2. Key Features

Innovative Bandlock Mechanism

• Rapid Access Capability:

The Bandlock mechanism is the cornerstone of this closure system, allowing for swift and secure locking and unlocking. This feature significantly reduces the time required for operators to access the pipeline, enhancing operational efficiency and reducing downtime.

Enhanced Sealing Technology

• Pressure-Enhanced Seal:

The EMT Bandlock Closure incorporates a sophisticated sealing system designed to improve under pressure. The seal’s performance enhances as internal pressure increases, ensuring a high-integrity seal that prevents leaks and maintains the pipeline’s safety and environmental compliance.

Safety Features

• Mechanical Locking System:

Safety is paramount, and the EMT Bandlock Closure includes a mechanical locking system that prevents the opening of the closure under pressurized conditions. This crucial feature ensures that the closure can only be opened after achieving a fully depressurized state, safeguarding operational staff and the environment.

Robust and Durable Construction

• Corrosion-Resistant Materials:

Constructed from high-strength, low-alloy carbon steel and enhanced with corrosion-resistant coatings, the closure withstands the harsh conditions of pipeline operations. Its durability is further ensured by resistance to physical and chemical stresses. Particularly in environments containing corrosive agents such as hydrogen sulfide.

Compliance with Global Standards

• ASME and Industry Compliance:

The closure is designed in accordance with ASME Ⅷ Div.1 standards and adheres to specific industry regulations for pressure vessels, ensuring its reliability and safety in global markets.

Customization Options

• Tailored to Operational Needs:

The EMT bandlock quick opening closure can also be customized in terms of material and size to match specific operational requirements, ensuring optimal performance and compatibility with existing pipeline infrastructure.

3. Applications

Oil and Natural Gas Pipelines

• Gathering Systems:

These closures are ideal for installation at key junctions in pipeline gathering systems where multiple source lines converge into a common manifold.

• Transmission Pipelines:

For long-distance transmission pipelines, these closures allow for rapid access during maintenance and emergency operations, minimizing downtime and ensuring operational continuity.

• Maintenance and Inspection:

Regular maintenance and inspection schedules benefit significantly from quick opening closures as they reduce the time and labor required to access pipeline interiors.
