Product Description:

1.  Aluminum Foil Ducts Description

The production technologies and products performance of aluminum foil facing have been up to international advanced level. The aluminum foil facing products are mainly used for HVAC system, refrigerators, building thermal aluminum foil facing insulation and laminated with glass wool and rock wool to increase the insulation function.

• FSK aluminum foil facing is mainly used for duct wrap in HVAC system and other fields, such as vapor barrier etc., and suitable for off-line lamination of glass wool or rock wool. By special processing, the facing will have excellent flame retardant property.

• Heat-sealing aluminum foil facing is used for duct wrap without applying extra adhesive and suitable for online lamination of glass wool and rock wool.

2.Main Features of the Aluminum foil Ducts

• Light weight

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

5.FAQ

We have organized several common questions for our clientsmay help you sincerely

(1)What is the storage condition?

The products should be stored at room temperature and kept from wet and heat source.

It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied must be clean, dry, and free of grease and oil.

The user should take test and do trial-application on the above products before coming into application so as to witness and ensure suitability for user’s special purpose and technique. 

(2) How to guarantee the quality of the products?

 We have established the international advanced quality management system,every link from raw material to final product we have strict quality testWe resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

Q:Safety evaluation: gas pipeline and discharge pipe should not be set between the valve, what is the specification of which provisions?
In the past, the external wall insulation technology prevails, the external wall insulation is in the experimental stage, Basically no
Q:I would like to ask under the gas access point position
The cost of the main cantilever is as low as the secondary structure can be moved
Q:How to optimize the construction management to improve the quality of construction projects
flexible waterproof casing for seismic fortification of the region, rigid waterproof casing for the pipeline to touch the tattoo Du Gu Sen single point of the wall does not bear the vibration of the building
Q:Why should the flexible hose be set in the mechanical ventilation system?
Bowl buckle price is high! There are many buckle-style markets, so rent up cheap!
Q:Is the clamp type flexible connector connected to the pipe to the rubber pad?

Temporary electricity construction program 7. High operating construction program 8. Tower crane construction plan 9. Multi-tower operation anti-collision construction program 10. Emergency emergency plans 11. Winter rainy season construction program 12. Significant hazard assessment measures 13. Construction organization design 14. Building energy conservation program 15. Basket construction program 16. Tower crane hoisting program
Q:The first generation of the tube is that year out?
It is made up of corrugated flexible tube, net cover and joint Metal hose with austenitic stainless steel or according to user requirements of the material manufacturing, metal hose has excellent flexibility, corrosion resistance, high temperature resistance (-235 ℃ ~ +450 ℃), high pressure (up to 32MPa) , Metal hose in the pipeline can be connected in any direction for temperature compensation and absorption of vibration, reduce noise, change the direction of media transmission, to eliminate the pipeline or between the pipe and the mechanical displacement between equipment, double flange metal corrugated hose It is particularly suitable for flexible joints with various pumps, valves and so on for displacement and vibration Metal hoses use two kinds of bellows, one is a spiral corrugated tube; the other is a ring bellows Solution: Songjiang metal hose
Q:Heating pipe through the deformation of the joints, the album is written on the "metal hose", the problem one: This is a flexible hose? Question 2: how to set the quota
When the construction unit dismantles the top steel formwork, the 18 steel pipes (4m long and 4m each) and the fasteners are transported to the hanging plate of the frame
Q:I am sorry to see your answer in Baidu, can I also pass a copy of my construction and decoration project example?
The lithium battery as long as the choice of a good shell, it does not matter
Q:To ask why the use of clamps connected to the spray pipe after the flush again after the water there will be a lot of hook link position leakage phenomenon? Thank you! The The
The radial force of the seal is far greater than the axial force of the connecting bolts but all the axial force washers 窢 field urging 讵 peculiar aldehyde support, good self-sealing effect by the pipeline through the media rubber ring pressing force pressure more sealing performance of the more pressure to prevent the pressure of the rubber ring to the inner diameter of the tube end of the interface diameter Preload to prevent the media pressure leakage and the blue compared to the higher the pressure of the pipe the more the advantages of the more dangerous the pipe junction at the flexible state of the clamp and the tube between the gap between the clamp clamp a small number of adjacent pipe to allow the corner tube Pipe pipe between the end of the gap to allow the axial shift of the pipeline to adapt to the expansion and contraction of the pipe; pipe interlocking effect reduced 70% mechanical vibration
Q:Maintenance Skills of Leakage of Fire Pipe Clamp Joint
Aluminum alloy small heat dissipation fast! Not conductive! Hope to help you
