The reason why the surface brightness of stainless steel heat exchange tube is not uniform huatian Special material to share with you!!

The reason for the uneven surface brightness of the stainless steel heat exchange tube, this problem, today Huatian Special wood and you to understand:

Zhejiang Huatian stainless steel Manufacturing Co., LTD., located in No. 1 Jiangnan Road, Songyang Jiangnan Industrial Park, Lishui City, Zhejiang Province, is a professional engaged in stainless steel research and development, production, processing, sales as one of the comprehensive private enterprises.

The company is a professional production of stainless steel heat exchanger tube enterprises, the company has pressure pipe components manufacturing license (A1) class, license number: TS2710O08-2022. Zhejiang Lishui famous brand products, Certificate no. : 2017 (work) -043. Fully qualified!

According to relevant data, there are two reasons:

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 00Cr19Ni1 (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 exchange tube, and then make the production of stainless steel heat exchange tube gloss 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.

Extension of the problem: what is stainless steel heat exchange tube?

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.
