Geothermal Energy

Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth’s surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity. However, for electricity, generation high or medium temperature resources are needed, which are usually located close to tectonically active regions.

IMPORTANCE

Geothermal power is based on heat energy stored underneath the ground. This intense heat is trapped in enormous quantities inside water reservoirs in the earth’s crust. In fact, it is considered essentially limitless.

One common feature of most of power generation systems is to convert heat to electricity. In geothermal power plants, heat is provided by Earth (Geo) Energy is accessed by drilling water or steam wells by very similar method used for drilling for crude oil. Geothermal power plants have similar components which are already used for traditional power generation systems likewise turbines, generators, transformers and other equipment.

WHAT WE DO FOR GEOTHERMAL POWER PLANTS

Ayvaz uses its extensive experience in producing expansion joints for Geothermal power generation piping systems with a remarkably impressive reference list.

Pressure Balanced Expansion Joints
• Bellows design for Isopentane vapour
• High pressure&full vacuum
• Combined axial and lateral movements

Benefit

A pressure balanced expansion joint is used to accommodate and counteract the bellows pressure thrust. An additional bellows joins to the construction to incorporate into the unit and is subject to the line pressure to generate a force equal and opposite to that on the main bellows. Connecting all these bellows together neutralizes the pressure load on the construction. Pressure balanced expansion joints are generally installed at changes of direction in piping (elbow type) but in-line types are also available. Use of pressure balanced expansion joints help the piping designers not to create main anchors to accommodate combined movements at the direction changing points.

Ayvaz also produces Externally pressurized expansion joints provide the most suitable solution for high axial movement needs for under or over soil geothermal media transporting lines with or without insulation.
