Material of pipes used in coal water slurry gasification equipment
Thread Content
Which stainless steel pipes are used in the coal-water slurry gasification device? What I know is the oxygen pipe. Are the water gas pipes and the black water pipe at the quench outlet of the gasifier also made of stainless steel? Are the coal-water slurry pipes and other black water and gray water pipes made of thickened carbon steel? What is the wall thickness?
Including the black water pipe at the gasifier outlet, the black water system uses carbon steel pipes, and the wall thickness is related to the pressure the pipe withstands.
A corrosion allowance of 2~3mm should be added to black water pipelines
The downcomer is made of stainless steel! The oxygen pipe is also made of stainless steel, and the others are generally made of carbon steel!
There are many stainless steel pipes used in coal water slurry gasification equipment, but some pipes are related to the style of the design institute and do not necessarily have to be made of stainless steel. For example, for black water pipelines, some factories use carbon steel and some use stainless steel. However, the specification and grade of the pipeline must be determined based on pressure level, temperature, medium, etc.
