Questions buyers ask about A179
Is ASTM A179 the same as ASME SA179?
Effectively yes. SA179 is the ASME Boiler and Pressure Vessel Code adoption of ASTM A179 and carries the same requirements. Tell us which designation your design code calls for and the tube is certified to it.
Can A179 be used for boiler tubes?
A179 is written for heat exchangers, condensers and similar heat transfer equipment. High-pressure boiler tubes are normally specified to ASTM A192. See our A179 vs A192 vs A214 comparison.
Is there a minimum order?
No. We quote from a small retube to a full new exchanger bundle.
How long does A179 tube take to arrive?
Every quote states a lead time for each line. Sea freight suits planned work; air freight is available when a shutdown or tender deadline needs the tube sooner.
