Where can I find the various standards for the processing and manufacturing of fillers?

Our company is going to issue a tender for the packing materials used in its methanol project; the main types include stepped rings, Pall ring, and wire mesh corrugated rings. We are urgently in need of the manufacturing standards for these various types of packing materials
HG/T 21559.3-2005 is the standard for stainless steel corrugated mesh packing; you can download it for free by visiting http://www.bzfxw.com/
Does the original poster still need these technical standards? Has the bidding process been completed?
You can find it by doing a standard online search; it’s available everywhere. The key is to choose the appropriate filler based on one’s own process requirements
