Abstract
A kind of plugging structure of low temp area inert gas micro-positive pressure protection pipeline, including：Closure steel plate on end of line flange, the gasket seal being arranged on blocking steel plate, the flange section being arranged on gasket seal, wherein hard gasket is provided on flange section；It blocks steel plate, gasket seal, flange section and hard gasket to be connected integrally by stud, and fixation is tightened with nut at both ends.When the utility model can not only be transported at sea, preservation is sealed to low temp area inert gas micro-positive pressure protection pipeline；It can also enough alleviating site operation workload, solves the problems, such as that the site workload that scene need to largely remove is big, greatly improve work efficiency, reduce production cost, facilitate site operation.
Description
Technical field
The utility model is related to pipeline more particularly to a kind of spiral shells for protecting pipeline for low temp area inert gas micro-positive pressure
Bolt fastening structure.Belong to Offshore Engineering field.
Background technology
Currently, when existing pipeline at sea transports, preservation need to be sealed to pipeline with inert gas micro-positive pressure, so that
Pipeline is protected.Pipeline is generally blocked using welding pipe cap；After pipeline at sea transports arrival low temp area, then cut off
End pipe cap, welding cleaning tooling carry out pipeline cleaning, and cleaning rear line restores, then welds pipe cap and carry out air seal test.Due to
It is fixed that welding, which blocks, there is a large amount of dismounting work, certain trouble is brought to follow-up work.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and provide a kind of low temp area
Inert gas micro-positive pressure protects the plugging structure of pipeline, micro- to low temp area inert gas when can not only at sea transport
Positive pressure protection pipeline is sealed preservation；It can also enough alleviating site operation workload, solving scene need to largely remove
The big problem of site workload, greatly improve work efficiency, reduce production cost, facilitate site operation.
The purpose of this utility model is realized by following technical scheme：
A kind of plugging structure of low temp area inert gas micro-positive pressure protection pipeline, it is characterised in that：Including：Mounted on pipe
Closure steel plate on line end flange, the gasket seal being arranged on blocking steel plate, the flange section being arranged on gasket seal,
Wherein, it is provided with hard gasket on flange section；Steel plate, gasket seal, flange section and hard gasket are blocked by stud
Series connection is integral, and tightens fixation with nut at both ends.
The stud is：1/2 cun of stud after undergauge.
The hard gasket is low temperature carbon steel backup plate；Wherein, spacer thickness is：6mm；Gasket outer diameter is：27mm-190mm；
Gasket internal diameter is：13.5mm.
The beneficial effects of the utility model：The utility model due to the adoption of the above technical scheme, can not only be at sea
When transport, preservation is sealed to low temp area inert gas micro-positive pressure protection pipeline；It can also enough alleviating site operation
Workload solves the problems, such as that the site workload that scene need to largely remove is big, greatly improves work efficiency, reduction is produced into
This, facilitates site operation.
