Why use API 5L X60 steel coil to make welded pipes

API 5L X60 steel coil is one of the most widely used pipeline steel. The API 5L specification provides standards for pipes suitable for use in conveying gas, water, and oil in the natural gas and oil industries. The API 5L covers seamless pipe and welded steel line pipe.

With the developed market needs for oil and gas energy, the heavy and large diameters line pipes are increasingly required in the pipeline transmission systems. But seamless pipe is not easy to be manufactured more than 40 inch diameters (generally OD is below 20”). Under such situation, pipeline steel plate / coil is coming up and has been taken as the raw material for making API 5L line pipes. For example, API 5L X60 steel coil is used to make to make API 5L X60 welded pipes. API 5L X60 steel coil has two levels: API 5L X60 PSL1 and API 5L X60 PSL2.

API 5L X60 steel coil is a medium high grade in API 5L specification. It is corresponding to ISO 3183 L415. API 5L X60 steel is applied in the oil and gas transportation systems and petroleum industries.
