1. The ID honed & OD chromium plated seamless tubes are used for the telecsopic hydraulic cylinder, such as the hydraulic mechanism adopted on the garbage trucks, fir rescue engines, lifts, multilevel car park servos and the like.
2. Hollow pipe the same as hard chromium piston rod, it lighter than piston rod weight and higher strength, making it less prone to bending, and can be used as the reflow pipe.
