Abstract:
TxDOT plans and specifications currently do not allow use of furnace butt welded pipe for sign supports. Use of this type pipe, if it is suitable and demonstrates acceptable performance for small sign supports would result in significant cost savings.Samples of furnace butt welded and electrical resistance welded, 51 mm I.D. schedule 40 pipe were subjected to static bending tests. Selected samples of furnace butt welded pipe were also used in pendulum and full-scale vehicle crash tests.Researchers found that furnace butt welded pipe meeting ASTM A53 and having a yield strength of at least 240 Mpa demonstrates acceptable performance for small sign supports.
