Inquiry (采购产品): Finned Tubes for Heat Exchanger We use SA106B carbon steel tubes (Sch. 40 pipe) with carbon steel fins in our heat exchangers. The fins are helical and MIG welded to the pipe. Fins are also 1" at 5 fins/inch. Finned tube materials must be traceable for ASME purposes. Lengths range from 48" to 138". Typically, we need about 6" bare pipe at each end. Can you make something like this? If so, we can send drawings with an RFQ. Thanks. **** Hidden Message ***** William Horne 30269 Company: Alternate Energy Systems, Inc.
