Pipe re­ha­bil­i­ta­tion with­out sur­face dis­rup­tion

RHINO LIN­INGS’ Cast- in- Place epoxy resin can re- line dam­aged and cor­roded pipes with­out dig­ging up the in­fra­struc­ture.

A mesh sleeve – like a large tube sock – is soaked in the resin and then pulled through a length of pipe. The sleeve is in­flated with air or steam to con­form to the con­tours of the pipe and al­lowed to cure, form­ing a new, smooth in­ner sur­face. The sys­tem can even con­tend with pipes that have bends up to 90 de­grees in them.

Pe­ter Mor­gan, Man­ag­ing Di­rec­tor of Rhino Lin­ings Aus­tralia said the CIPP method was in­creas­ingly be­ing used by coun­cils and util­ity com­pa­nies to re­pair wa­ter and sewer pipes. “CIPP is ideal for both the struc­tural and lat­eral wa­ter pipes in our cities,” he added. “Struc­tural are the main pipes usu­ally found un­der roads, while lat­eral are those that run from the street to a prop­erty.”

The resin and hard­ener sys­tem is de­signed to have a life span of a min­i­mum of 50 years. This life span is de­pen­dent on us­ing the sys­tem in ac­cor­dance with Rhino Lin­ings Prod­uct Data Sheet and fol­low­ing the meth­ods of the rel­e­vant Stan­dards. Mor­gan said that de­pend­ing on the con­straints and re­quire­ments of the project, there are a range of hard­en­ers that es­sen­tially pro­vide fast, medium or slow cur­ing times. The fast- act­ing cur­ing agent al­lows for a less in­va­sive re­place­ment pro­ce­dure al­low­ing projects to be com­pleted on time and within bud­get.

The Gold Coast- based com­pany prom­ises pro­vide a stream­lined in­ven­tory model and prompt ship­ments to all lo­ca­tions across the Aus­tralasian re­gion, re­gard­less of quan­ti­ties re­quired.
