What are the principles to be followed when selecting the crane crane tube?

The development of unloading crane pipes is more robust due to the Internet. In the petrochemical industry, there are more varieties of liquid products and different properties of chemical materials. The types of cars, train tankers, or tankers used to ship these chemical materials vary greatly. , And the size of the slot is different, the loading and unloading methods also have two different modes of top and bottom. Therefore, it should be reasonable to choose the form of unloading crane pipe according to various actual conditions, which is very important for safety production. What are the principles to be followed when selecting the crane crane tube?

When loading liquefied petroleum gas or liquefied gas materials, a closed truck crane tube must be used.

Under normal temperature storage and loading and unloading conditions, when the saturated vapor pressure approaches or exceeds 0.1 MPa (absolute pressure), a closed unloading crane tube must be used.

Under normal temperature storage and loading and unloading conditions, the materials are volatile liquids, and they are flammable, explosive, and polluting the environment or harming the human body. It must use a closed unloading crane tube.

The material is a volatile liquid, and when the volatile gas has a certain recovery value, a closed dump truck must be used.

When unloading a tanker or ship, when using gas-phase supercharging or vacuum pumping, a closed-type unloading crane tube must be used.

For corrosive materials, in order to prevent material splashing or to ensure personal safety, a closed dump truck crane should be used.

For the loading and unloading of low-volatility and non-hazardous general liquid materials, an open crane pipe can be used.

When loading low-volatile liquid materials, it can be used in the form of a plug-in short vertical pipe, such as a 90 ° flat outlet or a 45 ° oblique outlet.

The above is a brief description of the principles followed by the editor. You can simply take a look. The content is for reference only. If you need to consult, you can contact us.
