In one embodiment, the invention provides a rupture disk assembly having a rupture disk and a rupture disk holder. The rupture disk holder has a first annular member downstream of the rupture disk, a second annular member upstream of the rupture disk, and an optional third annular member upstream of the second annular member. An outer peripheral portion of the rupture disk is sandwiched between the first and second annular members; and, if a third annular member is present, (a) the second annular member is sandwiched between the outer peripheral portion of the rupture disk and the third annular member, and (b) the third annular member includes a fluid port aimed at the rupture disk. However, if the third annular member is not present, the second annular member includes a fluid port aimed at the rupture disk. In another embodiment, the invention provides an equipment access assembly having an equipment access cover, an equipment access cover mount, and an annular member between the equipment access cover and cover mount. The annular member includes a fluid port aimed at the equipment access cover. In yet another embodiment, the invention provides a valve mounting assembly having a downstream valve mount, an upstream valve mount, a valve intermediate the downstream and upstream valve mounts, and an annular member intermediate the valve and the upstream valve mount. The annular member includes a fluid port aimed at the valve.
