ChTPZ Group tests new OCTG steel

11 December 2014 (09:18)

December 11, 2014. Pervouralsk New Pipe Plant (a member enterprise of ChTPZ Group) successfully tested its new 18G1FA steel: this new variety is meant for making hot-worked, cold-resistant oil and natural gas pipes that can meet Rosneft’s standards, the plant’s press service reports.

The pipe ingots were cast at the plant’s own electric steel-smelting Iron Ozone 32 unit.

‘This 18G1FA steel pertains to low-alloy steels. The plant uses it to make two kinds of pipes whose strength grade depends on the specific operating conditions they will have to withstand. Following the rolling and the rolling heat tests, the 219x8mm pipes made of 18G1FA steel were ascribed strength grade L390. After the pipes were thermally treated at the plant’s Finishing Center, the strength grade was upgraded to L415,’ the press service says.

Cold-resistant pipes are primarily meant for the development of oil and gas deposits and transportation of these in very severe climates.

It took the plant one year to master and test the 18G1FA steel production. The experimental batch delivered to Rosneft amounted to 80,000 kg. The plant is currently busy getting the new product certified.
