Seamless Tube ASTM A106 Pipe For High-Temperature Service

Description

A seamless carbon steel pipe is a heavy-duty tube manufactured from a solid steel billet without any longitudinal weld seams. This unique structure provides uniform strength and superior ability to withstand high pressure and temperature compared to welded pipes.

Manufactured to ASTM A106 (high‑temperature service), ASTM A53 (general service), and API 5L (line pipe) standards, beveled end seamless pipe is available in Grades A, B, C, and API 5L X42–X80, with a full range of sizes and schedules.

Seamless Steel 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.
