Dürr NDT portable imaging plate scanner ensures highest quality in specialised pipe production
19/11/2024
Dee Piping Systems, founded in 1988 and headquartered in Haryana, India, is one of the biggest manufacturers of specialised pipes in the region, employing over 1000 people. As the largest player in process piping solutions in India by installed capacity, the company has a total manufacturing area of more than 350,000 m2 spread across seven manufacturing sites.
Dee Piping has been a user of Dürr NDT’s HD-CR 35 NDT system since 2021 at its Palwal Unit III facility and utilises it in quality control for weld inspection, as well as for confirmation of pipe wall thickness. Both X-ray and isotopes such as Selenium-75 and Iridium-192 sources are used to expose pipes of different thickness. Different imaging plate sizes are used to accommodate the different pipe or weld sizes: 10 × 24 cm, 18 × 24 cm, 10 × 48 cm and 35 × 43 cm, for acquisitions of up to 30 images per day.
Comparing the HD-CR 35 NDT to conventional film radiography, digital radiography saves time and does not require physical space to store the images. The operators are extremely pleased to eliminate the usage of dark rooms and chemicals in order to develop films, as was the practice in the past.

With an expanding business that requires higher throughput, Dee Piping has taken a recent decision to invest in D-Tect X, Dürr NDT’s latest inspection software suite. Mr M L Bhatt, the Head of Department, commented: “The D-Tect X user interface is very intuitive and my operators like the X-Filter that enhances images with a single click. The fact that we can perform analysis on an image while scanning a new one simultaneously using the same computer saves us a lot of time and money.”
Mr Vivek, one of the users, added: “The signal-to-noise ratio feature with built-in options of adapting to different ASTM standards gives us flexibility when providing reports to different clients. Moreover, the automatic image quality indicator (IQI) detection tool made detecting the correct basic spatial resolution easier compared to the past.”
With upcoming developments in artificial intelligence and archiving images in the cloud, D-Tect X is designed not only to satisfy the needs of data digitisation, but also digitalisation and digital transformation.
Dee Piping Systems is also fully supported by India-based Blue Star Engineering and Electronics Limited, which performs annual maintenance and any other required service activities to ensure the system is always running per specification.
