Introduction
Elbow is a commonly used connecting pipe fitting in plumbing installation. It is used for the connection at the bend of the pipeline and to change the direction of the pipeline.
Other names: 90 ° elbow, right angle bend, love bend, stamping elbow, pressing elbow, machine-made elbow, welding elbow, etc.
Purpose: connect two pipes with the same or different nominal diameter to make the pipeline turn 90 °, 45 °, 180 ° and various degrees.
Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow
Overview and features
Duplex stainless steel alloy S32205 (S31803) consists of 22% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance. The yield strength of S32205 (S31803) duplex stainless steel is more than twice that of ordinary austenitic stainless steel, so that designers can reduce the weight when designing products. In this regard, this alloy is more competitive than 316 and 317L S32205 is especially suitable for use in the temperature range of - 50 ° f / + 600 ° F. beyond this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures
Advantages of UNS S31803
1) The yield strength is more than twice that of ordinary austenitic stainless steel and has sufficient plasticity and toughness required for forming. The thickness of tank or pressure vessel made of duplex stainless steel is 30-50% lower than that of common austenite, which is conducive to reducing the cost.
2) It has excellent stress corrosion cracking resistance. Even the Duplex Alloy with the lowest alloy content has higher stress corrosion cracking resistance than austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a prominent hazard that ordinary austenitic stainless steel is difficult to solve.
