DEVELOPMENTS NEW EQUIPMENT, PROCESSES, & MATERIALS Plastic-Lined Piping Products DowChemical Co. Midland, Mich. Dow’s Conquest flangeless connections is a new method of joining components that can eliminate virtually all flanged connections in a plastic-lined piping system. Using mechanical couplings to achieve permanent, completely sealed pipe-to-pipe and pipe-tofitting joints, Conquest flangeless connections can be fabricated at the job site in about half the time it takes to fabricate and install conventional flanged plastic-lined piping connec-

just 2-3 lb, significantly reducing powder loss and the volume of waste generated by the user. Manufactured from 100% synthetic, continuous filament media, ECOSpun appears seamless, and offers virtually zero possibility for the release of fiber particles into the powder stream, which is the leading cause of defects on powder-coated parts. When the EC0 filter is used as a primary filter device, the need for final filters (such as HEPA filters is nearly eliminated. The ECOSpun filter is washable and reusable indefinitely, and washing does not compromise filter performance. The ECOSpun media is chemical and abrasion-resistant. EC0 powder cartridges are direct replacements for all filters used in powder coating systems. Standard and Silver Shield (aluminized) cartridges are available. The filters offer low noise, long life, and chemical and abrasion resistance. Circle 402 on reader information Cerd

tions. The connections eliminate a major source of piping system leaks, including leaks of fugitive emissions, and ongoing monitoring, retorquing, and other maintenance requirements of flanged connections. A plastic-lined piping system using the flangeless connections can be engineered using 1-4in. swaged pipe sections and three plastic liner types, including polypropylene (PP), polyvinylidene fluoride (PVDF), and perfluoroalkoxy (PFA), for handling a broad range of corrosive or high purity fluids at extreme temperatures. Matching fittings designed exclusively for use with Conquest connections are also available, and two types of adapters integrate a flangeless plastic-lined piping system with conventional flanged components.

Finishing Blast Rooms Empire Abrasive Equipment Corp. Langhorne, Pa. A broad selection of blast rooms designed for environmentally safe fin-

ishing of large parts is available from Empire Abrasive Equipment Corp. These rooms offer the choice of fielderected or package designs as well as a wide range of media-recovery options, including screw and vibratory systems ranging from single troughs to full floors, as well as economical sweepchute and shovel-chute arrangements. Media recycling can be performed

through an air-wash or cyclonic device linked to either a cartridge-type or baghouse dust collector. In addition, these rooms minimize environmental hazards by confining the blast process within a sealed enclosure. Package rooms, which can be set up for operation in as little as one day, come preassembled in sizes up to 12lY&ft wide, 20-ft long, and lo-ft high. Fielderected enclosures, featuring boltthrough construction, are available, starting with a 7%-ft wide by IO-ft long by 8-ft high room, expandable in width and length by 2i/&ft increments and in height by 2-ft increments.

Electrically Heated Cabinet Oven The Grieve Corp. Round Lake, 111. The Grieve No. 718 is an 850°F electrically heated modified Model HA-850 Cabinet Oven, currently being used to bake paint samples on metal panels. The workspace dimensions of this oven are 20 in. X 20 in. X 20 in. A 1OKW heat input is provided. A 680 CFM recirculating blower, direct driven by a L/2hp motor, provides horizontal airflow. A IO-rpm motorized stainless steel turntable is suspended through the roof with 1 i/&in. stainless steel studs on the turntable surface to hold the metal panels being processed. The safety equipment for handling flammable solvents at a maximum operating temperature of 850°F includes manual reset excess temperature controller, separate heating element control contactors, 130 cfm powered forced exhauster, powered forced exhauster air flow safety switch, recirculating blower air flow safety switch, and a purge timer.
