Frequently Asked Questions

Welcome to our Industrial Hose FAQ section. Here you’ll find answers to common questions about slurry discharge hoses, suction hoses, and heavy-duty rubber hoses for mining and dredging. If you need more information, feel free to contact our technical support team for expert guidance.

What is a slurry discharge hose, and what is it used for?

A slurry discharge hose is a reinforced rubber hose built to transfer thick, abrasive slurries that contain water, sand, and minerals. It is primarily used in mining, dredging, and construction to move large volumes of abrasive material safely and efficiently.

What makes a slurry discharge hose different from a standard industrial hose?

Unlike general-purpose hoses, slurry discharge hoses are engineered with thick abrasion-resistant liners, strong synthetic reinforcements, and flexible bodies to withstand severe wear and high pressure. This design ensures durability and consistent performance in tough field environments.

How does a slurry discharge hose resist abrasion?

The hose’s inner lining is made of premium rubber compounds designed to handle continuous friction from sand, gravel, and mineral particles. This construction minimizes wear and extends service life compared to regular rubber hoses.

How do I select the correct size of slurry discharge hose?

To select the right hose size, consider the slurry density, flow rate, and system pressure. For most medium-duty mining or dredging setups, a 4-inch slurry discharge hose provides optimal balance between flow capacity and handling flexibility.

What industries commonly use slurry discharge hoses?

These hoses are widely used in mining, sand dredging, construction dewatering, and industrial waste transport — any operation that requires the safe movement of abrasive or high-density fluids.

What is an industrial suction hose, and how is it different from a discharge hose?

An industrial suction hose is designed to draw fluids or mixtures into a system, while discharge hoses push materials out. Suction hoses typically include wire or textile reinforcements to prevent collapse under negative pressure, ensuring stable flow during operation.

Why is vacuum resistance important for suction hoses?

Vacuum resistance keeps the hose from caving in when negative pressure builds up during suction. This feature is essential in deep mining or long-distance pumping where suction strength is high.

What maintenance helps extend hose lifespan?

Inspect hoses regularly for surface cracks, soft spots, or deformation. Store them flat in a cool, dry area away from direct sunlight and chemicals. Using the correct couplings and avoiding excessive bending can significantly extend service life.

Can a 4-inch slurry discharge hose handle high-temperature materials?

Yes. Certain 4-inch slurry hoses can be customized with heat-resistant inner linings that withstand temperatures up to 80°C (176°F), making them suitable for hot slurry, ash, or industrial byproduct applications.

What safety measures should be followed when using slurry hoses?

Always ensure proper grounding when handling flammable or conductive materials. Secure all fittings before operation and avoid exceeding the rated pressure. For high-abrasion or high-temperature applications, consult our engineers for guidance on the most suitable hose construction.
