ERW = Electric Resistance Welded ERW THIS TYPE OF PIPE IS MADE BY WELDING TWO PIECES OF STEEL TOGETHER. It utilizes electricity in order to heat the edges of steel to such a degree that they can be fused together. It is this welding process that leads to the formation of ERW pipes. In contrast, "seamless" pipes consist of a single solid piece of steel. First, the steel is granulated or sliced and then heat-treated, after that it is squeezed to mold a continuous tube free of seams or joints. It means that there are no vulnerable joints in the case of seamless pipes.
What is the reason for choosing one type of pipe over the other? While both ERW and seamless pipes have their merits, they also come with risks. A case in point is ERW pipes are generally inexpensive to manufacture compared with seamless pipes. You may find this quite useful when trying to find savings on your project. But since ERW pipes are welding type, theyare weaker and less long-lasting than seamless pipe. That means they can be more prone to breaking or rusting, at least under harsher use cases.
Well, let's discuss the production process of these two types of pipes. Making ERW pipe starts with rolling steel into a flat sheet. That flat sheet is then rolled into a tube shape. Following that, the sides of the sheet are joined along and with electrical currents so that they take on a final shape as pipe. After the welding is complete, the new pipe will be pressure tested to ensure it is up to all safety standards. It is extremely critical to test the pipe and make sure it is safe for use.
But the process is different for seamless pipes. The steel is first placed in a furnace tempered to extreme temperatures until it is soft and ductile. Then, it is processed into a tubular form through the hot rolling process. This method produces an uninterrupted bone tube without seams. Once the pipe is formed, it are then also tested for defects and found to be safe for usage. The quality control process guarantees that the seamless pipe will seamlessly work with its intended applications.
There are some important factors that you need to consider whenever you have to choose between ERW and seamless pipes. For starters, think about the setting in which the pipe will be used. In case the pipe is supposed to be under high-pressure or in a high temperature, probably you would prefer use a seamless pipe. Seamless pipes can better cope with these difficult conditions. Conversely, however, if the pipe is intended for lighter duty applications such as in a household plumbing system, an ERW pipe is adequate.
An operational consideration, pipes do impact your bottom line. So, if your budget is little off the cost, ERW pipe might be the right choice for you. These are typically lower-cost to manufacture and allow you to save more volume for your project. That said, if you can afford to pay a bit more for a heavy duty and reliable pipe then maybe consider going seamless as the long run option. You can avoid repairs or replacements down the line by spending a little more on a better quality pipe.
If you have decided to go with any type of pipe, it is essential that it be properly installed, used and maintained. Leakages can also happen with an ill-manufactured pipe or it will rapture. In fact, it may cause destruction of property and pose a safety hazard for you and others. When installing your pipe, it is best to get the help of a professional plumber or contractor to make sure that you install your pipe correctly. They know how to get the job done right.
