Industrial Welding Pad Level Gauge Supplier “IWAKO”

 

Industrial Welding Pad Level Gauge Supplier : The IWAKO Welding Pad Level Gauge is a reinforced-type level indication unit designed for direct welding installation onto pressure vessels and process tanks.

This configuration integrates:

• Weld pad reinforcement plate

• Level gauge body (bolted glass chamber)

• Top and bottom isolation valves

• Drain / blowdown valve

The welded pad compensates for shell material removed during vessel penetration.
This maintains structural integrity while providing direct visual level confirmation.

Welding Pad Level Gauge Function

When a vessel wall is cut for nozzle installation, the pressure boundary is weakened.

Cause → Effect:

Wall penetration → Reduced sectional strength → Stress concentration
Weld pad reinforcement → Area replacement → Restored pressure integrity

The level gauge chamber is hydraulically connected to:

• Upper vapor space

• Lower liquid zone

Pressure equalization ensures that the liquid level inside the gauge corresponds exactly to the internal vessel level.

No electronics.
No signal conversion.
Direct mechanical indication.

Welding Pad Level Gauge Structural Configuration

Main Components

1. Reinforcement pad (welded to vessel shell)

2. Nozzle neck connection

3. Gauge body frame

4. Transparent / reflex glass

5. Multi-bolt compression cover

6. Isolation valves (top & bottom)

7. Blowdown valve

The multi-bolt design distributes compressive load uniformly across the glass surface.
Uneven torque application can induce localized stress and reduce glass life.

Welding Pad Level Gauge Technical Characteristics

• Installation Type: Welding pad (direct welded mounting)

• Connection: Flanged valve assembly

• Orientation: Vertical

• Indication Method: Direct visual

• Glass Type: Reflex or transparent

• Body Material: Carbon steel or stainless steel (as specified)

• Pressure Rating: Defined by flange class and vessel design

Final specification must align with vessel pressure class and operating conditions.

Welding Pad Level Gauge Applications

Welding Pad Level Gauges are typically installed on:

• Pressure vessels

• Steam boilers

• Chemical reactors

• Process tanks

• High-temperature systems

• High-pressure service lines.

 

The IWAKO Welding Pad Level Gauge is a reinforced mechanical level indication solution for pressure-boundary applications.

It provides:

• Direct visual confirmation
• Restored shell strength via weld pad
• Isolation capability for maintenance
• Durable industrial construction

This is a structural component integrated into the vessel pressure boundary and must be specified accordingly.
