Elongation refers to the ability of a material to undergo plastic deformation before it breaks. The minimum elongation for API SPEC 5L L290R - PSL2 steel pipes is also specified as a function of the pipe grade and size. For example, for Grade X52 pipes with a diameter of less than 2.375 inches, the minimum elongation is 21%.

API SPEC 5L is a widely recognized standard for steel pipes used in pipeline transportation. This specification covers requirements for materials, manufacture, testing, and use of steel pipes for conveying oil, gas, water, and other liquids or gases. One of the key aspects of API SPEC 5L is its mechanical properties, which are essential to ensuring the safe and reliable operation of pipelines.

The thermal properties of steel pipes are critical to ensuring the safe and reliable operation of pipelines under various temperature conditions. API SPEC 5L L245-PSL1 specifies several thermal properties requirements, including thermal conductivity, coefficient of thermal expansion, and maximum service temperature. Compliance with these requirements is ensured through various testing methods, including thermal conductivity measurement, dilatometry, and high-temperature testing. By meeting these requirements, pipelines built with steel pipes can operate safely and effectively in a variety of high-temperature environments.

The thermal properties of steel pipes are critical to ensuring the safe and reliable operation of pipelines under various temperature conditions. API SPEC 5L L415 - PSL1 specifies several thermal properties requirements, including thermal conductivity, coefficient of thermal expansion, and maximum service temperature. Compliance with these requirements is ensured through various testing methods, including thermal conductivity measurement, dilatometry, and high-temperature testing. By meeting these requirements, pipelines built with steel pipes can operate safely and effectively in a variety of high-temperature environments.

Yield strength refers to the minimum amount of stress a material can withstand before it starts to deform plastically. For API SPEC 5L L210 - PSL1, the minimum yield strength for steel pipes is specified as a function of the pipe grade and size. For example, for Grade X52 pipes with a diameter of less than 2.375 inches, the minimum yield strength is 52,000 psi (or 360 MPa).

Maximum service temperature refers to the highest temperature at which a material can operate without experiencing significant degradation or damage. API SPEC 5L L245N - PSL2 specifies that the maximum service temperature for steel pipes depends on the pipe grade and environmental conditions. For example, for Grade X52 pipes exposed to dry H2S environments, the maximum service temperature is specified as 140°F (or 60°C).
