Abstract: A server system facilitates an exchange of messages with a remote client application. The server system includes a plurality of application servers hosting a plurality of applications. A plurality of Application Program Interfaces (APIs) provides programmatic access to the plurality of applications, each of the APIs being configured to receive request messages compiled by the remote client application. First and second request messages, respectively addressed to first and second APIs of the plurality of APIs by a remote client application, each comprise at least one common data component. Further, the first request message includes a first payload specific to the first API, and the second request message includes a payload specific to the second API.

Abstract: The present invention relates to the joining of lined pipes, particularly lined pipes for high pressure applications. A metal pipeline section that has a metal flange (13) at one end is lined with a plastic liner (15) such that some of the liner extends beyond the flange end (13) of the pipeline section. An annular plastic member (16) is electrofusion joined onto the outside of the portion of plastic liner (15) which extends beyond the flange end (13) of the pipeline section and any liner extending beyond the annular plastic member is trimmed off to make the liner flush with the annular plastic member (16). The annular plastic member (16) is then positioned adjacent the annular plastic member of another similarly prepared pipeline section and a containment ring (17) is secured around them to restrain any outward movement of the annular plastic members when the pipeline is in use.
