GT-type Joint Ductile Iron Pipe

The GT-type joint ductile iron pipe adopts an enhanced gasket structure with a lip-shaped sealing tail. Its sealing principle is similar to the T-type joint, but with superior pressure-responsive performance. As the internal pressure increases, the lip section of the gasket is pressed more tightly against the socket surface, resulting in a stronger and more reliable sealing effect.

Key Features

• Lip-shaped gasket design providing pressure-enhanced sealing

• The higher the internal pressure, the tighter the sealing interface

• Suitable for high-pressure and pressure-fluctuating water pipelines

• Simple installation, similar to the T-type joint

• Allows angular deflection to accommodate ground settlement
