ASTM A53 Type E, Grade A Pipe

1 astm A53 Type E, Grade A pipe SUBMITTAL DATA SCOPE Covers black and hot-dipped galvanized Electric Resistance Welded Grade A pipe . 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, threading, grooving and bending. pipe is not intended for flanging. Produced to latest revisions of astm A53/A 53M, and ASME pipe is also UL, ULC listed, sizes 1/2 to 6 S40, and FM approved 1 to 6 S40 (not included 3 , 5), for use in Fire Sprinkler pipe applications. HOT-DIPPED GALVANIZED The average weight of zinc coating shall be not less than oz. per sq. ft. of surface (inside and outside) When galvanized pipe is bent or otherwise fabricated to a degree which causes zinc coating to stretch or compress beyond the limit of elasticity, some flaking of the coating may occur. Produced to the latest revisions of astm 123/A. HYDROSTATIC TESTING and NONDESTRUCTIVE ELECTRIC TESTING Hydrostatic test pressures for plain-end pipe are indicated below.

2 (PSI). Test pressures shall be maintained for a minimum of 5 seconds.
