High-Pressure Seamless Pipe ASTM A106 API 5L

High-Pressure Seamless Pipe ASTM A106 API 5L

Description

High-Pressure Seamless Pipe is manufactured without a welded seam, providing superior strength, uniform wall thickness, and exceptional reliability for demanding high-pressure applications. Produced by hot finishing or cold drawing solid steel billets, seamless pipe eliminates the weak points associated with longitudinal welds, making it the preferred choice for critical service where safety and integrity are paramount.

High-Pressure Seamless Pipe Application

• Oil and gas transmission pipelines (high-pressure)
• Refinery process piping (high-temperature, high-pressure)
• Power generation (boiler tubes, superheaters, steam lines)
• Chemical and petrochemical plants
• High-pressure hydraulic systems
• Compressor and pump station piping

High-Pressure Seamless 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.
