Alloy elbows are mainly used to connect pipe fittings in pipe installation and to connect elbows. Connect two pipes of the same nominal diameter so that the pipe bends 90 ° or other angles. Alloy elbow is the general name of all kinds of elbows, with a variety of materials, such as carbon steel, manganese steel, nickel steel, etc. Alloy elbow is widely used. Ordinary bronze alloy elbows are more common in ordinary water pipes, but with the improvement of living standards, many water pipes use stainless steel elbows. Alloy elbows made of manganese steel are usually used for concrete pipes, mud pipes and other pipes with serious wear and consumption. This is because manganese steel has good resistance to impact, extrusion and material wear. Nickel steel alloy elbows are usually used in pipelines with high concentration of oxidizing acids (nitric acid, sulfuric acid) and other normal temperature pipelines. High manganese steel alloy elbows are used in pipelines with severe fluid flow and high impact force. However, unless the concentration of hydrochloric acid is very low, the pipeline of reducing acid (hydrochloric acid, dilute sulfuric acid, etc.) will be seriously corroded. Martensitic alloy elbow has high high temperature strength, oxidation resistance and water resistance below 650 ℃, and has vapor corrosion ability, but poor weldability. Therefore, it is commonly used in high-temperature steam transmission pipeline and water gas pipeline.

Mechanical properties for ASTM A335 P91

Material & Manufacture

Pipe may be either hot finished or cold drawn with the finishing heat treatment noted below.

Heat Treatment

• A / N+T

• N+T / Q+T

• N+T

Mechanical Tests Specified

• Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test

• For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. For small lots, at least one pipe shall be tested.

• For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.

Notes for Bend Test:

• For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test.

• Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser.

• The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion.
