Monel Lapped Joint Flanges

Lap flanges slip directly over the pipe and are used with stub end fittings and also swivel complementary to the stub end. This type of flange is required for pipe assemblies where each side of the flange is connected to the stub end and a loose backing flange. The outside diameter of the outer stub end is connected by a removable backing flange which is butt welded to the pipe.

Product Introduction

Monel lap joint flanges are made from a nickel-copper alloy that offers high strength, toughness and excellent corrosion resistance over a wide temperature range. One outstanding feature of Monel lap joint flanges is their excellent resistance to hydrofluoric acid, a particularly difficult acid to handle, up to its boiling point. Monel lap joint flanges are probably the most resistant of all the alloys commonly used for hydrofluoric acid applications.

Nickel Monel Lap Joint Flange

Properties of Monel Lapped Joint Flanges:

  • Best resistance to hydrofluoric acid
  • Best resistance to seawater for marine applications
  • High strength metal with good hardness at elevated temperatures

Advantages of Monel Lap Joint Flange

The lap flange has the ability to rotate around the pipe. It works with the arrangement of bolt holes of contrast flanges. Contact with the fluid inside the pipe does not cause toughness of these ribs. Easy to prepare and can be framed between different metals such as aluminum and copper. Various thicknesses are required (thinner parts should be welded on).
