Everything you need to know about flexible hoses for industrial use

Flexible hoses are essential components in various industrial sectors, being used to transfer liquids and gases, transport abrasive materials and extract dust. Its application ranges from food and pharmaceutical industries to chemical and agricultural sectors.

Selecting the correct model is essential to guarantee its durability, efficiency and the safety of your processes. With a wide variety available, understanding the characteristics and applications of each type of hose is essential to making the right choice. In this article, we will help you understand the main types of hoses, the necessary care and how to choose the most suitable model for your industry.

Why is choosing the right hose important?

Improper hose selection can result in leaks, mechanical failures and high operating costs. Each type of hose is designed to withstand specific conditions such as abrasion, high temperatures, pressure and contact with chemicals. Therefore, understanding your process requirements is the first step to avoiding errors and optimizing your operation.

Main types of industrial hoses

1. Polyurethane (PU) hoses:

• Features: high abrasion resistance, flexibility and long service life. Our models (product link) are reinforced with copper wires.
• Applications: ideal for transporting solid and abrasive materials, such as sand, grains and dust in ceramic, chemical, agricultural and mining industries.

2. PVC hoses:

• Features: Light, versatile and economical, they can be reinforced with steel spirals (product link) to withstand high pressure.
• Applications: transport of liquids, compressed air and less abrasive materials. They are widely used in the food and construction sectors.

3. Rubber hoses:

• Features: thermal, chemical resistance and flexibility.
• Applications: chemical, automotive and oil and gas industries.

4. Silicone hoses:

• Features: resistance to high temperatures and non-toxicity, meeting health standards.
• Applications: food, pharmaceutical and medical industries.

Criteria for choosing the ideal hose

1. Material transported: consider the properties of the material that will be driven. Abrasive, chemical or viscous products require specific materials. Chemically incompatible materials will cause the hose to deteriorate quickly.
2. Temperature of the material to be transported and the environment: Each material has its operating temperature range.
3. Pressure type and level: Discharging fluids is a positive pressure operation and suction is a negative pressure operation. This factor influences the choice of reinforcement. Make sure the hose is able to withstand these factors without compromising safety.
4. Use environment: for adverse environments, such as outdoor areas or areas with high chemical exposure, choose materials with high resistance to wear and corrosion.
5. Frequency of use and flexibility: in processes that require constant changing of hoses, such as chemical industrial trucks, choose light and flexible materials that facilitate handling.
6. Safety standards: ensure that the hose meets applicable regulations, especially in food and pharmaceutical industries.

Tips and care

• Do not underestimate the importance of the correct diameter: an unsuitable hose can cause a loss of efficiency.
• Always consider reinforcements, such as steel spirals, for processes involving high pressure or suction.
• Perform regular inspections to identify wear and replace compromised hoses. Take the opportunity to monitor the durability of the material you are purchasing.
• Keep extra hoses in stock to allow for immediate replacement when necessary.
• To ensure maximum performance and useful life, store hoses in a dry place protected from UV rays and aggressive chemical agents.
