Blind Flange   Lap Joint Flange    Orifice Flange   Slip-On Flange
Socket Weld Flange    Threaded Flange    Weld Neck Flange

Lap Joint Flanges are used with a corresponding stub-end that "inserts" in the inside of the flange.  The main benefit of this type of flange, is that once the pipe welds to the insert stub-end, the flange then can rotate for easier alignment of the bolting holes.  However, lap joint flanges and their stub-ends' ability to hold pressure is about the same as slip-on flanges.  They are not suitable for situations with a high external or changing loads of force.  They do provide an advantage in a piping system that needs frequent dismantling for inspection or to remove build-ups.  If high pressure applications are being performed, either a swivel ring flange or an insert flange, is recommended to be used instead of a lap joint flange an stub-end.  We can provide swivel ring flanges or insert flanges upon your request. 

Key Features:

• Used with a matching stub-end insert
• Recommended in applications that require frequent dismantling of the flanges and pipe
• Lap joint flange can rotate to allow for an easy alignment of bolt holes
• Not recommended in extreme pressure temperature applications
