ASTM A53 Gr.B Seamless Tube Sch40 Bare Pipe For Mechanical API Certified

Product Specification

ASTM A53 Gr.B Seamless Steel Pipe Sch40 Bare Pipe API Certified

ASTM A53 Steel Pipe Description

ASTM A53 is a standard specification from ASTM International that covers seamless and welded black and hot-dipped galvanized steel pipe for mechanical and pressure applications, as well as for ordinary uses in steam, water, gas, and air lines. Though it’s not specifically designed as casing pipe (which is typically covered under API 5CT), A53 pipe is sometimes used as a casing alternative in structural or shallow well applications.

ASTM A53 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.
