What is the reason for uneven surface luster of stainless steel heat exchange tube? This problem, xiaobian view information sorted out a few content:

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 pipe, 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 glossiness will be low.

2. Manufacturing process.

The polishing process in the process of production, has direct influence on the gloss of the stainless steel heat exchange tube, that is to say, if on the heat exchange tube of stainless steel polishing processing, because of the external factors (temperature, humidity), the influence of such factors as the heat exchange tube of stainless steel polishing processing problems, the result is to produce stainless steel heat exchange tube gloss is not high, the surface is bleak.
