General principles of transfer sizes Do from one measurement system to another
In water and gas supply are widely used steel pipe, whose diameter is indicated in inches (1″, 2″) or fractions (½″, ¾″). If you measure the pipe diameter is 1″, you’ll get 33.5 mm, which of course corresponds to 1″ (25.4 mm). For installation of pipeline, fittings, where the size is designated by inches, is not necessarily a problem, but replacing the steel «inch» pipes for plastic, copper, stainless, you must consider the mismatch of names and designations in real inches and metric dimensions.
If this is the correct designation of pipeline systems in units of nominal bore DN (Dn). Nominal diameter corresponds to the diameter of the lumen of the pipe member. It has no units and must be an integer, and the step of conditional pass is selected so that the pipeline capacity was increased by 40…60% increase in the index of Du. To determine the exact metric sizes it is necessary to use the table.
At docks steel tubing with a plastic or replacement of one to the other is a standard transition elements. Difficulties arise when using copper, aluminium, stainless steel pipes, which are manufactured to metric standards. In such cases it is necessary to consider the real metric size pipe not only external but also internal.
To by pipe with any metric or inch sizes for the price the manufacturer suggests the company AVEK global. The supplier guarantees the timely shipment of products to any address set by the client.
