The most widely used in the production of oil and gas equipment are forged discs with a central hole, discs without a central hole, as well as rolling rings. Parts such as bottoms, collar flanges, fittings, rings, nozzles, body parts and bandages are made from this type of blanks.
Forgings are made in accordance with the requirements of GOST 8479-70, GOST 25054-81 from various grades of steel: carbon, tool and structural alloyed and others depending on the required properties of the parts that will be produced from these blanks. The weight of forgings can be practically any - from several kilograms to several tons, depending on which parts the workpiece will be used for. In terms of cross-section, all forgings are divided into square, rectangular and round forgings.
The Ring Billet Plant supplies forgings with overall characteristics:

Heat treatment of the forgings provides the mechanical properties specified by the technical specifications for the forging. Heat treatment of steel forgings is annealing, normalization and quenching followed by tempering.
The Ring Billet Plant manufactures and sells a wide range of round and rectangular forgings. Here you can order forgings according to your requirements with preliminary machining.
Forgings are made from high-quality raw materials in compliance with the technology, undergo ultrasonic testing, at your request, and are supplied with quality certificates.
