Norsok-standard oil and gas products

Due to the rugged demands of the North Sea and the depths at which the exploration of oil and gas took place, the oil and gas industry was faced with many challenges in the pioneering days of the late 1960s and early 1970s.

Based on the experience and expertise gained since the start of the Norwegian oil and gas adventure, the Norsok standards were developed to ensure the quality of offshore oil and gas exploration. The standards reference internationally recognized values and implement requirements that enhance the quality of the material, making them suitable for the stringent environment and stresses experienced in the North Sea, and offshore exploration in general.

As we are situated in Norway, it is only natural that the Norwegian market is our biggest, which in turn means that our stock meets the Norsok standards, wherever it is acquired from.
