Regarding the replacement of Hastelloy B3 tubular heat exchangers?
Thread Content
Our company used shell-and-tube heat exchangers in the past, with tubes made of Hastelloy B3. After 6 years of use, several of these tubes corroded and started leaking. We now want to order Hastelloy B3 tubes from a company in the United States, but the lead time for ordering is 42 weeks. Production cannot be delayed; 316L pipes can be used as a temporary substitute, but they will only last for 2 months. Our materials are highly corrosive at high temperatures. I now want to use a new type of enamel-coated plate condenser. Dear sea friends, who has used this new type of heat exchanger? Or can anyone suggest some other alternative methods? Thank you! !
The new type of lined enamel-plate condenser can withstand high temperatures and corrosion; however, the temperature of the medium should not change too drastically! ! ! ! !
Could you tell me exactly what the operating conditions are for the materials, as well as what the specifications of the pipes are? We handle many special materials, so let’s see if we can find what you need in stock
60% sulfates, 140°C – only Hastelloy B3 material can be used.
Is the pressure high? What about graphite if it’s not that high?
316L composite heat exchange tubes lined with PTFE (Teflon)
I’m not sure what the diameter of the owner’s pipes is; silicon carbide pipes could be used
Are you still using those tubes? I’m currently working with this nickel-based material
