Product Description
Product Overview
The B2F DN500 Double Flange Limited Dismantling Coupling is a critical pipeline connection component designed for industrial applications. This carbon steel fitting allows free expansion and contraction within specified limits while providing secure connection and protection against excessive displacement.
Structural Components
Key Elements:
- Body: Withstands pipeline pressure and thrust forces
- Sealing Ring: NBR nitrile rubber construction prevents leakage with superior sealing performance
- Gland: Secures sealing ring position to maintain integrity
- Limiting Screw: Prevents damage by restricting maximum expansion/contraction
- Limit Expansion Pipe: Accommodates pipeline movement within safe parameters
- Nuts & Bolts: Provide secure fastening and adjustment capabilities
