Aluminum Castings For Shale Gas Fracturing Equipment Accessories

1. Extremely lightweight, suitable for high-frequency transition construction of gas wells.

Using high-pressure specialized high-strength aluminum alloy material, while ensuring compressive strength, it reduces weight by 35% -50% compared to traditional steel fittings, significantly reducing the overall weight of the fracturing unit. Shale gas wells are mostly distributed in mountainous and hilly areas, with scattered well sites and frequent transitions. Lightweight cast aluminum fittings can effectively reduce vehicle load, improve equipment road passability, reduce transportation fuel consumption and chassis wear, greatly enhance the flexibility of gas well fracturing construction, and adapt to the fragmented and high-frequency construction mode of shale gas.

2. Anti erosion and fatigue resistance, suitable for high-pressure sand fracturing conditions.

In response to the harsh working conditions of high sand ratio, large displacement, and high-pressure air flow mixed sand flushing in shale gas fracturing, the product is refined and melted, densely cast, and strengthened by heat treatment. There are no pores, sand holes, or loose defects inside the product, and the structure is uniform and dense. It can withstand high-pressure fluid impact, quartz sand abrasion, and high-frequency alternating pressure loads for a long time, effectively preventing problems such as cracking, deformation, leakage, and erosion failure of ordinary castings. Its resistance to high-pressure fatigue performance is greatly improved, and it is suitable for long-term and uninterrupted volume fracturing operations of shale gas, greatly reducing the frequency of equipment shutdown and maintenance.

3. Efficient heat dissipation and stable temperature, avoiding high temperature faults during continuous operation.

Aluminum alloy has excellent thermal conductivity and heat dissipation performance, with a much higher heat dissipation efficiency than steel. It can quickly dissipate the large amount of accumulated heat generated by continuous operation of hydraulic fracturing systems, powertrains, and electrical control boxes, stabilizing hydraulic oil temperature and equipment chamber temperature.
Effectively avoiding hydraulic pressure relief, seal aging, electrical failure, equipment overheating and shutdown caused by high temperature during long-term full load fracturing construction of shale gas, greatly improving the efficiency of gas well fracturing construction.

4. Precision integrated molding, strong sealing, and convenient operation and maintenance.

Adopting integrated precision casting+CNC precision milling processing, the product has high dimensional accuracy, good fitting surface adhesion, excellent sealing performance of fluid pipelines and valve accessories, and completely eliminates the hidden dangers of high-pressure oil and gas and fracturing fluid leakage.
The integrated structure has no welding joints, stronger structural stability, and lightweight design for easy disassembly and assembly, effectively reducing the operation and maintenance costs and labor intensity of daily equipment maintenance and accessory replacement.

The product is suitable for exclusive shale gas extraction scenarios and is widely used in construction projects such as segmented fracturing, volumetric fracturing, repeated fracturing of old wells, and reservoir transformation to increase production in shale gas horizontal wells. It is fully equipped with vehicle mounted high-pressure fracturing units, intelligent sand mixing equipment, high-pressure manifold control systems, and outdoor explosion-proof electrical control systems, and is suitable for large-scale fracturing construction, equipment maintenance and replacement, and equipment lightweight upgrading and transformation in major shale gas fields.
