Adjustable spring support bracket Huaneng Pipeline Equipment damping spring hanger

Recently some customers call me Gongyi City Huaneng Pipeline Equipment Manufacturing Co., Ltd., ask our pipe hangers perform what specific standards, applicable rules of pipe supports my company also made a relevant understanding. This will be our special pipe hangers use standards and applicable specifications published as follows: GBi7116-1997 "pipe hangers" M55 SPSB, SPG9, SP89 "pipe hangers)) ASME ASME" Boiler and Pressure Vessel Code "B3f .1 "Power Piping" "Boiler and Pressure Vessel Code" VIII) Nuclear Power Plant NB supports RCC} M "PWR nuclear island mechanical equipment design and construction rules" H chapter support GBi5U} 1998 "steel pressure vessel "DLIT SQS} -1996" thermal power plant steam piping design technical requirements "DLIT 1113} 20} 9" power plant pipe hangers and acceptance procedures "applicable rules ECEPDI 1983 edition of" pipe hangers Handbook "Northwest Power Institute 1983 edition of "pipe hangers Manual" J} IT 813 D.1 "constant force spring hanger" J} IT 8130.2 "variable spring hangers" "SPEC series pipe hangers Handbook" Jiangsu Power Equipment Ltd. constant force spring hanger HCIT 200664-1998 "chemical variable force spring hangers" spring hangers in addition to meet various functional requirements, but also hope that it is within the operating conditions and lifetime use of a sufficient strength, does not produce any permanent deformation, but should also be light weight, small size, easy to manufacture and inexpensive. Some of these conflicting requirements, such as requiring sufficient strength tends to cause weight gain and increase in cost. Sometimes to fully meet these requirements is difficult. Therefore, in spring hanger design should first meet the functional requirements, followed by strength requirements, and finally on account of its economy. Usually spring hanger design steps should be: according to the requirements of use, select suitable spring shape, type and end structures. According to the given spring hanger position for example to allow the maximum diameter, minimum diameter, free height and deformation amount of the coil spring; plywood spring length, width _ the number plate, arc deflection and free state Higher) fix a spring contour size. Depending on conditions (such as temperature, ambient media, magnetic requirements for selecting suitable materials according to the load characteristics of the spring hanger conditions of use (for example, static load, dynamic load or impact load, repeated load or vibration loads, etc. ) determine the allowable stress, calculate a variety of specific geometric parameters of the spring and the manufacturing method includes a heat treatment procedure, including, where two of the plumbing system in spring specified requirements have not changes, so spring allowable stress design workers hanger spring material primarily choose to determine the allowable stresses calculate various specific geometry and manufacturing methods, the Wei material means spring hangers in a specified condition without fail the maximum allowable stress the long-term use.
