Importance of Pipeline Standards
Standards provide people and organizations with a basis for mutual understanding, and are used as tools for seamless communication and manufacturing criteria.
Standards have been everywhere and they play an important role in the economy by establishing set procedures for following established procedures and norms for excellence. Some of the important benefits and advantages of pipeline components and pipelines standards are as following:
They facilitate business interaction. They enable companies to comply with relevant laws and regulations. Also, they play an important role in speeding up the introduction of innovative products to market. They offer interoperability between new and existing products, services and processes.
Some of the important pipeline components standards are mentioned as following:
ISO 9080:2003: It describes a method for estimating the long-term hydrostatic strength of thermoplastics materials by statistical extrapolation.
ISO 2507-1:1995: The method is applicable to all types of thermoplastics pipe at applicable temperatures. It was developed on the basis of test data from pipe systems. pecifies method that is based on determining the temperature at which a standard indenter, under a force of 50 N +/- 1 N, penetrates 1 mm into the surface of a test piece cut from the wall of a pipe or fitting while the temperature is raised at a constant rate.
The method specified is based on determining the temperature at which a standard indenter, under a force of 50 N ± 1 N, penetrates 1 mm into the surface of a test piece cut from the wall of a pipe or fitting while the temperature is raised at a constant rate. Is applicable only to thermoplastics materials for which it is possible to measure the temperature at which the rate of softening becomes rapid. Is based on ISO 306:1994 which, however, applies to materials in the form of sheets.
ISO 21138-2:2007, together with ISO 21138-1, specifies the definitions and requirements for pipes with a smooth external surface (Type A), fittings and systems based on unplasticized poly (vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping in the field of non-pressure systems for underground drainage and sewerage.
ISO 21138-2:2007 specifically refers to PVC, PP and PE materials ISO 21138-2:2007 specifies test methods and test parameters. ISO 21138-2:2007 covers a range of pipe and fitting sizes, materials, pipe constructions, and nominal ring stiffness, and gives recommendations concerning colours. In conjunction with ISO 21138-1, it is applicable to PVC-U, PP and PE structured-wall pipes and fittings, to their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for the transport of drainage and sewage. ISO 21138-2:2007 is applicable to PVC-U, PP and PE structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints.
