What’s the difference between API X42 and X52 pipe? Grades covered by API 5L standards are A25 ,A ,B and "X" Grades such as X42, X46, X52, X56, X60, X65, X70, X80 ans so on). The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade. Here I will show you the comparison between X42 and X52.

ASTM standards fall into the following six categories Standard Specification that defines the requirements to be satisfied by subject of the standard. Standard Test Method that defines the way a test is performed. The result of the test may be used to assess compliance with a Specification. Standard Practice that defines a sequence of operations that, unlike a test, does

ASTM A53 Standard 1. Scope of ASTM A53 Standard ASTM A53 is standard specification for pipe, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in
