We can carry out professional custom design and manufacture according to different specifications. We can provide full technical guidance and professional installation. Welcome to inquire.

Methanol (CH3OH) is a colorless, volatile liquid with an alcohol odor. The lowest dose of oral poisoning in humans is about 100 mg / kg of body weight, and oral intake of 0.3 to 1 g / kg can be fatal. It is used in the manufacture of formaldehyde and pesticides, and is used as an extractant for organics and a denaturant for alcohol. The finished product is usually made by reacting carbon monoxide with hydrogen. Methanol is a toxic medium and requires special loading crane tubes for loading and unloading operations.

Usually the crane pipe model is AL2503, the letter AL stands for land liquid loading and unloading arm, the first digit 2 represents the bottom loading and unloading, the second digit 5 represents the number of rotary joints of the liquid phase pipe is 5, and the third digit 0 represents the gas phase pipe. The fourth digit 3 indicates that the liquid phase tube is a flip-up type.

Methanol crane tube parameters:

The main structure of the methanol crane tube:

Column: Supports and supports the turning moment when the arm is deployed

Rotary joint: It is composed of rotating parts and seals. It is mainly used to connect different components of the liquid loading arm for relative rotation and can bear the load.

Inner arm: used to connect the conveying pipe and connect with the outer arm

Outer arm: It can rotate in the range of horizontal and vertical planes. It is mainly used for loading and unloading parts that adjust the working position with the tank car and tank ship

Balancer: A component used to balance the torque of the outer arm

Ball valve: manual control loading and unloading switch

Quick Connector

Main material of methanol crane tube:

Piping: carbon steel or stainless steel

Ball valve: stainless steel

Rotary joint: outer ring 30CrMo or 45 steel, inner ring 304

Main sealing ring: PTFE, skeleton 304
