Product Introduction

Lap joint flange is also called looper flange or flanging flange. Lap joint flange belongs to lap joint flange, which is a movable flange with flanging.

The steel ring or stub end in the lap joint flange is the sealing surface, and the function of the flange is to compress them.

Advantages and disadvantages

The advantage of lap joint flange is that the lap joint flange does not contact with the medium and does not produce additional torque to the container or pipeline when the flange is deformed. The flange manufacturer can use materials different from the container or pipeline to save precious metals. The disadvantage is that the loose sleeve ring has low strength and bears low pressure and can not be used in high-pressure pipe network.

Lap joint flange can be divided into three types: flat welded steel ring lap joint flange, plate flanging lap joint flange and butt welded ring lap joint flange.

Lap joint flange is applicable to the connection of non-ferrous metals such as steel and aluminum and stainless acid-resistant steel vessels and corrosion resistant pipelines. Its nominal pressure PN is 1.6MPa.
