Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow ? liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members. There are three basic types of plastic pipes: Solid wall pipe Extruded pipes consisting of one layer of a homogeneous matrix of thermoplastic material which is ready for use in a pipeline Structured wall pipe Structured-wall pipes and fittings are products which have an optimized design with regard to material usage to achieve the physical, mechanical and performance requirements. Structured Wall Pipes are tailor made solutions of piping systems, for a variety of applications and in most cases developed in cooperation with users Barrier pipe Pipe incorporating a flexible metallic layer as the middle of three bonded layers.
To define and secure boilers safely, some professional specialized organizations such as the American Society of Mechanical Engineers (ASME) develop standards and regulation codes.
When water is converted to steam it expands to over 1,000 times its original volume and travels down steam pipes at over 100 kilometres per hour.Because of this, steam is a great way of moving energy and heat around a site from a central boiler house to where it is needed, but without the right boiler feed water treatment, a steam-raising plant will suffer from scale formation and corrosion.
At best, this increases energy costs and can lead to poor quality steam, reduced efficiency, shorter plant life and unreliable operation.At worst, it can lead to catastrophic failure and loss of life.
The Hartford Loop was invented in 1919 by the Hartford Steam Boiler and Insurance Company as a method to help prevent this condition from occurring, and thereby reduce their insurance claims.Źródło: https://en.wikipedia.org/wiki/Boiler#Safety
Plumbing code is a code that provides regulations for the design, installation and inspection of building plumbing and sanitary systems. In the U.S., jurisdictions enact their own codes, some of which are based upon model plumbing codes.1 The most widely adopted plumbing code in the United States is the International Plumbing Code published by the International Code Council (ICC). This code is also used as the basis for the plumbing code of some other countries. Another model plumbing code published in the United States is the Uniform Plumbing Code published by IAPMO.Źródło: https://en.wikipedia.org/wiki/Plumbing_code.
