Vyksa Steel Works – Casings

Electric welded casings are produced by Vyksa Steel Works and fully comply with API 5CT requirements.

Consistent quality of pipes is ensured by optimised production process. Pipes are high-frequency welded with constant current lead.

Pipe quality control is ensured by automatic control of welding, ultrasonic inspection of pipe weld and body, and tracking system.

Electric-welded pipes are supplied with Buttress threads, short (STC) and long (LTC) round threads. To increase tightness of Buttress threads pipes can be supplied with a fluoroplastic sealing ring. Tightness of pipes and threads is tested by means of hydraulic testing of each pipe. According to Customer’s requirements a protective coating can be applied on the external surface of pipes.
