Product Description
LPG bottom loading arm is specialized equipment designed for the efficient transfer of liquefied petroleum gas. As essential fluid transfer equipment in the petrochemical industry, it facilitates the safe movement of fluids such as petroleum, LNG, LPG, chemicals, gas, and oil between piping systems and tankers.
The system primarily consists of core components including arms, swivel joints, a spring balance system, flanges, vapor cones, vacuum breaker valves, drop tubes, and couplings.

Frequently Asked Questions
What is the primary use of an LPG bottom loading arm?
It is primarily used in the petrochemical industry for transferring liquefied petroleum gas (LPG) and other fluids like LNG, chemicals, and oil between pipe systems and tankers or railcars safely.
What materials are available for the loading arm construction?
Loading arms can be manufactured using carbon steel, stainless steel, or aluminium, depending on the chemical properties of the fluid being handled and the client's requirements.
Can the loading arm accommodate tanker movement?
Yes, the design allows the arm to follow the movement of the tanker or railcar within a specific definite range during the loading or unloading process.
What are the design pressure and temperature ranges?
The standard design pressure ranges from -0.06Mpa to 6.0Mpa, and the design temperature range is between -196°C and 250°C, making it suitable for cryogenic or high-heat applications.
How is the balance of the loading arm achieved?
The balance of the arm system is typically achieved through a weight stack, a spring cylinder system, or pneumatic support to ensure smooth and easy handling by operators.
Are there different connection types available?
Yes, common connection types include open connections and quick coupling (closed) systems, depending on whether vapor recovery or environmental protection is required.
