Rubber corrugated compensator for air duct
Rubber corrugated compensator is a kind of non-metallic compensator. It is also different from stainless steel corrugated compensator, but the difference is mainly in use, and their functions are similar. It is mainly for the purpose of vibration reduction and noise reduction, and even for the purpose of maintenance. The following is a detailed analysis of the characteristics and functions of the rubber corrugated compensator in the lower air duct.
There are four types of rubber corrugated compensators for air duct, namely FDZ type, FVB type, FUB type and XB type, which are composed of rubber and rubber fiber fabric composite materials, steel flanges, sleeves, and thermal insulation materials. They are mainly used for flexible connection between various fans and air ducts, and their functions are shock absorption, noise reduction, sealing, media resistance, easy displacement and devices, It is an ideal accessory for shock absorption, noise reduction, smoke suppression and dust removal in the field of environmental maintenance.
There are two connection modes for rubber ripple compensation of air duct: flange connection and receiving connection. There are also four types: square type, angular type, compound type and straight cylinder type.
Rubber and fiber fabrics have good repeatability of displacement (change) recovery, can provide greater multi-dimensional compensation in a smaller size range, and can better eliminate the multi-directional error generated when various pipe devices are connected. Rubber and fiber fabrics have superior sound absorption and vibration isolation functions, which can effectively reduce and eliminate the transmission of sound and vibration of boilers, fans and other systems. The weak transmission loss of rubber and fiber fabric reduces the design process, without adding other auxiliary equipment. Rubber and fiber fabrics and heat insulation materials have high heat resistance and corrosion resistance, never rust, and reduce maintenance costs. Rubber and fiber fabrics have excellent air tightness and flexibility, and can ensure no leakage of the escort medium and recovery after repeated displacement.
The air duct rubber compensator can compensate axial, transverse and angular directions. It has the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise elimination and vibration reduction, and is especially suitable for hot air pipes and soot pipes.

Why is the quality of plastic coated pneumatic butterfly valve worried?
As we all know, plastic coated pneumatic butterfly valves are essential equipment for various chemical enterprises and large sites, and their quality must be authenticated authoritatively. However, from a broad perspective, the quality of plastic coated pneumatic butterfly valves is uneven, and sometimes the phenomenon of metal bursting occurs when the valve moves separately, followed by the unimaginable results of various gas and liquid leakage, such as the leakage of liquefied gas. How can we reduce the quality problems of plastic coated pneumatic butterfly valves?
The first thing to know is that plastic coated pneumatic butterfly valves are often constructed of corrugated pipes, metal joints and fine grids, so when welding the interfaces at both ends, various weather changes will often occur, resulting in weak welding. In fact, stainless steel metal and titanium alloy are the most recommended here, because it is important to know that titanium alloy, in particular, belongs to aviation metal, Therefore, it is the first choice for anti oxidation and anti-corrosion. Therefore, there is no such problem as acid rain, salt spray and other conditions that lead to corrosion and life loss of steel pipes.
High quality pneumatic butterfly valve connector
Behind the rapid development of modern industry, there are many new products, among which the pneumatic butterfly valve joint is a pipe that is often used in industrial consumption. Many consumers with special types of connectors can choose different types of connectors according to their own needs, and also match different consumer needs. Many pneumatic butterfly valve joints are made of stainless steel, which are popular with customers. Most of them choose this type of joint. We definitely want to buy something with good quality and material in all aspects, so pneumatic butterfly valve connectors can fully meet your different choices, and the joint structure is tight and the strength is relatively high. In addition, the tension resistance of the pneumatic butterfly valve connector is very strong, and there is no need to worry about breaking the connector due to excessive tension. Its waterproof performance is also excellent, and there has never been a case of water ingress. When choosing a product, you should choose the best and most durable one. Quality life needs to be shown in every detail.
Pneumatic butterfly valve joint is an indispensable top quality wayward pipeline in modern industry. It is generally composed of wavy rolls, joints and grids. Under normal circumstances, the inner wall of pneumatic butterfly valve connector is equipped with curved aluminum alloy metal or steel corrugated pipe, so the periphery is tightly wrapped with some stainless steel wire metal mesh pipe.
As an indispensable flexible pipeline in modern life, pneumatic butterfly valve joints are generally made of stainless steel, aluminum alloy and titanium alloy. Then the two extreme metal joints are often blue mesh joints or metal mesh sleeve joints required by customers. As the inner wall of the metal tube, the wave tube is a seamless welded inner wing ultra-thin stainless steel metal, and it is a high-precision finishing modification of the original composite. And one of the characteristics is that the wave tube has good toughness and flexibility, is not easily corroded by smoke, salt fog and acid rain, and has a long service life. The overload operation of various cycles in the application process will not show ligament problems, so the pipeline management has the condition of displacement frequency and the ability of semi-automatic and full-automatic.
