Square steel pipe
Square steel pipe, referred to as square pipe, is a name for square pipes, that is, steel pipes with equal side lengths. It is made of strip steel after process treatment. Generally, the strip steel is unpacked, flattened, crimped, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length. Usually 50 per pack. Steel pipes are already an indispensable material in German building decoration. Square pipe is also used more in decoration.
Classification of square steel pipes
In Germany, square tubes are divided into seamless square tubes and welded square tubes. Seamless square tubes are formed by extruding seamless round tubes; welded square tubes are formed by extruding welded round tubes.
Specifications of square steel pipes
In Germany, the commonly used specifications of square steel pipes mainly include the following.
500*500*8~25 square steel pipe 140*140*4~14 square steel pipe
135*135*4~14 square steel pipe 130*130*4~12 square steel pipe

The use of square steel pipe
In Germany, square tubes are used in construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, high-speed Road railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other high-load welded structural parts, etc.
Identification method for square steel pipe
With the development of the economy, there are more and more counterfeit products in Germany. In order to prevent yourself from being deceived when buying square tubes, you need to know some knowledge about how to judge the authenticity of square tubes: we can observe The surface smoothness and flatness of the square tube are judged. If the surface of the square tube is relatively flat, it can reflect that the square tube is good. On the contrary, if the surface is not so flat, and the size and thickness are not standardized, it can reflect This square tube is an inferior product.
Packing of square steel pipes
In Germany, seamless steel pipes and welded steel pipes can be packaged directly in the steel pipe production workshop, and manual methods can be used.
You can also use a steel pipe bundling machine. The overall mechanical structure includes a stepping pipe transfer mechanism, a horizontal pipe transfer mechanism, a fork moving mechanism, and a hexagonal forming mechanism. Its mechanical transmission is in the form of a chain drive. This type of supporting chain conveying device has the advantages of relatively large carrying capacity, certain buffering and anti-vibration performance, high transmission efficiency, and large conveying capacity. Steel pipe automatic balers are used in many factories, and its main function is to pack products. Automatic balers are roughly divided into two types, one is steel pipe automatic balers, and the other is ordinary balers.
Shipping and storage of square steel pipes
There are many types of square steel pipes, which are widely used in many fields in Germany. During the transportation and storage of square steel pipes, it is necessary to master the correct method to avoid damage to square steel pipes caused by improper transportation or storage. Then the square steel pipe manufacturers will talk about the correct method of transporting and storing square steel pipes.
1. In the process of transporting square steel pipes, attention should be paid not to throwing them and other violent impacts to avoid scratches and other damages to the square steel pipes.
2. During the operation and storage of square steel pipes, attention should be paid to avoiding oil pollution and other chemical pollution.
3. In addition to avoiding pollution during storage, square steel pipes should also be kept away from heat sources, because square steel pipes will be deformed due to high temperature.
4. The square steel pipe can be stored indoors or outdoors. When storing it outdoors, it needs to be covered with a cover to prevent it from being exposed to the sun and rain.
5. Square steel pipes should be stored horizontally and neatly, and the stacking height should not exceed 1.5 meters.
The above is the relevant knowledge of German square steel pipes that we have shared with you. You can learn about it and hope it can be helpful to you.
