Corrosion inhibitor for the preservation internal surfaces

It was suggested a combined corrosion inhibitor N-M-1 (gi) which is a mixture of contact and volatile forms with a common component. The material is the most effective if combined with hydrotest of equipment and conservation. Itmay also be recommended for the temporary protection of pipe's internal surfaces in the factory and field conditions.
Materials and methods
To study the protective capability of the inhibitor was used the method of accelerated corrosiontests simulating the conditions in a sealed container.
Results
1.A corrosion inhibitor N-M-1 is an analogue of M-1 and compatible with various bases conservation compositions. 2. Modification of the N-M-1 (gi) exhibit enhanced barrier properties in comparison with analogue.
Сonclusions
1. Atmospheric corrosion inhibitor N-M-1(gi) is effective to steel protection from electrochemical and microboilogical corrosion and may be used as universal addition for all type preservatives. 2. Experimental studies are shown thatN-H-1(gi) is recommended for preservation of pipes and equipment internal surfaces instead of import analogue CortecVpCI-649 BD.
