Metal Pall Ring Sales Case:
I have a korean customer named Mr. J. He works as a chemical
engineer in a corporation laboratory. Last time he contacted me to
see if we could provide 16mm pall rings in SS316, with certificates
for the material. Also he need the column random packing in a
hurry. Surely no problem! We have stock of such packing for
immediate delivery. It is convenient to send the pall rings by
SF-express to Republic of Korea, especially when the customers have
a SF account.
