About the collection

It is known that the Nobels introduced several innovations in the oil industry, laid the foundations for the construction of oil pipelines and built railways, tank waggons and transhipment tankers. This exhibit is a tap that is attached to the pipeline and ensures the interruption and supply of oil products. The oil pipeline has a shut-off valve and a tap.It is usually made of cast iron or steel because it must withstand chemically active substances and resist corrosion so that the seal does not break and the substance does not leak. Its diameter is determined by the diameter of the pipe to which it is attached. This tap is characterised by reliability, high tightness, convenient operation, and low effort required to  turn it.
