Pipeline wells are intended for the installation to oil lines in order to accommodate instruments, automation devices, add tie-ins or air escapes and protect from unauthorized access to all of the above.
The manholes we make are sized for DN 150, 200, 250, 300, 350, 400, 500, 600, 700, 800, 1000, 1050 and 1200 piping and come in seismic-proof design C (i.e. for regions with seismicity up to 9 inclusive on MSK-64 scale). Climatic design and installation category per GOST 15150-69 are: UKhL1, i.e. for operation in temperature ranges from minus 60°С to plus 40°С.
All manholes have corrosion-proof coating applied in house. Type of coating is tailored to the operation condition.
