An NISOC official, Naser Kheradmand, told Shana that the items were all designed and manufactured by Iranian experts operating at the NISOC of other Iranian knowledge-based enterprises.
He said the items will be officially unveiled during the three-day exhibit that is being held in the southwestern city of Khuzestan later in November 7-10.
Kheradmand, who is the director of items procurement and affairs department of the NISOC, further said the items are among the ones underlined by the Iranian Ministry of Petroleum as prioritized items to be constructed domestically.
Iran selected 10 groups of petroleum items and parts in 2014 for domestic manufacture in a bid to bolster its industrial capabilities in the sector.
The parts include wellhead equipment, control valves, various kinds of bits, and different kinds of pipes.
