The role of high temperature resistant UPE steel wire hose in high temperature dust transportation i
In the production links of steel smelting, sintering, slag treatment, etc., the transportation of high-temperature dust (such as metal particles, slag powder, iron oxide powder, etc.) puts forward strict requirements on the pipeline system - it must withstand continuous high temperature, resist the erosion of high-wear materials, and have excellent pressure resistance and anti-aging performance. Traditional rubber hoses are prone to hardening and cracking under long-term high-temperature environments, while pure metal pipes have problems such as heavy weight, poor flexibility, and easy corrosion. In response to this challenge, the high-temperature resistant UPE steel wire hose developed by Litong Technology has become an ideal choice for high-temperature dust transportation in the steel industry with its unique material combination and structural design.
Core advantage analysis: Why is UPE steel wire hose suitable for steel mills?
1. Excellent high temperature resistance and adaptability to harsh working conditions
The ambient temperature of dust transportation in steel mills is usually as high as 80~100℃, and some working conditions (such as hot air dust removal and steam blowing) even reach 135℃ for a short time. Litong UPE steel wire hose adopts:
Inner layer of ultra-high molecular weight polyethylene (UPE): temperature resistance range of 30℃~100℃ (long-term), can withstand 135℃ steam sterilization for a short time, and avoid high temperature softening or deformation.
Outer layer of ozone-resistant EPDM rubber: has excellent heat-oxidation aging resistance, and remains flexible after long-term exposure to high temperature air to prevent cracking.
2. Super wear-resistant, resisting metal particle erosion
Steel plant dust usually contains sharp and hard materials such as iron filings, slag, and sintered particles. Ordinary rubber hoses are easily worn out quickly. Litong UPE hose adopts:
UPE inner lining: extremely low friction coefficient, wear resistance is more than 50% higher than ordinary rubber, greatly extending service life.
Multi-layer high-tension steel wire reinforcement: compressive strength reaches 20Bar, preventing pipe bursting during high-pressure transmission, while enhancing negative pressure resistance to avoid suction and deformation.
3. Anti-ultraviolet & high-recognition design to improve safety
The steel plant environment is complex, and the pipeline needs to be weather-resistant and easy to identify:
Red/yellow outer layer glue: High-visibility color design makes it easy for workers to quickly identify the purpose of the pipeline and reduce the risk of misoperation.
UV-resistant EPDM glue layer: Anti-ozone and UV aging when used outdoors, avoiding long-term exposure to cause surface powdering and cracking.
Typical application scenarios
1. Blast furnace dust removal system: convey high-temperature flue ash and sintering dust, and withstand 100℃ continuous hot air.
2. Slag micro-powder transportation: resist high wear of slag particles and avoid frequent replacement of pipelines.
3. Dust recovery in hot rolling workshop: work stably in high temperature and high humidity environment, and use with dust removal equipment.
4. Steam purge pipeline: short-term tolerance of 135℃ steam, suitable for equipment cleaning and maintenance.
Industry Trend: UPE hose gradually replaces traditional solutions
At present, steel enterprises are gradually eliminating ordinary rubber hoses, PVC hoses and even some metal pipes for the following reasons:
Rubber hoses: easy to age at high temperatures, insufficient wear resistance, and short life.
PVC pipes: poor temperature resistance (usually ≤60℃), easy to become brittle.
Metal pipes: heavy, complex to install, and not corrosion-resistant.
Litong UPE steel wire hoses have become an upgraded option for dust transportation in steel plants with their advantages of high temperature resistance, wear resistance, lightweight, and flexible installation, which can help enterprises reduce maintenance costs and improve system reliability.
High-performance hoses help the steel industry to produce efficiently
Under high temperature, high wear, and high corrosion conditions in steel production, Litong high-temperature resistant UPE steel wire hoses provide a safer, more durable, and more economical transportation solution. In the future, as the steel industry's demand for energy saving and consumption reduction and intelligent operation and maintenance increases, the application of such high-performance hoses will be further expanded, driving the industry to develop in a more efficient and sustainable direction.
