Product Description
    Liquid chlorine loading and unloading crane pipe, liquid chlorine crane pipe manufacturer, the crane pipe is mainly composed of fixing, rotating, operating, balancing and other mechanisms and tubing. Among them, the slewing mechanism (rotary joint) is made of forged steel or aluminum alloy, with double-row ball bearings and special stainless steel sealing rings. It is flexible in rotation, reliable in sealing performance and durable. Balancing systems include counterweights, torsion springs, compression springs, tension springs and lead screws, as well as hydraulic and pneumatic balances, all of which can be operated with very little force. Lianyungang Asta Petrochemical Equipment Co., Ltd. specializes in the production of crane tubes!

Product Features of Liquid Chlorine Crane Pipe 1.
The rotary joint with double raceway and the sealing ring with elastic card ensure that the loading and unloading medium does not leak;
2. The spring cylinder balancer that balances at any time makes the loading and unloading arm easy to operate and saves effort;
3. During the loading and unloading process, Follow up with the tanker within the normal movement range of the tanker;
4. When the loading and unloading arm is in the receiving state, the locking is parallel to the traveling direction of the tanker, occupying a small space.
Liquid chlorine loading and unloading crane pipe components
1. Column:
In order to rationalize the force on the pipeline, it is used to support the weight of the arm, disperse the load of the rotary joint, and install it stably.
Bolts or welding can be used to assemble the column and the trestle.
2. Inner Arm Lock:
Used to lock the arm in the stowed position when the arm is in this position, which can prevent damage to the arm or surrounding buildings due to windy conditions or non-operating operations.
3. Interface: It is the connection part between the arm and the pipeline. Generally, the flange is connected between the interface and the pipeline.
4. Rotary joint
It is used for the rotation movement of the arm, and meets the normal use range (envelope range). The conventional crane tube adopts 4 or 5 rotary joints to realize the three-dimensional movement and the connection of the flange interface.
5. Inner arm:
The part between the connection interface and the outer arm, which can be rotated on the horizontal plane.
6. Outer arm:
It is the main part of the crane tube, which can rotate 360° in the
horizontal direction and 75° in the vertical direction.
7. Gas phase pipe (AL1412/3 type):
stainless steel metal hose is used to export the volatile gas medium.
8. Vertical pipe: The
loading and unloading arm can be extended into the tanker. The aluminum alloy vertical pipe overcomes the possible harm caused by the collision of steel materials with the tanker.
9. Balance system:
It is used to balance the weight of the outer arm and the vertical pipe, which makes the arm operation flexible and light. The balance system is a spring cylinder, and the spring in the cylinder is a compression spring.
10. Vacuum short-circuit valve/exhaust valve: The
vacuum short-circuit valve ensures that the residual medium is emptied from the crane pipe, and the exhaust valve is used to discharge the gas in the vertical pipe of the unloading crane pipe.
11. Sound and light liquid level alarm (optional): The
liquid level probe is installed on the head of the vertical pipe. When the liquid medium in the tank car approaches the tank mouth, it reminds the operator to close the valve, which can be linked with the control electro-hydraulic valve.
