Industrial Pipe Flanges Manufacturer, Supplier & Exporter
Kemlite Piping Solution manufactures and exports industrial piping flanges — blind (BLRF), socket weld (SWRF), weld neck (WNRF), and slip-on (SORF) designs — engineered for pressure piping applications to ASME B16.5 and ASME B16.47 design standards. We supply flanges in carbon steel, low-temperature steel, stainless steel (SS 304, 316, 321, 347), duplex 2205, super duplex 2507, and nickel alloys including Monel, Inconel, and Hastelloy. Flanges are typically the highest-volume item in any piping export order, and getting the facing, pressure class, and bolt-hole pattern right the first time matters for project timelines. Our team works from your P&ID or material requisition to confirm the correct combination of type, class (150# through 2500#, or PN10 to PN420), and material before quoting, so there are no surprises at inspection. Every flange we ship is backed by ISO 9001:2008 certified manufacturing, EN10204 3.1 material certificates, and third-party inspection on request. Kemlite exports flanges to oil & gas, petrochemical, power, and marine buyers across the Middle East, Africa, Europe, and Southeast Asia.

Frequently Asked Questions
What flange standards does Kemlite work to?
ASME B16.5 for flanges up to 24" NB and ASME B16.47 for larger diameters — confirm your exact class and facing requirement with our team.
What's the difference between weld neck and slip-on flanges?
Weld neck flanges have a tapered hub butt-welded to the pipe for high-pressure integrity; slip-on flanges slip over the pipe and are fillet welded inside and out, suitable for moderate-pressure lines. Ask our team which fits your spec.
Can flanges be supplied with RTJ facing for high-pressure service?
Yes, Ring Type Joint (RTJ) facing is available across all pressure classes from 300# up to 2500#.
