The American Petroleum Institute specification API 5L is designed for transportation systems in the petroleum and natural gas industries for conveying gas, water, and oil. API 5L X60 is a steel grade of API 5L which specifies the manufacture of two product levels (PSL1 and PSL2) line pipe. WLD Steel is one of the large manufacturers, suppliers of  API 5L steel pipe, we also provide internal & external coating like Black paint, varnished, FBE coating, 3LPE coating and all lined pipe on steel pipes as per the customers’ requirement. WLD steel supply and manufactured a large inventory of  API 5L X60 steel pipe in PSL1 and PSL2.
