What Makes Our Magnesium Alloy Round Bar Essential for Your Operations

Engineered for Multi-Stage Fracturing

You face complex challenges in horizontal well completions. Our Magnesium Alloy Round Bar for Dissolvable Plug Body Components solves your most pressing operational concerns. This high-performance degradable material serves as the primary structural component for bridge plugs and frac plugs.

Unlike traditional cast iron or composite materials, our magnesium alloy provides full metal strength while completely dissolving in wellbore fluids after your fracturing operation. You eliminate costly drill-out phases. You reduce non-productive time. You accelerate your transition to production.

Real Performance You Can Measure

Your operations demand materials that work under extreme conditions. Our round bars deliver:

• Mechanical integrity: Yield strength exceeding 250 MPa supports differential pressures up to 10,000-15,000 psi
• Lightweight advantage: Density of approximately 1.8 g/cm³—75% lighter than steel—simplifies deployment in long lateral wells
• Controlled degradation: Customizable dissolution rates match your specific temperature (25°C to 150°C) and chloride concentration requirements
• Zero internal defects: 100% ultrasonic testing ensures structural reliability

Application-Specific Engineering

We design our alloy systems based on your actual operating conditions. You benefit from materials optimized for:

Horizontal Well Multi-Stage Fracturing

Your plugs isolate zones during high-pressure pumping. Once the job completes, the material dissolves completely. You get a full-bore production path without intervention.

High-Temperature Deep Well Environments

In HTHP conditions where mechanical retrieval tools often fail, our dissolvable bars provide fail-safe isolation. The material removes itself regardless of depth or access limitations.

Offshore and Subsea Operations

Where your rig rates exceed hundreds of thousands per day, you eliminate coiled tubing mill-out operations. You save significant logistical and operational expenses.

Temporary Zonal Isolation

Your completion design requires precise pressure control across multiple zones. Our round bars machine into components that maintain structural integrity exactly when you need it, then dissolve on your schedule.

Technical Specifications

Manufacturing Excellence That Reduces Your Risk

Integrated Production Control

You need suppliers who control quality at every step. Our closed-loop manufacturing system gives you that assurance:

Alloy Formulation

We design magnesium alloy compositions based on your specific well parameters. Temperature, salinity, and required dissolution timeline all factor into our material selection.

Extrusion Process

Our controlled extrusion parameters create uniform microstructure throughout the round bar. You get dimensional stability and high surface quality that reduces your machining scrap rates.

Verification Testing

Our CNAS-accredited HTHP laboratory simulates your actual wellbore conditions. We verify dissolution rates in your specific fluid chemistry before production scaling.

Batch Traceability

Every Magnesium Alloy Round Bar for Dissolvable Plug Body Components comes with complete documentation. You receive chemical composition analysis via Optical Emission Spectroscopy, ultrasonic flaw detection reports, and mechanical testing data.

Quality Assurance You Can Audit

Your supply chain demands transparency. We provide:

• Chemical composition analysis: OES testing ensures precise alloying percentages

Frequently Asked Questions

Q: How do you control the dissolution rate of your magnesium alloy round bars?

A: We use precision micro-alloying and controlled heat treatment processes. These create specific galvanic cells within the metal matrix. You can customize the dissolution rate based on your well's salinity and temperature profile. Our laboratory tests verify the degradation curve in fluids matching your wellbore conditions before production.

Q: Can your round bars withstand 15,000 psi differential pressure?

A: Yes. Our high-strength grades maintain structural integrity under ultra-high-pressure conditions throughout the fracturing stage. We engineer the alloy composition and heat treatment specifically to meet your pressure requirements while preserving controlled dissolution characteristics.

Q: What happens if my wellbore fluid has low salinity?

A: We provide specialized "active" alloy grades containing specific catalysts. These ensure complete dissolution even in fresh water or low-chloride fluid environments. The dissolution mechanism doesn't rely solely on chloride content, so you get reliable performance across diverse fluid chemistries.

Q: How should I store the material to prevent premature degradation?

A: Store round bars in a dry, temperature-controlled environment. We recommend protective packaging that limits moisture exposure. Proper storage maintains material properties until you're ready for machining. We provide specific storage guidelines with each shipment based on the alloy grade.

Q: Do you support custom diameter requirements?

A: Absolutely. Our extrusion capability extends to Ø300 mm, and we regularly produce custom diameters for specific plug designs. Share your technical drawings with us. We'll confirm feasibility and provide lead times for your custom specifications.

Q: What documentation do you provide for supplier qualification?

A: Each batch includes Certificate of Analysis (COA), Certificate of Conformance (COC), and Safety Data Sheet (SDS). You also receive ultrasonic inspection reports, mechanical test data, and dissolution rate verification results. Our documentation packages support your audit and compliance requirements.

Q: Can you expedite delivery for urgent projects?

A: Yes. We maintain safety stock for standard sizes and can prioritize production for critical timelines. Contact us with your project schedule. We'll work with you to meet your completion deadlines while maintaining our quality standards.

Q: How do your round bars compare to other dissolvable materials?

A: Our magnesium alloy provides superior mechanical strength compared to polymer-based dissolvables. You get full-metal structural performance with controlled degradation. The material machines like conventional metals, simplifying your manufacturing process while delivering the dissolvable functionality you need.
