Frequently asked questions
What is the difference between buttweld and forged fittings?
Buttweld fittings (ASME B16.9) are welded directly to the pipe and used for larger sizes (1/2" and above). Forged fittings (ASME B16.11) use socket-weld or threaded connections and are typically used for smaller sizes (up to 4") and branch connections. Both serve the same purpose - connecting pipe runs - but the joining method and size range differ.
Do pipe fittings come with test certificates?
Yes, all our pipe fittings are supplied with Mill Test Certificates (MTC) stating chemical composition, mechanical properties, and dimensional inspection results per the applicable ASTM standard.
Can you supply fittings to match specific pipe schedules?
Absolutely. Buttweld fittings are manufactured to match standard pipe schedules (Sch 40, 80, 160, XXS). We ensure the fitting wall thickness matches your piping specification to maintain system integrity.
