ASTM A53 Gr.B Seamless Steel Tube for Oil and Gas Industry with Beveled Ends

ASTM A53 Seamless Carbon Steel Tube For Oil And Gas Industry 

Description

ASTM A53 seamless pipes (Type S) are manufactured without any welded seam, offering superior strength, uniform structure, and reliable pressure resistance. They are suitable for welding, coiling, bending, and flanging operations. Grade A is suitable for low-pressure applications, while Grade B offers higher tensile strength for medium-pressure systems. Service temperature is generally up to ~343°C (650°F).

ASTM A53 Seamless Carbon Steel Tube 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.
