Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
In 1970, O.P. Jindal founded a mini steel plant named Jindal Strips Limited at Hisar. [10] [8] [4] It started manufacturing hot rolled carbon steel coils, plates, slabs and blooms. It was the beginning of the story for Jindal Stainless. Over the years, the company expanded its capacity at Hisar. In 2002, Jindal Strips was restructured as Jindal ...
Jindal Institute of Power Technology (JIPT) JIPT was established to develop a pool of technically trained power plant professionals for power utilities in India and abroad. The course authorizes the pass-outs to operate or undertake maintenance of any part or whole of generating stations of capacity 100 MW & above together with the associated ...
Later, in 1994, Jindal Vijayanagar Steel Limited (JVSL) was set up with its plant located at Toranagallu in the Bellary-Hospet area in the State of Karnataka, the heart of the iron ore belt and spread over 10,000 acres (40 km 2) of land. It is well connected to both the Mormugao Port and Chennai Port and is 340 kilometres from Bangalore. It is ...
For both of these rules of thumb (85%/90% and major minus pitch), the tap drill size yielded is not necessarily the only possible one, but it is a good one for general use. The 85% and 90% rules works best in the range of 1 ⁄ 4 –1 in (6.4–25.4 mm), the sizes most important on many shop floors. Some sizes outside that range have different ...
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [ 15 ] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size.
Because of the pipe wall thickness of Schedule pipe, the actual diameter of the NPT threads is larger than the Nominal Pipe Size diameter, and considerably so for small sizes. Pipe of a given size in a different Schedule than Schedule 40 provides a different wall thickness while maintaining the same outside diameter and thread profile as ...
For pipe sizes of NPS 14 inch (DN 350) and greater the NPS size is the actual diameter in inches and the DN size is equal to NPS times 25 (not 25.4) rounded to a convenient multiple of 50. For example, NPS 14 has an OD of 14 inches or 355.60 millimetres, and is equivalent to DN 350.
