Despi­te weig­hing just 5 tons, this stain­less steel heat exch­an­ger con­sists of 840 tubes . More than 1,700 pres­su­re part welds were requi­red, with 100% X‑ray inspec­tion. Other spe­cial requi­re­ments included a grea­ter mini­mum wall thic­k­ness, very clo­se tube pitch, num­e­rous inspec­tion ope­nings, accep­tance in accordance with ASME and PED, and addi­tio­nal pres­su­re and leaka­ge tests for the pres­su­re part and the casing.
Excel­lent com­mu­ni­ca­ti­on and coope­ra­ti­on was key to the suc­cess of this com­plex project!
