    Is anybody aware of a seismic/expansion joint connector that meet these requirements?? 

    We have looked a couple of different manufacturers and none of them meet the 1000° and only smaller sizes meet the PSI.. Metallic flexible joints shall be permitted in the

    pipeline where required for expansion joints, seismic protection,

    thermal expansion, or vibration control and shall be as follows:

    (1) For all wetted surfaces, made of bronze, copper, or stainless


    (2) Cleaned at the factory for oxygen service and received on

    the job site with certification of cleanliness

    (3) Suitable for service at 2070 kPa (300 psig) or above and

    able to withstand temperatures of 538°C (1000°F)

    (4) Provided with brazing extensions to allow brazing into the

    pipeline per

    (5) Supported with pipe hangers and supports as required for

    their additional weight

    We spoke with Beacon Rep about these also.. Don't believe they meet 1000° either..
