Difference between blasting purging and long purging
Thread Content
For pipes that have given consent, is it better to use 2.5MP burst purging or 2.5MP continuous purging? My question is this: since the overall pressure difference is 2.5 MP, which purge method will yield better results if steam consumption is not taken into account?
The blasting purge is too intense; it is recommended to use a pressure-reduction method for purging, which allows the pressure to be increased to over 3.0 MPa. Attention should be paid to temperature changes – purging at 2.5 MPa actually constitutes a pressure-equalization method, with emphasis on the steam flow rate
