Heating pipe why "short-lived"
Shell:
Welded and seamless
1, tube maximum working pressure can usually afford within 20 kg, which is used the most secure. ;
2, the seamless tube can withstand high pressure, the wall thickness will increase, which needs to design according to pressure.蘇州電加熱管、蘇州加熱管、蘇州電熱管

3, there are some seamed steel pipe seamless processing tube, it is to weld the annealing treatment, to eliminate the residual stress of the weld, the weld and base material, the pressure range of seamless tube and a basic. Also can consider to use.
4, there are also some of the tube with integral heating after drawing or mandrel rolling seamless steel pipe, mainly to small size, this kind of tube only in appearance of seamless pipe, in fact is not very good, pay attention to oh!
If you use a pressure higher than 20 kg is seamed tube or by using fourth kinds of imitation seamless pipe, will likely heating medium pipe cause a short circuit caused tube bursting.
