Fluid handling arm
Fluid handling arm

One. Overview

The land fluid loading and unloading arm (referred to as crane pipe) is connected in series by a flexible joint with good rotation and tightness to the pipeline, and is used to transfer liquid medium between the tank truck and the trestle storage and transportation pipeline.

◆ Main structure of loading arm:

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.

◆ Product main features:

Scope of application: The liquid loading and unloading arm is connected in series with pipelines, pipe fittings, flanges, ball valves, quick joints and other components with rotary joints that are flexible in rotation, good in tightness and can adapt to harsh environments. It is used for liquid ammonia, liquefied petroleum gas Special equipment for loading and unloading liquefied gas such as propylene and propylene.

two. Functions and features

The land fluid loading and unloading arm is a special device with flexible rotation, good tightness, and adaptability to harsh environments. It is connected to the pipeline in series. It is a special equipment used to transfer liquid or gas products between the loading platform and the road and railway tank cars.

--- For tank cars with open top and sealed or bottom loading and unloading operations;

--- During the loading and unloading process, follow the tanker within the normal range of the tanker's movement;

--- Can be operated manually or pneumatically;

--- Balance can be achieved by spring cylinder

--- There are many accessories to choose from to achieve safe operation or environmental protection;

--- The pipeline can be made of carbon steel, stainless steel or PTFE-lined carbon steel;

--- The nominal diameter of liquid pipeline is 2 ", 3", 4 ", 6"

The design scheme of the oil transfer arm varies according to different requirements and different environments. Therefore, the user should provide the tidal range of the terminal, the tonnage of the ship, the type of liquid, the diameter of the oil transfer arm, the pressure level, and the environmental parameters (wind load, temperature, seismic load). ) And other parameters.
