With the expansion of businesses as well as increasing the population, many of the ways of city transmission services have been taken under ground.
For example, for liquid transfer, underground transmission channels are used .
One of the ways to transport services underground is manhole pipes.
For may have seen manhole valves in streets.
Composite science is producing manhole and composite manhole valve within advancement of industries and technologies.
The composite manhole has certain characteristics which had made the product able to compete well with its metal rivals.
The electricity conductor ability is one of the certain and important advantages so composite manhole covers can be used in sensitive electrical connection industries and places, such as oil and Gas Companies.
Other characteristics of the composite manhole is transferring different fluids .For example, acid cannot be transferred through metal manholes but the composite manhole can transmit acids.
High pressures and heavy weights of the fluids handling is another feature of composite manhole door.
Composite manhole can be produced with a composite manhole valve.
The positive points of these manholes are that the appropriate manhole valve can also be ordered to make the least of failures and problems.
FIBERGS Co. is a leading manufacturer of manhole and manhole composite covers.
Several projects have been conducted in this field.
One of the projects is the manhole project in Tashkent.
The description of project is:
The manhole covers production is diagonal as much as 1200 mm and also a length of 7000 mm.
The main use of this manhole doors is the underground wastewater network which is installed in Tashkent.
The composite manhole valve as well as its frame is also produced for the manhole covers.
