Do Low-cost Blowing Pipes Really Save Money?

Written by Author Name | 2025.03.14

In the heavy industry, cost-saving strategies are essential for maintaining profitability. However, many factories are unknowingly increasing expenses by using low-cost flux blowing pipes that do not meet corrosion and heat resistance requirements. These alternatives may seem like a budget-friendly choice, but do they actually save money? Let's take a closer look at the real cost of using those blowing pipes.

Consequences of Using Low-cost Blowing Pipes in Aluminum Melting

"Low cost" refers to standard pipes made from mild steel pipes, which may or may not have a strong corrosion-resistant coating on the steel pipe surface. In terms of function, this type of pipe operates normally to blow flux into the aluminum melting furnace. However, in terms of features, it has a high susceptibility to corrosion and poor heat resistance. When using those low-cost pipes for flux injection, its surface deteriorates quickly, and the following problems arise:

Frequent Replacements Increase Costs: Regular replacement of worn-out pipes adds up financially.
Production Disruptions: Each replacement requires downtime, reducing overall operational efficiency.
Potential Product Contamination: low-cost black pipes may introduce unwanted impurities into the molten aluminum, affecting final product quality.

Why Do Low-cost Blowing Pipes Deteriorate Quickly in Aluminum Furnaces?

Despite aluminum’s relatively low melting point (~600°C), the highly corrosive nature of molten aluminum leads to rapid material degradation. Several key factors contribute to the quick deterioration of low-cost blowing pipes:

Corrosion – Molten aluminum reacts with oxygen and metals, corroding low-cost pipes.
Oxidation – Exposure to air weakens the pipes over time.
Impurities – Alloy elements (Mg, Si, Fe) speed up corrosion.
Erosion – Molten metal flow gradually wears down the pipes.
Thermal Stress – Heating and cooling cycles cause cracks and faster wear.

Low-cost Blowing Pipes May Be Costing You More in the Long Run

Many people believe that opting for less expensive flux blowing pipes leads to greater savings. However, the actual cost comparison tells a different story.

And this is how low-cost blowing pipes may be costing you more in the long run.

Hidden Costs – More material expenses, labor, and downtime.
Indurability Costs More – Low-cost pipes lead to higher expenses over time.
Smarter Choice – Invest in long-lasting pipes for better efficiency.

Solution: Choose High-Durability Corrosion-Resistant Blowing Pipes

To truly cut costs without compromising performance, businesses should invest in corrosion-resistant and heat-resistant flux blowing pipes. These purposefully designed blowing pipes are engineered to withstand the extreme conditions inside aluminum furnaces, offering:

Corrosion & heat resistant – Prevents degradation from molten aluminum, oxidation, and high temperatures.
Longer lifespan – Lasts much longer than conventional carbon flux blowing pipes.
Highly durable – Resists thermal stress, cracking, and erosion.
Cost-efficient – Reduces maintenance costs and downtime.

Daiwa CA Lance: Offering Both Corrosion and Heat Resistance for Aluminum Melting

To meet the demand for extended product lifespan and cost optimization, Daiwa CA Lance was developed with the following outstanding features:

Corrosion-Resistant & Heat-Resistant Features

Calorized Layer (Aluminum Ferro Alloy → Alumina Oxide (Al₂O₃)): The calorized layer is the protective coating of Daiwa CA Lance, created through the diffusion of aluminum ferro alloy into the pipe. At high temperatures, the aluminum ferro alloy reacts and transforms into alumina oxide (Al₂O₃), forming a highly durable protective barrier. This corrosion-resistant layer prevents molten aluminum from penetrating the base metal, shielding it from oxidation and chemical degradation.
Refractory Ceramic Coating: This is a heat-resistant ceramic layer adds extra protection, reducing heat-induced wear and ensuring structural stability under extreme temperatures.

Thanks to the reinforcement of these two protective layers, the surface coating of the CA pipe is strengthened by 3x to 7x compared to conventional low-cost blowing pipes, significantly enhancing durability and performance in harsh furnace conditions.
