Steel Pipe
In the nineteenth century, rolling mill technology was the only technique used to manufacture stainless tubes and pipes for industrial purpose. This rolling technique involved long procedures. The rolled strips of sheet were formed into a circular cross section with the help of funnel rolls. The lap welding was then done on these rolled strips through the forge welding process.Thankfully with the advent of development and technology, various processes came into existence for the manufacturing of stainless tubes and pipes in India. Now-a-days, stainless steel pipes and tubes are manufactured with continuous tube mill using multitorch tungsten Inert gas. The filler metal or forge welding process is not used in this technique.En savoir plus -
The First Methods for Producing Steel Pipe -Welded Steel Pipe
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.En savoir plus -
What are the production processes for LSAW steel pipes?-ERW Steel Pipe
The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or lap welded in the same heat (forge welding process).Toward the end of the century, various processes became available for the manufacture of seamless tube and pipe, with production volumes rapidly increasing over a relatively short period. In spite of the application of other welding processes, the ongoing development and further improvement of the seamless techniques led to welded tube being almost completely pushed out of the market, with the result that seamless tube and pipe dominated until the Second World War.During the subsequent period, the results of research into welding technology led to an upturn in the fortunes of the welded tube, with burgeoning development work ensuing and wide propagation of numerous tube welding processes. Currently, around two thirds of steel tube production in the world are accounted for by welding processes. Of this figure, however, about one quarter takes the form of so-called large-diameter line pipe in size ranges outside those which are economically viable in seamless tube and pipe manufacturing.En savoir plus -
The Types Of Steel Pipes-Stainless steel pipe
A steel pipe is steel with a hollow section and its length is much greater than its diameter or circumference. There are many steel grades and specifications of steel pipe products, and their performance requirements are also various. All these should be differentiated according to user requirements or changes in working conditions. Generally, steel pipe products are classified according to cross-sectional shape, production method, pipe material, connection method, plating characteristics, and use.En savoir plus -
A Brief History of Steel Pipe-
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. People have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists that 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. (Francis, 2009)Development of the modern day welded steel pipe can be traced back to the early 1800s.En savoir plus -
The Production Process of High Quality Stainless Steel Tube- Welded Steel Pipe
Floating/Drawing process of pulling a metal bar, rod, or wire through the whole of a die to alter its finish, shape, size, and/or mechanical properties. The tube drawing technique reduces the outer diameter, inner diameter, and wall thickness of the tube. The integrity of the surface of the tube is maintained, ideal for stainless steel tubes.En savoir plus -
Cintrage de tubes et tuyaux en acier et en acier inoxydable-Tuyau en acier inoxydable
The commonest manufacturing process used for steel and stainless steel tubes uses coils. Coils are rolls of steel cut from a slab that has been manufactured from cast steel. During the first phase of steel tube production, the coils are cut lengthways to form wide skelps matching the diameter of the steel tube that needs to be manufactured.These skelps then pass through a series of rolls. The final step is to weld the tube together along its long edge.This process can be used to manufacture round, square or rectangular tube sections. With the help of matrices, various types of steel sections can be manufactured from a wide range of basic geometric shapes.En savoir plus -
QUELLE EST LA DIFFÉRENCE ENTRE LES TUYAUX EN ACIER ET LES TUBES EN ACIER ? -Tuyaux en acier ERW
Les tuyaux en acier sont produits aux États-Unis depuis le début des années 1800. Un tuyau est une section creuse à section ronde, principalement conçue pour le transport de produits tels que des fluides, des gaz, des pellets, des poudres, etc. Mais les tuyaux en acier sont utilisés de diverses manières. Ils sont utilisés sous terre pour transporter l’eau et le gaz dans les villes et villages. Ils sont également spécifiés dans la construction pour protéger les fils électriques. Les tuyaux en acier peuvent être solides, mais légers. Cela les rend parfaits pour les cadres de vélo. Ils sont également utilisés dans la fabrication de pièces pour automobiles, d’unités de réfrigération, de systèmes de chauffage et de plomberie, de mâts de drapeau et de lampadaires, pour n’en nommer que quelques-uns.En savoir plus
