IS 10987 : 1992 Code of practice for design, fabrication, testing and installation of underground/above ground horizontal cyclindrical storage tanks for petroleum products

1 Scope

1.1 This code is intended to provide purchasers andmanufacturers with guidelines in design, fabrication, testing andinstallation of under-ground as well as above-ground horizontalcylindrical steel tanks with flat ends for storage of petroleumproducts.

1.1.1 Provisions of this code may also be applied to design andconstruct tanks for storage of various chemicals having specificgravity less than one. In such cases, special considerationsregarding lining and corrosion allowance shall be made whiledesigning the tanks for intended use.

1.1.2 Provisions of this code are applicable for storage ofproducts under ambient temperature and atmospheric pressureconditions.

1.2 This standard is complementary to IS 800 : 1984 and IS 816 :1969.

1.2.1 Provisions regarding permissible stresses, design,fabrication and erection as included in IS 800 : 1984 shall applyunless specified otherwise in this code.

1.2.2 For provisions regarding analysis for saddle support andassociated local loads, reference shall be made to IS 2825 : 1969.

1.3 The above-ground storage tanks covered in this standard arenot intended for mobile application.

1.4 Unless otherwise stated specifically, provisions, covered inthis standard apply to both above-ground and underground tanks.
