As chemical and related processing technology becomes more complex, the need for safe and efficient support equipment for these operations becomes more critical. And while Protectoseal is known throughout the industry for providing a broad line of standard devices, we are also experts in providing unique and effective solutions to specific problems.

Manufacturers of the equipment required by these industries are expected to be “development-oriented" in their engineering and manufacturing functions. Protectoseal understands this demand for new and improved equipment and has the entrepreneurial spirit and technical capabilities to meet such demands.

In the area of Vapor and Flame Control Equipment, among others, educated customers have come to depend on Protectoseal for an open-minded approach to their demanding requirements. We know how the investigation of experimental processing techniques, construction of pilot plants, re-evaluation programs, and detailed research projects are common in the processing industries. As a result, we are a trusted manufacturer of non-standard or “special function" equipment.

Protectoseal welcomes the opportunity to apply our technical and manufacturing experience and capabilities to develop real world, practical and cost effective solutions to your unique problems. Contact our highly trained Sales Representatives or our professional Engineering and Design staff. They are at your disposal to help ensure the safe and profitable operations of your facilities.

PROSHIELD Coating for Controlling Unwanted Buildup

Challenge: A leading global supplier of resin chemistries for composites and cast polymers was facing operational difficulties due to a rapid and frequent build-up of polymerized styrene in their vapor control equipment. Such build-up if not managed properly, could prevent the equipment from properly venting putting the safe operation of their storage tanks at risk. Weekly inspections and significant maintenance hours were often required to remove the hardened polymer. The maintenance process would be time-consuming, often causing unintended damage their vapor control equipment.

Solution: Protectoseal recommended an end-of-line pressure / vacuum conservation vent offered with our PROSHIELD coating option. This coating was applied to all wetted surfaces with the primary objective of controlling or reducing polymer formation. The trial unit was successfully field-tested for over 10 months and exhibited little to no buildup during that period.  The PROSHIELD coating option helped this client significantly reduce their maintenance costs and completely eliminated unnecessary replacements. Overall, the solution facilitated the achievement of a safer storage tank operation.

36" Steam Jacketed Emergency Vent

Challenge: A customer required a 36" End-of-Line Pressure Vent that could be steam heated to minimize the possibility of product condensing and solidifying on metallic vent surfaces. The steam jacket chambers were to be hydrostatic tested at 700 PSIG. All wetted parts were to be SS316. Positive Material Identification was to be provided for all SS316 components. The vent was to be set at 1.5 inches water column pressure.

Solution: Protectoseal designed and fabricated a special 36" vent for the steam jacketing application. All components and assemblies were modeled and analyzed using state-of-the-art software prior to fabrication. The vent was designed with steam chambers on the seating surface and the weather hood. Internal components were designed to maximize the effectiveness of the heating chambers. Each unit was fully tested for strength, setting and function prior to shipment. All SS316 components were subjected to independent Positive Material Identification and detailed reports were provided in accordance with Protectoseal's exacting specifications.

24" Fiberglass Vent with Electronic Lift Indicator

Challenge: A customer required several 24" pipe size pressure Fiberglass Reinforced Plastic (FRP) vents manufactured from Derakane 470 Vinyl Ester Resin. The vent had to be equipped with an electronic sensing device that would send a signal to a remote location in the event the vent should lift. The signaling was an integral part of an EPA mandated monitoring program. Each vent had to be tested under flowing conditions to verify proper lift of the pallet assembly and signal activation.

Solution: Engineers modified the design of a standard Protectoseal 24" FRP vent so that a switching trigger would be activated with very slight pallet assembly lift. This switch would provide a signal to a designated remote monitoring source. The vent was set to the customer's requirement of 8" water column pressure.

Each vent was then mounted to the test tank of Protectoseal's Flow Test Facility. This facility is capable of generating in excess of 500,000 SCFH of air flow at low static pressures. Each 24" vent was then tested to verify pallet assembly lift and signal activation under flowing conditions. The results of these tests were documented in written reports and in video presentations. Customer on-site witnessing of testing was waived after review of the documentation was provided.
