On the surface, there is only one word difference between seamless elbow and seamless elbow pipe. In fact, they are very different. One is an elbow, and the other is a bent pipe. The following is an analysis of the differences between the two. 1. Technology The processes of seamless elbows include hot pressing, hot pressing and cold pressing; the [...]

Stainless steel seamless elbows are mainly used in the turns of pipes. They have good thermal insulation and high temperature resistance. In addition, they have the following advantages: 1. Heat resistance: Stainless steel seamless elbow has good heat resistance. When the working water temperature is 70°C, the softening temperature is 140°C. 2. Corrosion resistance: Except for a few hydrogenating agents, [...]

There are many standards for stainless steel seamless elbows. In this article, what are the common standards we mainly understand? Japanese standard Standard No. Description JIS B2311 General purpose steel butt welding pipe fittings JIS B2312 Steel butt welding pipe fittings JIS B2313 steel plate butt welding pipe fittings JIS B2316 Steel socket welded pipe fittings American standards for pipe [...]

Stainless steel seamless elbows are used at pipeline turns. They have good corrosion resistance, heat preservation and impact resistance, are hygienic and non-toxic, and have a long service life. Next, we will share with you the manufacturing standards and manufacturing methods of stainless steel seamless elbows. Manufacturing standards for stainless steel seamless elbows: national standard, American standard, German standard, Russian [...]

Cracks on the surface of stainless steel seamless elbows are caused by many factors, including raw materials, temperature, equipment and process issues. Let’s talk about the problem of raw materials first. If the raw materials selected for stainless steel seamless elbow are of poor quality, there will be internal and external warping, cracks, scarring and other phenomena. In terms of [...]

There are mainly five common forming processes for stainless steel seamless elbows: 1. Forging process: Use a forging machine to punch the pipe end or part to reduce the outer diameter. 2. Rolling process: Place a core inside the tube and push the outer circumference with rollers for round edge processing. 3. Stamping process: Use a tapered core on a [...]
