Self-contained blast room upgrades production

Production facilities at specialist pipeline valve manufacturer, Oliver Twinsafe, have been upgraded with the installation of a self-contained Enviraclean blast room with abrasive recovery system and high-performance sound insulation from Hodge Clemco.

The chamber measures 4m long x 3m wide x 2.5m high and has double access doors at one end to accommodate large components. The walls are lined with rubber curtains to reduce abrasion, and modular double-skinned panels have an acoustic lining to reduce the noise that can be heard outside the chamber during blasting. Air inlet ducts and exhaust outlets are designed to provide effective ventilation in order to ensure good visibility for operators. Media is projected by a 2452 SGV blasting machine via a 3/8 inch (10mm) ID tungsten-carbide-lined nozzle, which is designed to maintain maximum blasting velocity, uniform abrasive distribution and high work-rate over a long operating life.

Abrasive is recovered for re-use by means of a pneumatic suction filter unit linked to a sweep-in hopper in the floor of the blast room.
