Arrow Bulk Storage Tanks

Arrow Tank and Engineering has been fabricating LPG and NH3 storage vessels since 1960 in Cambridge, MN.  We are capable of building storage capacities in 18K, 30K, 45K, 60K, 90K, 120K and larger. Somewhat unique to Arrow Tank is our own state of the art post weld heat treatment (PWHT) oven onsite that not only serves our needs, but those of many other manufacturers in the United States and Canada.  With regard to LPG and NH3, PWHT is required for quenched and tempered (QT) LPG and NH3 transport vessels.  Storage vessels intended for NH3 service are also stress relieved in the oven.
