Starting From 49Rs/Pcs

SS 316 Lap Joint Flanges Available in Following Metals & Grades

Our SS 316 Lap Joint Flanges are designed for piping systems requiring frequent dismantling for inspection or cleaning. This two-part assembly consists of a stub end (welded to the pipe) and a loose backing flange that slides over it. As a trusted SS 316 Lap Joint Flanges Manufacturer in Mumbai and Maharashtra, we offer high-quality flanges that simplify bolt alignment by rotating freely around the stub. Made from corrosion-resistant Stainless Steel 316, these flanges are ideal for low-pressure applications in marine and chemical industries. Choose a reliable SS 316 Lap Joint Flanges Supplier in India for durable piping solutions that reduce installation time.

Benefits and Application of SS 316 Lap Joint Flanges

Easy Bolt Hole Alignment: The flange rotates freely around the stub end, allowing for instant bolt hole alignment with the mating flange without rotating the pipe itself. Simplified Maintenance: Because the flange is not welded to the pipe, the connection can be easily dismantled for frequent inspection, cleaning, or replacement of gasket seals. Cost-Effective Assembly: In many setups, only the stub end needs to be high-grade alloy (wetted part); the backing flange does not contact the fluid, though using SS 316 ensures external corrosion resistance.

Some FAQ


What is the difference between a Lap Joint and a Slip-On flange?	A Lap Joint flange is used with a stub end and is not welded to the pipe, whereas a Slip-On flange is welded directly to the pipe (fillet weld).
Do you supply the stub ends along with the SS 316 Lap Joint Flanges?	Yes, as a complete SS 316 Lap Joint Flanges Supplier in Mumbai, we can supply both the backing flange and the matching stub ends.
What is the main advantage of using SS 316 for this flange?	SS 316 contains molybdenum, which provides superior resistance to pitting and crevice corrosion in chloride-rich environments compared to SS 304.
Can the flange rotate after installation?	The flange can rotate around the stub end before the bolts are tightened, which solves misalignment issues during the fit-up process.
What pressure ratings are suitable for Lap Joint Flanges?	They are typically used in lower pressure classes, such as 150# and 300#, but we can manufacture them for higher ratings if specified.
Are you an SS 316 Lap Joint Flanges Manufacturer in India accepting custom orders?	Yes, we manufacture standard ANSI dimensions and can also fabricate custom sizes based on specific client drawings.
Do you provide material certificates with the flanges?	Absolutely. All orders are accompanied by Mill Test Certificates (MTC) per EN 10204 3.1 to guarantee material authenticity.
Is this flange suitable for corrosive fluid lines?	Yes, provided the stub end (which touches the fluid) is made of a compatible corrosion-resistant material like SS 316.
