Reducing fittings Clause Samples

The 'Reducing fittings' clause defines the requirements and standards for the use of pipe fittings that connect pipes of different diameters within a system. It typically specifies the types of reducing fittings permitted, such as concentric or eccentric reducers, and may outline acceptable materials, installation methods, and pressure ratings. By establishing clear guidelines for these components, the clause ensures compatibility and safety in piping systems, preventing leaks or failures that could arise from improper connections.
Reducing fittings. Where fittings have reducing ends or branches they are described as 'reducing'. In the case of pipes with diameters not exceeding 60mm only the largest end or branch size is given. Should the Contractor wish to use other fittings and bushes or reducers he may do so on the understanding that no claim in this regard will be entertained. In the case of pipes with diameters exceeding 60mm all sizes are given and no claim for extra bushes, reducers, etc will be entertained.
