HANSA‑FLEX revolutionised the service business in the hydraulics sector with the launch of the X-CODE on 1 June 2004. The simplification of the spare parts business by means of the X-CODE is an unparalleled success story that continues to the present day. By the end of 2009 the X-CODE had been used 4,275,714 times. In 2022, eighteen years after its introduction, the 25,000,000th X-CODE was issued. On average this means around 1.4 million labels a year, around 3,800 per day. The XCODE service system was developed by HANSA‑FLEX in order to help its customers, who already numbered around 130,000 at the time, even more quickly when it came to replacing hydraulic hose lines. Previously, technicians had to dismantle the hoses to be replaced and have them identified by specialists from the supplier in order to source the correct spare parts. This process took up a lot of valuable time, especially in remote locations such as oil platforms. The X-CODE system made it possible for the first time to clearly identify the relevant components using the six-digit alphanumeric code, which could even be transmitted to HANSA‑FLEX by untrained employees. Thanks to the central database each branch was able to access the specifications of the ordered spare part and immediately start assembling it. The X-CODE could be used to mark not only hose lines, but also pipelines, power units and all other component groups.
