Flange Spray Shields
A flanged joint in acid or caustic service is where a leak shows itself first, and a spray shield is what keeps that leak from reaching anyone. We supply Drake Specialties safety spray shields with our lined piping systems: for every flange on the line, and for the valves, expansion joints and unions between them.
- Fabric shields. PTFE-coated fiberglass or 100% woven PTFE, or PVC, polyethylene or polypropylene fabric; clear for inspection, or solid with a replaceable pH-indicating patch that turns toward red for acid and green for caustic when a leak starts. A PTFE drain nipple on the clear PTFE shield carries a caught leak away to a safe place instead of leaving the flange sitting in it. The usual choice on lined pipe in acid and caustic service. The coated PTFE styles are built on glass cloth, which hydrofluoric acid attacks (the PTFE itself is fine), and HF attacks 316 stainless too, so for HF we recommend the 100% woven PTFE shield, which has no glass, or polypropylene, rated to 200 °F (93 °C), on lines near ambient.
- 316 stainless shields. Style I latches on in seconds without tools; Style II, with overlapping slotted edges, is the choice for high temperature, high pressure, steam and flammable service. Mesh shields turn a spray into a visible drip.
- Flange protection. Band protectors and nut and bolt caps keep salt spray, sand and chemicals off flange faces, gaskets and studs. These protect the joint from corrosion; they are not spray shields.

Glass Lined Pipe & Equipment
Glass lined steel for glass-contact service, ½" through 48", split ring flanges drilled to ASME B16.5 (150 or 300 lb) or DIN 2873. European-made under the PED, ISO 9001.
- Pipe, spacers, elbows, tees, crosses, laterals
- Reducers, reducing and blind flanges
- Sight flow indicators and instrument tees; jacketing on most parts
- Process equipment: reactors, receivers and storage vessels to 6,500 gal, columns to 72", shell-and-tube heat exchangers, condensers and Nutsche filters; blue or white glass
Services
- Custom PTFE machining
- Fluoropolymer powder coating
- Reglassing of glass-lined equipment. Most glass-lined items can be reglassed, depending on the damage, with repairs to the shell or nozzles made to the applicable vessel codes. The result is comparable to new at roughly 65% of the cost, with no re-engineering since the equipment design does not change.
- Automated valve packages, built and shop tested in house: any brand of quarter-turn valve with any combination of actuator, solenoid and positioner
