Comparison of tensile properties for seamless and welded API 5L PSL1 steel pipe

The API SPEC 5L includes seamless and welded steel line pipe. And their main usage is on the fluid transportation, gas and oil. And here is the question: which kind of steel pipe line should customers choose from? Is it the seamless steel pipe or welded one?

Here we can make a list for comparison of the difference on tensile properties and we hope this would give you guide when you are in trouble for choosing.

From the list, we can tell the exact difference on tensile properties. And thus customers can choose according to the engineering project’s required tensile properties.
