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:
Design pressure: 2.5MPa; Test pressure: 3.75MPa
Design temperature: -35 ℃ ～ + 60 ℃
Transport medium: methanol
Nominal size: DN80
Pick-up form: quick connector
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
