API Seamless line pipe
API 5L Seamless Line Pipe is a hollow cross section, no seams round, square, rectangular steel.
This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil. Size range is limited only by manufacturer’s capabilities.
Sizes range & standard:
· Nominal Pipe Size 2" to 24" O.D.
· Wall Thickness - Schedule 10 through 160, STD, XS, XXS.
· Standard: API 5L
· Product Specification Level: PSL-2
· Steel grade :X52

Yield strength, min /max, psi (MPa) 52,000 (300)/n/a 52,000 / 76,900
Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries. The technical committee authoring the standards 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.
API standards - a abbreviation of API American Petroleum Institute, API standards are mainly required equipment performance, sometimes including the design and process specifications.
Seamless steel ingot is made of perforated or solid tube capillary tube, and then by hot-rolled, cold-rolled or cold-call is made. Seamless hollow sections, a large number of channels for transporting fluids, steel pipe and solid steel bar, etc. compared to the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding.
API 5L Seamless Line Pipe will often be categorized based upon the way in which it was manufactured. Two manin methods of manufacturing API 5L Seamless Line Pipe exist, cold drawing and finishing, cold drawing refers to a tube-building method in which the tubing is drawn, or shaped at room temperature. this method is good for creating a bettersurface finish, closer tolerances,lighter walls or smaller diameters of tubing. hot finished API 5L Seamless Line Pipe is made without the use of any cold finishing, meaning that the seamless pipe is built while the material is extremely hot. Both of these processes are commonly used.
