Closing a line end or providing positive isolation
Specialist selection guide
What should be reviewed before selecting this product?
Ring-joint blind belongs to the Line blinds and isolation plates family. Technical selection must start from actual service conditions, followed by verification of dimensions, pressure-temperature duty, material, connection, construction standard, testing and manufacturer documentation against the project piping class.
Technical selection path
- 1
Extract size from the project specification and verify it against the manufacturer proposal
- 2
Extract class from the project specification and verify it against the manufacturer proposal
- 3
Extract facing from the project specification and verify it against the manufacturer proposal
- 4
Extract thickness from the project specification and verify it against the manufacturer proposal
- 5
Extract material from the project specification and verify it against the manufacturer proposal
- 6
Extract handle and marking from the project specification and verify it against the manufacturer proposal
Key strengths
- Selection within the established Line blinds and isolation plates family
- Compatibility review across project materials and connections
- Structured technical comparison before final enquiry
Selection limitations
- A trade name or product name alone does not define the technical specification
- Pressure-temperature limits depend on material, design and standard edition
- Substitution requires dimensional, functional and documentation verification
Typical applications
Where can this option be considered?
- Evaluation for Oil and gas projects subject to service-condition approval
- Evaluation for Refining projects subject to service-condition approval
- Evaluation for Petrochemical projects subject to service-condition approval

Common technical questions
Concise answers before enquiry
What information is required to enquire about Ring-joint blind?
At minimum provide size, class, facing, thickness, material and fluid conditions. Final documentation requirements follow the project specification.
Are two Ring-joint blind products with the same name interchangeable?
No. Installation dimensions, pressure-temperature rating, wetted materials, connection, test method and material certification must be checked independently.
