A manufacturing process of explosive composite pipe

Abstract

The invention discloses an explosive cladding tube manufacturing process. The explosive cladding tube manufacturing process includes the following operations that a tube needing cladding is prepared, wherein the tube at least comprises a cladding tube and a lining tube; a first explosive fiber spirally and evenly winds the cladding tube; after the required explosive amount is wound, the first explosive fiber is loosened, so that gaps of the preset distance are kept between the first explosive fiber and the outer wall of the cladding tube; a second explosive fiber is inserted into the lining tube and fixed by a plug with a hole; the first explosive fiber and the second explosive fiber are connected to a same detonator to form a whole device, the whole device is placed in water storage equipment, and a part needing cladding is placed under water; eventually, detonation is conducted. Actual experimental results show that the explosive cladding method of a long tube and a superlong tube is innovative and has innovativeness in multiple aspects and outstanding advantages.

Description

technical field [0001] The invention relates to the field of metal composite technology, in particular to a manufacturing process of an explosive composite pipe. Background technique [0002] Corrosion is a common and serious problem that pervades various industries and greatly affects the production and development of chemical, petroleum, mechanical and military industries. The loss caused by corrosion is quite astonishing, it is several trillion yuan every year, and it is increasing year by year, especially in the petrochemical industry, which uses a large number of pipelines. The harsh environment makes corrosion more serious than other fields, especially the offshore oil and gas field. Therefore, the anticorrosion of petrochemical pipelines is of great significance to the healthy development of the petrochemical industry and the closely related national economy. [0003] Although more and more new materials are used with the development of material science, steel pipes ...

AI Technical Summary

Problems solved by technology

[0005] 1. Each compound will cause certain damage to the device, sometimes even direct damage, which will undoubtedly increase the cost and is not conducive to industrial production;

[0006] 2. Due to the direct contact between the explosive and the pipe wall, it is very difficult to control the amount of explosive. If the amount of explosive is too large, it will cause damage to the pipe wall, and if it is too small, the welding will fail;

[0007] 3. The utilization rate of explosive energy is not very high, which will not only increase the cost but also cause secondary disasters;

[0008] 4. It is not suitable for the compounding of long tubes, and it is easy to cause large deformation of long tubes
