Brief Introduction of API-5L ERW Steel Pipe
This API 5L ERW steel pipe designed for oil and gas pipelines for various working environments. It generally made of carbon steel and meets API SPEC 5L specifications. It intended for petroleum and natural gas industries, oil industries requirements for transportation, and expected to work in extreme conditions, low and high temperatures, corrosion resistance in corrosion environments, and sour services in H2S environments.
Welded (ERW, LSAW, SSAW) Steel Line Pipe Grade Feature

API-5L ERW Steel Pipe Manufacturing Process
ERW process normally applied to the pipe below 24 in, 609 mm. ERW/HFW Longitudinally Welding Steel Line Pipe (Electric Resistance Welding ) Manufacturing Flow Chart.
Uncoiling – Flattening – Shearing and Butt Welding – Loop Storing – Plate UT – Trimming – Forming – High Frequency Welding – Removal of Inside and Outside Blurs – Ultrasonic Testing – Annealed by Medium Frequency – Air Cooling – Water Cooling – Sizing – Straightness – Cutting Off – Dimension and Initial Surface Inspection – Pipe Ends Beveling – Hydrostatic Test – Ultrasonic Testing of Entire Tube – Off Line Ultrasonic Testing – Ultrasonic Testing for Pipe Ends – Dimension and Final Surface Inspection – Corrosion Resistant Coating – Marking – Pipe Ends Protection – Inspection and Warehousing.
API 5L ERW Pipe produced under the American Petroleum Institute specifications. The pipes used in transporting petroleum products and other along a long line of pipes. Therefore the pipes have to be strong, corrosion resistant and wear resistant.
