Non-metallic Expansion Joint
AP Connector is a non-metallic expansion joint used for the expansion part of bellows employing cloth and resin materials.
It combines the elasticity of nonmetal with a free range of materials to produce a variety of results, and can insulate duct piping against displacement, vibration, and/or stress.
- Used with cloth or resin in flexible areas to absorb complex displacement and ensure superior flex resistance
- Handles corrosive exhaust gas resulting from usage of PTFE film
- Shows greater absorption of displacement than metal expansion joints, reducing the number required in individual (single) equipment lines, allowing narrower installation widths (interface)
- As the basic component is cloth or resin, less reaction occurs in the equipment line, easing duct layout including supporting positions of duct.
- Available in any shape, such as round, square, and atypical, with large bore
- Exhaust gas systems in boilers and gas turbines
- Ventilator systems
- A wide variety of smoke and exhaust gas systems
- Openings or duct systems of flue gas desulfurization and denitrator equipment
- Air-exhaust ventilator and dust collector openings
- Expansion joints absorb expansion and contraction of ducts and peripheral equipment, easily allowing the load to be concentrated; however, as deterioration occurs over time, they must be changed regularly.
- A&AM conducts the following maintenance inspections:
- 1)Visual exterior checks, palpation, noise checks (in operation and under suspension)
- 2)Surface temperature observation via infrared camera (in operation)
- 3)Inspection of internal heat-insulating materials via borescope (under suspension)
- 4)Sampling analysis
- 5)Other (wall thickness inspection of fluid contact metals, etc.)
- Timely repair / replacement of parts showing deterioration prevents any damage from progressing to a serious stage.
- Please inquire with any further questions concerning maintenance.
- Further information on handling precautions and safety issues is contained in the safety data sheet (SDS) of each respective material.
