Why does the stainless steel heat exchange tube have some dark light, what is the reason?? Huatian Stainless steel professional production of stainless steel heat exchange tube manufacturers, for you to introduce:

Stainless steel heat exchange tube, as everybody knows, it is a rapid device that would transmit the heat from one point to another point, and almost no heat loss, so it is called heat transfer superconductor, has the very high thermal conductivity and good temperature resistance, so normally, be used in the stainless steel heat exchanger, used as one of the components of the stainless steel heat exchanger. The commonly used materials of heat exchange tube are carbon steel, low alloy steel, stainless steel, copper, copper nickel alloy, aluminum alloy, titanium, etc., among them, the most commonly used heat exchange tube on the market is stainless steel tube. The observation of the stainless steel heat exchange tube, directly is to see the gloss of its surface, we see the stainless steel heat exchange tube will find that the same type of stainless steel tube why some look bright, some appear dark? Below, Huatian stainless steel to tell you, what are the reasons that will affect the luster of the stainless steel heat exchange tube.

The reasons affecting the gloss of the stainless steel heat exchange tube may be the following ways:

1. Raw materials

(1) Good raw materials can produce good products, while inferior raw materials can produce inferior products. Good steel strip element content is stable, the production of stainless steel heat exchange tube gloss is very high;

And inferior steel belt, the production of stainless steel heat exchange tube element content is not stable, so the gloss of stainless steel heat exchange tube will be very dark.

(2) The material of raw materials. Common stainless steel heat exchange tube material is 0Cr18Ni9 (304) stainless steel and 00Cr19Ni10 (304L) stainless steel these two widely used austenitic stainless steel.

Hardness is too low, polishing is not easy to shine, and hardness is too low, in deep tensile surface prone to orange peel phenomenon, thus affecting gloss; Stainless steel with high hardness, its polishing effect is good, glossiness is relatively good.

In addition, stainless steel tube thickness between 0.52-1.1 mm, polishing out of the effect is good, because the thin and thick polishing strength is more difficult to control, the strength of the thin tube will be deformed, the strength of the small thick pipe polishing strength is not up to.

(3) raw material surface defects, such as scratches, pitting, scratching, trachoma, etc., the emergence of these defects, will directly affect the production process of stainless steel heat transfer, and then make the production of stainless steel heat transfer tube gloss

Will be on the low side.

2. Manufacturing process. The polishing link in the production process has a direct effect on the gloss of the stainless steel heat exchange tube, that is to say, if the stainless steel heat exchange tube is polished, because of external factors

(temperature, humidity) and other factors, making the polishing treatment of stainless steel heat exchange tube problems, the result is the production of stainless steel heat exchange tube glossiness is not high, the surface is dim.
