The installation of a Danobat VL bandsaw has enabled English manufacturer Bel valves (http:www.belvalves.co.uk) to improve cutting operations in its valve production process. It has also managed to dramatically reduce cutting time, and material waste is also appreciably lower than in the previous process.
Bel Valves, based in Newcastle, England, is a sector leader in the design and manufacture of critical oil and gas valves for both surface and subsea applications. It concentrates its efforts on serving evolving markets that demand the very highest quality and reliability. The company has some 50,000 valves installed across the globe, some of which operate in the most inhospitable environments on the planet, often in ultra-deep waters of up to 3,000 metres (10,000 feet) and under high pressures as well as extremes of temperature.
It recently decided to install a Danobat VL bandsaw to upgrade cutting operations during production of its 61 cm (24″) diameter split gate 4A topside through-conduit valves.
Although the existing process used a vertical bandsaw, it wasted a great deal of material, typically deviating up to 1/2″ on either side of the blade from its true path, requiring a considerable amount of additional post-cutting machining in order to form a true surface.
Thanks to the Danobat VL vertical bandsaw, the cutting time for this product has been spectacularly reduced from 18 hours to just 6 hours, whilst simultaneously reducing waste material due to the appreciably more accurate cutting path, amounting to cost savings in the region of £1,500 per valve.
