Pipe and piping fittings
Ductile iron pipe
Transporting fluid or connecting process components within a pressure boundary
Specialist selection guide
What should be reviewed before selecting this product?
Ductile iron pipe belongs to the Industrial pipes 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 nominal and outside diameter from the project specification and verify it against the manufacturer proposal
- 2
Extract schedule and wall from the project specification and verify it against the manufacturer proposal
- 3
Extract manufacturing route from the project specification and verify it against the manufacturer proposal
- 4
Extract material and grade from the project specification and verify it against the manufacturer proposal
- 5
Extract corrosion allowance from the project specification and verify it against the manufacturer proposal
- 6
Extract documentation and testing from the project specification and verify it against the manufacturer proposal
Key strengths
- Selection within the established Industrial pipes 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 Ductile iron pipe?
At minimum provide nominal and outside diameter, schedule and wall, manufacturing route, material and grade, corrosion allowance and fluid conditions. Final documentation requirements follow the project specification.
Are two Ductile iron pipe products with the same name interchangeable?
No. Installation dimensions, pressure-temperature rating, wetted materials, connection, test method and material certification must be checked independently.
