PAMIR-300 (ARINA-11) is the latest modification in the series of portable pulse flaw detectors of the ARINA series.
Its distinctive feature is a significantly higher radiation power compared with the ARINA-9 device with smaller dimensions and weight.
In addition, the continuous operation time of PAMIR-300 (ARINA-11) is 30 minutes per hour instead of 15 minutes, as in the currently available models from ARINA-3 to ARINA-9.
These advantages allow the use of PAMIR-300 (ARINA-11) to control the welding of gas trunk pipelines of the largest diameters using the panoramic method when using D7 X-ray film with lead reinforcing screens. At the same time, the exposure of the 1200 mm pipe radiography is 6–8 minutes, and the pipes 1,400 mm take 15–20 minutes. Naturally, the pipe of smaller diameters can be controlled in just a few minutes, which ensures the continuity of control during the working day.
The PAMIR-300 (ARINA-11) device was developed in 2011 and will be mass-produced starting from the first quarter of 2012, jointly by two companies Spectroflash LLC and Spectroimpuls LLC. Delivery of the device will be carried out only under contracts with LLC "Spectroimpuls".
