1. What is a stainless steel tube/pipe?

Stainless steel classification: Martensitic Stainless Steel, Duplex Steel, Ferrite, Austenitic Stainless Steel.

The chemical composition of stainless steel pipes is mainly composed of five elements: carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S). Among them, stainless steel pipes containing manganese and silicon can improve the deoxidation effect and mechanical properties of steel, while those containing sulfur and phosphorus are harmful impurities, and their content should be limited as much as possible.

Stainless steel pipe is a type of hollow, long, round steel that is mostly used for mechanical structural elements and industrial transportation pipes in the petroleum, chemical, medical, food, light industrial, and instrumentation industries. An essential item in the steel industry, stainless steel pipe has a low cost per cross-sectional area.

It typically makes up between 8% and 16% of all steel. It has several uses for the national economy and is a form of saving in and of itself. High-efficiency steel has an essential role in the oil drilling, smelting, and transportation industries. This steel has an economical cross-section.

Numerous different stainless steel pipes are also needed in the production of boilers, medical equipment, furniture, and bicycles, as well as in the chemical, construction, mechanical, aerospace, and automotive industries. Because they feature a hollow part, stainless steel pipes can be used to carry liquids, gases, and solids.

Steel pipes are also employed in many mechanical and architectural projects because they have strong bending and torsional strength and a big section coefficient when compared to round steel of the same weight. substance of importance. The section modulus of structures and parts constructed of stainless steel tubes is higher than that of solid parts.

3. Mechanical properties of stainless steel tube/pipe

Yield point (σs)

When the steel or sample is stretched, when the stress exceeds the elastic limit, even if the stress no longer increases, the steel or sample continues to undergo significant plastic deformation. This phenomenon is called yielding, and the minimum stress value when yielding occurs is for the yield point. Assume Ps is the external force at the yield point s, Fo is the cross-sectional area of the sample, then the yield point σs = Ps/Fo (MPa).

Yield strength (σ0.2)

The yield point of some metal materials is extremely unclear and difficult to measure. Therefore, in order to measure the yield characteristics of the material, the stress when the permanent residual plastic deformation is equal to a certain value (usually 0.2% of the original length) is specified, which is called the condition. Yield strength or simply yield strength σ0.2.

Tensile strength (σb)

The maximum stress value reached by the material from the beginning to the time of fracture during the stretching process. It indicates the steel's ability to resist fracture. Corresponding to tensile strength are compressive strength, flexural strength, etc. Assuming that Pb is the maximum tensile force reached before the material is broken, Fo is the cross-sectional area of the sample, then the tensile strength σb = Pb/Fo (MPa).

Elongation (δs)

After the material is pulled apart, the percentage of its plastic elongation length to the original sample length is called elongation or elongation.

Yield-strength ratio (σs/σb)

The ratio of the yield point (yield strength) of a material to its tensile strength is called the yield ratio. The larger the yield-strength ratio, the higher the reliability of structural parts. Generally, the yield-strength ratio of carbon steel is 0.6-0.65, and that of low-alloy structural steel is 0.65-0.75. Alloy structural steel is 0.84-0.86.


Hardness indicates a material's ability to resist hard objects pressing into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Commonly used hardness indicators include Brinell hardness, Rockwell hardness and Vickers hardness.

6. Applications and characteristics of stainless steel tube/pipe

Characteristics and applications of stainless steel tube/pipe

Because of their excellent mechanical qualities, superior wear resistance, and thin, dense layers of chromium-rich oxide on the surface, stainless steel pipes resist corrosion well in all types of water, including soft water, and even when used underground. resistant against corrosion.

Up to 30 meters per second of high-speed water erosion can be tolerated by stainless steel pipes. They are used in high-head power plants to divert stainless steel pipelines. Despite having a service life of more than 100 years, the water speed at the pipe mouth can reach more than 60 meters per second.

Stainless steel pipes have tensile strengths of more than 530 N/mm, which is twice as strong as galvanized pipes, three to four times as strong as copper pipes, and eight to ten times as strong as PPR pipes. Additionally, it is strong and pliable, both of which help conserve water.

Beautiful appearance, neat and trendy, 100 percent recyclable, good safety and hygiene performance, good temperature resistance, good thermal insulation performance, smooth inner wall with low water resistance, and can work safely for a long time at temperatures of -270°C to 400°C. Regardless of the temperature, whether it is high or low, no harmful substances will precipitate, and the material performance is quite stable.

Stainless steel waste also has great economic value, is safe and non-toxic, and has a thermal insulation performance that is 24 times better than copper pipes. This reduces heat energy loss, makes stainless steel pipes suitable for transporting hot water, does not pollute the environment, is green and environmentally friendly, and promotes sustainable development.

It preserves water quality pure and hygienic, is toxic, has no corrosion or exudation, no odor or turbidity issues, won't create secondary pollution to water quality, and hygienic safety is totally guaranteed.

In addition to providing excellent support, stainless steel pipes have the ability to carry liquids and gases across great distances, enhance industrial production efficiency, and enhance people's quality of life. Stainless steel pipes are affordable and useful. It is widely employed in life and is used to build infrastructure in many different industries.
