Where are Lap Joint Flanges commonly used?
Lap joint flanges are generally employed in piping systems that are subject to frequent disassembly for inspection or cleaning. They are most suitable for applications with space limitations or requiring frequent access, such as chemical plants and water treatment facilities.
Are Lap Joint Flanges suitable for high-pressure systems?
No, lap joint flanges are usually suitable for low-pressure, non-critical services. Loose design does not accommodate high-stress sealing and thus such flanges are not appropriate for pressure-loaded systems. They are, however, very flexible for maintenance and are good for corrosive conditions with the use of corrosion-resistant stub ends.
Can Lap Joint Flanges be customized?
Yes, lap joint flanges can be customized in terms of material, size, face type and bore dimensions. We offer manufacturing based on ASME, DIN and EN standards to suit project-specific requirements. Customization ensures compatibility with piping configurations, gasket types and environmental needs.
