Joining, flanges and sealing
High-temperature bolting
Joining, sealing or isolating sections of piping
Specialist selection guide
What should be reviewed before selecting this product?
High-temperature bolting belongs to the Stud bolts, bolts and nuts 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 diameter and length from the project specification and verify it against the manufacturer proposal
- 2
Extract thread series from the project specification and verify it against the manufacturer proposal
- 3
Extract bolt grade from the project specification and verify it against the manufacturer proposal
- 4
Extract nut grade from the project specification and verify it against the manufacturer proposal
- 5
Extract coating from the project specification and verify it against the manufacturer proposal
- 6
Extract lubrication and torque from the project specification and verify it against the manufacturer proposal
Key strengths
- Selection within the established Stud bolts, bolts and nuts 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 High-temperature bolting?
At minimum provide diameter and length, thread series, bolt grade, nut grade, coating and fluid conditions. Final documentation requirements follow the project specification.
Are two High-temperature bolting products with the same name interchangeable?
No. Installation dimensions, pressure-temperature rating, wetted materials, connection, test method and material certification must be checked independently.
