Corrosion Studies of Iron In the Presence of Sulfur

Results of Research on Sulfur Jointing Compounds

“…plasticized sulfur cements have been shown to be many times less corrosive. 'under the same test conditions (5,6). 'Actually, plasticized sulfur cements are widely used to protect steel from' corrosion (7,8).…”

“…7~;:.· . d' Other investigations' have sho~n that cast iron or steel completely embedded in a plasticized sulfur cement is not attacked after long immersion in water (9). Although cast-iron pipe has been joined successfully with sulfur cements for more than 30 years (10), difficulty in some specific localities has caused concern.…”

Performance Studies on Sulfur Jointing Compounds

“…This formulation, which meets Federal Specifications SS-C-608 for both hot-and cold-water mains, will be referred to subsequently as the "Atlas" formula, and is given in Table 1. Information obtained from this research program includes a brief history and a comparative report on various jointing materials and methods (3), the development of torsion testing equipment for cylindrical specimens (4), the physical properties of plasticized sulfur cements (5) and corrosion studies of iron in the presence of sulfur (6). of a bactericide, a proprietary mixture of sulfur, tar and oil used as a jointing material in earthenware pipe in Colombo tended to become oxidized to sulfate on the surface.…”
