GB50235-2010, the Code for Construction of Industrial Metal Piping Projects, specifies in clause 7.12.7 that cast iron, lead, aluminum, and large-diameter pipeline valves shall be equipped with dedicated supports. What exactly are meant by large-diameter pipeline valves? What size constitutes a large diameter? Is there any clear specification, or does it mean that any valve that already has supports needs to have additional support as well?
According to the provisions of GB50235-2010 \"Code for Construction of Industrial Metal Piping Projects\": 7.12.7 Cast iron, lead, aluminum, and large-diameter pipeline valves shall be equipped with dedicated supports. The installation of specialized supports should be determined based on the type, size, operating pressure of the valve, as well as the specific conditions of the pipeline. Regarding the “large-diameter pipeline valves” mentioned here, the standards do not specify a precise diameter value to define what constitutes a large diameter. This usually refers to the situation in such piping systems where, due to the large weight of the valves themselves, as well as the high torque or pressure that may arise, additional support is needed to ensure the stability and safety of the system. Such valves generally refer to those with a larger nominal diameter, but the standards do not specify an exact value for this nominal diameter. In actual construction, it is necessary to refer to the engineering design documents and the manufacturer’s recommendations in order to determine specifically whether a special support is required for the valve. Design documents typically provide guidance on whether valve supports are necessary, based on the specific parameters of the pipes and valves (such as nominal diameter, pressure rating, material, operating conditions, etc.). If the valve body is equipped with supports, it is possible that the manufacturer has already taken this issue into account; however, whether separate support is needed still has to be determined based on the actual conditions and engineering design requirements. In general, in the absence of specific dimensions, whether to install dedicated brackets should be determined based on the actual conditions of the valve and the requirements of the project; it is recommended to consult the design agency or make a decision based on the manufacturer’s suggestions. If you have any questions, you can also consult relevant professionals for detailed guidance. .
Take a look at the old five major pipeline support standards; they contain information on valve supports
Hello, could you please provide the standard name or standard number? Thank you!
