| 摘要 |
The present invention relates to a system (100) for manufacturing a Field Joint Coating (11), the system comprising: - a heating device (102) for heating a quantity of a polymer, - an upstream pump (104) for pumping the quantity of heated polymer into a storage compartment (106) of an ejection device (108), - the ejection device (108) which is constructed for each time ejecting the heated polymer from its storage compartment, the ejection device comprising: o a barrel (110) which defines the storage compartment, the barrel being reinforced and configured for repeated use, o a plunger (11), o an actuator (114) for driving the plunger through the barrel for emptying the storage compartment, - a downstream pump, the downstream pump being constructed for increasing the operating pressure of the ejected polymer, - a mould (200) configured to be positioned at a field joint (13) around a pipeline. |
