The Complete Guide to Stainless Steel Tube

What is stainless steel tube?
Stainless steel tube is a hollow, multi-purpose pipe material that is widely used in various fields. Because it has a hollow section and can be used for a long time in harsh environments such as acid, alkali, and salt without corrosion, it is most suitable for transportation pipelines for liquids, gases, and solids. And compared with round steel of the same weight, stainless steel tubes have larger section coefficients and greater bending and torsional strength. During its use, the pipes need to be cleaned and inspected regularly to keep them clean and functioning properly.

Stainless Steel Tube Types

(1) According to the production method, stainless steel tubes are divided into seamless tube and welded tube. They can also be divided into stainless steel cold drawn tubes, hot rolled tubes, extruded tubes, spiral welded tubes, etc.

(2) According to material classification, it can be divided into austenitic stainless steel tube, ferritic stainless steel tube and martensitic stainless steel tube.

(3) According to the cross-sectional shape, it can be divided into stainless steel round tubes and special-shaped tubes.

(4) According to the classification of tube ends, they can be divided into stainless steel plain pipes and wire tubes.

(5) According to the classification, it can be divided into stainless steel oil well tubes, boiler tubes, chemical tubes, ship tubes, etc.

Stainless Steel Tube Performance

  • High-temperature corrosion resistance: Stainless steel tube contain chromium and can form a dense chromium oxide film, making them highly corrosion-resistant, able to resist erosion by a variety of chemicals, and can still maintain their properties at high temperatures. It has strength and stability and is not easily deformed or oxidized.
  • High strength: It has high tensile strength, yield strength and impact toughness, and is able to adapt to complex working environments and high-pressure working conditions.
  • Good weldability and processing performance: It can be welded by a variety of methods and is easily processed into pipes of various shapes and sizes, which can meet the needs of different engineering projects.
  • Service life and hygienic safety: Stainless steel tube has good durability and low maintenance costs. They will not produce harmful substances when in contact with food, drinking water, etc., but they require regular cleaning and maintenance to maintain their surface finish, durability and corrosion properties.

Stainless Steel Tube Application

Stainless steel tube is widely used in machinery manufacturing, oil and gas, chemical industry, transportation, medical care, food, building structures, energy, electric power, metallurgy and other fields. It is usually used in various fields to transport oil, natural gas, food, water, gases and liquids, etc.
