Hand Wrap Rubber Expansion Joint
Hand wrap or Hand build of Rubber Expansion Joint are traditional, hand built, spool type expansion joints that can be customized for a wide range of dimensions, lengths, and heavier materials (available in sizes 1″ through 12″). They are commonly seen in more industrial applications such as mining, power, petrochemical, refining, or for slurry. 1.Absorption of Directional Movement 2.Less Turbulence or Material Entrapment 3.Absorption of Vibration, Noise and Shock 4.Compensation for Misalignment 5.Wide Range of Service and Lighter Weight 6.Easy Material Identification
Description
Description of Hand Wrap Rubber Expansion Joint
Hand Wrap Rubber Expansion Joints are all hand built by our skilled craftsmen. The 1/4” minimum thickness solid elastomer tube is continuous with the flange face. Multiple plies of rubber impregnated high strength polyester or nylon tire cord form the first pressure reinforcement over the tube. Arch swell in response to pressure and arch migration are virtually eliminated by criss-crossed layers of reinforcement that pass over the arch and around steel or ductile iron rings embedded on both sides at the base of the arch. Body swell is controlled by high strength fabric or spiral steel wire. Large diameter joints are often built with steel rings in place of the wire when in addition to internal pressure, external pressure resistance is important. External pressure may come from deep burial, shallow embankment under roadways or joints inside tanks.
Advantage
- Hand-wrapped custom architecture allows design changes while still providing a wide range of bow movements
- Excellent absorption capacity for directional movement
- Double reinforcement structure can extend the life expectancy of joints
- A versatile, reliable and economical solution to meet your pipeline needs
Temperature and pressure
- Suitable for temperatures exceeding 350°F (176°C), depending on service, reinforcement and composite materials
- Support pipeline system pressure range from 85 Psig to 225
