Fasteners for Pressure Vessel Applications
Fasteners for Critical Pressure Vessel Connections
Vessel Flange Connections
Flange fasteners provide the required clamping connection between pressure vessel flanges and associated piping or equipment.
Pressure Vessel Head & Cover Connections
Head and cover fasteners secure removable pressure-containing components while maintaining the required bolted joint configuration.
Manway Connections
Manway connections require properly specified bolts or studs to maintain reliable closure and facilitate future maintenance access.
Nozzle & Piping Connections
Fasteners for vessel nozzles and piping connections must be selected according to the connection design, operating conditions and material requirements.
Pressure-Containing Assemblies
Bolting used in pressure-containing assemblies must be manufactured and inspected according to the applicable project requirements.
High-Pressure Bolted Connections
High-pressure applications require fasteners capable of maintaining appropriate mechanical performance and clamping loads under demanding conditions.
Bolted Joint Integrity
Proper fastener selection, dimensional accuracy, material compatibility and controlled installation all contribute to reliable bolted joint performance.
Pressure Vessel Fasteners for Demanding Service Conditions
High-Pressure Applications
Pressure vessel fasteners can be manufactured from materials and grades selected for high-pressure service requirements.
High-Temperature Applications
For elevated-temperature service, material selection and mechanical properties must be considered carefully to maintain reliable fastener performance.
Pressure & Load Considerations
Fastener dimensions, grade and configuration can be selected according to the loads and connection requirements specified for the equipment.
Thermal Cycling
Repeated heating and cooling can influence bolted joint behavior. Appropriate material and fastener selection helps support reliable connections during thermal cycling.
Corrosion Considerations
Fastener materials and surface finishes can be selected based on the surrounding environment and expected corrosion exposure.
Chemical & Process Fluid Exposure
Chemical and process environments can require specialized corrosion-resistant materials and protective finishes.
