What Are API 5L X46 Pipes?
API 5L X46 pipes are part of the API 5L specification established by the American Petroleum Institute for line pipes used in the oil, gas, and water industries. The “X46” grade signifies a minimum yield strength of 46,000 psi, making these pipes suitable for moderate to high-pressure applications. These pipes are available in both PSL1 and PSL2 (Product Specification Levels), with PSL2 offering stricter quality controls.
