Our nonmetallic  ventilation duct is applied more widely in ventilation ductwork of many fields because of its unique performance and steady quality. It has many features such as large scope of heat-resistant, high pressure resistance, strong anticorrosion, good fire resistance, sound resistance and shock absorption, good flexibility, etc. compared to traditional metallic  corrugate pipe, it avoids rigid force transmission, eliminates the vibration in the pipeline, solves the compensation rate problem of fanner’s expansion and contraction and level shift problem, which is difficult to avoid in metal parts. At mean time, it can protect fan in the accident. In addition to this, it is far superior to metallic  corrugate pipe in the terms of transportation, installation, cost, maintenance, etc. It is the successor of  traditional metallic  corrugate pipe.

One,Main Technology Performance Of Ventilation Duct(Compensator)

Two:Nonmetallic Ventilation Duct (Compensator)  Features

Nonmetallic ventilation duct, which is made of various special nonmetallic material with good physicochemical properties, is a kind of pipeline connection unit. It has features as following:

1,Non rigid force transmission: The nonmetallic ventilation duct is made of flexible material, so it eliminates rigid force transmission, optimize pipeline design, extended the usage life of pipeline equipment.

2,compensation for thermal expansion: pipeline system will cause polydirectional shift along with sharp change of the temperature. Nonmetallic ventilation duct can supply all-round compensation in a smaller space.

3,heat-resistant, flame-resistant, anticorrosion: Nonmetallic ventilation duct is made of nonorganic materials, so it has high performance of  heat-resistant and flame retardant. And you can choose compatible material structure according to working media difference in order to solve corrosion problem.

4,Compensation for installation error : The system errors can’t be avoid in the procedure of  design, manufacturing, installation of the pipeline. However, nonmetallic ventilation duct can effectively get rid of those errors.

5,Excellent tightness: The tightness of nonmetallic ventilation duct is very good, it can offer good sealing in the surround of any media.

6,Sound resistance and shock absorption: All of the main material and structures of the nonmetallic ventilation duct  have function of sound resistance and shock absorption. It can effectively reduce the noises and vibration caused by boiler fan system, etc.

7,Short period of production: The production period of this product is very short, can satisfy customer’s special demand of delivery time.

8,Convenient installation and transportation: The main body of nonmetallic ventilation duct adopts nonmetallic materials, so it makes installation and transportation easy.

9,Good cost performance: The price of nonmetallic ventilation duct is much less than that of metallic corrugate pipe.

10,High flexural strength and tensile strength:   Flexural strength>9000times, tensile strength>1900N/5cm

11,Super weather fastness: The quality and strength almost remain in the condition of wind and rain.

12,resistance to strong acid, strong alkali, aqua fortis, Organic solvent, etc.

13,Working temperature: -100℃~1200℃(can be ordered accordingly)

Three,Connecting Format

The usual two kinds of connecting format for nonmetallic ventilation duct  (compensator) is flange form and astragal form. Customer must offer the flange size or pipeline outlet diameter size, axial length, displacement or component drawing.

1.Flange connection: Flange connection is configuration of traditional expansion joint, it has flanging. The diameter can be made over 6m, and can be also made into all kinds of adjustable type, flexible type, corrugatedpipe type, etc. During installing, the ventilation duct flange should match the pipeline flange.

2.Astragal platen form: Astragal form connection is cylinder connection, it has no flanging.  During installing, plug butt joint, fasten by matched clamp. The sheet of compensation dosage between the installation length & effective length of astragal axial and ventilation duct.
