• Specifica di A53:Tubo, In acciaio, Nero e caldo,Zincato, Seamless
•Materiale: ASTM A53 Grade B
• Dimensione:ASME B36.10
• Terminare la connessione: pianura / smussato / NPT threaded
•Superficie: Nude / vernice nera / Hot-dip galvanized coating
• Prova idrostatica: ASTM A53
• Test CND: ASTM E309 Esame a correnti parassite
ASTM E570 Esame delle perdite di flusso ASTM E213 Test ad ultrasuoni

ASTM A53 is Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service.
ASTM A106 is Standard Specification for Pipe, In acciaio, In bianco e caldo-tuffato, Zincato, Welded and Seamless1

A53 Pipe vs A106 Pipe – Applied Type of Pipe

A 53 can be welded seam or seamless depending on how it is specificed for purchase. It is a general steel pipe spec and covers galvanized pipe as well as black pipe.
A106 is a similar pipe in chemical composition but is intened for high temperature service (Fino a 750 Degs F). It is a seamless pipe.
