Specification :

No.1 Introduction:
Galvanized Spiral Gas Drainage Tube is adopted international advanced production equipments by our company. It’s galvanized with the inner and outside. It includes jointing spiral tube and without-jointing spiral tube. 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 Gas Drainage Tube in coal mines.
The jointing spiral tube is adopted cast steel flange connection, the automatic welding technics for the connection of tube body and flange.
Comparing with riveting technics, the technics avoids the second scathe to the tube body, and also with better capability of gasproof.
Due to the techniques of riveting with the misdistribution of joints, and the improper installation is easily leading to rips of tube. 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:
1 . Comparing with the traditional glass steel gas drainage tube and steel gas drainage tube, the mine-use galvanized spiral gas drainage tube has 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 tube 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.
(2) Advantages of Galvanized Spiral Tube 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 tube and rectangle tube.
6. Saving material.
7. Low cost installation.
8. Elegance of integrated overall arrangement.
9. Convenient daily maintenance.
