API 5L General Information
The API SPEC 5L specification provides standards for pipe suitable for use in conveying gas, water, and oil in the natural gas and oil industries. The API SPEC 5L covers seamless and welded steel line pipe. It includes plain-end, threaded-end, and belled-end pipe, as well as through-the-flowline (TFL) pipe, and pipe with ends prepared for use with special couplings.
Pipe manufactured to ASTM106 Grade A or B are not interchangable with API 5L . Requirements to API 5L X grades are more stringent; rolled grades are not acceptable and rework is not allowed. Moreover, particular attention is given to toughness and toughness tests for sour services and higher pressure & temperature classes.
API 5L carbon steel pipes are widely available and relatively affordable, making them a popular choice for very large projects such as pipelines. Canada Steel and Casing Imports have a Surplus stock of API 5L Grade B Seamless Pipes and Welded Pipes. API 5L Grade B seamless pipes are one of our most widely used grades of carbon steel and are readily available ex-stock for all standard thicknesses up to SCH160. Canada Steel and Casing Imports is a trusted distributor & exporter of API 5L line pipes produced by certified international mills.

API Standard Specification for Line Pipe
The American Petroleum Institute specification API 5L addresses seamless and welded steel line pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil.
Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, standardizing pipeline transportation systems within the materials, equipment, and offshore structures for natural gas, petroleum, and petrochemical industries. When authoring the standards, the technical committee recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2. PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.
Grades covered by this specification are A25, A, B and “X” Grades X42, X46, X52, X56, X60, X65, X70, and X80. The two-digit number following the “X” indicates the Minimum Yield Strength (in 000’s psi) of pipe produced to this grade.
