What are ASTM a672 b70 pipe classes?
ASTM a672 b70 pipe classes are standard pipe classes used for manufacturing electric fusion welded steel pipes for high-pressure service at moderate temperatures. The classes consist of three groups based on the nominal wall thicknesses, designated as Class A (thinnest), Class B (intermediate) and Class C (thickest). Each class is further divided into four levels based on minimum yield strength, with each level representing an increase of 20 MPa over the preceding one. This standard also covers technical requirements for the selection, qualification and preparation of components used in the manufacture of electric fusion welded steel pipes.

Are ASTM a672 b70 EFW pipes suitable for high-pressure applications?
Low carbon steel ASTM A672 Grade B70 pipe is designed for high-pressure applications at mild temperatures. Pipes that have been electric fusion welded are specified. The pipes are created by joining filler materials to pressure vessel-grade plates using electric fusion welding. The A672 B70 Carbon Steel EFW Pipes have greater diameters as a result of this process. The majority of traditional techniques work well to weld them. The pipes don’t need to be high-temperature tolerant since these are for low to moderate-temperature operations. The pipes must also undergo post-weld heat treatment to prevent welding fractures.

Which method is used for welding ASTM a672 b70 pipe?
Shielded Metal Arc Welding (SMAW), sometimes referred to as Stick welding, is the suggested welding technique for ASTM A672 B70 pipe. This technique offers a low-cost, high-quality weld that is simple to conduct in the field, making it appropriate for worksite jobs. The filler metals’ chemical makeup, preheat requirements, and appropriate post-weld heat treatment must all be met by the welding process. Shielded Metal Arc Welding (SMAW) with a low hydrogen electrode is the suggested technique for welding ASTM a672 b70 pipe because it will give a sufficient and consistent level of weld joint strength while also satisfying ASTM A672 specifications.

Why is ASTM a672 gr b70 pipe post-weld heat treated?
Due to this equipment being utilized in situations that only reach mild to moderate temperatures, the pipes do not need to be able to endure extremely high temperatures. Nevertheless, the A672 Grade B70 LSAW Pipes need to be preheated to be welded using high-temperature procedures. To prevent fractures caused by the welding process, the pipes need to be heat treated after they have been welded.

How to thread ASTM a672 b70 carbon steel EFW pipe?
Choose a threading tool appropriate for the material and size of the pipe you are working with, such as an NPT pipe tap for standard sizes.
Place the tool on one end of the pipe and start turning it clockwise until you reach the desired depth of thread.
Slowly and carefully adjust the speed of rotation and pressure as needed to ensure that all threads are cut evenly and cleanly.
Measure out every tenth thread using a pitch gauge or calipers.
Once you have achieved the desired thread depth, remove the tool from the pipe and inspect the newly formed threads to ensure that they meet pipe standards.
Clean with a cleaning brush or cloth.
