公告内容：All Bidders,
The requirements of the 24 inch Ball Valves Package have been revised as below,
1. 4 Nos valve steam need to be extended within 800mm due to the layout & accessibility. Bidder to consider and include this requirement in the quotation.
2. Revise the LTCS valve body material / construction requirement for NPS 2' and larger ball valves from ASTM A350 Gr. LF2 forged body to ASTM A352 Gr. LCB cast body, subject to compliance with ASME B16.34, the applicable valve product standard such as API 6D or API 608 as applicable, Project design pressure, design temperature, impact testing, nondestructive examination, hydrostatic test, seat test, material certification and traceability requirements.
3. Revise the ball and stem material for the relevant ball valves from ASTM A182 Gr. F316 to ASTM A182 Gr. F51, subject to compliance with the applicable valve datasheet, service compatibility, material certification, hardness / sour service requirements where specified by the Project, inspection and testing requirements, and vendor design qualification.
4. Revise the pup piece material / wall thickness requirement for CS piggable ball valves from API 5L PSL2 Gr. X65, 19.05 mm wall thickness and 200 mm length at each end, to ASTM A694 Gr. F65 forged material. The valve-end wall thickness shall match the valve body wall thickness, the pipe-end wall thickness shall remain 19.05 mm, and the minimum piggable through bore / ID shall remain 571.5 mm.
5. Accept ASTM A105N for the relevant CS valve bonnet material as normalized ASTM A105 material, subject to compliance with ASTM A105 / A105M, applicable heat treatment, material certification, pressure-temperature rating, inspection and testing requirements.
All other requirements of the Piping Material Specification, valve datasheets, applicable valve standards, Project specifications, inspection and testing requirements, certification requirements and Project service requirements shall remain unchanged.
Bidder to consider and include above requirement in the quotation.
