Embodiment Construction

[0014] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Provided in conjunction with the accompanying drawings, a method for preparing an explosive composite pipe in a partial vacuum environment using water pressure comprises the following steps:

[0016] 1) From the inside to the outside, the pipe to be composited 1, the pipe to be composited 2, the small-sized PVC pipe 3-1, and the large-sized PVC pipe 3-2 are coaxially arranged between the PVC pipe 3-1 and the PVC pipe 3-2 Filling with explosives and detonators to form an explosive device 3;

[0017] 2) Seal and vacuum both ends of the gap between the pipe to be composited 1 and the pipe to be composited 2 with a sealing strip to construct a vacuum gap environment 4;

[0018] 3) Fill water between the pipe to be composited 2 and the explosive device to construct a water environment 5 .

[0019] 4) The detonation explosive...

Abstract

The invention provides a method for preparing an explosive composite tube in a local vacuum environment through water pressure. The method comprises the steps that a to-be-composited tube 1, a to-be-composited tube 2, a small-size pvc tube 3-1 and a large-size pvc tube 3-2 are coaxially arranged from inside to outside, the space between the pvc tube 3-1 and the pvc tube 3-2 is filled with an explosive and a detonator, and an explosive device is formed; the two ends of a gap between the to-be-composited tube 1 and the to-be-composited tube 2 is sealed by sealing strips, vacuumizing is carried out, and a vacuum gap environment is constructed; the space among the to-be-composited tube 2, the explosive device and the to-be-composited tube 3 is filled with water to construct a water environment; and the explosive device is detonated to weld and combine the to-be-composited tubes, and the high-quality explosive composite tube is obtained. According to the method for preparing the explosive composite tube in the local vacuum environment through the water pressure, the phenomenon that in a traditional preparation method, the bonding interface of composite tubes is possibly melted in a large area is effectively eradicated; the problem that thin-wall tubes cannot be machined through a traditional method is solved; and sizes of to-be-composited tubes can be selected more freely.

Description

technical field [0001] The invention belongs to the field of explosive welding and relates to a method for preparing explosive composite pipes in a partial vacuum environment by using water pressure. Background technique [0002] Bimetallic composite pipe is a high-quality composite material widely used in aerospace, petrochemical, mineral refining and other fields. It not only has the advantages of high strength, good ductility, and strong corrosion resistance, but also ensures the original The physical and chemical properties of metal materials remain unchanged. Explosive welding uses the high pressure generated by explosive explosion to metallurgically bond several metals. It is a solid-state welding process commonly used in the production of bimetallic composite materials. Explosive welding is widely used in the manufacturing industry. It is characterized by relatively low production costs and is capable of producing a wide variety of bimetallic and even multimetal comp...
