As we know, ASTM A53 steel pipe is always required with large quantities from different industries, so what is A53 pipe ?
ASTM A53 steel pipe is the most commonly used grade in the ASTM A53 standard. And it includes three types in pipeline systems:
a. Seamless pipe type
b. Welded pipe type (ERW, EFW, HFW, SAW)
c. Hot Dipped Galvanized pipe type
ASTM A53 is the standard specification for the carbon steel pipe in seamless, welded, and zinc-coated galvanized pipes. Covers the dimensions ranges from OD 10.3 mm (1/8 inch) to 660 mm (26 inch).
Find here Differences between ASTM A53 and ASTM A106.
a. Seamless Type S, has grade A and B.
b. Welded Type E (ERW), Grade A and B.
c. Furnace Welded Type F, Grade A only.
ASTM A53 standard specification including hot dipped galvanized (zinc coated) requirements for ASTM A53 Grade B steel pipe.
Moreover, there are pipe internal and external galvanization. By the hot dip procedures, zinc thickness of any grade shall be complied to specification B 6.
Seamless steel pipe manufacturing process is divided into hot-rolled and cold seamless pipe.
1. Production process of hot-rolled seamless steel pipe:
tube billet → heating → perforation → three-roller/cross-rolling & continuous rolling → de-pipe → sizing → cooling → straightening → hydraulic test → marking → seamless steel pipe with leverage effect detected.
2. Production process of cold drawn seamless steel tubes:
tube blank → heating → perforation → heading → annealing → pickling → oiling → multiple cold drawing → blank tube → heat treatment → straightening → hydraulic test → marking → storage.
| Seamless and ERW | Grade A | Grade B |
|---|---|---|
| Tensile Strength, min, psi | 48,000 | 60,000 |
| Yield Strength | 30,000 | 35,000 |
| Seamless and ERW | C max % | Mn max % | P max % | S max % |
|---|---|---|---|---|
| Grade A | 0.25 | 0.95 | 0.05 | 0.045 |
| Grade B | 0.30 | 1.20 | 0.05 | 0.045 |
