The vapor phase pipe is a part of the loading arm designed to balance the air pressure inside storage tanks and transportation equipment. Its core function is to prevent medium leakage or equipment damage caused by pressure differences. In emergency situations, such as pipeline rupture or valve failure, the vapor phase pipe can act as a safety pressure - relief channel to release excess pressure.
For volatile media like LPG and liquid ammonia, the vapor phase pipe can reduce the evaporation loss of the medium during the loading and unloading process. This not only cuts down on environmental pollution but also lowers safety risks. Moreover, by maintaining a stable pressure environment, it helps to ensure the smooth progress of the entire loading and unloading operation. It can also assist Vid minskning av genereringen av luftfickor i systemet, som annars kan störa det normala flödet av mediet . I vissa fall kan det anslutas till gasåtervinningssystem, vilket möjliggör insamling och återanvändning av flyktiga gaser, vilket är i linje med begreppet miljöskydd och kostnad - effektivitet .}}

The liquid phase pipe is the part of the loading arm used for transporting liquid media. Its core function is to achieve the transfer of liquid media from storage tanks to transportation equipment (such as tank trucks, oil tankers) or in the reverse direction. The liquid phase pipe is directly connected to the liquid phase interfaces of the storage tank and the transportation equipment, ensuring the smooth flow of the liquid medium during the loading and unloading process .
Konstruktionen måste ta hänsyn till de fysiska egenskaperna hos mediet, såsom viskositet och densitet . till exempel för ett medium med hög viskositet, om rördiametern är för liten, kan det leda till långsamt flöde och till och med blockering; while for a medium with low density, too fast a flow rate may cause problems. This is to prevent static accumulation or pipeline vibration caused by excessively fast flow velocity. Static accumulation may cause sparks and pose a danger when dealing with flammable media, and pipeline vibration may damage the pipeline connection and affect the service life. The end of the liquid phase pipe is Vanligtvis utrustat med en dropper eller en speciell led . Detta säkerställer att det inte finns någon rest av vätska efter att lastning och lossning har slutförts, vilket minskar materiella förlust och miljöföroreningar risker . Dessutom, en del avancerad flytande flytande design och obehörighet kan integrera flödesflödet - styra ventiler eller flöde - mätning av apparater, som hjälper till att hjälpa till att tillverka till att hjälpa till att hjälpa till att tillverka till att ACTILLER AONTAL ATT ACTALT CONTROLL Den mängden som är mäter i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Monitor i Mannen, tid .
In general, the vapor phase and liquid phase pipes are complementary to each other. During the loading and unloading process, the liquid phase pipe and the vapor phase pipe work in coordination. By balancing the pressure, they avoid over - pressure or negative pressure in the pipeline, ensuring the safety of the operation. For example, when liquid is pumped into a transportation vehicle through the liquid phase pipe, the air in Fordonet måste släppas ut genom ångfasröret; otherwise, the pressure inside the vehicle will increase, which may cause leakage. Conversely, when unloading liquid from the vehicle to the storage tank, the vapor phase pipe can supplement the gas to balance the pressure reduction in the tank, preventing the tank from being deformed due to negative pressure. Their coordinated operation is the key to ensuring the efficient, safe, and environmentally friendly loading and unloading of liquid media in gas stations and oil Depots .
