Problems solved by technology

Due to the working characteristics of the ironmaking blast furnace, molten iron slag is often splashed. Once the splashed high-temperature slag passes through the mesh of the metal mesh sleeve outside the metal corrugated hose and falls on the surface of the metal corrugated hose It is easy to cause melting holes on the surface of the thin-walled metal corrugated hose
In addition: Since the steelmaking and continuous casting machine works in an environment with a high temperature of 700° to 800°, when the metal corrugated hose is used in this high temperature environment, the elements contained in it, such as nickel, chromium, and titanium, are easily damaged at high temperatures. High temperature corrosion and oxidation are formed, and the metal corrugated hose is easy to crack
Therefore, the disadvantage of the above-mentioned metal corrugated hose is: the service life is short

Embodiment Construction

[0013] figure 1 As shown, a metal hose for conveying fluid according to the present invention is composed of a metal corrugated hose 2 with connecting joints 1 at both ends, and a metal hose net sleeve is sheathed on the outer surface of the metal corrugated hose 2 4. The two ends of the metal hose mesh sleeve 4 are respectively provided with a joint sheath 3 fixedly connected with the joint 1 and a metal protective tube 7 fixedly connected with the joint 1 is covered on the outer surface of the metal hose mesh sleeve 4 . The metal protective pipe 7 can prevent the high-temperature slag splashed by the blast furnace from falling directly on the metal corrugated hose 2 , which prolongs the service life of the metal corrugated hose 2 . The metal protective pipe 7 is composed of a metal pipe 6 and an annular baffle 8 welded at both ends of the metal pipe 6 to fix the metal pipe 6. The annular baffle of the metal protective pipe is fixedly connected with the joint of the metal co...

Abstract

A flexible metallic pipe for delivering fluid is composed of a corrugated metallic pipe, a reticular jacket, two end jointer, and metallic protecting pipe connected to said end jointer and consisting of metal pipe and ring barrier plate.

Description

technical field [0001] The invention relates to a metal pipe, in particular to a metal hose for transporting liquid and gas. Background technique [0002] In order to transport liquid or gas in metallurgical factories, metal corrugated hose with a metal hose net sleeve on the outer surface and a wall thickness of 0.2-0.3mm inside is mostly used, and the two ends are connected by joints. Due to the working characteristics of the ironmaking blast furnace, molten iron slag is often splashed. Once the splashed high-temperature slag passes through the mesh of the metal mesh sleeve outside the metal corrugated hose and falls on the surface of the metal corrugated hose It is easy to cause melting holes on the surface of the thin-walled metal corrugated hose. In addition: Since the steelmaking and continuous casting machine works in an environment with a high temperature of 700° to 800°, when the metal corrugated hose is used in this high temperature environment, the elements conta...
