Key features of a concrete delivery hose rubber tube

A concrete delivery hose rubber tube, also known as a concrete pump hose or simply pump hose, is a specialized hose used in construction projects, particularly in concrete pumping applications. It is an essential component of a concrete pump, which is a machine used to transfer liquid concrete (concrete slurry) from a mixer to the desired location on a construction site.

The concrete delivery hose is designed to withstand the high pressure and abrasive nature of the pumped concrete. It is typically made of high-quality rubber or a combination of rubber and other materials to provide flexibility, durability, and resistance to abrasion. The inner tube of the hose is smooth to allow the concrete to flow with minimum resistance.

Key features of a concrete delivery hose rubber tube:

1. Size and Length: The hoses come in various sizes, typically ranging from 2 inches to 6 inches in diameter, depending on the concrete pump's capacity. The length of the hose can also vary, commonly ranging from 10 meters to 20 meters (30 feet to 65 feet) or more.

2. Reinforcement: To handle the high pressure involved in pumping concrete, the hose is reinforced with layers of high-strength materials, such as synthetic fibers or steel wire braids.

3. End Fittings: The ends of the hose are usually equipped with couplings or fittings that connect to the concrete pump and the nozzle or hose attachment used at the discharge end.

4. Abrasion Resistance: The outer cover of the hose is designed to be resistant to abrasion and damage, especially when dragged over rough surfaces or sharp edges on the construction site.

5. Flexibility: The hose needs to be flexible to allow for easy maneuvering and positioning during concrete placement.

6. Pressure Rating: Concrete delivery hoses are rated for specific pressure levels, and it is crucial to use hoses that can handle the pressure generated by the concrete pump.

Using a proper and well-maintained concrete delivery hose is crucial for the safe and efficient pumping of concrete. The hose should be regularly inspected for signs of wear, damage, or leakage. Any damaged hose should be replaced promptly to prevent accidents and ensure smooth concrete placement during construction projects. Additionally, the concrete pump operator must follow safety guidelines and recommended practices to avoid hose-related issues and potential hazards on the job site.
