How to choose when buying rectangular tubes？

When choosing a rectangular tube, there are several aspects to consider to get the most suitable product.

First of all, from the perspective of product structure, rectangular tubes usually consist of a tube body and two end plates. The tube body is rectangular and made of sheet metal. The end plates are round and welded to the pipe body to maintain the shape and strength of the pipe body. When selecting a rectangular tube, you need to consider its length, width, height, wall thickness and other parameters. These parameters will determine the load-bearing capacity and stability of the rectangular tube.



Secondly, when choosing a rectangular tube, you need to consider the quality and service life of the product. You can consider the following aspects:

1. Production process: If you choose a regular rectangular tube manufacturer, its production process will be more stable and reliable, and it will have higher production efficiency.
2. Raw materials: Choosing high-quality raw materials can ensure the quality and stability of the rectangular tube. For example, you can choose rectangular tubes made of stainless steel plates, which have strong corrosion resistance and are suitable for various environments.
3. End plate sealing: Good end plate sealing ensures the sealing of the rectangular tube, allowing it to withstand higher pressures.
4. Installation method: Considering the installation method is also one of the factors that need to be considered when choosing rectangular tubes.

The main classification and application areas of rectangular tubes:

Rectangular tube is a kind of tube with rectangular cross-section, which can be divided into several types such as welded rectangular tube, seamless rectangular tube and color-coated rectangular tube. Among them, welded rectangular pipe is the most commonly used one and is mainly used in construction, machinery, aviation, shipbuilding and other fields.

Seamless rectangular tubes have the advantages of high strength, good corrosion resistance, and strong sealing performance. They are mainly used in petrochemical, fertilizer, pharmaceutical, medical equipment and other fields. They can also be used as materials for automobile parts.

Color-coated rectangular tubes are more beautiful in appearance and can be customized according to customer needs. They are mainly used in construction, daily necessities, furniture and other fields.

Key factors and considerations for selection:

1. Determine the material and specifications of the rectangular tube according to the application scenario and requirements. Common standard materials include EN 10210, EN 10219, ASTM A500, etc. The specifications can be determined according to the use requirements.
2. Select the appropriate type of rectangular tube according to the application scenario. For example, in high temperature, high pressure, and highly corrosive environments, seamless rectangular tubes with good corrosion resistance should be selected.
3. Select a rectangular tube manufacturer based on budget and quality requirements. You should choose manufacturers with good reputation, exquisite production technology and stable product quality.
4. When selecting rectangular tubes, attention should be paid to the stability of the material and various indicators, and not just the price factor.
5. When purchasing rectangular tubes, national standards and quality standards should be strictly implemented, and necessary random inspections and other tests should be conducted to ensure that the purchased rectangular tubes meet the usage requirements.

Finally, rectangular tubes have the following advantages and usage scenarios:

1. It has the advantages of simple structure, beautiful appearance and easy cleaning.
2. It is widely used in petroleum, chemical industry, medicine, light industry, machinery, construction and other industries.
3. It can be used in various pipeline systems, such as liquid transportation in petroleum and chemical pipelines, and gas transportation in gas pipelines.

Conclusion:

As an important construction and mechanical material, rectangular tubes are widely used in various fields. When selecting, you need to consider multiple factors such as material, specifications, type, manufacturer, price, etc., and you need to inspect them strictly in accordance with national standards and quality standards to ensure that the purchased rectangular tube meets the usage requirements.
