China National Chemical Engineering No. 2 Construction opened negotiated procurement for 53 pneumatic valves on 2 November. Responses are due on 9 November.
The package supports the EPC scope for two 450,000-tonne-per-year phosphogypsum-to-acid units in phase one of Youshan’s integrated phosphorus-coal project in Bijie, Guizhou. Procurement TPCG26195, lot 01, explicitly lists 53 pneumatic valves.
Documents are available free from 16:00 on 2 November until 16:00 on 5 November. Questions close at 16:00 on 7 November, and online responses at 16:00 on 9 November. All times are Beijing time.
Eligible manufacturers or sellers must demonstrate relevant supply experience and production qualifications or agency authorization. Consortium participation is excluded. The public announcement does not disclose sizes, pressure classes, detailed materials or a selected supplier; this remains a procurement opportunity.
Why it matters
The defined valve quantity is directly tied to acid-plant construction, but material selection still requires verified fluid, temperature and corrosion conditions.
