Abstract
The invention relates to a novel bimetal compound pipeline with high pressure resistance and high corrosion resistance. The outer layer consists of a seamless steel pipe or an alloy steel pipe and the like, and the inner layer consists of a stainless steel pipe or corrosion-resistant alloy materials, such as copper, titanium or nickel and the like. The pipeline adopts the processing technology of double technology of a diameter shrinking method and software elasticity inner-expanding technology and is compactly compounded with zero clearance. The pipeline solves the problem that the linear expansion of the bimetal at a high temperature is poor, improves the corrosion resistance of the pipeline and prolongs the service life of the pipeline on the basis of ensuring all the performances of the prior base pipes, and has low cost. The pipeline better solves the problem that a medium in crude oil and crude gas influences the corrosion index of the transferring pipelines and obtains good use effect during use.
