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 for a full-penetration weld and better stress distribution, ideal for high-pressure and cyclic service; slip-on flanges are easier to align and cost less, suited to lower-pressure applications. Ask our team which fits your project.
Can Kemlite supply flanges in duplex or super duplex steel for offshore projects?
Yes, duplex 2205 and super duplex 2507 flanges are available, commonly specified for offshore and subsea piping.
