Stainless steel corrugated heat exchanger tube is a new type of high efficiency heat exchanger tube, which replaces straight tube. It has the advantages of strong corrosion resistance, longer service life, no pitting corrosion, low price and so on.
We are a professional supplier of boiler tubes and heat exchanger tubes. The corrugated heat exchanger tubes made of stainless steel are our main products.
Our stainless steel wave-knot heat exchanger tubes are made of straight bare-wall tubes by spinning. They are simple in structure, mature in manufacturing technology, easy to scale on the surface and high in heat transfer efficiency. Especially, the axial displacement caused by the change of medium temperature can be compensated by itself during operation. They are widely used in heat exchangers.
