FAQs
Q1: What is a Lapped Joint Flange?
A Lapped Joint Flange is a two-piece assembly used with a stub end. The flange itself does not contact the fluid medium, which makes it reusable and ideal for systems requiring frequent maintenance.
Q2: How is a Lapped Joint Flange different from other flange types?
Unlike welding neck or slip-on flanges, the lap joint flange rotates around the pipe, making bolt alignment easier. It’s especially useful in confined spaces or systems that require regular disassembly.
Q3: What are the standard sizes and pressure ratings available?
We offer sizes from ½” to 48″ and pressure ratings from Class 150 to Class 2500. PN ratings range from PN6 to PN64.
Q4: What materials are used in manufacturing?
We manufacture lapped joint flanges in carbon steel, stainless steel (304, 316, etc.), alloy steel (F5, F9, F11, F22, etc.), and special alloys such as duplex, monel, Inconel, Hastelloy, and copper-nickel.
Q5: Are custom flanges available?
Yes. We can manufacture custom flanges based on your specifications, including special dimensions, face types, and coatings.
