For piping systems that need easier bolt alignment and straightforward disassembly, stainless steel lap joint flanges offer a useful connection arrangement when paired with a suitable stub end. The flange sits over the stub end and can rotate around it, making bolt-hole alignment easier during installation and allowing the flange to be removed without cutting the pipe connection. We source these flanges in SS304/304L and SS316/316L grades for process piping, chemical service, water systems, and other industrial applications. This is why we’re the preffered stainless steel lap joint flanges supplier in Libya.

Key Features

• Rotating flange design helps simplify bolt-hole alignment during piping assembly.
• Works with stub ends to create a bolted connection that can be opened for inspection or maintenance.
• Stainless steel construction is suited to applications where corrosion resistance is an important consideration.

FAQs

1. What is a stainless steel lap joint flange used for?
It is used with a stub end to create a detachable flanged connection in piping systems where easier alignment and future disassembly are useful.

2. Does a lap joint flange need to be welded directly to the pipe?
No. The flange itself sits loosely around the stub end. The stub end is welded to the pipe, while the flange is secured through bolting to the mating flange.

3. Why can lap joint flanges rotate during installation?
The flange is not fixed directly to the pipe, allowing it to rotate around the stub end. This makes it easier to line up bolt holes with the connecting flange.

4. What stainless steel grades are available for these flanges?
Our range includes SS304/304L and SS316/316L grades for different piping and service requirements.

5. What should I check when selecting a lap joint flange?
Check the pipe size, matching stub end dimensions, pressure specification, flange compatibility, and required stainless steel grade before ordering.
