In recent years, the use of stainless steel duct has become more and more common, especially in the kitchen exhaust system. Kitchen grease exhaust system ducts are mostly required to use the thickness of 1.0mm and above the production of stainless steel plate, but the kitchen grease exhaust system for the thin plate rectangular duct connection, usually used in the past in the form of flange connection, ducts using welded molding is rare.
Stainless steel duct, stainless steel welded duct can be divided into round and rectangular. According to the different requirements of the project site, we can produce finished ducts of various shapes, various specifications and plates. The main materials of stainless steel duct are: SUS304, 316, 303, 310, 310S, 301, 302, 304L, 316L, 321, 201, 202, 902, 904, 317, 430 and so on. The surface properties of stainless steel ducts mainly include 8K mirror plate, colored stainless steel plate, stainless steel frosted plate, stainless steel brushed plate, stainless steel pattern plate, stainless steel etching plate, titanium, snowflake sand, 2B plate, BA plate and industrial medium-thickness plate.
Because of its excellent corrosion resistance, heat resistance, high strength and other physical and chemical properties, finished stainless steel duct is mainly used in a variety of airtightness requirements of the process exhaust system, solvent exhaust system, organic exhaust system, exhaust gas exhaust system and the outdoor part of the general exhaust system, hot and humid exhaust system, smoke exhaust system and dust removal system.
Stainless steel welded duct features.
1, beautiful appearance, smooth inner wall, low resistance, good airtightness, high compressive strength, can be suitable for very complex exhaust project.
2、It can exclude combustible and non-combustible chemical corrosive gases, and does not need to install sprinkler fire extinguishing equipment.
3、Made of stainless steel, strong material, easy to maintain integrity.
4, Stainless steel duct ECTFE Coating internal coating, with a high degree of resistance to chemical acids and alkalis, impact resistance, corrosion resistance and high temperature, which can be applied to temperatures between 150℉~300℉ (-66℃~149℃).
5、Using computer-aided design, easy to install. It can be used in the environment without fire extinguishing device, which can save the cost of installing fire extinguishing device.
6、It is more expensive than galvanized duct, easy to transport and adapt to site changes.
Stainless steel air ducts are used in:
Clean rooms, semiconductor industry, printed circuit board industry, petrochemical industry, pharmaceutical dispensing industry, pulp and paper industry, food processing industry, including laboratories for flammable, volatile, corrosive chemicals, any industry or facility regarding corrosive, flammable exhaust delivery and output.
Ventilation ducts are mainly used in those places?
Ventilation ducts are mainly used in industrial and construction projects, the application areas mainly involve: electronic industry dust-free plant purification system, medical food aseptic workshop purification system, hotel and guesthouse, shopping malls and hospitals, factories and office buildings in the air-conditioning system, industrial pollution control with the dust, smoke, oil, and other exhaust ducts, the industrial environment or the post with the comfort of the supply ducts, the coal mine with the gas extraction gas pumping system, the environment of the coal mine Control with the air supply and return system… etc.
Stainless steel angle iron flange duct
Stainless steel angle iron flange duct has two kinds of flange connection and flangeless connection. Stainless steel angle iron flange duct is galvanized steel duct flange made of angle iron, is a kind of duct connection. Generally large stainless steel angle iron flange duct, small duct without flange. Stainless steel angle iron flange duct, also known as no flange duct, its production form is faster than the traditional rectangular duct processing speed.
Stainless steel angle iron flange duct according to the material: generally: steel duct (ordinary steel), galvanized sheet (white iron) duct, stainless steel duct, glass fiber reinforced plastic duct, plastic duct, composite material duct, color steel sandwich insulation board duct, double-sided aluminum foil insulation duct, single-sided color steel insulation duct, coated with adhesive tape duct (such as mining air duct), mining plastic duct, and so on.
Stainless steel angle iron flange duct is a thin steel plate flange connection, stainless steel angle iron flange duct is suitable for medium and high pressure ventilation, air conditioning system. Stainless steel angle iron flange duct is duct production, installation of stainless steel angle iron flange duct traditional connection, has long been stainless steel angle iron flange duct workers most of the projects used. Stainless steel angle iron flange duct is widely used. But the stainless steel angle iron flange duct processing and installation process is complex, stainless steel angle iron flange duct to be welded from four angle steel, and then placed on the punch punch rivet holes and bolt holes.
When the thickness of stainless steel angle iron flange duct is less than 2mm and the duct’s edge size in less than or equal to 2000mm, stainless steel angle iron flange duct between the use of riveted flange. When the duct plate thickness is less than or equal to 1.2mm. Angle steel flange and the duct of the use of welding, which results in material loss, time-consuming and labor-intensive, but also airtightness is not good, on-site installation is inconvenient and difficult to hoist the shortcomings of leisure.
