Abstract
It would be difficult for domestic enterprices to carry out the design,procurement and construction part of overseas EPC project on the basis of different regions'codes & standards.How to set a rational pressure difference across the evacuation-door for stairwell pressurization system,acts as a significant step of design.Key points of executing design and procurement part of the overseas project,as far as smokeproof system be concerned,has been dug by means of contrasting the items,perspectives and calculation methods between Chinese(GB,XF)and American(NFPA,ANSI)standards.Suggestions for standards' revision has been proposed as well.关键词
