Sourcing Fraud During the international sourcing, sometimes you might be a victim of fraud. What should you do to see through the fraud and guard against it? Let’s take the example of sourcing ASTM A179 (ASME SA179) seamless tubes. ASTM A179 / ASME SA179 First of all, let’s get to know about ASTM A179 seamless tubes. They are mainly used for heat exchangers and condensers. Normally they are produced by cold drawn or cold rolled process. The quality requirement for them is much strict. Common sizes are O.D. 3/4” (19.05mm) and O.D. 1” (25.4mm). Beside straight tubes, there are also U-Bent tubes and fin tubes. In fact, A179 U-Bent tubes are for heat exchangers, and A179 fin tubes are for condensers. Here are photos of the three types of ASTM A179 seamless tubes: ASTM A179 ASME SA179 Straight Tubes ASTM A179 U-Bend Tubes ASTM A179 Fin Tubes Fake ASTM A179 Tubes Some customers sourcing ASTM A179 tubes mentioned that they had been fooled with fake goo
