Most people tend to think of the pipes that deliver water or gas when they consider pipe work. Yet, you see a ton of various types of pipes — and not every one with an unpleasant end on it. Pipes that are made from plastic or copper stand to differ greatly. This article focus on two of these steel pipes: seamless pipe and ERW. Here's how they stand out and how you can use them.
So, in this context, we would be giving you a clear information on An overview of the different manufacturing processes and an introduction to long products: Ruijie Σωλήνας χάλυβα ERW or ERW. Steel pipes are typically made in two processes: cold drawn or hot rolled, and these can be referred to as a seamless pipe (using longitudinal increase the production process)
Seamless pipes are made from a solid round steel 'billet' which is heated and pushed or pulled over the form until the steel is shaped into a hollow pipe. As the process of creating these pipes eliminates any seams or joints, such seamless pipe very solid and durable as well. They can withstand high pressure because they have no weak points. This is the reason why seamless pipes are employed by oil and gas industries, especially in where high-pressure applicability needed like transportation of crude oils.
ERW pipes, on the other hand are fashioned using yet another method. This starts with rolling a flat sheet of steel into an upright tube. The rolled sheet is then welded along its edges with an electrical current. While this welding process does produce a seam, which can make Ruijie ERW pipes slightly less strong than seamless pipes. Typical applications of ERW pipes are in construction and plumbing industries that do not require high pressure, just like the oil and gas pipe line.
Seamless pipe is best for only particular applications like high pressure and elevated temperature systems. These pipes are built to be durable, can they carry materials safely in the vacuum. Nonetheless, in the event that you are working on a venture wherein both temperature and pressure aren't as high and using an ERW για σωρούς σωλήνων από χάλυβα would spare money to buy it. Saving you money but getting the job done.
Seamless and ERW pipes are produced by using the different methods, so each has its benefits. Welded seams, the perfect environment for bacteria; Seamless pipes are manufactured without any welding joints hence there is no possibility of leaking. Further it remove sources that can create spots gathering rust and unclean), seamless approach requires less cleaning). It makes them stronger in this department. In the case of ERW για Πετρέλαιο και Αέριο, they can be conducted in a faster way since they are welded through electricity so it is considered as an electric welding.
In terms of price, Ruijie ERW pipes are usually cheaper than seamless types. The size of the ERW pipes has a wider range; in general, small diameter are less than 16 inches) is usually straight seam welding and large-diameter (above sixteen inches), there LSAW processing. And for these sizes, the ERW Για Ύδρευση και Αποχέτευση process needs fits with larger quantity. Nevertheless, even although you have this kind of pipe and your high strain isn't too excessive but nearly there.
