What is the fixed length of SSAW welded pipe?
The standard fixed lengths of SSAW (Spiral Submerged Arc Welded) pipes are generally 6 meters, 12 meters, and 18 meters. These lengths are determined based on production needs. Typically, shorter fixed lengths are chosen for smaller diameter pipes, while longer fixed lengths are selected for larger diameter pipes.

API 5L welded steel pipe
The American Petroleum Institute (API) released the API 5L standard in early 1926, initially covering three steel grades: A25, A, and B. Over time, additional grades were introduced. By the year 2000, the global use of steel grades for pipelines was distributed as follows: X70 accounted for approximately 40%, X65 and X60 for about 30% each, and a significant number of small-diameter product pipelines used X52 steel grade, primarily for resistance-welded straight pipes (ERW steel pipes).
