Manufacturer profiles associated with Hinge Assembly.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The reference operating pressure range is 1.0–1.6 MPa. However, the actual allowable pressure depends on the specific model and application, so you must verify with the manufacturer or supplier.
Materials on file include stainless steel (e.g., 304, 316), carbon steel, and alloy steel. The material grade may be 304/316L (ASTM A240), but confirm the appropriate grade for your media and environment.
The hinge assembly ensures proper alignment of the manway door when closed, allowing the sealing surfaces to mate correctly. The sealing class is Rate 1, meaning no visible leakage, but this depends on correct installation and maintenance.
The reference cycle life is 10,000–50,000 cycles, depending on maintenance. Regular inspection and lubrication of pins and bushings can extend service life. Always follow the manufacturer's maintenance guidelines.
