of the tissue machine. Tissue sheet travels from left to
right, then is creped off of the yankee dryer and wound
into a parent roll for converting into consumer products.

in the survey. Also, some deliveries during this time period were likely
replacement dryers for operating dryers that may have been retired from
service prematurely due to incidents or shell thinning.
Total yankee dryer world deliveries since 1970 were more than 1,564
cylinders, approximately 35 deliveries per year.
Since manufacturers in China did not participate in the survey, we
believe the supply of yankee dryers to Chinese tissue companies is
under-reported. In the review of yankee dryer deliveries by region, a
discussion on China to review that specific market is included.
Manufacturer information is very reliable from all participating suppliers as far back as 1970. To look at trends and growth in capacity, the
yankee dryer delivery data was sorted into three delivery periods of 15
years each: 1971 to 1985; 1986 to 2000; and 2001 to 2015.
To look at yankee dryer delivery trends per world region, the data
was sorted using the regional descriptions below:
(1) Africa & Mid-East-Algeria, Bahrain, Egypt, Iran, Iraq, Israel,
Jordan, Kenya, Lebanon, Libya, Morocco, Nigeria, Saudi Arabia, South
Africa, Syria, Tunisia, Turkey, United Arab Emirates, Zimbabwe.
(2) Asia-Australia, Bangladesh, China, India, Indonesia, Japan,
Malaysia, New Zealand, North Korea, Pakistan, Philippines, South Korea,
Sri Lanka, Taiwan, Thailand, Vietnam.
(3) Europe-Austria, Belgium, Bosnia & Herzegovina, Bulgaria, Czech
Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland,
Italy, Lithuania, Netherlands, Norway, Poland, Portugal, Romania,
Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Ukraine,
United Kingdom.
(4) Latin America-Argentina, Bolivia, Brazil, Chile, Colombia,
Ecuador, El Salvador, Jamaica, Mexico, Panama, Peru, Uruguay, Venezuela.
(5) North America-Canada, United States.

GLOBAL AND REGIONAL ANALYSIS OF
YANKEE DRYER DELIVERIES
Global Yankee Deliveries: Data from several yankee dryer manufacturers were sorted by year. The delivery of yankee dryer cylinders
has been relatively constant globally, but has varied by region. The
accompanying graphs describe this situation. Figure 5 shows global
deliveries by 15-year periods. Each time period shows deliveries of at
least 500 yankee dryers for a total global supply of 1,564 during the
45-year period.
There has been a steady supply (an increase in tissue manufacturing
capacity) of yankee dryers delivered and installed globally when analyzed
over the three 15-year periods, from 1971 through 2015.
Regional Yankee Deliveries: By analyzing yankee dryer deliveries by
region and by the three 15-year periods, major growth in tissue capacity
can be seen in the past 15 years (2001-2015). In Fig. 6:
* Asia had a large increase in added capacity in the 2001-2015 period.
* Latin America and Africa/Mid-East regions have seen a significant
capacity increase in the 2001-2015 time period.
* Europe and North America regions have seen a slowing in capacity growth with 2001-2015 being the slowest 15-year period for
those regions.
The big driver of the capacity increase in Asia has been China yankee
dryer deliveries. However, there are some manufacturers of yankee
dryer pressure vessels in China that did not participate in the study, so
it is assumed that the number of yankee dryers currently operating in
China is much higher than the current survey data indicates.
Figure 7 shows Asian deliveries (China and non-China) since 1970
by 15-year time period.
The 45-year period analysis of regional deliveries was performed to
look at operating yankee dryers per each region. Although it is difficult
to accurately list operating tissue machines at any given point in time,
the 45-year sum is a close approximation of current operating machines
per region. At least 10 to 20 yankee dryers that were installed before
1970 continue to operate today, and 10 to 20 yankee dryers have needed
replacement since 1970. Also, there are always business reasons that may
necessitate closure or temporary stoppage of tissue machines. Thus, the
accurate number of currently operating yankee dryer tissue machines
is always changing slightly.
Another factor that has increased the usable lifetime of all yankee dryer
cylinders is metallized coatings. Before metallization, the lifetime of a
gray cast iron yankee dryer was limited to the frequency of re-grinding
the shell papermaking surface. The gray cast iron yankee dryers are
