There is a silicone sealing ring inside the hoop. Therefore,it has good sealing pergormance and good strength and rigidity.Moreover,the hoop is very convenient to disassemble and install because of its simple structure.It can be opened and closed in a short time,and it is convenient and quick to use,and its shape is also very beautul.Because there are fewer joints of the hoop.And welding is very low,and the installation time is only one third of that of that of similar pipes.There is no burr on the surface of the hoop,which has good environmental protection performance and good use effect.1.The sealing performance is good, and the air leakage rate is very low compared with the ordinary flange-connected air duct. 2.The installation and disassembly are very convenient and fast, and the maintenance is very convenient, saving a lot of costs.1Introduction to duct clamps Duct clamps (Ductclamp), also known as duct clamps, are commonly known as quick flange devices. Duct clamps are actually a kind of pipe material component, which is specially used to hold or clamp a pipe to another kind of pipe material component. It belongs to the fasteners among hardware. Duct clamps are suitable for round ducts, which are flangeless ducts connected by clamp connection. They are composed of locking mechanism, sealing ring, duct and clamp. The clamp is in the shape of "_", which corresponds to the convex edge of the duct end, and is fixed by the locking mechanism. The duct clamp uses a new type of flange mechanism without external convexity, which perfectly uses the arc of the clamp to wrap the convex edge of the duct end. The connection is extremely tight, the sealing effect is very good, and it is very practical and convenient. The duct clamp series products are actually quoted from the advanced technology of Europe and the United States. The special processing equipment developed by the top technology of Europe and the United States after many years of research and development is used to produce circular flanges.It is perfectly and widely applicable to the connection of various circular air ducts, perfectly replacing the previous iron round flanges. It is a replacement product for iron round flanges. Its advantages are unmatched by iron round flanges. European and American designers use standard component design, and flexibly match various pipe fittings, and use clamps (clamps) flanges and other connection methods to connect them into conveying pipelines of any form and direction. This design is widely used in industrial fields such as exhaust, dust removal and powder transportation. It is an advanced pipeline transportation technology in these fields. At present, most developed regions such as Europe, America and Southeast Asia have begun to widely use this technical design. Because the system is not only simple and quick to install, but also easy to disassemble and maintain, and has very good sealing performance, it can largely replace the current flange connection pipeline system in my country. The duct clamps are made of galvanized and stainless steel, and can be customized with special specifications.
