Flexible Rubber Joint with Full Face Flange Gasket
High Pressure Expansion Joint

Flexible Rubber Joint With Full Face Flange Gasket Also Called High Pressure Expansion Joint, Is A Rubber Joint With A Full Face Flange Gasket That Is Integrated With The Rubber Ball, Which Has The Advantage Of Being Able To Withstand High Pressure And Prevent Pull-Off Etc

With limit bolt

Without limit bolt

Specification

Design

Full Face Flange Gasket And The Ball Of Expansion Joint Is All-In-One Design，Then Ensure That The Rubber Joints Will Not Be Pulled Off

Use

Suitable For Sealing Requirements Of Strict, High Pressure Projects

For Large Diameter Rubber Joints, We Recommend Use End Face Fully Sealed Rubber Joints, So That They Can Be Safer And Last Longer During Use.

Advantage

High Pressure Resistance, Good Elasticity, Large Deflection Displacement, Aging Resistance, Vibration And Noise Reduction Etc

Suitable For The Following Media:

Seawater, Fresh Water, Hot And Cold Water, Drinking Water, Domestic Sewage, Crude Oil, Fuel Oil, Lubricating Oil, Refined Oil, Air, Gas, Steam And Granular Powder.

What is the difference between normal rubber expansion joint and the one with full face flange gasket?

If The Pipeline Pressure Is Less Than 1.6MP, The Normal Rubber Expansion Joint Can Work Well, If The Pipeline Pressure Is More Than 1.6MP, You Have To Use Flexible Rubber Joint With Full Face Flange Gasket, The Difference Between The Normal Rubber Expansion Joint And The One With Full Face Flange Gasket Is That The Normal Rubber Expansion Joint Uses A Slotted Flange, Flexible Rubber Joint With Full Face Flange Gasket Uses A Flat Welding Flange. In Addition, Flexible Rubber Joint With Full Face Flange Gasket Sides Are The Same Size As The Outer Edge Of The Flange, The Flange And The Edge Of The Sphere Are Installed Together Inside When The Bolt Is Installed, Which Greatly Increases The Pressure Resistance Strength, Generally Can Reach 2.5MP Or 4.0MP Pressure. When The Pressure Is Too Large, The Sphere Is Required To Be Configured With A Pressure-Boosting Ring Outside, And The Flange Ends Are Configured With A Limit Device To Prevent The Pipeline Pressure From Rising To Produce Over-Limited Radial Displacement, Thus Playing A Protective Role.
