Corrosion Resistant Roller Chain in United States
Corrosion Resistant Roller Chain in United States
The U.S. EPA WIFIA program continues to provide ongoing credit assistance for drinking-water, wastewater and stormwater projects. This supports a broad market for durable drives used in screens, pumps, conveyors and auxiliary treatment equipment.
Selection priorities in United States
Use the exact EP model and sample dimensions to check the existing sprocket. Review rain, salt, humidity, fertilizer, wastewater splash, cleaning chemicals, dust, seasonal storage and lubricant washout. Dacromet-plated chain is the sample option for corrosive conditions; nickel-plated chain is identified for outdoor rain exposure; zinc-plated chain is the corrosion-resistant plated family.
| Field | Meaning | How it is used |
|---|---|---|
| P | Pitch | Primary chain and sprocket size reference |
| d1 | Roller diameter; external bush diameter on marked bush chains | Confirms roller-seat and sprocket compatibility |
| b1 | Width between inner plates | Checks sprocket tooth and side-clearance fit |
| d2 | Pin diameter | Part of the chain construction reference |
| L / Lc | Maximum pin lengths | Checks overall width and connecting-link clearance |
| h2 | Inner plate depth | Used for envelope and guarding checks |
| t/T | Plate thickness | Construction and side-clearance reference |
| Q | Breaking load | Not a working-load rating; selection still requires duty data |
| q | Weight per meter | Useful for handling and drive-system calculations |
