PNTZ Improves OCTG Quality Control

UrBC, Moscow, September 15, 2016. ChTPZ Group’s Pervouralsk New Pipe Plant (PNTZ) launched an additional magnetic particle testing unit to ensure better quality control of OCTG pipes, the company press service reports.

The new equipment is meant for testing pipe couplings for defects: these are detected with the help of ferromagnetic particle indicators which point to stray magnetic fields over a defect. The additional testing unit increased the plant’s overall production capacity and cut down on the quality control testing time. The unit cost 50m RUR to buy.

Magnetic particle testing is an efficient way to spot product defects and an obligatory part of QC procedures for oil country tubular goods that meet GOST and API requirements, the most popular standards in the oil and gas industry. There are currently five MPT units in use at the plant, with their overall testing capacity at more than 200,000 couplings and ends of casing and oil-well tubes a month.

PNTZ can supply its couplings to customers with or without the OCTGs to go with them. The plant guarantees one hundred percent quality for its partner companies and end users such as Rosneft, Gazprom, Surgutneftegaz, and Bashneft.
