West changed to develop the first AC graded controllable reactor through factory inspection
On June 1, the first 50Mvar/500kV AC class-controlled single-phase shunt reactor in China passed the factory test in Xi'an Xidian Transformer Co., Ltd. The performance indicators of this product are better than the agreement requirements and reach the international advanced level.
The 50Mvar/500kV AC class-controlled single-phase shunt reactor is a group of three, which was developed for the State Grid Corporation Shandong Zhangzhou 500kV switch station, which indicates that the company continues to maintain its leading position in the domestic reactor manufacturing field. The product has the advantages of convenient capacity adjustment, fast response time, no harmonic generation, low noise, vibration and loss index. In the long-distance transmission for ultra-high voltage and ultra-high voltage power grids, the superiority is more prominent, which is of great significance to the localization of electric equipment in the country's future construction of a million-volt UHV power grid.
The company's reactor products have always dominated the domestic market. Last year, 136 reactor products were successfully produced. Among them, 100Mvar/750kV single-phase shunt reactors are the first high-voltage products in China with independent knowledge. This year, 162 units have been scheduled.
ASME B16.5 Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings. Included are:
(1) flanges with rating class designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanges with rating class designation 2500 in sizes NPS 1/2 through NPS 12, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;
(2) flanged fittings with rating class designation 150 and 300 in sizes NPS 1/2 through NPS 24, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;
(3) flanged fittings with rating class designation 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanged fittings with rating class designation 2500 in sizes NPS 1/2 through NPS 12 that are acknowledged in Non-Mandatory Appendix E in which only U.S. Customary units are provided.
B16.5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.
This Standard is to be used in conjunction with equipment described in other volumes of the ASME B16 Series of Standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.
Careful application of these B16 Standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.
Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of valves with pressure equipment, plus all potential governing entities.
