Plant 15 – Tube plant

Plant 15 – Tube plant is the largest tube producer in the Czech Republic.

The key production programme of the Plant consists of seamless tubes, rolled at two Stiefel Mills, producing plain, threaded, flange and oil tubes. The tubes rolled at St 4-10″ and St 140 are produced from continuously casted billets. The seamless oil tubes-casing, pump, drill and pipe-line tubes are the most demanding products.

The three-layer PE coating, including fiber-cement mortar coating (FZM type) are used in gas industry. The Plant carries out the necessary testing as well as inspection devices and up-to-date, non-destructive methods are used for quality testing, guaranteeing the required quality of the tubes supplied.
