Automatic crane pipe is a new type of liquid loading and unloading equipment which is very easy to use and cut safely. as the name suggests, crane pipe is a kind of telescopic pipe, which is mostly used for liquid loading and unloading of petroleum and chemical wharf, such as oil, water and so on. 

Common specifications 8 "- 20" 

Automatic crane pipe is a special equipment in the process of fluid loading and unloading in petrochemical industry. 

It uses rotating joint to connect with rigid pipe and elbow to realize the movable equipment for transmitting liquid medium between train, automobile tank car and trestle storage and transportation pipeline, which replaces the old hose connection and has high safety. 

Flexibility and long life and other characteristics. 

The products conform to the standard of GBJ74-84 "Code for Design of Oil Depot". It is an ideal special equipment in oil receiving and receiving process, and can also be widely used in chemical industry and other industries to send and receive all kinds of liquid raw materials.

Crane pipe: car loading and unloading crane pipe, train loading and unloading crane pipe, aircraft loading and unloading crane pipe, bucket crane pipe and so on. 

Railway and highway loading and unloading oil crane pipe is mainly used in the special equipment of loading and unloading fluid operation of railway tank truck and highway oil tank car. 

From the type of loading and unloading can be divided into upper loading and unloading and lower loading and unloading. 

It can transport petroleum products such as crude oil, gasoline, diesel oil and lubricating oil, as well as concentrated sulfuric acid, liquefied natural gas, liquefied petroleum gas, dissolved sulfur, asphalt, carbon disulfide and other chemical products. 

. 

The crane pipe is mainly composed of fixing, rotating, operation, balance and other mechanisms and tubing. 

Among them, the rotary mechanism (rotary joint) is meticulously manufactured with forged steel or aluminum alloy, with multiple ball bearings and stainless steel special sealing ring, which has the advantages of flexible rotation, reliable sealing performance and durability. 

The balancing system has the types of counterweight, torsional spring, compression spring, tension spring and screw, as well as hydraulic and pneumatic balance, all of which can be operated with very little force.
