FAQ
Q.Is ASTM A53 galvanized?
A.Covers black and hot-dipped galvanized electric-resistance welded Grade B pipe. Pipe is intended for mechanical and pressure applications and is acceptable for ordinary uses in steam, water, gas and air lines.
Q.What is the ASTM A53 type E pipe?
A.Pipe is intended for mechanical and pressure applications and is acceptable for ordinary uses in steam, water, gas and air lines. Pipe is suitable for welding and threading.
Q.What is the difference between ASTM A53 grade A and B?
A.ASTM Grade B has higher mechanical requirements, different chemical composition, and higher test pressures than Grade A. Grade B meets and exceeds all of the properties of Grade A.
