Austenitic stainless steel pipe has good corrosion resistance and high strength, widely used in petroleum, chemical, aviation, shipping and other fields. Hot bending is a commonly used pipe processing methods, can make the pipe according to the design requirements for bending. Material selection, hot bending machinery and equipment, hot bending process and application cases of austenitic stainless steel pipe hot bending technology for detailed analysis.

How to distinguish between annealed and non-annealed stainless steel welded pipes? 1. The pipe can be judged by echo. Tap each pipe and listen to the echo at the nozzle. If the echo is higher, it is sharper and has been annealed. Since the internal crystal structure of the annealed part is more uniform and dense, it can produce a higher interval echo without the need for annealing. Due to a large number of organizational defects, it can absorb some sound energy, so the tone at the nozzle is very low and dull. If conditions permit, it can be detected by ultrasound.

Here are 10 methods for soaking stainless steel welded pipes in liquids: 1. Basic Treatment: Use standard acid, followed by rinsing with clean water. 2. Advanced Treatment: Includes acid washing, alkaline washing, rinsing, polishing, and waxing.

1. Differences in Production Process Stainless steel welded pipes are formed by welding rolled steel sheets or strips and then using equipment and molds. The inner walls of these pipes typically have weld seams. In contrast, seamless pipes are made from solid round billets through hot extrusion processes such as drilling, cold rolling, and cold drawing, resulting in pipes without any weld seams.

Finego welded steel pipes are created by welding steel plates or strips and know for their simple production process, high production efficiency and cost-effectiveness. The steel pipes are classified into straight seam welded pipes (LSAW) and spiral welded pipes (SSAW), providing good durability and versatility for different application scenarios.

Finego seamless stainless steel is of high quality, renowned for its strength, durability, and versatility. Seamless stainless steel differs from the welded or jointed stainless steel in its manufacturing. It is produced from a single and continuous piece of steel, which eliminates weak points and ensures uniformity. The production process includes heating a solid billet and pushing or drawing it into a tubular shape without seams or weld lines.

Human factors are the focus of gas galvanized pipe welding control. Due to the lack of necessary post-weld control methods, it is easy to cut corners and affect the quality; at the same time, the welding particularity of galvanized pipes makes it difficult to ensure the welding quality.

In terms of appearance, the difference between seamless steel pipe and welded steel pipe is that the inner wall of welded pipe has welding ribs, while seamless pipe has no welding ribs.

Spiral steel pipes are single-sided welded and double-sided welded. Welded pipes should ensure that the water pressure test, tensile strength of the weld and cold bending performance meet the requirements.

Why does the small-diameter thick-walled seamless steel pipe have transverse cracks? During the use of the small-diameter thick-walled seamless steel pipe, the surface sometimes encounters the phenomenon of transverse cracks. There are many reasons for this. The scope of application of the small-diameter thick-walled seamless steel pipe is as follows. If the deformation of the small-diameter thick-walled seamless steel pipe is relatively small in the case of air drawing, the inner and outer surfaces of the seamless steel pipe will cause additional stress fields caused by internal pulling.

Now let us introduce the American standard seamless pipe, which is a kind of seamless steel pipe. Seamless steel pipe is another kind of steel pipe. Now let us introduce the classification of hard pipe.
