Stainless Steel Pipe Fittings 45 Elbow A403 Grade WP 316 DN150 SCH10S Seamless Elbow

Introduction to Elbows

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%)

316 stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial transportation pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, machinery and instruments. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used to manufacture mechanical parts and engineering structures. It is also used to produce various conventional weapons, gun barrels, shells, etc.
