BW-ZM型直埋内压式波纹补偿器

BW-ZM directly-buried inner-pressure corrugated compensator

Page40

BM-ZM型直埋内压式波纹补偿器由波纹管、导向环、外套筒和法兰（接管）组成。导向环在外套筒的保护下实现自由伸缩补偿，可直接埋于地下，适用于热力管道等冷热变形的补偿。

BW-ZM direct buried inner pressure corrugated compensator is made up of bellows, guide loop, outer sleeve and flange(connecting pipe).The guide loop under the protection of the outer sleeve can realize flexing freely, which can be directly buried under the ground and applied in the distortion compensation of heat pipeline.
