In the modern construction era, ensuring clean air quality for civil and industrial buildings is a top priority. One of the indispensable “helpers” in the HVAC (Heating, Ventilation, and Air Conditioning) system is silver ventilation pipeThis product not only facilitates airflow but also offers maximum flexibility during construction.
So silver ventilation pipe What is it? Why is it considered the soft "blood vessels" of construction works? And where is the most reputable supplier in Hai Phong as well as nationwide? Let's Sao Viet Air Duct Explore the details in the in-depth article below.
1. Overview of silver ventilation ducts
1.1. What is a ventilation duct?
Silver ventilation duct, also known as Flexible Duct, is a type of air duct made of many layers of aluminum attached to reinforcing steel wire. The most easily recognizable feature is the shiny silver outer shell, with a flexible folding structure like an accordion, allowing the duct to be easily stretched or contracted.
Unlike other types of rigid ducts (square or spiral round) made from fixed galvanized steel, silver ventilation pipe has the ability to bend and wavy to enter nooks and crannies, narrow spaces that rigid pipes cannot reach. Therefore, this is an indispensable material to connect the main air duct system and air vents, air outlets or connect directly to the exhaust fan equipment.
1.2. Detailed structure
To ensure durability and resistance to wind pressure, a product silver ventilation pipe High-quality products typically consist of three main components:
-
Aluminum foil layer: Layered (usually 2-3 layers) to create absolute airtightness. This silver layer reflects heat, prevents fire spread and prevents gas leaks.
-
Steel Wire Frame: Is the “backbone” of the tube. The high-strength spring steel wire (carbon steel) runs spirally along the length of the tube, helping the tube maintain a round shape, not be deformed when bent and withstand the suction/push pressure of the fan.
-
Adhesive layer: Use special heat-resistant glue to tightly bond the aluminum film and steel frame, ensuring the pipe will not peel off during operation at high temperature.
2. Classification of common silver ventilation pipes on the market
Based on insulation needs and construction characteristics, silver ventilation pipe divided into two main types:
2.1. Non-insulated Flexible Duct
This is the basic type of tube, consisting only of an aluminum foil layer and steel wire.
-
Characteristic: Lightweight, inexpensive, and extremely flexible.
-
Application: Often used for conventional ventilation systems, family kitchen exhaust, toilet exhaust or places that do not require strict insulation or soundproofing.
2.2. Insulated Flexible Duct
This type is an upgraded version of silver ventilation pipe Typically, it is wrapped in a layer of glass wool or polyester fiber in the middle, and then covered with another layer of silver foil on the outside.
-
Characteristic: Excellent heat insulation and heat retention, reduces noise caused by air circulation. Prevents water condensation outside the pipe when conducting cold air.
-
Application: Specialized for central air conditioning systems, cold air ducts, projects requiring high fireproof and soundproofing standards such as cinemas, auditoriums, hospitals.
