The process of galvanization was first discussed by scientists in the 1770s. It has been nearly 60 years before it was finally introduced in the 1830s. One French engineer named Stanislaus Tranquille Modeste Sorel took out the first patent for the process in 1937, and began manufacturing it soon after. By the 1850s, Europe was producing galvaniz...

Cold-formed steel, like most other type steels, which is formed with rollers and presses so as to make it the desired size and shape and it is not formed with heat. Cold rolled steel pipe is lighter than other steel pipes because of the cold rolling processing and it is also somewhat elasticity. Compared with hot-formed steel which is difficult ...

As a rule, following the market-oriented economic law, how to plan the production capacity of steel pipe manufacturers to a large extent depends on the feedback from needs in steel market. On the other hand, the one major drawback of the market-oriented economy itself is that the production capacity in demand is likely to be in short supply, whi...

In the metalworking industry, we can often find a milling machine which is used as a tool to shape solid products by eliminating excess material so that the product can form a desired type. This machine can be used for a number of complicated cutting and welding operations such as slot cutting, drilling and it can also be used in manufacturing b...

As we all know, welded steel pipe occupies an important position in the modern production activities and daily life. However, we have to do more thinking to work out the situation when encountering the shrinking market sometimes. Nowadays, with a highly competition in steel market, there appears to tend towards overproduction. In a sense, steel ...
