The straightness of seamless steel hydraulic tubing has a significant impact on pipes used for precision machinery and hydraulic cylinders. High straightness accuracy can improve customers post-processing efficiency and reduce production costs. One of the biggest concerns when purchasing seamless steel hydraulic tubing is the possibility of receiving pipes that cannot be processed, leading to waste in production costs and delays in delivery. Therefore, straightness in seamless steel hydraulic tubing is of utmost importance.

 

Outdated straightening equipment with poor straightening accuracy cannot significantly improve the straightness of seamless steel hydraulic tubing, only achieving a visual straightness without bends. Such straightness requirements for seamless steel hydraulic tubing are not sufficient for precision machining industries. For applications like hydraulic cylinders, high straightness requirements are needed to maintain consistent inner diameters. Outdated straightening equipment cannot meet these requirements. We have advanced straightening equipment that can control the straightness accuracy of seamless steel hydraulic tubing to within 0.5mm/m, meeting the production requirements of hydraulic cylinders.

 

Seamless steel hydraulic tubings are produced using two different processes: precision rolling and cold drawing. Generally, seamless steel hydraulic tubing produced through precision rolling have better straightness than those produced through cold drawing. This is because precision rolling is a form of rolling and does not subject seamless steel hydraulic tubing to significant elastic deformation. However, in the cold drawing process, seamless steel hydraulic tubing are stretched, resulting in substantial elasticity. When the seamless steel pipe is removed from the drawing machine, plastic deformation occurs.

 

These are the factors that affect the straightness of seamless steel hydraulic tubing. Straightness is a crucial parameter for pipes used in precision applications, and the better the straightness, the higher the yield during post-processing. For fields such as hydraulic cylinders and mechanical components, high straightness requirements are essential.
