CYCLOHEXYLAMINE FOR CORROSION PREVENTION: IN STEAM‐RAISING EQUIPMENT Available to Purchase

The treatment of water for use in steam‐raising plants has two primary objects: firstly, to maintain efficiency of operation by preventing the formation of scales and deposits on heating and cooling surfaces and in water‐carrying pipelines and, secondly, to prolong the life of the equipment by preventing corrosion of metal surfaces with which the water comes into contact. Corrosion is perhaps less obvious because the effects are not always evident until it is too late and replacement of corroded sections becomes necessary. Troubles caused by the accumulation of corrosion products, and damage by corrosion, can be avoided if appropriate agents are employed to treat the water circulating in the system. This article describes the properties and use of cyclohexylamine, a material which has found widespread application for the treatment of boiler water to prevent corrosion of metal surfaces by dissolved carbon dioxide.
