What is the material composition of the high-alloy used to transport hot sulfuric acid?
Thread Content
I heard that some sulfuric acid plants these days use high-alloy pipes to transport hot acid. I wonder what material and components make up this so-called HGO
This involves technical confidentiality issues; generally, manufacturers will not tell you the specific components
Use duplex stainless steel 904. Just search for 904 on Baidu
Reply to 3# pangrujian30: It’s not just the 904 material; there are also some other alloys.
Of course, it’s not just the components of material 904.
Generally, specialized high-silicon stainless steels are used, such as Zecor, Sandvik SX, Saramet 35, as well as XDB series from Xuanda mentioned above; these materials are employed for high-temperature concentrated sulfuric acid at temperatures below 200 degrees and with concentrations of 93%–98%
High-silicon stainless steel, containing 15-16% Ni and 5.5-6.5% Si
An entity that manufactures high-alloy pipes used for transporting hot sulfuric acid is introduced. http://www.susepipe.com/product/showproduct.php?lang=cn&id=22 is a composite pipe that is highly resistant to corrosion. You can get in touch and communicate with them!
