Polyethylene manhole

we produces polyethylene manholes in two sizes. In two inner diameters, 1000 is 1200 mm.

The height of these manholes can be adjusted as desired.
The required length can be reached by adding or subtracting intermediate parts. 

The annular resistance of these manholes is proportional to the production pipes. (31.5 KN )

These manholes are composed of upper, middle and lower parts. An o-ring is installed between each piece relative to the other piece, which seals them due to the vertical pressure of the pieces on each other and prevents the exit or entry of various fluids.

Specifications our production manholes: 

	Upper piece: The entrance in both sizes 1000 and 1200 is equal to 60 cm. The height of the upper part of 1000 equal to 80 cm. The height of the upper part of 1200 is equal to 90 cm.
	Middle piece: The height of the middle piece in both 1000 and 1200 sizes is equal to 50 cm Manhole stairs in both sizes of lockable steel are very strong and stainless.
	Bottom piece: Bottom pieces are produced in both 1000 and 1200 sizes in three heights of 45, 60 and 70 cm. Supports size 1000 inputs and outputs from all four sides up to size 315 pipe. Supports 1200 size inputs and outputs from all four sides up to 400 pipes.
