Causes of damage to steel expanders

Causes of damage to steel expanders
Steel expander is by far the most widely used pipe fitting in pipeline engineering. Its material is generally carbon steel. Its sturdy structure allows it to invade other pipe fittings, so that steel expanders can be used in these fittings. very well. However, in some special cases, steel expanders may sometimes be damaged. There are two general reasons for this phenomenon.
 
1. Environmental problems, this problem usually occurs in cold areas. As we said above, steel expanders are made of carbon steel, sometimes they are also made of ordinary steel. Its raw material is metal, so when it encounters cold weather or installed in a colder environment, this material will become more brittle. Although the hardness will not become worse, but its toughness is not so good. It will be more brittle. If the expansion joint is subjected to external forces at this time, it will appear cracks and other unqualified phenomena, and then the expansion joint can not work, the impact on the whole pipe is more serious. For this situation, we recommend that you specify the installation area in advance when you buy, so that we can replace the expansion joint of special materials.
 
2. Man-made problems, this problem generally occurs in the installation process of goods lifted by the aircraft car time period. This problem generally belongs to the damage caused by improper work of the installer. In the installation process, sometimes need large machinery and equipment to complete the work. At this time, if the installer does not operate properly, the telescope will collide with external objects. The expansion device can be damaged by the installation, or caused by excessive operating force. These damages are caused by human beings, so please use high-tech installers when installing.
