How to solve the problem of impermeable stainless steel welded pipe? 2018-05-26 When the stainless steel welded pipe appears impermeable, the main reason is that the heating time is not enough. Under normal circumstances, different pipe materials, different models and specifications of stainless steel welded pipes, the welding heating time is specified at the factory, but the heating time is set when the ambient temperature is 20 ℃ and there is breeze. When the ambient temperature is low When the temperature is 10°C and the wind is strong, if the heating and welding are performed according to the set heating time, the surface after welding is not much different from the normal welding, but in fact there is no penetration. In this case, how should we solve it? When the construction environment is lower than 10°C and the wind is high, the heating time should be adjusted appropriately according to the different types and specifications of the pipe.
