Product Description
Cast Iron Ductile Ball Joint for Water Supply Project
High Pressure 1.6MPa Ductile Iron Flange Expansion Joint (VSSJA-2 Type)
Product Overview
Chemical Pipeline B2f Double Flange Expanded Metal Disassembly Joint
Product Description
The double flange limited expansion joint consists of main components, sealing rings, gland, telescopic short pipe and other essential parts. Building upon the original performance of loose sleeve expansion joints, this design incorporates a limit device with double nut locking at maximum expansion. The pipeline can freely expand within allowable limits, and once exceeding maximum expansion, ensures safe pipeline operation - particularly valuable for vibration-prone or slightly inclined and bending pipeline connections.
Core Functional Roles
- Displacement Compensation and Stress Elimination - Absorbs axial displacement from temperature changes (-30℃ to 350℃) in pipes (up to ±100mm per EJMA IV standard), preventing leakage at flange sealing surfaces
- Vibration Buffering - Mitigates mechanical vibrations from pumps and compressors (≥90% damping efficiency in nuclear applications), protecting sensitive equipment
- Installation Alignment Correction - Spherical seal design allows ±5° angular deflection, compensating for alignment errors during pipe construction
