Initial situation and requirements
The oil refinery is one of the largest refining facilities in Germany, with a crude oil processing capacity of 17 million tons per year.
During the shutdown period of the refinery, several pipelines were slated to be replaced by newer ones. The corresponding pipe girth welds are traditionally inspected by means of classic film radiography. During this conventional testing method, the facility needs to be shut down as radiation affects human health. Our experts at TÜV Rheinland looked for an intelligent advanced testing method to be carried out during operation in order to reduce inspection time while providing equivalent or even better inspection quality.
|Our clients profit from our dedicated management platform for the cross-regional exchange of technical and operational knowledge.|
In the search to find a solution for the special requirements, our NDT experts from Germany and the Netherlands sent samples to one of our laboratories to be tested using the radiography method - L0 . Another laboratory from our network tested the samples applying the advanced ultrasonic method. Results found by both methods were consistent, so the client selected the proposed advanced NDT technique .
The client was able to save resources as parallel activities related to the shutdown were carried out during inspection. With our help, the NDT part of the shutdown period was shortened by one week, which meant enormous savings in both time and resources.
Benefits for the client
The client profited from:
• Tailored NDT method solving a special requirement.
• Replacement of the classical film radiography by intelligent advanced ultrasonic testing method.
• Inspections during operation – saving time and resources.
