JST 340# casing threading production line was officially put into production in 2009. Most of the threaded casing produced from this line belongs to API conventional type. However, OTTM special threaded casings (P110 steel grade, 323.9 mm × 12.4 mm) ordered in early May has Russian standard special thread. Customers require higher thread and various technical parameters, which increases the risk and production difficulty.

Our OTTM special threaded casings are highly appraised by customers for their high quality and production efficiency.
