Black mild steel blind casing as per API 5L/ASTM A53 NPT Thread

Black mild steel blind casing is mostly done as per API 5L /ASTM A53 standards with NPT thread.

This kind of casings, very different from API 5CT casings in threading, are often used in water well drilling projects.

The pipe body can be ERW or Seamless .

Here, we mainly talk about ERW type:
