Pressure vessels are common in petrochemical, power, and light industries. Types include flat welding, long-neck butt-welding and forged tube sheets and baffle plates.

Lap Joint Flanges

lap joint flanges are designed to slide over pipes, commonly used with stub end fittings. This allows for easy rotation and alignment of bolt holes, making them ideal for applications requiring frequent disassembly.

The taller hubs can be customized based on your requirements.
