Heavy-duty PTFE lined protection rings and covers from 3G are practically everlasting and work as a armour on contact surfaces. Available options include a 3.5mm thick PTFE barrier permanently bonded to steel and a 6mm PTFE encapsulated design.

Advantages

• Economical solution for protecting glass-lined steel manway surface from risk of impact and abrasion
• Prevent Iron contamination.

*Thermal or mechanical shock proof.

• Fitted with welded hinges for easy mounting.
• Prevents glass damage if cover is dropped.
• Can mount to allow cover to hinge from either side.
• Interchangeable with existing protection rings on prominent reactor vessels(DE-DIETRICH/GMM/SWISSGLASS/NILE).
• Metal parts are galvanized and chrome treated for long life.
• Reduces maintenance costs.

Now, you can protect your reactor investment by protecting manway contact surfaces from impact and abrasion with a 3G long life protection ring. The ring is constructed of glassfi lled solid PTFE, the same material used for long life bearings in pumps, seals, and other components. Because PTFE is a resilient material, it withstands impact well. Minor cuts and scratches in the surface will not affect the sealing qualities. Solid glass-fi lled PTFE eliminates the chance of iron contamination even in the event of damage.

Advantages

Protection rings are an economical solution for protecting glass-lined steel manway surface from risk of impact and abrasion with these benefits:

• Dimensionally stable 140 mill thick wear surface – minor gouges will not affect the sealing quality and will not produce iron contamination. Won’t break from thermal or mechanical shock
• Fitted with welded hinges for easy mounting
• Helps prevent glass damage if cover is dropped
• Can mount to allow cover to hinge from either side
• Interchangeable with existing protection rings on 3G and competitor’s equipment
• Popular sizes stocked for fast delivery.
• Metal parts are galvanized and chromate treated for long life.
• Reduces maintenance costs.
