Best 10 stub ends Factory in the world 2025 - Blog

Introduction to Stub Ends

Stub ends, also known as lap joint stub ends, are pipe fittings that are used in conjunction with lap joint flanges. They are designed to provide a smooth bore and a leak - tight joint. Stub ends consist of a short length of pipe with a flared end. The flared end allows the lap joint flange to slide over it, creating a connection that is easy to assemble and disassemble. This type of fitting is commonly used in applications where frequent maintenance or inspection is required, such as in chemical processing plants, oil and gas refineries, and power generation facilities.
