How about stainless steel spiral air duct and where is good? Nowadays, with the development of the information age, many people can know which manufacturers they are from without going out, but even with a lot of information, it is indeed difficult to choose. We still need to go to the site to understand the positioning of this manufacturer, as well as the application cases and so on. What about choosing stainless steel spiral ducts? Where is the best place to choose? When choosing a manufacturer, you need to find one that is reliable and has a good reputation. Next, let's take a look at the customer service introduction of the spiral duct manufacturer.

Specifically introduce the production and manufacturing conditions of stainless steel spiral ducts, including raw materials such as strip steel coils, welding wire, and flux. Strict physical and chemical tests must be conducted before investment. The head and tail of the strip steel are connected using single or double wire submerged arc welding, and automatic submerged arc welding is used for repair welding after being rolled into a steel pipe.

Before forming the stainless steel spiral air duct, the strip steel undergoes leveling, trimming, planing, surface cleaning, conveying, and pre bending treatment. The use of electric contact pressure gauges to control the pressure of the oil cylinders on both sides of the conveyor ensures the smooth transportation of the strip steel. Adopting external or internal control roller molding.

Adopting a weld seam gap control device to ensure that the weld seam gap meets the welding requirements, the pipe diameter, misalignment, and weld seam gap are strictly controlled. Both internal and external welding are performed using electric welding machines for single or double wire submerged arc welding, in order to achieve stable welding quality. The welded seams are all inspected by an online continuous automatic damage detector, ensuring the coverage of non-destructive testing for spiral welds. If there are and spray marks, production workers can adjust the process parameters in real time and eliminate them in a timely manner. Use an air plasma cutting machine to cut steel pipes into individual pieces.

After cutting into individual steel pipes, each batch of steel pipes must undergo a strict pre inspection system to check the mechanical properties, chemical composition, fusion condition, surface quality of stainless steel spiral ducts, and non-destructive testing of the welds. Only after ensuring that the pipe manufacturing process is qualified can it be officially put into production. The parts with continuous sonic inspection marks on the weld seam shall be manually rechecked by X-ray. If confirmed, they shall be repaired and undergo non-destructive testing again until they are confirmed to have been removed. The pipe where the butt weld seam of the strip steel and the T-shaped joint intersecting with the spiral weld seam are located shall be inspected by X-ray television or film. Each stainless steel spiral air duct undergoes a hydrostatic pressure test, and the pressure is sealed radially. The test pressure and time are strictly controlled by the steel pipe water pressure microcomputer detection device. Automatic printing and recording of experimental parameters. Mechanical processing of pipe ends to accurately control the perpendicularity, slope angle, and blunt edge of the end face.

What should we do if there is damage during the entire process of installing stainless steel fusion ducts? Let's take a look together below. The use of stainless steel welded air ducts plays a very important role in people's daily lives, because stainless steel spiral air ducts can effectively change the gas conversion between indoor and outdoor environments, endangering the gas inhaled by people.

With the continuous development trend of manufacturing industry and technology, many manufacturing industries that did not use stainless steel spiral ventilation ducts in the past have just begun to apply them. If the product is damaged, it can be repaired with sealant; If the aluminum foil layer on the outer surface of the pipeline is damaged, but the glass fiber insulation layer is not damaged, qualified aluminum foil sheets can be used to repair the aluminum foil surface of the pipeline.

If the damaged fiberglass insulation layer has been reached, the damaged area can be cut off, and another complete board can be selected and cut according to the specifications of the cut glass panel. Then, brush repair glue and adhesive on the surrounding sockets, and seal them according to the processing technology standards. When the product is working normally, it needs to be checked regularly to prevent work delays.

Briefly describe the installation and construction conditions of stainless steel duct engineering: Generally, the installation of ventilation ducts for stainless steel duct exhaust systems and air conditioning systems must be completed on the roof of the building, and the obstacles at the installation site must be cleared.

The pipeline installation of the air purification system should be carried out under the conditions that the floor of the relevant parts of the building is clean, the walls are plastered, and there is no large area of dust indoors. The installation of the general Chen dust system air duct needs to be carried out after the installation of the process equipment related to the air duct in the factory has been completed, and the position of the equipment connection or suction/exhaust hood has been determined.

The ducts, components, and accessories composed of stainless steel ventilation and air conditioning system pipelines have been processed and passed quality inspection. Closely cooperate with civil construction. The installation holes and embedded support components that should be pre drawn are all intact and have been inspected to meet the design requirements. The preparation work for the construction of stainless steel air ducts has been completed, such as the availability of construction tools, lifting machinery and equipment, scaffolding or lifting installation platforms that meet the construction requirements.
