Oil And Gas Line Pipe ASTM A106 API 5L GR.B

Description

API 5L Line Pipe is the global benchmark for steel pipe used in pipeline transportation systems within the petroleum and natural gas industries. Manufactured to the American Petroleum Institute's Specification 5L, this pipe is essential for the safe and efficient transmission of oil, gas, and high-pressure fluids over long distances.

Oil And Gas Line Pipe Application

• Cross-country oil and gas transmission pipelines.
• Offshore and subsea pipelines.
• Sour service pipelines.
• High-pressure gas transmission systems per ASME B31.8.
• Gathering and flow lines in upstream operations.
• Water transmission mains.

Oil And Gas Line Pipe Manufacturing Process

The process begins with solid steel rounds, or billets, being cut to a specified length and sent through a walking-beam reheat furnace, where temperatures reach nearly 2,300°F. After exiting the reheat furnace, the preheated rounds are turned into a tube shell in the rotary piercing mill as the billets are cross-rolled between two barrel-shaped rolls at a high speed.

The seamless shells enter mandrel mill, where they are rolled over a retained mandrel to provide the needed OD size and wall thickness for the next process. The process is carefully monitored using a state-of-the-art hot-wall measuring system. The shells are then reheated for final forming in a 24-stand stretch-reducing mill, where outside diameters are formed to customers’ exacting specifications. Wall thickness is again verified using a hot-wall measuring system. After being rotated and advanced on the walking-beam cooling bed, the pipes are batch cut and transferred to an in-process storage area, where they are handled by computer-controlled gantry cranes.
