Described closed and locked device one end is equipped with hinge and can amounts to switching, and the other end is equipped with snap close, can lock when upper and lower casing is closed, forms the one circular groove.
Described upper and lower casing is part-annular.
The outside of described upper and lower casing and housing shaft are provided with the insulation groove of symmetry to outer wall.
Described upper and lower casing two ends are provided with axial shrouding and notch, and axial shrouding can insert notch and regulate, and mates the caliber of different oil transport pipelines.
The axial two ends of described upper and lower casing are provided with the radius short circuit.
Be welded with some stiffening plates in the described upper and lower casing.
Described filling mouth is provided with slide cover, and described housing top offers chute, and slide cover is installed in the chute, can be free to slide closure.
By means of this refrigerating plant, realized the construction fire operation of the variety of way of carrying out at oil transport pipeline band oil, it is simple in structure, the snap frozen of High Temperature High Pressure oil transport pipeline can be provided, can when accident condition, freeze operations such as reaching the perforate of effectively getting angry, welding, pipeline butt joint by pipeline band oil cooling, and can change adjusting according to different oil transportation calibers and use with the coupling that this reaches different tube diameters, simultaneously free from environmental pollution again, reduced cost.
