Liquid ammonia crane tube
Liquid ammonia crane tube

Ammonia is an important chemical raw material. For the convenience of transportation and storage, liquid ammonia is usually obtained by pressurizing or cooling the gaseous ammonia. Liquid ammonia has a strong pungent odor. It is a corrosive and volatile medium. It needs a special loading crane tube for loading and unloading operations. The liquid ammonia crane tube is used as the crane tube for liquid ammonia loading and unloading operations. .

product structure:

1. Pillar: It plays a supporting role and can withstand the turning moment when the arm is deployed.

2. Inner arm: the basic component of arm movement and conveying medium.

3. Outer arm: the basic component of arm movement and conveying medium.

4. Outreach arm: It can feed the medium into the tanker.

5. Spring cylinder balance system: balance the heavy moment of the vertical pipe and the outer arm, and reduce the resistance of the outer arm to move up and down.
