Non-Metallic Expansion Joints are designed for tough, demanding industrial applications, as found in: Chemical/Petrochemical Plants, Industrial Process Piping Systems, Marine Services, Power Generation Plants, Pulp/ Paper Plants, Steel Mills, Water/Wastewater and Pollution Control Systems. Installed next to mechanical equipment or between the anchor points of a piping system.

(1) Absorb Pipe Movement/Stress,

(2) Reduce System Noise,

(3) Isolate Mechanical Vibration,

(4) Compensate Alignment/Offset,

(5) Eliminate Electrolysis,

(6) Protect Against Start-Up Surge Forces. Our history in the manufacture of expansion joints dates back to l930. When you need an engineered rubber expansion joint solution to a piping problem, call Liwei.

This new hand-built product has been completely re-engineered to provide improved strength, flexibility, movement and spring rate capabilities. Manufactured utilizing tire industry technology, the Liwei brand combines woven nylon fabric and nylon tire cord into a fabric matrix bonded with elastomer and reinforced with wire to create a product with greater operating performance. The nomenclature for the new Liwei.

Greater Movements With A Lower/Wider Arch Profile. The movements for the Liwei Series brand exceed the specification of the Fluid Sealing Association's Rubber Expansion Joint Division Technical Handbook (Sixth Edition), Table V. Due to a new and improved lower, wider profile arch, more axial compression and axial extension coupled with lateral misalignment, angular and torsional movements can be obtained without increasing the face-to-face requirements. Installation of the Series Liwei brand in a piping system will negate the need for long and expensive multi-arch products. For greater movements based on reengineering and new product construction, specify Liwei brand.

Less Turbulence Or Material Entrapment. The Liwei brand Series molded integral flange joins the body at a true 90° angle. Our product will install snug against the mating pipe flange without voids. The flange body of the rubber expansion joint is difficult to form and many manufacturers radius the edge angles. The resulting void between the mating flange and the edge angle can create flow turbulence and allow for material entrapment or bacterial growth. You can avoid these problems by specifying Liwei rubber expansion joints.
