Equipment and Processing Report
PharmTech's monthly newsletter, Equipment and Processing Report, reviews the Editor's Picks for the July 2011 edition from BETE Fog Nozzle and Continental Disc.
BETE Fog Nozzle
Nozzle cleans tanks efficiently
BETE Fog Nozzle’s HydroWhirl Poseidon rotating tank-washing nozzle combines slow rotation and a high-impact spray pattern. The nozzle does not include bearings, which enables it to rotate slowly at a nearly constant speed over the operating pressure range. The slow rotation is intended to clean tanks more efficiently than static and rotating spray balls by increasing the impact of cleaning fluid and increasing spray dwell time on the target surface.
The HydroWhirl Poseidon unit cleans and lubricates itself, and this design is intended to eliminate process contamination. The nozzle is made of PTFE, and the clip-on pin is made of 316 stainless steel to withstand corrosive environments and harsh cleaning fluids. The product is available in six standard models, each of which offers eight connection options. The nozzle is appropriate for tank diameters as large as 22 in. in pharmaceutical applications that require low water, energy, and chemical consumption.
Continental Disc
Pretorqued holder ensures accurate loading and sealing
HPX-PT pretorqued holders from Continental Disc incorporate high-strength steel socket head cap screws to ensure accurate loading and sealing of the HPX rupture disc. The HPX-PT pretorqued holder allows the disc to be correctly fitted in the workshop using precise recommended torque levels before the complete assembly is installed between the flanges in the process-system relief stream.
The unit’s cap screws maintain a seal between the holder and rupture disc to prevent the disc from slipping or leaking in the holder after it is removed from the vessel nozzle or pipe flange for inspection. Once the disc has been inspected, the holder and disc may be reinstalled.
In addition, the HPX-PT pretorqued holder has a durable, tapered seating surface designed to prevent rupture disc slippage and to provide a bubble-tight seal over various HPX rupture disc sizes, materials, and burst ratings. The HPX-PT pretorqued holder is appropriate for active-ingredient processing plants and fill–finish plants that require sanitary connections and environments.
