Modular pipe formation apparatus

A modular plastic pipe formation apparatus to extrude plastic pipe comprising a plurality of modules in the form of transportable containers wherein each module comprises at least one component of a pipe forming apparatus located therein, the apparatus further comprising:

• a closed circuit fluid cooling system to provide cooling fluid to the at least one component of more than one of the plurality of modules, the fluid cooling system comprising a further module in the form of a transportable container, and a hot water storage tank, a cold water tank and a heat exchanger housed within the further module, the cooling circuit system having an inlet port to the further module from a first of the more than one of the plurality of modules and an exit port from the further module to a second of the more than one of the plurality of modules;
• and
• a cooling arrangement to cool the fluid in the closed circuit fluid cooling system, the cooling arrangement comprising a chiller fluid circuit and a pre-cooling arrangement, wherein both the fluid of the cooling circuit system and the chiller fluid circuit pass through the heat exchanger to cause cooling of the fluid in the fluid cooling circuit system and the pre-cooling arrangement is arranged to cool heated fluid in the fluid cooling circuit system prior to introduction into the heat exchanger.
