loading arm

Land loading arm using swivel joint with a variety of characteristics, such as flexible rotation, good sealing, and adaptability to harsh environments,which are connected in series with pipelines and are used for special equipment for transporting liquid or gas products between a loading platform and a road/railway tanker. 

1.For tank top open and sealed or bottom loading and unloading operations;

2.During the loading and unloading process, follow the tanker within the normal movement range of the tanker;

3.Manual or pneumatic operation can be used;

4.Balance can be achieved through spring cylinders;

5.There are a variety of ancillary facilities available for matching to achieve safe operation or environmental protection;

6.The pipeline can be made of carbon steel, stainless steel or PTFE lining carbon steel;

7.Nominal caliber for liquid pipes is 2'., 3", 4". Other calibers are also available. Nominal calibers for gas return pipes are 1", 2", 3", etc.

8.he design temperature range is -196°C~+2500°C;

9.The design pressure is PN1.0MPa~PN4.0MPa

Land loading and unloading arm can be divided into top and bottom loading arms.

	Al1401 heating top loading arm It is suitable for loading trucks and trains with poor flow medium such as crude oil, residual oil and asphalt. The heat transfer medium can be steam or heat transfer oil, or electric heat tracing
	Al1402 top loading arm Suitable for trucks and train top loading of gasoline, coal, diesel, liquid chemical media.
	Al1512 top loading arm It is suitable for loading and unloading trucks and trains on two highly volatile chemical media such as liquefied petroleum gas, liquid ammonia, liquid chlorine and other gas and liquid
	AL1403 top loading arm Suitable for trucks, train top unloading and loading of gasoline, coal, diesel, liquid chemical media.
	AL1411/1412 Mission top loading arm It is suitable for trucks and trains with volatile and toxic media. It can be used to recover the volatile media
	AL2503 bottom loading arm It is suitable for the loading and unloading of trucks and trains in crude oil, residual oil, chemical media, coal water slurry and other media.
	AL1402F1 PTFE heating top loading arm It is suitable for loading trucks and trains with strong corrosive media such as acid and alkali
	AL2543 bottom loading arm Suitable for liquefied petroleum gas, liquid nitrogen, dimethyl ether and other gas-liquid two high volatile-type chemical mediumtrucks, trains at the bottom loading and unloading
	API bottom loading arm      API bottom compact loading arm, as long as it is used for high-volatility medium such as gasoline and diesel, naphtha and various light hydrocarbons; it adopts the international standard API interface to connect with the bottom of the tank truck for loading, which can realize quick docking and increase Safety, meet environmental requirements, prevent the accumulation of static electricity and the volatilization of gasoline.

 Special loading arm project case

（1）Ultra-low temperature loading arm (such as LNG loading arm)

Ultra-low temperature loading arm are mainly used for low temperature type media, such as LNG, liquid nitrogen, liquid oxygen, ethylene and other media. The following is mainly based on LNG loading arm:

(2) Loading arm for oversea markets

The loading arm of special joints for oversea markets have the same main structure as the Chinese standard loading arm. The main difference is the joints with the tanks. According to different national standards, the following picture:
