Difference between pipe theoretical weight and actual weight

Steel pipes such as Tianjin welded erw steel pipe have very extensive application in industrial production. Although the material of welded steel pipe in terms of hardness is not sturdy as seamless steel tube, its price has more obvious advantages. We may often encounter such a problem that is steel pipe exist certain differences between the actual weight and the theory weight. Customers who do not understand the principle of pipe weight will be concerned about the steel pipe price. So does pipe weight will affect the welded steel pipe price? Now we can talk about more details about this topic.

Is there a big difference between the theoretical weight and the actual weight of welded steel pipe? Why are there differences in weight between the same welded steel tube specifications such as square tubing sizes? It is mainly affected by the following factors.
The thickness of steel tube wall is different.
Due to the impact of production batches and raw materials, even the same steel tubes with the same specifications will have a weight difference. Actually, when we purchase steel pipes, the steel pipe suppliers usually set steel pipe price according to the actual weight, which can guarantee the personal interest. Therefore, when buying steel pipes, we can choose steel pipes with uniform thickness depending on the actual needs and weigh them.

The material of steel pipe is different
Steel pipes can be welded by a variety of materials such as steel bars and steel plates, which can be converted into steel tubes through industrial processing. Steel tubes such as round steel pipe of the same specifications can also be made up of different raw materials. Therefore, due to the different welding materials, the weight of the steel tube will change.

The production process of steel pipe is different.
In the process of welding steel pipe, there are many kinds of production techniques such as the common argon arc welding, gas welding and so on. The weight of the steel tube will vary depending on the welding process. Some use welding rods for welding and the weight of the steel tube is heavier than the welding method using the electrode. In a word, steel pipe manufacturers should choose the suitable welding techniques and method that can determine steel pipe weight as well as steel pipe price.
