Differences In The Production, Manufacturing And Use Of Stainless Steel Elbows And Stainless Steel Elbows
Stainless Steel Weld Elbow is distinguished by specifications:
Small and medium-sized are seamless elbows. At present, the maximum diameter of domestic seamless elbows is 40", that is, Φ1020, which is within the range of DN15-DN1000. Large specifications are generally steel plate butt welding elbows. This process can also be divided into long radius elbows and short radius elbows. The specifications involved are: around DN500-DN2500.
The use of steel elbows is more special than elbows, but these two types of pipes generally do not conflict.
Differentiation of steel elbows:
Differentiation based on R: r is the radius, usually starting with 3D, until the size required by the working conditions, that is, R is unlimited, as long as it exceeds 3D. According to the distinction of angles, the angle is also unlimited, and there is also a distinction between seamless and seamed. Generally, it is a small seamless specification, using a seam Large specifications, such as spiral welding, etc.
According to the production process: medium frequency hot bending process, seamless push process, CNC machining process.
1. First of all, let's talk about the process:
The process of seamless elbow is hot push, cold press and hot press, and the process of pipe bending is medium frequency bending, hot press and CNC bending. Among them, carbon steel is the most commonly used elbow in pressure pipes, alloy steel is hot push, stainless steel is cold push, and the most commonly used process for pipe bending is medium frequency bending.
2. The difference in scouring strength:
The R of the elbow and the elbow itself is different. R is a position that controls the length of the elbow and the elbow. The scouring strength of the small R through the medium is definitely much greater than that of the large R. That is to say, the scouring strength of the 1D elbow is not as good as that of the 1.5D elbow. The scouring strength of the 1.5D elbow is lower than that of the elbow, and the elbow is more resistant to scouring and wear than the elbow.
