自由直埋式管道已普遍采用波纹补偿器，由于土壤中含有各种腐蚀介质特别容易使补偿器的主要部件波纹管出现孔蚀、应力腐蚀现象，结果波纹管在远没达到设计寿命时即发生泄漏或开裂，造成不应有的损失，本文介绍了针对直埋式波纹补偿器的特点所设计的几种 防腐蚀结构，这些结构已获得了国家专利。

Abstract:Bellows Expansion Joints are widely used in the directly buried pipeline.Because in soil exist many kinds of corrosive media,which make the main component of the expansion joint-bellows to be subjected to hole corrosion and stress corrosion,so leakage and crack has appeared on the bellows prior to reaching its designed life far away.That causes undeserved losses.This paper introduces seve ral anticorrosive constructions basead on the characteristic of directly buried expansion joiots.All of these constructions are patent.
