Profile: JB Tubes BV specializes in providing pipes, tubes and other hydraulic products (hydraulic cylinders). We offer a complete range of hydraulic line pipes in carbon and stainless steels. We also offer hardchromed bars and tubes, seamless/welded cold drawn and hot rolled tubes. We can supply the same tubes as cylinder format either honed or rolled condition (carbon and stainless, tolerance H8 to H11). Our hard chromed plated bars and tubes are available in different versions. Hard chromed plated are mainly used as piston rod for hydraulic cylinders. Because of their surface hardness (< 66 HRc), outside roughness (Ra max. 0,25) and straightness, chromed bars are also used in linear motion and other applications. Due to chrome layer, the chrome plated bars and tubes can successfully be used in applications working in extreme conditions, for example the chemical industry with exposure to aggressive agents, mining equipment, oil and gas, aerospace and the marine environment.
