Abstract
The invention relates to a welding method for a middle shell cover, with a reinforcing ring, of a reforming reactor. The method includes two steps: (1), assembling the reinforcing ring after being blanked with the middle shell cover, leveling and centering the reinforcing ring, adjusting gaps between the reinforcing ring and space around a groove of a central hole of the middle shell cover, controlling the end face of the reinforcing ring to be parallel to a port of the middle shell cover, and welding the reinforcing ring with the middle shell cover; and (2), after leveling and centering a shell ring, installing and welding the middle shell cover with the reinforcing ring with corresponding shell ring, controlling the end face of the reinforcing shell to be parallel to a port of the shell ring; after rounding and centering according to outer surfaces of two ports of the shell ring, processing the end face of the reinforcing ring and the ports of the shell ring, and processing threaded holes around the reinforcing ring. The welding method for a middle shell cover, with the reinforcing ring, of the reforming reactor is convenient to operate and capable of well guaranteeing levelness of the reinforcing ring and verticality of the threaded holes.
Description
Technical field
The present invention relates to the welding method of reforming reactor internals in the field of petrochemical industrial, relate in particular to the welding method of the middle end socket of reforming reactor band reinforcing ring.
Background technology
Reforming reactor is with space in the middle end socket partitioned bottle, and middle end socket center is useful on the reinforcing ring that connects middle end socket and central tube base.Because the perpendicularity to central tube in welding process requires relatively stricter, so the requirement to the perpendicularity of the levelness of the influential reinforcing ring of central tube perpendicularity and bolt hole is just relative higher, therefore, the welding method of the middle end socket of band reinforcing ring just seems especially important.
The welding method of the middle end socket of existing band reinforcing ring:
First method: after single part is made by drawing, assembling welding by drawing again.The method requires very high to assembling, the levelness of reinforcing ring and the perpendicularity of bolt hole all are difficult to guarantee.
Second method: preparatory processing both ends of the surface after the reinforcing ring blanking (the sealing surface place does not process and puts in place is the thickness made allowance), the auger shell keyhole, then with middle end socket assembly welding after again with the cylindrical shell assembly welding, process the reinforcing ring sealing surface afterwards to the drawing requirement.This method can well guarantee the levelness of reinforcing ring, but the perpendicularity of bolt hole is difficult to guarantee.
Summary of the invention
Technical problem to be solved by this invention provides the welding method of middle end socket of reforming reactor band reinforcing ring of the perpendicularity of a kind of levelness of being convenient to operate, guarantee reinforcing ring and bolt hole.
For addressing the above problem, the welding method of the middle end socket of reforming reactor band reinforcing ring of the present invention is characterized in that: this method comprises following two steps:
(1) after the reinforcing ring blanking, first and middle end socket assembling, with its levelling on platform, centering, it is parallel with middle end socket port with gap, control reinforcing ring end face around the middle end socket centre bore groove to adjust reinforcing ring, then reinforcing ring and middle end socket is welded;
(2) with shell ring behind levelling on the platform, centering, the middle end socket that has reinforcing ring and corresponding shell ring are carried out assembly welding, control reinforcing ring end face is parallel with the shell ring port; Process reinforcing ring end face and shell ring port after looking for circle, centering according to shell ring two-port outer surface afterwards, process reinforcing ring border bolt hole at last.
Described reinforcing ring blanking should be welded into whole and smoothing when being the distinguish blanking.
The present invention compared with prior art has the following advantages:
1, the present invention repeatedly carries out sealing surface and processing at last of bolt hole of levelling, centering operation and reinforcing ring, thereby can well guarantee the levelness of reinforcing ring and the perpendicularity of bolt hole.
2, the present invention is simple to operate and reliability is high.
The specific embodiment
The welding method of the middle end socket of reforming reactor band reinforcing ring, this method comprise following two steps:
(1) after the reinforcing ring blanking, first and middle end socket assembling, with its levelling on platform, centering, it is parallel with middle end socket port with assurance gap uniformity, control reinforcing ring end face with the gap around the middle end socket centre bore groove to adjust reinforcing ring, then reinforcing ring and middle end socket are welded, notice during welding preventing that welding deformation and postwelding from carrying out stress-removal annealing heat treatment;
(2) with shell ring behind levelling on the platform, centering, the middle end socket that has reinforcing ring and corresponding shell ring are carried out assembly welding, control reinforcing ring end face is parallel with the shell ring port, postwelding carries out the stress-removal heat treatment of annealing; Process reinforcing ring end face and shell ring port after looking for circle, centering according to shell ring two-port outer surface afterwards, process reinforcing ring border bolt hole at last.
Should be welded into whole during the blanking of reinforcing ring distinguish and smoothing.
Claims (2)
1. the welding method of the middle end socket of reforming reactor band reinforcing ring, it is characterized in that: this method comprises following two steps:
(1) after the reinforcing ring blanking, first and middle end socket assembling, with its levelling on platform, centering, it is parallel with middle end socket port with gap, control reinforcing ring end face around the middle end socket centre bore groove to adjust reinforcing ring, then reinforcing ring and middle end socket is welded;
(2) with shell ring behind levelling on the platform, centering, the middle end socket that has reinforcing ring and corresponding shell ring are carried out assembly welding, control reinforcing ring end face is parallel with the shell ring port; Process reinforcing ring end face and shell ring port after looking for circle, centering according to shell ring two-port outer surface afterwards, process reinforcing ring border bolt hole at last.
2. the welding method of the middle end socket of reforming reactor band reinforcing ring as claimed in claim 1 is characterized in that: described reinforcing ring blanking should be welded into whole and smoothing when being the distinguish blanking.
