With a purpose of obtaining high qualitative and reliable products our plant is equipped with the most modern inspection facilities, equipment with active inspection, quality-control laboratory with special equipment so for proximate analysis conduction as analytic examining.
The products are 100% tested including:
- the proximate analysis of steel melting chemical composition;
- the ultrasonic test to indicate the defects and nonmetallic inclusions;
- examining micro- and macrostructure;
- Brinell hardness;
- examining mechanical properties (tensile strength, tensile yield, impact strength, elongation, reduction of area);
- thread inspection;
- threaded connections magnetoscopical inspection;
- straightness hole inspection;
- sag of drill pipe.
