contents Mont Saint-Michel is known all over the world forits architecture and the natural beauty of the site.It has been listed as a UNESCO world heritage sitesince 1979.For decades, Saint-Gobain PAM has been using thesurrounding salt marshes as a test bed for its newcoatings, including the TT range of coatings.The polders surrounding the mount are aparticularly corrosive environment. Resistivity ofthe soil in the salt marshes near Mont-Saint-Michel is almost 100 Ω.cm, making the locationan excellent natural test facility in which to assessthe performances of ductile iron pipe coatings.

introduction

2/3Buried pipes are subjected to various loads and aggressions, including soil and backfillcorrosivity. Standard version of Saint-Gobain PAM pipes feature either a conventional zinccoating or the new ZINALIUM coating, which provide a sufficient level of corrosion resistancefor most situations. However, the soils's corrosivity must be assessed to determine whetherspecial protective measures and high performance coatings are required. Saint-GobainPAM engineering teams carry out soil analyses on customers' request.General corrosion indicatorsGeneral corrosion indicators are determined with a detailed map which indicates: spots are wet and unaerated, therefore likely to be more corrosive, other low areas rich in humic acids and bacteria, and often polluted,Pollution and specific corrosion indicatorsUsing plans (available from public authorities), the following are determined: waste, or by sewage, mainly from households, structures, electric traction systems, plants, etc.).fThis survey indicates the various strata crossed and provides information on the nature ofthe soil and its natural corrosivity

Saint-Gobain PAM packagesTT range products with great care,to ensure that they are suppliedin perfect conditions.These products should be handledusing appropriate tools.Saint-Gobain PAM supplies specialhandling hooks designedspecifically for the TT product range.Contact us for more information.

32/33Connecting TT PE pipesConnecting collars, available in sizes DN 80 to 250, can be fitted directly over the HDPEcoating on TT PE pipes. Bolts should be tightened to at least 8 m.daN.For DN 300 to 700 pipes, the PE polyethylenecoating must be removed before fittingthe collar. The assembly must then becorrosion-protected with a heat-shrinkcollar (or equivalent protection).PAM supplies a range of connectingcollars with reinforced coatingsfor TT products.Depending on the corrosivity risk of the soil, a heatshrinkcollar may be required to provide additional protection to the connection.For further information, please contact our sales engineers.
