ASTM A53 Seamless Steel Pipe for Gas Service SCH40 SCH160 API Certified

ASTM A53 Seamless Steel Pipes In Gas Service SCH40 SCH160

Description

ASTM A53 seamless pipes (Type S, Grades A & B) are manufactured without any welded seam, offering superior strength and uniform structure. According to the ASTM A53/A53M standard, pipe ordered under this specification is acceptable for ordinary uses in gas lines. A53 is the most commonly installed type of steel pipe used for fuel gas service. Grade B is the most widely specified grade, with a minimum yield strength of 35,000 psi (240 MPa).

A53 Seamless Water 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.
