What is Class 1500 Lap Joint Flange
Class 1500 lap joint flange is a connecting element mainly used to join pipes or pipe components together or to secure equipment to a surface. Flanges can typically be round or square and are used in various industrial applications. Lap joint flange has two main components: a flange face and stub end.
A lap joint or overlap joint is a joint in which the members overlap. Lap joints can be used to join metal.
Lap welding joints are essentially a modified version of the butt joint. They are formed when two pieces of metal are placed in an overlapping pattern on top of each other. They are most commonly applied to joint weld two pieces with different thickness. Welds can be made on one or both sides.

Advantage of Lap Joint Flange
Lap joint flanges allow pipes of various materials, diameters, or end types to be joined together using a single flange and stub-end assembly. This versatility makes it easier to modify or expand piping systems without requiring significant rework.
Application
Lap joint flange and stub end assembly are mostly used in pipe systems that necessitate frequent dismantling for inspection or routine maintenance. It is also used in the erection of large diameter or hard-to-adjust piping configurations because of its quick bolt hole alignment.
