Introduction to 90 degree elbow

In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45 ° and 90 ° 180 °, and other abnormal angle elbows such as 60 ° are also included according to the needs of the project. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The connection methods with pipes include: direct welding (the most commonly used method) flange connection, hot-melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

Main representative grades of duplex stainless steel

DSS can be generally divided into four categories:

Low alloy type -- the representative brand is UNS s32304 (23cr-4ni-0.1n)

PrEN value 24 ~ 25

Medium alloy type -- the representative brand is UNS S31803 (22cr-5ni-3mo-0.15n),

PrEN value 32 ~ 33

High alloy type -- the standard brand is UNS s32550 (25cr-6ni-3mo-2cu-0.2n),

PrEN value 38 ~ 39

Super duplex stainless steel type -- standard grades include UNS S32750 (25cr-7ni-3.7mo-0.3n),

PrEN value ＞ 40

(※ prEN pitting resistance index pren=cr%+3.3 × Mo%+16 × N%)
