LXHTR PP Plastic Flange Guards are manufactured from injection-molded polypropylene to provide an economical and reliable solution for containing accidental chemical spray-outs from pipe flange connections. Lightweight, corrosion-resistant and easy to install, they help improve workplace safety while protecting personnel and nearby equipment.

Industrial flange leaks can unexpectedly release hazardous liquids under pressure, creating safety risks for personnel and surrounding equipment.
Unlike flexible fabric-style flange guards, LXHTR PP Plastic Flange Guards are manufactured from rigid injection-molded polypropylene, providing a durable, lightweight and economical solution for everyday industrial splash protection. Designed to help contain accidental spray-outs while allowing quick visual leak identification, they are widely used across chemical plants, water treatment facilities, mining operations and general industrial piping systems.

1. Are PP Plastic Flange Guards intended as permanent corrosion protection?
No. PP Plastic Flange Guards are designed as a secondary splash protection device to help contain accidental chemical spray-outs caused by flange leaks. Their primary purpose is to:
Help protect nearby personnel from hazardous liquid spray
Reduce contamination of surrounding equipment
Allow leaks to be detected quickly during routine inspections
They are not intended to provide permanent corrosion protection or withstand continuous exposure to leaking chemicals. Once a leak is detected, the piping system should be inspected and repaired as soon as possible.
2. What chemicals are PP Plastic Flange Guards suitable for?
Polypropylene provides good resistance to most acids, alkalis and many industrial chemicals used in standard processing environments. For highly aggressive chemicals or higher operating temperatures, PTFE Flange Guards are recommended.
3. Are PP Plastic Flange Guards pressure-retaining devices?
No. They are designed only to contain accidental spray-outs from leaking flange joints and are not intended to seal or withstand pipeline pressure.
4. What is the difference between PP Plastic Flange Guards and PP Fabric Flange Guards?
PP Plastic Flange Guards are manufactured from rigid injection-molded polypropylene, providing excellent durability, dimensional stability and cost-effective splash protection.
PP Fabric Flange Guards are manufactured from woven polypropylene fabric, offering greater flexibility for irregular piping layouts while maintaining good chemical resistance.
