Abstract
The invention relates to an explosive welding process for internal or external explosion of a composite pipe joint. The process comprises the following steps of: performing polishing treatment on the internal surface of a basic pipe and the external surface of a composite pipe; assembling the basic pipe with the composite pipe, wherein the basic pipe is arranged outside, the composite pipe is arranged inside, and the gap between the basic pipe and the composite pipe is 1 mm; putting the assembled basic pipe and composite pipe in an external medicine box of which the bottom is provided with a base plate, wherein an internal medicine box is arranged in the middle of the composite pipe; filling 10 mass percent of heavy diesel fuel into the space between the composite pipe and the internal medicine box and the space between the basic pipe and the external medicine box; fully mixing; sealing; storing powdery extrusion ammonium oil low-velocity explosives for 48 hours; arranging powdery extrusion ammonium oil high-velocity explosives without the heavy diesel oil above the low-velocity explosives; and detonating the high-velocity explosives by using a detonator to finish welding and form a clad pipe. In the subsequent machining and welding processes, interface cracking and layering phenomena can be prevented.
Description
Technical field
The present invention relates to the explosive welding metallic composite and make the field, be specifically related to execute quick-fried explosion weld process inside and outside a kind of multiunit tube joint that welds zirconium 60702/ stainless steel 321.
Background technology
Zirconium 60702 has good nuclearity energy, is the indispensable structural material of atomic energy industry.In order in nuclear engineering is built, to save this rare and valuable metal material to reduce construction costs, can in nuclear reactor, use zirconium alloy pipe, and use relatively inexpensive stainless steel tube out-of-pile, so just produced the tubing Welding Problems of two kinds of different physics and chemistry character.Explosive welding zirconium/stainless steel composite pipe joint can address this problem effectively: the zirconium tube portion welding of the zirconium Guan Keyu multiunit tube joint in the nuclear reactor; And the outer stainless steel tube of nuclear reactor can weld with the stainless steel joint for pipeline of multiunit tube joint, thereby effectively realizes in the nuclear reactor outer by the purpose of zirconium tube transitions to stainless steel tube to nuclear.
As everyone knows, generally multiple layer is thinner, basic unit is thicker for the explosive welding metal composite pipe, usually adopts outer quick-fried or internal explosion process production, when multiple layer during at inwall, should adopt internal explosion process, otherwise then should adopt external explosion process.The metal composite pipe that is used for the making pipe joint is shorter, generally adopts internal explosion process.When adopting internal explosion process, because the instantaneous pressure of explosive detonation ripple is very large, the pipe joint that explode after compound very easily ftractures, and then becomes the blast fragment in the time of seriously, causes irremediable economic loss and serious security incident.So outer tube need to be used for absorbing and transmitting the dump energy of detonation wave according to calculating making privacy protection mould, guarantees that multiple tube has set size and dimension, prevent exploding welding multiple tube or pipe joint are out of shape excessive or burst.Because explosion velocity of explosive increases with the increase of density, to multiple tube or pipe joint cloth medicine the time, the situation that the bottom explosive density is far longer than the top explosive density inevitably appears, it is different to the application of force of multiple tube or pipe joint top and bottom explosion velocity of explosive or detonation wave pressure to occur like this, and undesirable taper dimensions appears in the multiple tube after the explosive welding or pipe joint.For taper dimensions appears in multiple tube and pipe joint after the prevent exploding welding, usually make a positive taper inner tube mould according to charge depth, also be the explosive payload of reduce multiple tube or pipe joint bottom, consistent from upper end to the lower end of pipe with the explosion velocity or the detonation wave pressure that guarantee explosive.Like this, although can guarantee to a certain extent welding quality and the preliminary dimension of explosive welding multiple tube or pipe joint, but seem comparatively complicated in inner and outer pipe Mold Making and cloth prescription formula, not only the Mold Making cycle is long, cost is large, and the inner and outer pipe mould is out of shape serious even broken after explosive welding, not reproducible utilization has strengthened the explosive welding cost of multiple tube or pipe joint.For this reason, must seek the explosive welding that effective method is more economically realized metal composite pipe or pipe joint.
Summary of the invention
