Tailor-made tool kits for installing and removing the tensioned casing bolts on gas turbines are now available ex stock.
Tailor-made tool kits that include all the tooling and ancillary equipment required to install and remove the tensioned casing bolts on gas turbines are now available ex stock from specialist bolt tensioner manufacturer Boltight. The equipment delivers considerable time-savings by providing effective and reliable nut release during turbine dis-assembly and speedy and accurate re-tightening during turbine assembly.

The kits are proving a popular choice with engineers working on the installation, service and maintenance of gas turbines worldwide. Boltight recently supplied tool kits to power plants in Russia and Algeria. A GE 6FA casing tool kit was sent to Russian Gas Turbines LLC for use on a new plant, located near Rybinsk in the Yaroslavl region. The project is a joint venture with GE. The tools were 'fit and function' tested at GE's factory in Belfort, France prior to delivery.

Another recent order was for the supply of a GE 9FB casing tool kit for a thermal combined-cycle power plant in Hadjret en Nouss, Algeria, operated by SNC-Lavalin. Power at the plant is generated by three GE single-shaft power trains.

Each tool kit is supplied in a durable, site ready metal storage case and includes a full colour, health and safety, operation and maintenance manual. The tools, which are lightweight, durable and simple to use, offer speed, accuracy and safety. They feature the latest technology including long life composite seals, automatic piston return, positive stop to prevent over stroke and oil leakage, pressure cycle counter and gear driven nut run down. A typical tool kit includes single and multi-cylinder stage tensioners, air or electric driven pumps, hoses, sockets, ratchet, spares and connecting blocks.

Explained Boltight's Business Development Manager, Dave Metzger: "Our tool kits are a simple and efficient option for procuring bolt tensioning tools that are matched to the casing geometry, bolts and nuts of a particular gas turbine. Everything an engineer requires is included and ordering could not be easier. We can supply these casing tool kits ex stock for quick delivery. We also offer short and long term rental contracts."

Casing tool kits are available for the full range of GE frames (6FA, 7FA, 7FB, 9FA and 9FB) as well as other OEM supplied turbines including Siemens and Alstom.

Boltight is exhibiting with parent company Nord-Lock on Stand 3031 at Power-Gen International in Las Vegas (8th-10th December 2015).
