Ventilation Ducts for Mines

No.1 Introduction

Ventilation Ducts for Mines are adopted international advanced production equipments by our company. It's galvanized of  the inner and outside of the ducts. It includes jointing spiral ducts and without-jointing spiral ducts. It has the following advantages: smooth inner wall, little resistance, light in weight, corrosion-proof, long service life, low cost, etc, it is the ideal equipment of  ventilation duct in mines.

The jointing ventilation duct is adopted cast steel flange connection, the automatic welding technics for the connection of ducts body and flange.

Comparing with riveting technics, which avoids the second scathe to the duct body, and also with better capability of gas-proof.

Due to the techniques of riveting with the misdistribution of joints, and the improper installation is easily leading to rips of duct. Aiming to the point, our company meets track with international technics and adopts integrated welding technics to avoid the existence problems of riveting. 

No.2 Usage

The product can be widely used in mine ventilation, gas drainage, and road and bridge construction, housing structure, discharging lampblack, draining contamination and basic equipment installation, etc.

No.3 Product Advantages

A. Comparing with the traditional glass steel ventilation ducts and steel ventilation ducts, the mine-use galvanized ventilation ducts have the following advantages:
1. Light of the pipeline in weight and easy to convey.
2. High-grade galvanized steel belts used and there is no use to consider of the burning blockage and electrostatic-proof problems.
3. Widely applicable diameter range from 80mm to 1600mm.
4. Spiral hinge mouth increases the loading power and pressure from the pipeline.
5. Inner wall of duct is smooth, little resistance and good circulation.
6. Galvanization prolongs service life.
7. Adopting cast steel flange connection, easily assembly and disassembly, with good interchangeability.

B. Advantages of Galvanized Ventilation Ducts for Air-conditioner
1. Good match with other products and high standardization.
2. Good capability of airproof.
3. Low wastage of aeration.
4. Convenient project checking.
5. Pressure resistance is better than ordinary ducts and rectangle ducts.
6. Saving material.
7. Low cost installation.
8. Elegance of integrated overall arrangement.  
9. Convenient daily maintenance.

Ventilation Ducts for Mines are adopted international advanced production equipments by our company.Light and safe for mines.
