ANZCO foods Rakaia hot wa­ter ring main pipe re­place­ment

DEMM Engineering & Manufacturing - - HYDRAULICS & PNEUMATICS -

ANZCO Foods Rakaia needed to re­place their leak­ing hot wa­ter ring main pipe work, along with lat­er­als which supplied var­i­ous lines through­out the plant. The pro­ject pre­sented a num­ber of chal­lenges to their en­gi­neer­ing team who would un­der­take the work.

Firstly, they wanted to in­stall a pipe sys­tem that would pro­vide a leak-free, long ser­vice life to elim­i­nate the on­go­ing main­te­nance that the pre­vi­ously in­stalled pipework re­quired.

The big­gest chal­lenge was that what­ever sys­tem was se­lected, it needed to be in­stalled within the tight con­straints of sur­round­ing pipe work and wall pen­e­tra­tions. As the pipework was sus­pended over­head, be­ing able to utilise the ex­ist­ing pipe sup­port sys­tem would be ben­e­fi­cial.

ANZCO se­lected MM Kem­bla’s KemPress Stain­less Steel press fit sys­tem for the pro­ject. Be­ing made of 316L stain­less steel it had proven ser­vice life in sim­i­lar ap­pli­ca­tions and a 25 year leakproof war­ranty. The speed and ease of in­stalling the KemPress sys­tem meant that ANZCO’s own en­gi­neer­ing team could un­der­take the work. The flame free na­ture of the KemPress Stain­less Steel sys­tem meant it was ideal to in­stall close to the ex­ist­ing plas­tic pipework.

ANZCO’s en­gi­neer­ing team in­stalled over 260 me­tres of pipe work, rang­ing from 76mm for the ring main down to 15mm for the var­i­ous lat­er­als. As the KemPress Stain­less Steel was lighter than the pipe work it was re­plac­ing, ANZCO utilised the ex­ist­ing pipe sup­port sys­tem.

The in­stal­la­tion took around 140 man hours to com­plete, be­ing sig­nif­i­cantly quicker com­pared to weld­ing the pipework. ANZCO’s Engi­neer, Tony MacKay com­mented that “due to the tight space we had to work around the other plas­tic pipework, we sim­ply couldn’t have done the in­stal­la­tion any other way.”
