length measurement, testing and marking). Also included in the line is a magnetic bundler for stacking pipes in hexagonal bundles. On the upsetting line, tubing and drill pipes in the size range from 60.3 to 127mm are upset at the pipe ends. The scope of supply includes an upsetting press with an upsetting force of 2,500kN, with upline induction heater and the necessary inspection and testing stations. The testing line is used to inspect the quality of the heat treated and non-heat treated pipes. Longitudinal and transverse flaw tests are performed in accordance with international standards. Upset and plain-end pipes in the size range from 60.3 to 219.1mm are heat treated on the heat treatment line. The scope of supply includes a hardening furnace and an annealing furnace (supplied by an Italian subsidiary of SMS Meer), quenching facilities with the associated water management system, a hot straightener with the necessary contraflow cooling beds, and the interconnecting transport facilities. With this new finishing centre, the Pervouralsky Novotrubny Works pipe mill is now in a position to produce pipes of the highest grades and qualities.

Large tube borer boosts production

Keetons, UK, has recently installed and completed startup of a new tube boring machine. With a 1,200mm diameter chuck, it is the largest of the company’s 4 tube boring machines. The machine is able to bore thick walled tubular components from 2-10m in length, with bores from 60mm to over 600mm diameter. The machine also has a 500mm diameter hollow spindle to handle extra long jobs. Delivery of this machine follows numerous other developments including the introduction of a second 8m honing machine.

80 years. Despite recently increasing capacity and although boring jobs over 1,000mm long are normally undertaken, the company can also machine smaller items. The company’s smallest borer can handle bores of 20-70mm diameter from solid bar in lengths of up to 4m.

Complete finishing centre brings advanced tube production

OAO Pervouralsky Novotrubny Works, part of the ChTPZ Group, Russia, has placed an order with SMS Meer for the supply of a complete finishing centre for its existing pipe plant. The finishing centre is designed for an annual capacity of 75,000 to 90,000t and consists of a tubing/casing line, testing line, upsetting line and heat treatment unit. The whole complex is coordinated and controlled by a superordinate computer system. Tubes in the size range from 60.3 to 177.8mm can be finished on the tubing/ casing line. The line essentially comprises four pipe threading machines, a two-head hydrostatic pipe tester with a maximum pressure of 150MPa, two drifter units for checking the pipe inside diameter, and the automatic measuring system (weighing,

› The boring of 475mm x 9m thick walled tubes used for the international energy market

One of the company’s deep hole boring machines used for boring solid bars and forgings has also met with success. The machine can bore jobs up to 6.5m long, but has a 4m-bed extension planned to increase the number of machines with capacity of over 10m. Keetons has been producing and processing thick walled tubular components from seamless tube and solid bar for over

Commissioning of the whole finishing centres is scheduled for the end of 2008.
