Omfang

This specification covers cylindrical tanks fabricated by contact molding for above-ground vertical installation, to contain aggressive chemicals at essentially atmospheric pressure, and made of a commercial-grade polyester or vinyl ester, resin. This specification does not cover the design of vessels intended for pressure above hydrostatic, vacuum conditions, except as classified herein, or vessels intended for use with liquids heated above their flash points. The tanks are classified as type I and II according to the operating pressure or vacuum levels, and the safety factor required for external pressure. The tanks are further classified as grade 1 and 2 according to the generic types of thermoset resin. The resin used shall be a commercial grade, corrosion-resistant thermoset. The reinforcement should be a chopped-strand mat, a nonwoven biaxial or unidirectal fabric, a woven roving, or a surface mat. Materials shall be tested and the individual grades shall conform to specified values of design requirements such as straight shell, external pressure, top head, bottom head, open-top tanks, joints, fittings, hold-down lugs, and lifting lugs; laminate construction requirements such as structural tank, joints, and fittings and accessories; and other requirements such as physical properties, chemical resistance of resin, glass content, tensile strength, flexural properties and degree of cure. The dimensions and tolerances, as well as the workmanship, finish and appearance are also detailed.
