The use of spiral steel pipe is relatively high and its application scope is very wide. How to choose spiral steel pipe before choosing it should pay attention to its quality.
 
The first method is a more professional testing method, that is, through the strength of the pressure vessel to be tested. Usually, we use atmospheric pressure and water pressure to test, so that we can test the working state of spiral pipe in the pressure working environment, and also detect the sealing of spiral pipe. Generally, we use atmospheric pressure to test, because this kind of safety is relatively high. If we pass the steam pressure test, then we need to remove the spiral pipe after water, which is too troublesome.
 
The second method is also relatively simple, that is, by observing the surface. Welding and dimension problems in spiral pipe can be found by naked eye. If necessary, standard samples can be used to compare with products to find out the problems. Generally speaking, the regular steel pipe company is relatively perfect in production, on the other hand, to defeat the metal pipe, if the sound is very crisp, the echo is not very dirty, then the name is the latest choice of steel pipe, rather than scrap recycling.
 
These two methods are commonly used, we can choose a way to test, the safer way is the best formal manufacturer, can reduce the use of abuse process.
