Scope

NB/T 47041-2014 is the English-translated version of 塔式容器.

NB/T 47041-2014 is the Chinese standard "Vertical vessels supported by skirt". Its scope clause reads: This Standard specifies design, fabrication, inspection and acceptance requirements for metallic vertical vessels.

The application scope of this Standard is as follows: a) The design pressure of steel vertical vessels supported by skirt is no greater than 35 MPa and the design pressure of vertical vessels made from other metallic materials shall be in accordance with the requirements of relevant standards; b) The design temperature range falls in the allowable application temperature range of metallic materials; c) Skirt self-support metallic vertical vessel with the ratio of height H and average diameter D greater than 5.

Skirt self-support metallic vertical vessel with the ratio of height H and average diameter D no greater than 5 may be designed by reference to Appendix E. This Standard is not applicable to the following vertical vessels: a) Vertical vessel accompanied with bracing device; b) Coupled in-line vessel or vessel group integrated by operating platform; c) Vertical vessel with jacket; d) Cast iron and nonmetallic vertical vessel. Its clauses include terms and definitions.
