BOS 94-2: 2016 ed.2

Description

This part of BOS 94 specifies requirements for pipes, fittings and joint assemblies manufactured from glass-fibre-reinforced thermosetting resins a) for the conveyance of liquid or gas hazardous chemical substances in industrial applications, b) that are designed for general operation under conditions of internal pressure or vacuum (to a negative pressure of -15 kPa) but can also be used for non-pressurized applications, c) in systems where the product of maximum allowable pressure (PS), in bar, and nominal diameter (DN), in millimetres, does not exceed the value of 6 000 for liquids and gases, and d) that can be lined or unlined. This part of BOS 94 does not cover pipes, fittings and joint assemblies for the conveyance of steam or steam condensates, pipes of ribbed construction, or systems for which the main design feature is stiffness (for example, where the pipes are to be buried, or are particularly large). NOTE If so agreed upon by the parties to a contract based on this Botswana Standard, the relevant technical requirements of this Botswana Standard can be applied to GRP pipes of diameter or pressure class other than those explicitly specified.
