Model CM-2P In-Swing Manways are designed for vertical wall access into new or existing composite wall tanks including polyethylene, polypropylene and fiberglass. Manways come complete with two drilled mounting flange rings to reinforce the composite wall at the manway location and include flange gaskets, manway gasket, adhesives and bolt-up hardware. Detailed Installation Instructions are included.
Typical applications include wastewater treatment plants, liquid storage tanks, secondary containment vessels, water storage tanks and other chemical resistant tanks.
The stress on a poly or fiberglass tank when a hole is cut into the sidewall generally requires an FEA (finite-element-analysis) to determine that the tank stability is not unduly compromised. This engineering aspect of the manway installation should be reviewed by the customer and is not a procedure that Chase calculates.
Average installation time is 3-4 hours. Conforms with OSHA Permit Required Confined Space Rules. Lockout protection is provided.
