Abstract
The utility model discloses a pressure test connection structure for a pressure test end socket and an overlay welding reinforcing pipe orifice, which comprises a pressure test end socket and an overlay welding reinforcing pipe, wherein the overlay welding reinforcing pipe comprises a reinforcing pipe; the inner wall of the reinforcing pipe is provided with an overlay welding layer; the outer wall of the orifice end of the reinforcing pipe is a slope; the overlay welding layer extends to the groove of the outer wall slope of the reinforcing pipe orifice; the slope is also provided with a pressure test lug boss; and the pressure test end socket is welded on the pressure test lug boss. The utility model has the advantage of simple structure; and in the pressure test process, the pressure test end socket is directly connected with the pressure test lug boss without influencing the overlay welding layer, and additional partial stress relief heat treatment, nondestructive inspection and the like are not needed, thereby greatly reducing the workload, enhancing the work efficiency and lowering the production cost. The utility model is applicable to pressure test connection of all pressure test end sockets and overlay welding reinforcing pipe orifices.
Description
Technical field
The utility model relates to the pressure testing of the pressure testing head and the built-up welding reinforcement pipe mouth of pipe and uses syndeton.
Background technology
Some uncovered built-up welding reinforcement pipes with the forging making are often arranged in the mesohigh pressure vessel, and its structure comprises: the reinforcement pipe, and the reinforcement inside pipe wall is provided with overlay cladding, and reinforcement pipe nose end outer wall is the slope, and overlay cladding extends on the groove on reinforcement pipe mouth of pipe outer wall slope.Built-up welding reinforcement pipe is wanted pressure testing usually, when making built-up welding reinforcement pipe, and the not built-up welding earlier of pipe end groove; Generally stay the pressure testing surplus about 30mm at pipe end; Pressure testing head is welded on the port of pressure testing surplus, and 30mm pressure testing surplus and pressure testing head that pressure testing after finishing is used pressure testing cut off in the lump, grind groove at nose end again; Carry out the built-up welding at groove place then, the groove built-up welding is carried out local stress-removal thermal treatment and Non-Destructive Testing after finishing again.The syndeton that above-mentioned pressure testing is used workload in actual mechanical process is bigger, the higher and complex steps of cost.
The utility model content
The problem that the utility model need solve provide a kind of simple, workload is few, cost is low pressure testing head and syndeton is used in the pressure testing of the built-up welding reinforcement pipe mouth of pipe.
For addressing the above problem; The technical scheme that the utility model adopts is: syndeton is used in the pressure testing of the pressure testing head and the built-up welding reinforcement pipe mouth of pipe, comprising: pressure testing head and built-up welding reinforcement pipe, and wherein built-up welding reinforcement pipe comprises: the reinforcement pipe; The reinforcement inside pipe wall is an overlay cladding; The mouth of pipe end outer wall of reinforcement pipe is the slope, and overlay cladding extends on the groove on reinforcement pipe mouth of pipe outer wall slope, also is provided with the pressure testing boss on the slope; Pressure testing head is welded on the pressure testing boss.
The utility model has the advantages that: simple in structure, pressure testing head directly is connected with the pressure testing boss during pressure testing, and overlay cladding and groove are not had influence; Need not to carry out in addition local stress-removal thermal treatment and Non-Destructive Testing etc.; Workload reduces, and has improved work efficiency, has reduced production cost.
Description of drawings
Fig. 1 is that the syndeton synoptic diagram is used in the pressure testing of the described pressure testing head of the utility model and the built-up welding reinforcement pipe mouth of pipe.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
As shown in Figure 1; Syndeton is used in the pressure testing of the pressure testing head and the built-up welding reinforcement pipe mouth of pipe, comprising: pressure testing head 1 and built-up welding reinforcement pipe 2, and built-up welding reinforcement pipe 2 comprises: reinforcement pipe 3; Reinforcement pipe 3 inwalls are overlay cladding 4; The mouth of pipe end outer wall of reinforcement pipe 3 is slope 5, and overlay cladding 4 extends on the groove on reinforcement pipe 3 mouth of pipe outer wall slopes 5, on slope 5, also is provided with pressure testing boss 6; Pressure testing head 1 is welded on the pressure testing boss 6.
During pressure testing, pressure testing head 1 directly is welded on the pressure testing boss 6, after pressure testing is accomplished pressure testing head and pressure testing boss 6 is cut off in the lump and get final product.This kind syndeton is very simple, practical, and the overlay cladding 4 of reinforcement pipe 3 inwalls can finish in disposable built-up welding.Need not according in the traditional approach, wait pressure testing to finish the back groove section on built-up welding slope in addition, and the overlay cladding of built-up welding at twice also need carry out local stress-removal processing, Non-Destructive Testing etc., workload is quite big.The pressure testing of the pressure testing head described in the utility model and the built-up welding reinforcement pipe mouth of pipe significantly reduces workload with syndeton, has improved work efficiency, has reduced production cost.
Claims (1)
1. syndeton is used in the pressure testing of the pressure testing head and the built-up welding reinforcement pipe mouth of pipe; Comprise: pressure testing head and built-up welding reinforcement pipe; Wherein built-up welding reinforcement pipe comprises: reinforcement pipe, reinforcement inside pipe wall are overlay cladding, and the mouth of pipe end outer wall of reinforcement pipe is the slope; Overlay cladding extends on the groove on reinforcement pipe mouth of pipe outer wall slope, it is characterized in that: also be provided with the pressure testing boss on the slope; Pressure testing head is welded on the pressure testing boss.
