Bottom Hose Loading Arm

Key Features of Bottom Hose Loading Arms:

1. Ground-Level Safety

Connecting at the bottom keeps operators off tankers, reducing fall hazards.

2. Flexible Hose Design

The hose bends and stretches, adapting to tanker angles and movements.

3. Secure API Coupler Connection

API couplers snap onto tanker valves with a tight, leak-proof seal.

4. Vapor Recovery Ready

Easily pairs with systems to capture fumes, keeping the air clean.

5. Quick Setup

The hose and coupler combo speeds up connections, saving time. It’s like plugging in a charger—fast and fuss-free.

Bottom Hose Loading Arm, with API Coupler and Break-away Couplings

Specifications of Bottom Hose Loading Arms:

1. Size:

• Liquid hose: 4” (DN100)

• Vapor hoses: 3”/4” (DN80/DN100)

2. Design Pressure:

1.0 MPa (10bar), considering the pressure of API Couplers.

3. Temperature Range:

40°C to +150°C (-40°F to +302°F), covering cold storage to warm chemicals.

4. Hose Length:

6 to 20 feet, adjustable based on tanker height and reach needs.

5. Flange Connection:

4” TTMA (Tank Truck Manufacturers Association) flange, standard for mounting to the arm.

Materials of Bottom Hose Loading Arms:

1. Arm Body

• Carbon Steel: The sturdy backbone, coated or painted for corrosion resistance.

• Stainless Steel (SS304/SS316L):Used for corrosive applications.

2. Hose

• Synthetic Rubber or PTFE: The hose’s core, resistant to chemicals and pressure.

• Reinforced Layers: Braided steel or fabric adds strength.

3. API Coupler Body

• Aluminum (Anodized): Lightweight yet tough, with a hard coat to fight corrosion.

• Stainless Steel: Used for latches and internal parts, resisting rust.

4. Seals

Viton or Buna-N: Seals that handle heat, pressure, and chemicals, ensuring no leaks.

5. Flange Connection

Carbon Steel or Stainless Steel: The flange base, coated for durability.

Flange Connection of Bottom Hose Loading Arms:

The 4” TTMA flange connection is the backbone of the bottom hose loading arm, mounting it to the loading rack or arm. Made from carbon steel or stainless steel, it’s designed to handle high pressure and ensure a leak-proof seal with the tanker valve. Some models add gaskets or seals for extra tightness, making it a universal standard across industries.

Applications of Bottom Hose Loading Arms:

1. Petrochemical Depots

Loading gasoline or diesel. The hose’s flexibility handles misaligned tankers.

2. Chemical Plants

Transferring corrosive chemicals. The API couplers and seals keep it safe and leak-free.

Accessories of Bottom Hose Loading Arms:

• API Couplers: Secure, dry-break connections.

• Vapor Recovery Hoses: Capture fumes, keeping air clean.

• Break-away Couplings: Disconnect safely during pull-aways, preventing spills.

Operation of Bottom Hose Loading Arms:

1. Alignment:

Position the hose end with the tanker’s bottom valve, using its flexibility to adjust.

2. Connection:

Snap the API coupler onto the valve—quick, secure, and leak-proof.

3. Loading:

Open the valve to start the flow, filling compartments as needed.

4. Monitoring:

Check pressure and level with gauges, tweaking if necessary.

5. Disconnect:

Close the valve, release the coupler, and retract the hose.

Why Choose Bottom Hose Loading Arms?

Why not stick with rigid arms? Rigid systems lack flexibility and safety, while bottom hose loading arms offer a bendable, safer option. They’re like the stretchy, smart upgrade to a stiff old tool.

Here are their advantages:

1. Safety:

Ground-level work cuts fall risks, protecting operators and reducing accidents.

2. Flexibility:

The hose adapts to any tanker, saving time.

3. Efficiency:

Fast connections boost throughput and speed up work

4. Durability:

Tough materials handle harsh conditions, reducing costs.

Cautions and Considerations for Bottom Hose Loading Arms:

1. Hose Wear:

Frequent bending can wear the hose—regular checks are key.

2. Coupler Alignment:

Misalignment can leak.

3. Cost:

Higher initial investment pays off with longevity.

Routine maintenance and proper use keep them in top shape.
