Irregular Flanges, Also Known As Sealing And Fastening Connectors, Are Disc-shaped Parts That Are Most Commonly Used In Pipeline Engineering. Flanges Are Also Used In Pairs. In Pipeline Engineering, Flanges Are Mainly Used For Pipeline Connections. Install Flanges In Various Ways In The Pipelines That Need To Be Connected. Low Pressure Pipelines Can Use Threaded Flanges, And Welded Flanges Can Be Used When The Pressure Is Above 4 Kg. Add Sealing Points Between Two Flanges And Tighten Them With Bolts. Flanges With Different Pressures Also Have Different Thicknesses And Use Different Bolts. The Parts Of These Devices Are Also Made Into Corresponding Flange Shapes, Also Known As Flange Connections. It Is Widely Used In Large Containers In Aerospace, Petroleum, Chemical And Other Fields.

1、 Advantages Of Alien Flanges

Compact Shaped Flanges Have Multiple Advantages: Standard Shaped Flanges Not Only Save Space And Reduce Weight, But More Importantly, They Ensure That There Is No Leakage At The Joint. The Reason For The Reduction In Size Of The Compact Flange Is The Decrease In The Diameter Of The Seal, Which Will Reduce The Cross-section Of The Sealing Surface. Secondly, The Flange Gasket Has Been Replaced By A Sealing Ring To Ensure That The Sealing Surface Matches The Sealing Surface. In This Way, Only A Small Amount Of Pressure Is Needed To Tightly Compress The Lid. As The Required Pressure Decreases, The Required Bolt Size And Quantity Can Correspondingly Decrease.

2、 Classification Of Alien Flanges

The Structure Of The Special-shaped Flange Varies Depending On The Type Of Oil Pipe Hanger Selected. The Irregular Flange Is A Transitional Connection Between The Tubing Head And The Christmas Tree.

The S-shaped Flange Is Used In Conjunction With S-type And S-I Type Oil Pipe Suspensions. The Lower Flange Is Bolted And The Upper Flange Is Threaded. Flanges Can Be Equipped With Or Without Hydraulic Control Pipeline Holes According To User Needs, And The Pipeline Suspension Is The Same. Connect The Threaded NPT1/2 To The Irregular Flange.

The Lower Part Of The T-shaped Flange Is Connected By Bolts, While The Upper Part Can Be Connected By Bolts Or Threaded Connections. Use Oil Pipe Threads To Process The Lower Hole. Usually Used Together With S-II Tubing Suspension, It Can Also Be Directly Suspended With Tubing. WA Type Wrapped Oil Pipe Suspension Should Be Installed.

MH Type Irregular Flange Is Used In Conjunction With MH Type Oil Pipe Suspension. The Lower Part Is Connected By Bolts, And The Upper Part Is Connected By Threading. There Are Special High-strength Trapezoidal Threads Processed Internally To Connect And Seal MH Type Oil Pipe Suspensions.

How To Process Irregular Flanges?

Due To The Difference Between The Nominal Diameter Of The Container Cylinder With Irregular Flanges And The Specific Size Represented By The Nominal Diameter Of The Pipeline, The Dimensions Of Container Flanges And Pipeline Flanges With The Same Nominal Diameter Are Also Different, And The Two Cannot Be Used Interchangeably.

Usually, Irregular Flanges Are Processed In Several Arc Segments. Firstly, Forge The Blank Into A Square Billet, And Then Cold Form It Into An Arc Shape. After Annealing And Stress Relieving Heat Treatment, It Is Assembled Into A Complete Circle And Machined Into The Designed Shape And Size On A Vertical Lathe. Finally, Transport It To The Construction Site And Combine Several Arcs Together. Weld Into A Complete Irregular Flange And Then Assemble It With The Pressure Vessel.

Irregular Flanges Have Different Production Standards In Use And Production. According To The Corresponding Standards, It Can Ensure The Practical Value And Function Of The Special-shaped Flange.
