Rubber Expansion Joint Pipe-Design Guide (5 factors considered)
|Direction of Travel Required||straight-line motion|
|Length of Travel Required||small delta between peak and valley of convolutes|
|large delta between peak and valley of convolutes|
|Interface between Rubber Bellows Ends and Mating Components||An extended straight section with a hose clamp|
|A locking grommet securing the bellows into a panel or sheet metal|
|An integrated flange with mounting holes|
|Completely enclosed bellows ends for protecting parts going up and down|
|Outside Constraints||Tapered rubber bellows for tapered mechanisms|
|Straight rubber bellows (cylindrical rubber bellows) for components with external space constraints.|
|Other bellows with different convolutions|
|Working Environment||Important for materials adoption|
Rubber Expansion Joint Pipe-Some Typical Applications:
Rod & Ball screw covers
Piping penetration seals
Fan duct connections
Compressor and engine intake and exhaust manifold connections
Custom Rubber Expansion Joint Pipe Requirements:
1. Offer 2D, 3D design drawings or samples, and also tell us your sizes telorance demands.
2. Bellows Materials Demands: Rubber, Silicone, EPDM, Nitrile, etc, or tell us operating environments, functions etc.
3. Durometer Demands (Hardness Shore A):
4.. Silicone Bellows Surface Demand
5. Working Environmment Demands
6.Silicon Bellows Flashing Demands etc.
(Note: Different Silicone Rubber Bellows durometer demands, surface demands, parting lines demands or rubber flashing demands have different production difficulty and production cost. Epecially for mold-making technology demands, compression mold steel choice, mold maintain when mass production etc.)
