Problems solved by technology

[0005] The purpose of the present invention is to solve the existing problem in the prior art that the existing bimetallic composite pipes have relatively general corrosion resistance during actual use, so that it is easy to cause the composite pipes to fail to guarantee long-term use. Due to its large volume, the composite pipe is very laborious to install, and the assembly and welding process is difficult, so that the installation efficiency is reduced. A corrosion-resistant large-diameter bimetallic metallurgical composite pipe is proposed.

Abstract

The invention provides a corrosion-resistant large-diameter bimetal metallurgy composite pipe, and relates to the technical field of bimetal composite pipes. The corrosion-resistant large-diameter bimetal metallurgy composite pipe comprises a composite pipeline and an auxiliary pipe, the top of the composite pipeline is fixedly connected with the auxiliary pipe, the inner wall of the composite pipeline is fixedly connected with a fluorine-lined pipe, a corrosion-resistant sealing ring is fixedly connected between the inner wall of the composite pipeline and the outer wall of the fluorine-lined pipe, and a butt joint plate is fixedly installed at one end of the composite pipeline. The fluorine-lined pipe with the thickness being 8 mm is installed on the inner wall of the composite pipeline, and the corrosion-resistant sealing ring is installed between the connecting positions of the composite pipeline and the fluorine-lined pipe, so that in the using process after actual installation, effective corrosion resistance can be further achieved on the pipeline through the inner fluorine-lined pipe, in addition, the pipe also has the effects of pressure resistance and high-and-low-temperature resistance, the use range is increased, and the durability is effectively improved; besides, the corrosion-resistant sealing ring is arranged in the connecting positions, so that the conditions of internal water seepage and the like can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of bimetallic composite pipes, in particular to a corrosion-resistant large-diameter bimetallic metallurgical composite pipe. Background technique [0002] Bimetallic composite pipes have high carbon content, impact resistance, low thermal expansion rate, pressure and high temperature resistance, mature installation, and complete specifications; bimetallic composite pipes produced by many manufacturers are widely used in oil fields, chemicals, electric power and other industrial fields , its scope of application is becoming wider and wider, and the economic, environmental and social benefits it brings are more obvious. [0003] In the prior art, for example, the Chinese Patent No.: CN201520642617.3 "a kind of bimetallic composite pipe", the joint surface of the liner pipe and the base pipe is composed of mechanical joint sections and metallurgical joint sections intermittently distributed, There is at least...
