Controlled-Dissolution Magnesium Alloy Square Bar

Controlled-Dissolution Magnesium Alloy Square Bar

Engineered Dissolution for Downhole Excellence

Shaanxi Hagrien's Controlled-Dissolution Magnesium Alloy Square Bar is a high-performance structural material designed for oil and gas completion tools. It delivers tensile strength ranging from 300 MPa to 550 MPa while maintaining a low density of approximately 1.8 g/cm³. Our square bars feature tunable dissolution rates from 1 mg/cm²/h to over 100 mg/cm²/h, calibrated to your specific downhole conditions. With extruded profiles available up to Ø300 mm and strict dimensional tolerances per ASTM B107/B107M, you get consistent mechanical performance and predictable degradation timing in temperatures up to 150°C.

What Makes Our Square Bar Different?

Exactness Building for Genuine Wellbore Conditions

You require materials that perform beneath weight. Our square bars are defined based on genuine working parameters—temperature, saltiness, and liquid chemistry. This approach guarantees your components keep up basic astuteness amid operation, at that point break down totally on schedule.

Manufacturing Fabulousness You Can Trust

We control each step from amalgam dissolving to last machining. Our closed-loop framework incorporates CNAS-accredited HTHP research facility approval. This implies you get square bars with uniform microstructure and dimensional solidness. No shocks amid machining. Lower scrap rates for your generation line.

Large-Format Capability with Consistency

Working with huge components? Our expulsion capacity handles profiles up to 300 mm breadth. We keep up strict prepare teach to guarantee each bar—whether 20 mm or 200 mm—delivers the same solid execution. Your machining groups will appreciate the consistency.

Technical Specifications

Where Square Bars Solve Real Problems

Oil & Gas Completion Tools

You're fabricating dissolvable frac plugs, bridge plugs, or setting slips. The square bar geometry disentangles machining of anti-rotational highlights and inside mandrels. Your components withstand extraordinary downhole weights amid operation, at that point disappear in wellbore fluids—no processing required. This disposes of expensive intercession and diminishes non-productive time.

Structural Components for High-Pressure Applications

When you require transitory basic bolster that won't meddled afterward, our square bars provide. The profile gives soundness amid establishment and benefit life. Once the work is done, controlled disintegration expels the equipment without mechanical intervention.

Custom Downhole Tools

Working on a specialized device plan? We bolster engineering-to-spec ventures. Our group makes a difference you select the right amalgam review for your temperature and liquid conditions. We can create from your drawings and bolster model improvement through to scaled generation.

​​​​​​​Why Material Selection Matters?

Tunable Dissolution Kinetics

Not all wells are the same. You might need rapid dissolution in hot, high-salinity brines or slower degradation in cooler formations. Our alloy systems can be calibrated to your specific requirements. We use precision micro-alloying and heat treatment protocols to ensure predictable, uniform dissolution—no premature failure, no unpredictable fragmentation.

Mechanical Integrity When You Need It

The Controlled-Dissolution Magnesium Alloy Square Bar maintains high specific strength throughout its service life. Your tools stay functional under load, resisting mechanical stress and pressure differentials. Dissolution only begins when you want it to, triggered by the wellbore environment you've defined.

Environmentally Responsible

The primary dissolution byproduct is Magnesium Hydroxide—environmentally benign and non-toxic. You meet operational goals without creating long-term environmental concerns. It's effective performance with responsible chemistry.

Frequently Asked Questions

Q: How does temperature influence disintegration of the square bar?

A: Disintegration takes after the Arrhenius equation—roughly talking, rate increments essentially with each 10°C rise. We offer custom amalgam grades optimized for wellbore temperatures from 25°C to 150°C, so you get unsurprising execution at your working conditions.

Q: Can I store these bars in standard stockroom conditions?

A: The bars highlight defensive surface passivation for dealing with. For long-term capacity, we prescribe humidity-controlled situations underneath 30% RH or vacuum fixing to avoid air oxidation.

Q: What weight can components machined from this fabric withstand?

A: Depending on your chosen amalgam review and divider thickness, components can hold differential weights surpassing 70 MPa (10,000 psi) some time recently arranged disintegration begins.

Q: How do you guarantee uniform disintegration instep of fragmentation?

A: We utilize high-ratio expulsion and controlled warm treatment to accomplish fine, homogeneous microstructure. This avoids intergranular erosion that might cause untimely breaking or uneven dissolution.

Q: Are the disintegration byproducts safe?

A: Yes. The essential byproduct is Magnesium Hydroxide, which is non-toxic and naturally benign—often utilized in natural remediation applications.

Q: Can you create from our specialized drawings?

A: Completely. We bolster drawing-based generation, model advancement, and scaling to full generation. Our building group works with you on fabric determination and handle optimization.
