Production

Production

High standards of quality

When fab­ri­cat­ing pipe prod­ucts, high stan­dards are applied.

Management system

The inter­na­tion­al man­age­ment sys­tem of ISO 9001: 2015 is valid at our enter­prise.

Quality control

All pipes of large diam­e­ter oblig­a­to­ri­ly should under­go non-destruc­tive con­trol with using ultra­sound, x-ray, mag­net­ic par­ti­cle meth­ods, includ­ing hydraulic tests.

Pipe production technology

The tech­nol­o­gy of pipe pro­duc­tion is cer­ti­fied by the E.O. Paton Elec­tric Weld­ing Insti­tute (Paton Elec­tric Weld­ing Insti­tute named after E.O. Paton of NASU).
