For example, UNIT STRENGTH is defined as load in Newtons per millimeter (of laminate width) for a layer consisting of 1 kg of glass per square meter, i.e., the unit is N/mm per kg/m2 glass. It is property per unit width, per unit mass of reinforcement. NEW LOAD UNITS: It is to avoid the uncertainty associated with specifying the thickness alone, that BS4994 introduced the concept of 'unit properties'. An earlier version of the specification was BS 4994:1973. The choice of resin is based on the chemical corrosion requirement of the equipment. These mats are laid on the mold and impregnated with 'initiated' resins like polyester, epoxy, vinyl ester, bisphenol epoxy vinyl ester, etc. , are used as common thermoplastic liners.įRP (GRP): Glass mats in the form of chopped strand mat and woven roving is most common in hand lay-up method. The choice of thermoplastic is based on the chemical corrosion requirement of the equipment. This thermoplastic liner is not considered to contribute mechanical strength.įRP which is constructed over this lining provides the strength requirements for materials to withstand design conditions like pressure, vacuum, hydrostatic load, etc.
DUAL LAMINATE: A lining material, preferably 3mm to 5mm thick sheet functions as a corrosion barrier. Dual laminate construction, simple FRP with glass mats, or a combination of unidirectional filament winding are common. With the publication of BS EN 13121-3, BS 4994:1987 Specification for design and construction of vessels and tanks in reinforced plastics is declared obsolescent, which will still cover those tanks still in service as tanks made from GRP are generally accepted to have a long working life.
