The coating apparatus (10) comprises a coating device (12) for depositing a solvent free, curable liquid organic precursor for said organic coating layer and a curing unit (14) for curing the liquid organic precursor deposited on said substrate (S) by supplying energy to said liquid organic precursor. The coating system further comprises a vacuum pump (30) that, while coating, maintains a pressure inside said coating chamber below 1 mbar. A supply facility (152, 152′) for controllably supplies the curable liquid organic precursor from the reservoir to the coating device (12), The supply facility (152, 52′) has an input (1510) for receiving curable liquid organic precursor from the reservoir. A position of a bottom (150B) of the reservoir is arranged at a height (H1) above the input (1510). The coating system has a first operational mode wherein curable liquid organic precursor to be supplied to the coating apparatus is exposed to a vacuum having a pressure with a first pressure value that is equal to or lower than the chamber pressure value, and has a second operational mode following the first operational mode, wherein the supply facility (152, 152′) supplies the curable liquid organic precursor to the coating device (12).

Abstract: An apparatus for powder coating a welded pipe joint includes a coating head having a powder chamber and at least one vacuum chamber. The coating head is mounted to a carriage operable to circumferentially traverse a pipe workpiece. The powder chamber has at least one inlet for receiving an air/powder suspension, and at least one outlet for delivering the air/powder suspension to a pre-heated weld zone of the pipe, such that the suspension fuses to and coats the weld zone. The vacuum chamber has at least one powder inlet for receiving excess air/powder suspension from the weld zone, and is connectable to a source of vacuum for exhausting the excess air/powder suspension from the weld zone. The coating thickness in the weld zone can be controlled by coordinated regulation of the air/powder flow rate into the powder chamber and the exhaust flow rate from the vacuum chamber.
