  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...

  S45C hydraulic cylinder chrome plated shaft   mainly used for hydraulic equipments and construction machinery . The Quenched and Tempered Shafts are fabricated using quenched and tempered S45C material and latest machinery. The bars undergo rigorous processes like pilling, quenching and tempering, straightening, grinding, polishing, hard chrome plating and finishing under the supervision of experienced engineers. The mechanical property of the Quenched and Tempered Shafts is better than the Hard Chrome Plated Piston Rods. The Quenched and Tempered Shafts are more qualified under adverse operating environment owning to its excellent mechanical property such as robust construction, elevated durability and high tensile strength.

  A  hydraulic cylinder ,is a mechanical actuator used to give linear force through a linear stroke. It can be used in a variety of ways, and is commonly seen in manufacturing machinery, civil engineering, and construction equipment. There are two main types of hydraulic cylinders: tie rod cylinders and welded hydraulic cylinders.  Tie Rod Cylinders Tie rod hydraulic cylinders are not as complex in terms of design as welded body cylinders. Tie rod hydraulic cylinders use high-strength threaded steel rods in order to hold the end caps to the cylinder barrel. Small bore cylinders typically have four tie rods whereas larger bore cylinders can have as many as twenty tie rods in order to withstand the forces produced by the cylinder. Welded Body Cylinders Welded hydraulic cylinders have no tie rods. Instead, the barrel is welded directly to the end caps and the ports are welded to the barrel. The front rod gland is generally bolted or threaded into the cylinder barrel, which a...
