Why the seamless steel pipe cracks?
When talking with customers, our company workers often hears such a question: will the seamless steel pipe crack? It turned out that in their previous procurement, they often encountered the crack problem of the purchased steel pipes. The product quality had serious problems, resulting in significant economic losses to the company. In view of the seamless steel pipe cracking problem, We will give you the analysis of the main reasons or factors of the cracking of seamless steel pipes.
The fundamental reasons are as follows:
1. Raw materials
Some seamless steel pipes manufacturers, they choose small steel mills producing round steel to carry on the processing in order to save costs, but these small steel mills production of round steel will contain many impurities, such as bubbles. Using the round steel production of seamless steel pipes inside can have a sandwich, porosity, etc. After the late processing, it can produce the problem of cracks.
2. Heat treatment temperature control is not in place
Some manufacturers are not rich in production experience, and it is impossible to guarantee whether the heat treatment of seamless steel pipes is in place by judging the heating temperature and duration only by the experience of workshop workers. However, heat treatment will change the mechanical properties of seamless steel pipes. General manufacturers do not have testing equipment to judge whether the seamless steel pipe has reached the performance indicators required by customers.
3. The alignment
In the straightening process, too much straightening strength will also cause internal damage and cracks in the steel pipe. Without flaw detection in the later stage, the steel pipe is directly packed and shipped, which is also the reason for the steel pipe cracking in the later stage.
4. Drawing
If the drawing deformation is too large, it will also form steel pipe cracks, resulting in steel pipe cracking in the process of late processing.
Then, how to use seamless steel pipes correctly? Here are the method guide for the correct use of seamless steel pipes.
The seamless steel pipe is a very high degree of stability of a transport pipe. It has a relatively high reliability and a long service life. Now, the pipe material produced by brand-new technology is mainly composed of two parts. One is the sensor that directly touches the medium transported inside the pipe material and the upper end has a signal converter.
Now the common seamless steel pipe is based on the principle of electromagnetic induction to work. For customers, customers buy seamless steel pipes, the pipe should be connected with the pipe first before using such delivery pipe. Pipes connection methods exist in all kinds of different ways.
The first is the use of flange connection. This method is relatively traditional. The seamless steel pipe at both ends can be connected. When the flange and pipe connect, the flange at both ends and the bolt used on the pipe can be fixed.
About the selection of this device method, basically it can be a one-way device, and the sensor volume limit of this connection method pipe should be smaller. Then, this kind of pipes is only suitable for use in some relatively small volume. Another method of installing seamless steel pipes is to add joints.
