Tubes that can withstand extreme structural stress are referred to as high yield steels. In demanding applications, High Yield Carbon Steel Pipe are exposed to stresses of varying types. Hence, these pipes are required to be conditioned to withstand the occurrence of stress in the form of abrasion, compression, tension, impacts and vibration.
Any of these stressors would be enough to damage a regular carbon steel pipe, but not the HY ones, which is why they are recommended by high yield pipe distributors. Damage like structural displacement, deformation, or mechanical failure are common during the occurrence of stress. The use of a High Yield API 5L Line Pipe, ensures high integrity and service life longevity on the event of outstanding pressure or stresses. It is common for steel alloys to witness a decrease in mechanical properties after processes such as quenching and tempering. However, in the case of a High Yield Strength Pipe, there is no tangible decline in the performance of the material. The significant additions of titanium & molybdenum in the high yield strength steel pipe imparts it with an exponential increase in its strength. Generally, the High Yield API 5L Line Pipe is used in the oil and gas & water industries for the transportation of fluids, steam, gas etc. Grades A, B & X belonging to the API 5L specification High Yield Seamless Tubes tend to be well suited for applications like production, drilling, and transport requirements. These requirements are a part of industries such as arctic, offshore, deep well, or any harsh environments.
