A53 and A589 ASTM Tested
Governed by the American Society of Testing and Materials, A53 Grade is the standard specification for black and hot-dipped galvanized pipe. This material can either be welded or seamless steel pipe. This pipe is used for mechanical and pressure applications, and is also used for steam, water, gas, and air-line purposes.
ASTM A53 can be formed and welded. This pipe is all-purpose and can be used in generator plants, refineries, compressor stations, natural gas transmission, and steam conduction. A53 pipe is subject to tension bend and flattening tests, as well as a hydrostatic test. In addition, the material must also pass a non-destructive electric test.
A53 Grade pipe undergoes the galvanization process, which means the pipes are dipped into molten zinc to coat the pipe with a protective layer that will not rust. This process helps prevent aging and rusting of the steel since zinc deteriorates much slower than steel.

A589 Grade pipe, which is also governed by the ASTM, is used for water wells. This carbon steel pipe can have either plain end or threaded and coupled ends. In order to meet the specifications of this grade, the material is subjected to tensile testing, tension testing, and hydrostatic testing.
The four main types are as follows: type one, drive pipe; type two, water well reamed and drifted pipe; type three, driven well pipe; and type four, water well casing pipe.
