AL1412 closed top loading arm

Composition of the 1412 closed top loading arm

The closed top loading arm consists of five rotating joints, a rotary mechanism, four liquid phases, and one gas phase.The gas phase is generally DN50, and the liquid phase is selected according to the flow rate required by the customer.The gas phase is connected at the transfer using a metal hose to ensure the flexibility of the crane tube.The liquid phase interface of the loading arm is facing downward, and the gas phase interface is facing upwards. Generally, the gas phase will be aggregated on one main pipe.If a single unit is emptied, a flame arrester with a rain cap is required to prevent the pipe from entering the ignition source.There is a conical sealing cap on the vertical pipe. When loading, the vertical pipe is inserted into the top of the tank car, and the sealing cap is compacted at the filling port.Locking the outer arm locking lever(Or the cylinder is pressed tightly. When used in conjunction with oil and gas recovery, it is recommended that the loading arm be added to the cylinder to achieve sufficient sealing.Because the empty tank truck gradually increases the material during loading, the tank tire is flattened and the tank truck is lowered.The sealing cap is not well sealed, and there must be a pressure on the sealing cap by the cylinder to ensure that the sealing cap always keeps up with the filling opening.To achieve effective sealing, oil and gas recovery requires a sealing effect of 90%-95%)After the sealing cap is sealed, the vaporized medium in the tank car can be evacuated through the gas phase pipe on the loading arm or pumped into the oil and gas recovery system.

Loading arm performance

◆    The key piece rotary joint is made of alloy steel and stainless steel.It is processed by precision CNC machine tool and has built-in double raceway support structure.Capable of withstanding harsh axial, radial and moment loads,Flexible, reliable and leak-free.

◆    The seal ring has a unique structure and is made of PTFE reinforced polytetrafluoroethylene.A stainless steel frame is embedded and the sealing surface is polished.Excellent wear resistance, superior sealing performance and reliability.

◆    The spring-cylinder balance system can be balanced at any point, making the alignment operation light and reasonable.

◆    All pressure main pipe welds are argon-arc welded and fully comply with HG/T 21608-96.

◆    Equipped with high-quality and reasonable electrostatic grounding system, the electrostatic resistance is less than 2Ω, and the safety performance is reliable.

◆    The structure is reasonable, with the smallest arm size to achieve the maximum envelope range.

◆    In the loading and unloading operation, the tank truck moves within the normal range and exhibits sufficient flexibility.

◆    The pipe material can be selected from carbon steel, stainless steel, low temperature steel, aluminum, glass reinforced plastic, and lining PTFE.

◆    The surface of the loading arm is sandblasted and rust-removed, using high-quality paint and advanced spraying technology, which not only ensures good appearance quality, but also has strong corrosion resistance.

◆    It is designed according to the left or right type design, and the structural form can also be specially designed.
