 Physical and chemical properties:

1. Physical properties

density: The density of stainless steel pipes is generally between 7.7 – 8.0 g/cm3, and different alloy compositions will make the density slightly different.

Hardness: Moderate hardness, can withstand a certain external force, such as in the building structure can support a certain weight, to prevent easy deformation. Hardness can be changed by processing, like cold working can improve surface hardness. Strength: It has high tensile strength and compressive strength, can withstand tensile and extrusion without breaking, and plays a key role in the pipeline transportation of high-pressure liquids or gases.

Toughness: It has good toughness and will not break easily when subjected to impact, bending, etc. For example, in some mechanical connection pipes with vibration environment, it can be kept intact. Thermal Conductivity: The thermal conductivity is higher than that of general insulators, but lower than that of metals such as copper and aluminum. In a heat exchange device, it can conduct heat, but the efficiency is lower than that of some pure metal tubes.

Thermal Expansion Coefficient: The thermal expansion coefficient is relatively small. When the temperature changes, the pipe size changes less, which can reduce the risk of pipe damage caused by thermal expansion and contraction.

Magnetic: Some stainless steel pipes are magnetic, and some are not. Magnetic or not plays an important role in special application scenarios such as electronic equipment and magnetic separation.

Appearance and Gloss: The surface is smooth and has a metallic luster. Different appearance effects can be obtained through different surface treatments. It can add beauty when used for decoration. Ductile: It has ductility and can be bent and stretched into various shapes, which is convenient for processing into various complex pipe systems and pipe fittings.

2. Chemical properties,

corrosion resistance: It contains chromium and other alloying elements, forming a dense chromium oxide protective film on the surface, which can resist oxygen, moisture, sulfur dioxide and other corrosive media in the atmosphere, and can also withstand the corrosion of many chemical substances, such as acid, alkali, salt solution.

Oxidation resistance: In high temperature environments, stainless steel pipes can still maintain good oxidation resistance. This is because alloy elements form a stable oxide layer on the surface, preventing oxygen from further reacting with the metal matrix, so that it can be used for a long time in high temperature industrial equipment. Chemical stability: Stainless steel pipes remain stable in most chemical environments and will not react violently with common chemicals. They ensure the safe transportation of various media in food, medical, chemical and other industries.
