Nickel Alloy Loose Type Flange High Pressure Rating LJRF Lap Joint Flanges for Offshore Field

Lap Joint Flanges LJRF Nickel Alloy Loose Flanges for High Pressure Rating Offshore Field

This type of connection is used for piping in high-cost raw materials like as stainless steel and nickel alloy as it helps to reduce the overall cost of the needed flange connections. A lap joint connection is made by the combination of a stub end (which is the part welded to the pipe) and a backing flange, or lapped flange.

Lap Joint pipe flanges are used with Stub ends to make the flange connections in pipeline systems. These come in ½” to 24” sizes, in 150# , 300#, 400#, 600#,etc pressure class. A stainless steel stub end can be for example used in combination with a carbon steel lap joint flange to have a dependable welded connection at a cheaper cost than a full stainless steel connection (less stainless steel is needed, hence the cost is lower). Lap joint flanges have generally a raised face flange and are sealed with flat ring gasket.
