Product introduction:
Loading arm combines rotating joint, which has good performance of loading resisdence, flexible rotation and sealing, with pipeline ,pipe attachment, balance device, support framework and the system of control operation. It is mainly used in the fluid material transmission between tanker and pipeline.
Loading arm is classified as land loading arm and marine loading arm.
Applicable Scope:
Petroleum products such as crude oil, naphtha, gasoline, diesel, kerosene, liquid asphalt,etc.
Liquefied Petroleum Gas, Liquefied natural gas
Strong acid, strong alkali and other liquid chemical products
Other liquid such as edible oil, water, coal slurry and cement.
Product Features:
■Rotating joint and Sealing pieces
Rotating joint is a key component of loanding arm. It is made by stainless steel and alloy steel.
Applying duplex raceway, it can bear harsh axialflow and radial load torque. flexible rotation and unique leakproof structure. Using enhanced PTFE, which is wearable and corrosion-resistant. embedding stainless steel elastic skeleton and polishing treatment to sealing face.
reliable sealing, high strength of withstand voltage, and ?extensive application to manifold medium.
■Diverse types of balance devices and indifferent equilibrium.
A variety of equilibrium modes such as spring brake chamber, cylinder, counterweight, etc. Reasonable designed structure, indifferent equilibrium, and flexible operation
■The large scope of activity, and well-flexibility.
During loading and unloading operations, the equipment can move with marine/track within the rated operating range, exerting its well-flexibility sufficiently.
■Automatic Control, Simple Operation, Safe and reliable
It can used with pneumatic and electro-hydraulic control system, alarming system and anti-static system. It is also operated simply , safe and reliable.
■Long operating life, convenient for repair, the extensive application of medium.
Pipe material could be chosed from carbon steel, stainless steel, low temperature steel, PTFE lined steel,etc. High quality of surface treatment and coating. Possessing excellent corrosion-resistant and weather resistance. The detachable rotating component is extremely convenient for maintaining.
■Complete in specifications, Structural diversity, Strong applicability
There are many specification and form of structure of products in kuangwei petrochemical Machinery m. So it’s? . believable for the customer to choice a suitable products. |
land loading arm（Crane tube ） |
Land loading and arm is used for the top and bottom loading and unloading of various liquids and liquefied gas by highway and railway tankers in open or seal-off state. It is applicable to chemical products such as liquefied gas, petroleum and petrochemical products, acid, alkali, etc.
--used in handling operation on the top or bottom of tankers in the open or seal-off state.
--in the process of loading and unloading, it moves with the tanker in the rated operating range.
--could adopt operation by manual and pneumatic.
-- a variety of ancillary facilities offered be selected and match, in order to realize safe operation
--pipelines could be made by carbon steel, stainless steel, PTFE lined steel, etc.
-- pipeline for liquid phase could adopt the nominal diameter such as 2” 3” 4” 6”, and we also provid other diameters.
-- nominal diameter of return gas pipeline is 1” 2” 3” ,etc
--the range of design temperature is -196C~+300C
--the range of design pressure is PN1.0MPa~PN4.0Mpa |

Model Description
Nominal Diameter--according to liquid phase pipe's diameter: DN50 DN80 DN100
Intended use—AL—used in loading and unloading of the automobile and tanker of train
Site of loading and unloading---1—the top loading/unloading 2---the bottom loading/unloading
Quantity of rotating joints ---4—4 rotating joints 5—5rotating joints
Gas phase tube or no --- 0—no gas phase tube 1—have a gas phase tube
Structural style of liquid phase pipe ---1—upper-fit 2—nether-fit 3—upward-turn 4—downward-turn
Direction of rotating ---R--Right type L--Left type
Exmple:
Top loading arm whose diameiter is DN80, and the direction of rotating is left type with PTFE lined pipe, could be filed as DN80AL1402/L(PTFE Lined)
Top opened loading/unloading arm whose diameter is DN100, and the direction of rotating is right type,could be filed as DN100AL1403/R |
the form of manubrium
1. 90 degree export 2. 45 degree export 3. Shunt cap 4.flange export 5. 90 degree angle of flange export 6. flange export of hard/soft pipe 7. sealing cap of short manubrium export 8. sealing cap /telescopic tube export 9. telescopic tube10. others
Note:
It is the typical structural style of land loading/unloading arm. The key feature of this product is that the design and manufacture is according to technical parameters provided by customers. We could design separately according to customers' field conditions and technical parameters,in order to satisfy the specific requirements. |
