Scope
GB/T 17261-2011 is the English-translated version of 钢制球形储罐型式与基本参数.
GB/T 17261-2011 specifies the types and basic parameters of steel spherical storage tanks supported by columns tangent to the equator, used to store gases and liquids in the petroleum, chemical, metallurgical and city gas industries; the tank structure must also comply with GB 12337.
It covers two families, orange-peel (petal) tanks and mixed-type tanks, each with three to seven shell belts, and shows the belt names and designations and the polar plates in twelve figures.
Two tables give, for each nominal volume from 50 m3 to 25000 m3, the inner shell diameter or foundation centre-circle diameter, the geometric volume, the height from column base plate to equator, the number of belts and columns, and the central angle and number of plates of each belt.
It replaces GB/T 17261-1998: the maximum volume rises from 10000 m3 to 25000 m3, tank types from 8 to 10 and volume sizes from 14 to 20, the equator height is raised by 200 mm or 400 mm, and belt divisions are adjusted to current plate sizes.

Foreword
This standard replaces GB/T 17261-1998. Compared with GB/T 17261-1998, the main changes are as follows:
- the maximum nominal volume has been extended from 10000 m3 to 25000 m3;
- the number of spherical tank types has been increased from 8 to 10, and the number of tank volume sizes from 14 to 20;
- the distance from the underside of the column base plate to the equatorial plane of the spherical shell has been raised by 200 mm or 400 mm;
- the number of shell belts, the number of plates in each belt and the central angle of each belt have been adjusted according to the available steel plate sizes.
This standard was proposed by and is under the jurisdiction of the National Technical Committee on Boilers and Pressure Vessels of Standardization Administration of China (SAC/TC 262).
