What Is The Special-Shaped Tubes?

Special-shaped tubes, as the name implies, refer to steel tubes with non-circular cross-sections. They come in many shapes, including square, rectangular, oval, etc. These characteristics make special-shaped tubes widely used in multiple industries.

1. Definition and Application of Special-Shaped Tubes

Special-shaped tubes are steel tubes with non-circular cross-sections. They can be square, rectangular, oval, etc. Due to their lightweight, high strength, corrosion resistance, and easy processing, special-shaped tubes are widely used in construction, machinery, automobile, aerospace, and other fields. 

In the field of construction, special-shaped tubes are often used to make decorative components such as doors and windows, railings, and stair handrails. In the field of machinery manufacturing, they are used to make machine tools, conveying equipment, agricultural machinery, etc. In the field of automobile manufacturing, special-shaped tubes are often used to make body structures, chassis, and other components.

2. Specifications and models of special-shaped tubes

Special-shaped tubes have various specifications and models to meet the needs of different industries and application scenarios:

(1) Square special-shaped tubes: Specifications range from 20\*20mm to 600\*600mm, thickness from 1.0mm to 35mm, mainly used in the fields of construction and machinery manufacturing.

(2) Rectangular special-shaped tubes: Specifications range from 20\*30mm to 600\*800mm, thickness from 1.0mm to 35mm, also widely used in the fields of construction, bridges, machinery manufacturing, etc.

(3) Oval special-shaped tubes: Specifications range from 20\*40mm to 400\*600mm, thickness from 1.0mm to 20mm, mainly used in the fields of construction and machinery manufacturing.

(4) Hexagonal special-shaped tubes: Specifications are 13-85mm, thickness is 1.5-8mm, mainly used in the fields of machinery manufacturing and automotive parts.

3. Material selection and related standards

The material selection of special-shaped tubes should be determined according to the use environment and requirements. Common materials include steel, stainless steel, aluminum, copper, etc. Steel is the most commonly used material due to its high strength, good corrosion resistance, and relatively low price. Stainless steel is suitable for special occasions such as food processing and medical equipment due to its excellent corrosion resistance. Aluminum is suitable for occasions that require a lightweight and beautiful appearance due to its lightweight and easy processing characteristics. Copper is suitable for occasions that require conductivity due to its good electrical conductivity.

When selecting the material of the special-shaped pipe, it is also necessary to consider the relevant standards and select the special-shaped pipe material that meets the relevant standards according to the specific use occasions and requirements.

4. Installation and maintenance precautions

The installation and maintenance of the special-shaped pipe must be carried out in strict accordance with the relevant standards and requirements to ensure the normal operation and safety of the pipeline system. During installation, it is necessary to ensure that the specifications and models of the special-shaped pipe match the pipeline system, check whether the surface is damaged or corroded, and ensure that the connection method is correct. Clean the inside of the special-shaped pipe before installation to prevent impurities from entering the pipeline system.

In terms of maintenance, it is necessary to regularly check whether the surface of the special-shaped pipe is corroded or deformed, clean the inside, and avoid accumulation from affecting the normal operation of the pipeline system. If the special-shaped pipe is found to be damaged or aged, it should be replaced in time. Anti-corrosion measures include spraying anti-corrosion treatment on the surface of the special-shaped pipe or selecting to use materials with anti-corrosion functions to manufacture the special-shaped pipe.
