Translation issues for mating flange and companion flange
Thread Content
The choke valve shall meet the ASME rating 1500 requirement in accordance with the corresponding piping class for the flange design, ensuring that its dimensions match those of the accompanying flange’s PCD and OD. The throttle valve must comply with ASME grade 1500 standards; the flange design should be selected based on the appropriate piping class, so that the dimensions are consistent with those of the associated flange’s PCD and OD. Discussion: Do both mating flange and companion flange mean paired flanges? Does one refer to the flange of the valve itself, and the other to the matching flange on the pipeline? What is the best English translation for the flange of the valve itself?
Yes, both mating flange and companion flange can be understood as paired flanges, and they generally refer to two flanges that are used together in a connection. Generally, a mating flange refers to the flange that fits directly with another component, while a companion flange is the flange used for connection or fitting within an installed system. In this context, the mating flange likely refers to the flange on the throttle body, while the companion flange refers to the flange that matches it in the piping system. Therefore, if referring to the flange of the throttle valve itself, \"mating flange\" is a more appropriate term. When describing the flange on the pipe connected to the throttle valve, \"companion flange\" is a more precise term. .
I tried to reply using software. Mating Flange: The connection flange for two ordinary pipes in a piping system. Companion Flange: A flange pre-installed on the valve, used to connect pipes. In summary, the Mating flange is a universal mating flange, while the Companion flange is a mating flange designed specifically for certain devices

The throttle valve should meet the requirements of ASME 1500 pound class, conform to the corresponding pipe class, and be used in conjunction with flange design to ensure that its dimensions match those of the mating flanges, including the outer diameter and bolt hole center distances.
“\"Used in conjunction with flange design\" – does this refer to the flanges that are built on both sides of the throttle valve?
As a supplementary note: this throttle valve is generally of API 5000# standard. Does this sentence mean that the throttle valve needs to be custom-made? Although it is of API5000# standard, its flange dimensions should be based on those specified in ASME 1500#?

It is necessary to coordinate with the pipe flanges; 5000psi corresponds to API 6A valves paired with API standard 6B flanges, while pipes typically use 1500LB flanges according to ASME B16.5 standards. The two have different dimensions and therefore cannot be used together.
