How to Choose Pipe Fittings
Choosing a pipe fitting requires more than matching the nominal size. The connection, material, pressure, temperature, medium, applicable code and installation layout must all be reviewed together.
Five-step selection method
- Define the connection: choose butt weld, socket weld, threaded, flanged or another approved connection.
- Match dimensions: confirm nominal size, outside diameter, schedule, radius, length and orientation.
- Select material: consider corrosion, temperature, pressure, fabrication and corrosion allowance.
- Check the standard: use the governing ASME, ASTM, DIN, JIS, GB or project specification.
- Confirm quality and delivery: agree inspection, certificates, marking, packaging, quantity and destination.
Comparison questions
For a final selection, compare total service suitability, pressure loss, available space, welding requirements, maintenance access and lifecycle cost—not only unit price.
FAQ
What should I send for a recommendation?
Send the line size, schedule, medium, operating pressure and temperature, material requirement, standard, quantity, drawing and destination.
Request a quotation
Send the product type, nominal size, wall thickness or schedule, material grade, standard, quantity, operating conditions and destination. Drawings and inspection requirements help confirm the correct manufacturing route.
