NINGHAO Machinery presents the 4 Inch DN100 Single Ball General Rubber Expansion Joint. This product is designed for use in pipe systems. It supports controlled movement and meets standard requirements.
The joint has a nominal size of 4 inches and a DN of 100 mm. Its overall length is 150 mm, and the diameter is 220 mm. The external diameter is 180 mm. It features a reinforcement of 8×18.
The joint allows 12 mm axial elongation and 20 mm axial compression. It permits 16 mm transverse movement. It achieves an angular deflection of 15°.
The Pressure–Temperature section defines the safe and operable pressure range for the expansion joint. It shows temperature limits and the corresponding pressure values. The chart guides operation under varying conditions. The grey area marks the safe pressure zone. Below are its main aspects and uses.
Horizontal Axis (Temperature) and Vertical Axis (Pressure):
The horizontal axis covers -40°C to 120°C. The vertical axis spans from near 0 MPa to about 1.5–2.0 MPa. These ranges show the operating limits under different temperatures.
Grey Area (Operating or Phase Change Range):
The grey area marks the allowable pressure or stable phase range. Pressures within this zone are safe. Exceeding this range may lead to non-design conditions or safety risks.
Phase Change or Operating Boundaries:
The grey area may indicate the liquid-gas transition. It sets the maximum working pressure. Exceeding these values can cause material or seal failure.
Engineering Application and Safety Design:
The chart aids in selecting proper temperature and pressure conditions. It supports equipment selection, risk assessment, and safety design. It indicates when special materials or devices are required.
