FLANGE GASKET SOLUTION
Selecting Flange Gaskets
Assistance with Leak Issues
Please provide the flange specifications, medium, temperature, pressure, and on-site conditions, and Chengxin will assist in determining the dimensions, materials, and gasket orientation.
COMMON FAILURE CONDITIONS
If the specifications are correct, why is there still a leak?
Dimensions are only one of the factors affecting sealing performance. To understand in-service failures, it is usually necessary to consider the material, operating conditions, flange surfaces, and tightening conditions together.
Repeated Leaks
If leakage persists even after replacing the gasket, it is necessary to inspect the flange surface, the tightening procedure, and changes in operating conditions.
Gasket Deformation
Compression, cold flow, thermal cycling, or fastening conditions may cause the gasket to lose its stable sealing force.
Material Incompatibility
The medium may cause swelling, embrittlement, corrosion, or a decrease in strength; therefore, the suitability of the material must be verified.
High Temperature and High Pressure
Changes in temperature, pressure, and circulation affect material selection, compression recovery, and gasket design.
Uneven fastening
Inconsistencies in bolt sequence, torque, and clamping distribution can easily create localized leakage paths.
Damage to the Flange Face
Scratches, corrosion, warping, and surface condition can affect the contact surface and sealing performance.
HOW WE HELP
Developing Feasible Solutions Based on the On-Site Situation
First, confirm the requirements, then narrow down the options for materials, structure, and processing methods to reduce back-and-forth communication between procurement and engineering.
Provide on-site information
Photos, old parts, drawings, equipment models, or known dimensions are all acceptable.
Compile Failure Conditions
Verify the medium, temperature, pressure, operating conditions, and leakage status.
Narrow Down the Selection Criteria
Organize materials, gasket structures, and size and thickness options.
Confirm Production Requirements
Further confirmation is required based on quantity, documentation, processing methods, and delivery schedule.
GASKET STRUCTURES
Determine the gasket material and structure based on operating conditions
Start by narrowing down the options based on common criteria; the final selection should be based on the medium, temperature, pressure, flanges, and fastening requirements.
Non-asbestos gaskets
Commonly used in water, oil, air, and general industrial piping systems; material selection must be based on the medium and temperature and pressure conditions.
Graphite Gasket
Commonly found in environments involving steam, high temperatures, and thermal cycling; it is necessary to verify the oxidation environment and clamping conditions.
Metal Wrap Spacer
Commonly used in high-pressure, high-temperature, and critical flange connections; it is necessary to verify the pressure rating, inner and outer rings, and gasket material.
