Differential In the Process Design Standards of Oil Pipeline between CTΓy153-39-167-2006 and GB 50253-2006

Comparison between Kazakhstan's "CTΓy153-39-167-2006 Process Design Standard for Oil Pipeline"and China's"GB 50253-2006 Design Standard for Oil Pipeline Project" is carried out.Results display that differentia exists in transportation way, tankfarm design, pressure relieving system and contamination calculation in batch transportation.In transportation way, Kazakhstan's standard adopts the subsection individual tight line running way in oil pipeline, and the length of tight line is limited; in tankfarm design for station of oil pipeline.China selects floating roof metal tank, while Kazakhstan basically uses dome roof oil tank; volume usage factor of tank specified in Chinds standard is 0.9, which is specified in more detailed way in Kazakhstans standard; in tank capacity calculation, Kazakhstans standard gives a simple regulation, however China's standard presents different regulations in initial station/inlet station, offtake station and terminaI station as well as intermittent station(heating station). In design of pressure relieving system, there is no explicit provision in China's standard, but the detailed provision exists in installation condition, location and quantity of pressure relieving system and capacity of pressure relieving system in Kazakhstans standard.In contamination calculation in batch transportation, only the empirical equation for contamination calculation in oil products batch transportation is provided in Chinas standard, while the empirical equation for contamination calculation in crude oil batch transportation is clearly given in Kazakhstan's standard, which is worth using for reference and learning.
