Our production

The Ring Billet Plant produces and sells flat steel and butt-welded steel flanges up to 2350 mm outer diameter and nominal pressure up to 25.0 MPa, pipe fittings, steel flange plugs, steel rotary plugs, oval and octagonal steel gaskets from various steel grades and grades strength.

Successfully developed and put into production products for parts that complement ball valves KSh, according to individual customer drawings, namely, steel blanks of parts: KSh body, KSh branch pipe, KSh flange, KSh plug (ball), KSh saddle with preliminary machining.

The technologies used in production make it possible to produce high-quality circular blanks of square cross-section and shaped blanks with a repetition of the outer contour of the part with minimal allowances for machining to save metal.

Overall dimensions of products:

• outer diameter - up to 2350 mm;
• wall thickness - up to 330 mm;
• height (length) - up to 500 mm;
• weight - up to 2200 kg.

Produced steel grades:

• carbon steels: 10, 15, 20, 20K, 20KA, 20YUCH, 25, 30, 35, 40, 45, etc.,
• low-alloy steels: 09G2S, 10G2, 10G2S1, 16GS, 17GS, 10G2FBYU, 40H, 20G, etc.

Mandatory heat treatment of all manufactured products is established by the manufacturer depending on the required mechanical properties in accordance with the requirements of design documentation for the part and is aimed at relieving internal stresses, leveling the internal structure, and grinding grain.

The main modes of heat treatment:

• Normalization - temperature 900-920 ⁰ С
• Hardening - temperature 900-920 ⁰ С
• Vacation - temperature 600-680 ⁰ С
• Annealing - temperature 840-880 ⁰ С

Mechanical restoration

The machining workshop is equipped with universal metal-cutting, milling and drilling machines for preliminary machining under the control of ultrasonic testing of blanks and final machining of parts.
