OREANDA-NEWS. January 4, 2013. The non-magnetic drill collar steel independently developed by TISCO gains competitive advantages with the high, medium and low categories, and takes the lead in the product seriation of non-magnetic drill collar in China. Till now, the products have brought significant economic benefits, the realized profit is more than 6 million Yuan.

Petroleum and petrochemicals are global strategic materials and draw much attention over the world. The rapid development of the national economy in China also provides a vast market for petroleum and petrochemicals. The increase of the demand for petroleum stimulates the development of the oil production. According to market conditions,TISCO made in-depth analysis of the production process requirements of the non-magnetic drill collar steel and established the SBU in 2011 to develop non-magnetic drill collar steel. Especially the 1800 ton radial forging machine that was put into operation in the Profile Plant can meet the performance requirements for accuracy, performance, hardness, magnetic permeability and inter-granular corrosion of the steel.

The non-magnetic drill collar steel, with high strength and toughness, non-magnetic and fatigue resistant properties, is a value-added product in the drill collar product series. They are mainly used in positioning and monitoring during petroleum drilling.
