Technical requirements:

1. Chemical composition and mechanical properties all meet the GOST9941-81 standard.

2. The outer diameter and wall thickness tolerance requirements of the stainless steel pipe must meet the higher requirements of the GOST9941-81 standard.
3. All stainless steel pipes need to be tested after passing the ultrasonic nondestructive testing.
4. At least 2 samples are taken for each specification for spectral analysis, mechanical property testing, flattening test and intergranular corrosion testing.
5. It is necessary to provide detailed product production inspection record reports including (raw material original material book, blank material inspection report, cold drawing record, heat treatment record, steel pipe finished product inspection record, spectral analysis record, ultrasonic flaw detection report, machinery Performance and flattening test records, intergranular corrosion test reports, etc.).


Surgut Oil and Gas Corporation (SNG) is one of the three largest Russian oil companies with more than 86,000 employees and is the 11th largest oil company in the world. Since the first discovery of oil fields in western Siberia in 1961, the total oil production in the SNG field has exceeded one billion tons. Today, SNG's oil production accounts for one-eighth of Russia's total oil production, and natural gas production accounts for one-third of total domestic production. SNG also undertakes a quarter of Russia's oil exploration and mining tasks, and oil production is growing steadily year by year. It has made positive contributions to the Russian industry, national defense, railway, aviation and people's lives.
