Pipe Fittings — Elbows, Tees, Reducers
ASME B16.9 buttwelding and B16.11 forged socket-weld / threaded fittings in carbon steel, stainless steel and alloy steel, NPS 1/8″–48″.
Standards & Materials
Buttwelding fittings follow ASME B16.9 (NPS 1/2–48) in carbon steel ASTM A234 WPB (-29°C to 425°C), stainless A403 WP304 / WP316 (up to 538°C) and low-temperature A420 WPL6. Forged fittings follow ASME B16.11 (NPS 1/8–4): threaded ends in Classes 2000 / 3000 / 6000, socket-weld ends in Classes 3000 / 6000 / 9000, in ASTM A105 carbon steel or A182 F304 / F316 stainless.
Every order can be supplied with EN 10204 3.1 mill test certificates, heat-number traceability and third-party inspection (SGS / BV / TUV). Pipe unions, threaded nipples and lap-joint stub ends complete the range for maintenance and OEM applications.

FAQ
What sizes do ASME B16.9 fittings cover?
Factory-made buttwelding fittings from NPS 1/2 through NPS 48, with some types to NPS 60 by agreement.
What pressure classes apply to B16.11 forged fittings?
Threaded-end fittings: Classes 2000, 3000 and 6000. Socket-weld-end fittings: Classes 3000, 6000 and 9000.
Which material should I choose?
A234 WPB carbon steel for general service (-29°C to 425°C), A403 WP304 / WP316 for corrosive or higher-temperature service (up to 538°C), and A420 WPL6 for low-temperature service.
Eccentric or concentric reducer — which one for pump suction?
Use an eccentric reducer with the flat side on top for horizontal pump suction lines, to avoid air pockets; concentric reducers suit vertical lines.
Do you provide mill test certificates?
Yes — EN 10204 3.1 certificates covering chemistry and mechanical properties, with third-party inspection (SGS / BV / TUV) on request.
