Lap joint flange orloose flanges for connecting pipes or pipes or fittings
Since lap joint flanges do not require welding and can be quickly assembled and disassembled, they are a time-saving and cost-effective option.
Lap joint flanges are popular with a name called loose flanges. These flanges are appropriate for connecting pipes or pipes or fittings. They are distinct from other flange types because they are not welded directly to the pipe.

Why Choose Our Blind Flanges?
- Reliable Sealing: Effectively seals pipelines, valves, or pressure vessels to block fluid flow, ensuring no leaks and maintaining system integrity.
- High Mechanical Strength: Designed to withstand significant mechanical stress, including system pressure and bolting forces, making it suitable for demanding applications.
- Easy Access: Can be unbolted for straightforward access to the pipeline or pressure vessel, facilitating maintenance, inspection, or use as a manhole.
- Versatile Use: for applications where a permanent or temporary seal is needed, such as in pipelines, pressure vessels, and as manholes.
- Quality and Compliance: Made to meet rigorous standards (GB/T9119-2010, HG/T20592-2009, DIN, ASME, BS, JIS) and available in various high-quality materials like 304, 316L, and high-strength alloys.
