Material of construction

Meaning in chemical engineering, with examples

nounCommon term

In chemical engineering, material of construction means: The material that a piece of equipment, pipe or part is made from, chosen for strength, temperature, corrosion resistance and cost.

In Turkish: imalat malzemesi, ekipman malzemesi, yapım malzemesi

How it is used

Abbreviated MOC and listed on every datasheet and P&ID line list. Engineers select, specify and upgrade the material of construction, and check compatibility with the process fluid. Typical options include carbon steel, stainless steels, nickel alloys, glass-lined steel and plastics.

Example sentences

  1. What's the material of construction for the new scrubber? The gas contains wet HCl.

  2. The datasheet lists Hastelloy C-276 as the material of construction for wetted parts.

Common collocations

  • MOC selection
  • upgrade the material of construction
  • materials of construction
  • wetted parts
  • stainless steelA family of steels containing at least about 10.5% chromium, which forms a thin protective oxide layer and gives much better corrosion resistance than carbon steel.
  • corrosionThe slow damage of a metal by chemical or electrochemical reaction with its surroundings, such as rust on carbon steel or attack by acids and chlorides.
  • corrosion allowanceExtra wall thickness added to a vessel or pipe on top of what strength calculations require, so that it can lose metal to corrosion over its life and still be safe.
  • pressure vesselA closed container designed to hold gases or liquids at a pressure well above or below atmospheric, such as a reactor, separator, drum or column.
