ASTM A106-Gr B
- The common pipe material for steam piping networks is ASTM A106-Gr B. This material is used for steam piping when the pipe design temperature is up to 426 degrees C. When the design temperature exceeds 426 degrees (high-temperature superheated steam piping), allow steel materials to be used.

As pipes and pipelines carry various liquids and gases having different process conditions, the proper selection of pipe material is very important. The main process parameters that govern the piping material selection process are: 1. Types of Fluid to be handled (Flammable, Explosive, Corrosive, Reactive, Volatile, or Hazardous to human skin). 2. ...
Selection of basic Piping Metallurgy and Material (viz. CS, LTCS, AS, SS, etc.) for piping specification lies with the Process/Metallurgy Engineer. The main selection is based on process, licensor, and/or intrinsic metallurgy requirements to suit process medium, like corrosion, high temperature, pressure, etc. This basic selection shall also addres...
Metals are rarely used in their purest form as they have low mechanical strength. Alloying helps increase its properties like strength and ductility. (Easiest eg. is adding Carbon to Iron to produce ferritic Carbon Steel). Addition of alloying elements in proper proportions along with appropriate metal processing and heat treatment results in the o...
Certain mechanical properties are also considered while selecting pipe material for a specific service. They are 1. Modulus of Elasticity (Young’s Modulus)– the ratio of stress to strain and measured using tension tests 2. Elastic range:Material returns to its original shape after the load is released 3. Plastic range:Material is permanently deform...
Before diving into the actual piping material selection process, let’s learn some of the important terms relevant to pipe materials. 1. Creep Strength– Ability of a metal to withstand constant weight or force at elevated temperatures without yielding 2. Brittle fracture– Sudden & rapid failure of a metal due to the application of energy with hardly...
The main alloying elements that influence the properties of pipe materials and hence their selection are 1. Carbon (C)– More carbon means more strength and hardness but less ductility and toughness. 2. Phosphorus (P)– High content decreases shock resistance & ductility, making the material brittle. 3. Silicon (Si)– Increases high-temperature proper...
Now selecting a proper pipe material is a difficult task as there is a wide variety of pipe materials available in the market. Piping materials can broadly be of three types 1. Metallic Piping Materials 2. Non-metallic Piping Materials, and 3. Composite Piping Materials Metallic pipe materials can again be subdivided into two groups; Ferrous piping...
The usual features of Metallic Cast Iron pipe materials are given below: 1. Metallic Cast Iron/Ductile Iron/Malleable Iron Pipes are brittle, low-strength materials used for low-temperature applications and basic utilities like air, water, drains, etc. Low-cost material. 2. CI shall not be used on severe cyclic condition services, excessive heat, t...
The usual features of Carbon Steel Metallic Piping materials are 1. Better than CI and has higher strength. 2. Used for higher temperatures (up to 800° F or 427° C). 3. Most process services include steam piping.
Used for low-temperature services like chilled brine, chlorine liquid/gas, propylene, etc. (Bet -45°C to 485°C)Has more Carbon and no alloying elements like Cr and Mo and contains Nickel which improves low-temperature propertiesImpact properties/values at low temp are better than in CS (Charpy N Notch test)Refer to ASTM 01.01 for impact test requirements for low-temperature/cryogenic servicesChoosing the appropriate materials for steam piping is crucial due to the extreme conditions that steam systems operate under. The most common materials used are carbon steel, stainless steel, and alloy steel.
Choosing the right material of construction for steam piping is crucial for the safe and efficient operation of steam systems. This article explores the different materials available for steam piping and their suitability for different applications and conditions.
Jan 16, 2003 · Of all the materials used for high-temperature steam piping, X20 (12 percent chromium, 1 percent molybdenum, 1/4 percent vanadium) and P91 (9 percent chromium, 1 percent molybdenum, 1/4 percent vanadium) stand out because of their very high creep rupture properties, even at elevated temperatures.
