  There are many advantages of using  hollow piston rod .On the one hand, it can obviously reduce the weight of the whole structure. On the other hand, it can further improve the use performance of mechanical equipment. In other words, with the emergence and application of hollow piston rod, the equipment has a greater development space in the performance and use. However, to give full play to the use performance of  hollow bar ,first of all, it needs to ensure its straightness. In the process of straightness detection, do you know which methods can be used? Let's get to know the details below! In general, to accurately detect the straightness of the hollow piston rod, four different methods can be selected. The first method is the pitch method. Usually, this method is mainly used for measuring long parts. For example, when the piston rod is divided into several small sections, the relative readings of each segment can be measured with the aid of the level, auto...

  Metal tube and hollow bar are used in a wide variety of structural applications. They offer a cost advantage to solid metal bar stock, while weighing less than a solid bar of the same material and size, yet still providing much strength. While tube and hollow bar can be similar in shape, we will look at the difference between tube and hollow bar. The difference between tube and hollow bar include: Manufacturing Process Quality Materials MANUFACTURING PROCESS A big difference between welded tubing and  hollow bar  is how the two are made. Tube is made by taking slit coils of a base metal and running it through a tube mill, which is a series of dies that form the slit coil into a tube shape; either round, square, or rectangular for example. Once formed into the desired shape, the edges are joined together with a weld. The welding process can vary depending on the material type, material thickness, and preference of the manufacturing team. Typically, high frequency welding...
