strange requirement of small diameter pipe steels
What is Nominal Pipe Size? Nominal pipe size (NPS) is the number that defines the size of the pipe. For example, when you say 6 pipe, the 6 is the nominal size of that pipe. However, for the pipe sizes, NPS 14 and above Outside Diameter is the same as NPS. To understand this concept, you have to learn the way pipes are manufactured.

Intermediate sizes and the sizes NPS 1/8, 1/4, 3/8, 1-1/4, 2-1/2, 3-1/2, and 5 shall not be used except when necessary to match equipment connections. In this case, a suitable transition shall be made as close as practical to the equipment.

Flexible pipe is designed to transmit the load on the pipe to the soil at the sides of the pipe. As the load on the pipe increases, the vertical diameter of the pipe decreases and the horizontal diameter increases. The increase in horizontal diameter is resisted by the soil at the sides of the pipe. The soil must be strong enough so Steel Standards - ASTMASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.

for small diameter welds. The scanner itself can be adapted to a range of sizes, which can be matched to the pipe diameter. As it is spring-loaded, the scanner can inspect both carbon steel and non-magnetic materials (e.g. stainless steels) with no changes. Experience has shown that the scanner provides good coupling for 360o round the pipe,
