Nickle Alloy Steel Flanges Blind Flange RF Monel 400 12" 900# Forged Pipe Fittings

A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term "flange" is also used for a kind of tool used to form flanges.

Blind flange, real name is blind plate. It is a connection form of flange. In fact, it is a flange without a hole in the middle.

One of its functions is to block the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. In terms of sealing effect, it has the same effect as the head and pipe cap. However, there is no way to disassemble the head, and the flange blind plate is fixed with bolts, which is very convenient to disassemble.

The structure of Monel 400 (UNS N04400, NCu30) is a high-strength single-phase solid solution, which is a corrosion resistant alloy with the largest amount, the most widely used and excellent comprehensive performance. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine medium, and also has excellent corrosion resistance to hot concentrated alkali solution. At the same time, it is also resistant to corrosion of neutral solution, water, seawater, atmosphere, organic compounds, etc. An important feature of the alloy is that it generally does not produce stress corrosion cracks and has good machinability.
