ASTM A179/ASME SA179 Standaard bedekt minimale muurdikte, naadloze koolstofarme koude stalen buis voor buisvormige warmtewisselaars, condensers en soortgelijk warmteoverdrachtsapparaat.
ASTM A179/ASME SA179 buizen moeten worden gemaakt door het naadloze proces en moeten koud worden getrokken. ASTM A179/ASME SA179 buizen moeten worden verwarmd behandeld na de uiteindelijke koude getrokken doorgang bij een temperatuur van 1200 ° F [650 ° C] of hoger.
ASTM A179/ASME SA179 -buizen moeten productanalysetest, hardheidstest, mechanische test, afvlakke test, afvlakke test, hydrostatische test of NDT -test doen indien overeengekomen door de client.

These permissible variations in length apply to tubes before bending. They apply to cut lengths up to and including 24 ft [7.3 m]. For lengths greater than 24 ft [7.3 m], the above over-tolerances shall be increased by 1⁄8 in. [3 mm] for each 10 ft [3 m] or fraction thereof over 24 ft or 1⁄2 in. [13 mm], whichever is the lesser. |
