Arm connection reinforcement node that the object of this invention is to provide a kind of High Temperature High Pressure large-diameter pipeline and preparation method thereof, solve arm connected node and add the problem that competent structure takes up room.Structure way of the present invention and arm pedestal similar, effectively can strengthen arm connected node in limited little space, spatial adaptation is very capable.
For achieving the above object, first aspect present invention provides a kind of arm connection reinforcement node of High Temperature High Pressure large-diameter pipeline, described reinforcement node comprises supervisor and the arm of T-shaped connection, described supervisor and arm vertical welding, described supervisor is socketed at Nodes and supervisor's sleeve pipe, described arm is socketed at Nodes and arm sleeve pipe, Zhi Guanhuan week described in Nodes is socketed with annular stiffened plate, between arm annular stiffened plate and supervisor's sleeve pipe, is connected with radial stiffened plate perpendicular in arm diametric(al); Arm annular stiffened plate and supervisor sleeve pipe between and between radial stiffened plate, be connected with the lateral stiffening plate being parallel to arm axis.
Second aspect present invention provides a kind of preparation method of arm connection reinforcement node of High Temperature High Pressure large-diameter pipeline, and the preparation method of described reinforcement node comprises the following steps: 1) supervisor's sleeve pipe and pipe-in-pipe are wrapped in respectively and are responsible for and on arm; 2) on arm, distance edge certain distance arranges annular stiffened plate; 3) between arm annular stiffened plate and supervisor, radial stiffened plate is set perpendicular to arm diametric(al), radial stiffened plate is circumferentially evenly arranged at arm, and radial stiffened plate and arm annular stiffened plate, arm, supervisor's contact position are all welded to connect; 4) between radial stiffened plate, arranges the lateral stiffening plate being parallel to arm axis between arm annular stiffened plate and supervisor's sleeve pipe, the intersection line of the annular stiffened plate of lateral stiffening plate and arm, radial stiffened plate, supervisor is all welded to connect.
Compared with prior art the present invention has following characteristics and beneficial effect:
After adopting technology of the present invention, pipeline branch pipe connected node position stress performance obviously improves, and the stress level of pipeline relation line position material obviously declines; The structural strain's of arm connected node is effectively controlled; Effectively strengthened by the supervisor that arm weakens.
Of the present inventionly add strong method and put formation annular girder at branch pipe connecting position, on the arm that cuff is put at branch pipe connecting position, add the rigidity of arm, effectively overcome supervisor weakened by arm after the deformation tendency that expands outwardly in interior pressure of arm.Reinforing function and the arm pedestal of this reinforcement way are similar, but material consumption comparatively arm pedestal significantly reduce, and simple structure, easy to make, easily realize.
Due to working principle of the present invention and arm pedestal similar, the space hold therefore adding competent structure is very little, does not need to add strong method by traditional stiffened plate and uses roomy stiffened plate to take large area space.Therefore arm connected node of the present invention adds strong method can have extensive adaptability as arm pedestal, can in limited space, make pipeline branch pipe connected node effectively be strengthened.
