Buttweld Pipe Fittings Manufacturer, Supplier & Exporter
Kemlite Piping Solution manufactures premium buttweld pipe fittings — elbows (45° and 90°, long and short radius), concentric and eccentric reducers, equal and unequal tees, and stub ends — engineered to ASME B16.9 for critical piping, pressure, and process applications. We supply buttweld fittings in carbon steel, low-temperature carbon steel, alloy steel, stainless steel, duplex, super duplex, titanium, and nickel alloys. Buttweld fittings are welded directly onto pipe ends, so weld-quality control and dimensional accuracy directly affect the integrity of the finished piping system — our fittings pass through the same ISO 9001:2008 QC process as the rest of our range, with full material traceability from raw forging or plate to finished fitting. We manufacture and export buttweld fittings for oil & gas, petrochemical, power generation, water treatment, and HVAC piping systems, with custom non-standard sizes and configurations available for projects that fall outside catalog dimensions. Send us your size (15 NB to 100+ NB), schedule, and material grade for a fast quote.

Frequently Asked Questions
What's the difference between buttweld and socket weld fittings?
Buttweld fittings are welded end-to-end for full penetration and are typically used in larger-bore, higher-pressure lines; socket weld fittings insert the pipe into a socket for a fillet weld, common in smaller-bore lines. Ask our team which suits your spec.
Can Kemlite manufacture custom or non-standard buttweld fitting configurations?
Yes, we manufacture non-standard sizes and configurations to customer drawings and specifications.
What sizes and schedules are available?
From 15 NB up to 100+ NB, in standard and custom wall thickness/schedule — confirm your exact range with our team.
