The invention relates to an efficient anti-scaling condensation pipe. A thin-wall circular pipe is made of stainless steel, straight pipes with equal diameter are at two ends, a corrugated pipe is on the middle part, and the outer surface of the corrugated pipe is evenly distributed with raised pyramid lug bosses. The condensation pipe has the following advantages that: because fluid in the corrugated pipe disturbs intensively at low flow rate to generate turbulent flow which has complete flushing function on the pipe wall, the easy-scaling problem of the condensation pipe is well solved; simultaneously, due to surface curvature change and axial extension change of the corrugated pipe caused by temperature and larger linear expansibility difference of the stainless steel pipe wall and the scale, the scale is easy to fall off, self cleaning of the pipe is achieved, and the scale removing problem of the condensation pipe is well solved; moreover, the pyramid lug bosses on the outer surface of the corrugated pipe increase the heat exchange area and puncture condensate membranes, so drops are easy to form and drop quickly along a wave crest, and the vapor-liquid conversion time is quickened. The pipe has light weight, high strength and quick heat transfer, and is superior to the prior structural copper pipe in economic benefit, service life and the like.
