High temperature fluid pipeline sealed heat insulation cabin penetrating device and installation method thereof

Abstract

The invention provides a high temperature fluid pipeline sealed heat insulation cabin penetrating device and an installation method thereof. The high temperature fluid pipeline sealed heat insulation cabin penetrating device comprises a high temperature fluid pipe (6), a stuffing box (1) and a stuffing box pressing box (2), the high temperature fluid pipe (6) is sleeved in the stuffing box (1) and penetrates through an inner hole (10) on the stuffing box pressing cover (2), a uniform gap is reserved between the high temperature fluid pipe (6) and the hole wall of the inner hole (10), the stuffing box (1) penetrates through a deck (7) or a cabin wall (8) to be welded to the deck (7) or the cabin wall (8), muddy fillers (3) are filled in the remaining space of the inner portion of the stuffing box (1), graphite packing (4) is filled at two ends of the stuffing box (1), and the graphite packing (4) extends out of the end face of the stuffing box (1) to be tightly contacted with the end face of the stuffing box pressing cover (2). The installation method includes the following steps: rust removal and painting of the stuffing box (1) and the stuffing box pressing cover (2), through installation of the stuffing box (1), through installation of the high temperature fluid pipe (6), filling of sealing fillers, inspection and heat insulation wrapping.

Description

technical field [0001] The invention relates to a tank piercing device, more specifically to a high-temperature fluid pipeline sealing and heat-insulating tank penetration device and an installation method thereof, belonging to the technical field of pipeline penetration of ships and marine engineering. Background technique [0002] Asphalt ships and other ships carrying high-viscosity fluid cargoes that require heat tracing are mainly used to carry liquid asphalt or oil products between 45°C and 200°C. Bitumen, the final product of crude oil, is semi-solid at normal temperatures; it must be heated to the appropriate temperature in order to pump it from a refinery to a ship, or to discharge it from a ship into a storage vessel onshore , and this high temperature should always be maintained during the voyage. The suitable temperature for lightering general asphalt is about 160°C, and the suitable temperature for some demanding asphalt is as high as 250°C. In order to keep th...
