Help: Flange and pipe diameter at the dump port of a tank truck
Thread Content
Dear seniors and experts: What are the diameter of the discharge port and the size of the connection flanges for the tank trucks commonly used in China at present? Upon arrival at the site, the material is unloaded into the on-site storage tank; what size connection flanges should be used for the tank? Are there any standards? Thank you! If there are standards, could you please provide the standard numbers? Thank you
The liquid-phase pipelines for liquefied gas, propylene, etc., are DN50, while the gas-phase pipelines are DN25
It’s best to confirm this with the property owner; it’s not appropriate to assume that it’s the same everywhere in the country
It is generally DN50 PN16/PN25, in accordance with GB\HG standards and others. In practical use, the bolt holes on this flange are enlarged to prevent installation difficulties resulting from differences in standards. I have been working in the LNG industry for many years, dealing with the sales of gasification products and pressure regulation products; technical services and support are available upon request.
It is best to obtain these data from the owner. After all, the country is not yet fully unified. Due to the different origins of the vehicles, the relevant parameters also vary.
Thank you all for your replies, thank you!
I have seen dump truck unloading ports with a DN80 size, in the form of quick connectors.
That must be a tank truck for oil products or chemical substances
Currently, the commonly used size for oil pipelines is DN100; the lower connection ports are usually equipped with breakaway valves and dry valves.
