Now on the market Yantai Sandblasting pipe There are various models of galvanized air ducts. I believe you are familiar with galvanized air ducts. Do you know the main characteristics of galvanized air ducts? If you don't know, you can have a look. It will be helpful to purchase and use galvanized air ducts in the future. Galvanized air ducts refer to air supply, exhaust and smoke exhaust ducts used in hotels, shopping malls, textiles, chemical fiber, petrochemical, machinery manufacturing, instruments, electronics, medicine, tobacco, food, medical treatment, storage, office buildings, subway, civil air defense, basement and other projects. Its thickness and specification can vary according to requirements. Generally, when connecting, both ends of the galvanized spiral air duct are always externally connected to the accessories. Galvanized air duct metal air duct is made of various metal materials, commonly including galvanized iron sheet and stainless steel. With the continuous development of the tank industry at present, more and more industries and enterprises have applied to the tank industry, and more and more enterprises have entered the tank industry. Composite air ducts are composed of various inorganic materials, which can be divided into various types according to their composition, but most of them are lightweight, porous, and have large thermal resistance. First of all, the galvanized air duct is exquisite, compact, durable, beautiful, noble and elegant. The support and hanger of iron sheet air duct should be in the form and specification suitable for strength and rigidity according to the national standard atlas and specifications. The supports and hangers of extra wide, overweight and other special iron sheet air ducts with diameter or side length greater than 2500 mm shall be in accordance with the design regulations. Sandblasting pipe Where can I find it? High quality galvanized sheet is used. Condensate water pan is molded by molding process. There are no welding seams, welding spots, and thermal insulation materials (applied to industry and buildings) that meet the fire protection standards are connected to the water pan as a whole. The galvanized air duct is small in size, and the installation of drainage pipes and lines is simple and convenient. The left and right connecting pipes and return air modes can be changed at any time to match the site conditions. Galvanized air duct can be installed in any space.
As the use time increases, high quality Sandblasting pipe A large amount of impurities will accumulate in the pipeline. These impurities stored in the pipeline for a long time will accelerate the condensation of oil, form pneumatic valves, damage hydraulic components, and have a great impact on normal operation. Therefore, it is very important to clean the stainless steel welded air duct regularly. How to clean impurities in stainless steel welded air duct? When the stainless steel welded air duct is connected with the fan, the inlet and outlet shall be provided with flexible joints. The size of flexible joint shall be the same as the inlet and outlet of fan. Hose joints are usually made of canvas, artificial leather and other materials. The hose length shall not be less than 200. Sealing shall be proper. Hoses dampen fan vibration. Before the welding air duct is connected with the dust removal equipment and heating equipment, and after the completion of the equipment, the prefabrication and equipment shall be stopped according to the theoretical mapping. During equipment installation, the inlet and outlet of stainless steel welded air duct shall be opened during prefabrication. If an air outlet is required at the end of the pipe, the connection shall be closed. When transporting natural gas containing condensate or water, the horizontal pipeline shall be inclined, and the drainage pipe shall be connected at the low point. Longitudinal joints do not apply to the bottom of the pipe. Sealing treatment shall be stopped for the bottom joint. For steel plate air ducts conveying flammable and explosive gases, cross connectors shall be installed at the connecting flanges of the air ducts and connected to the electrostatic grounding grid. When the height of the horizontal airway is more than 4m, the installation personnel shall fasten the safety belt. Sandblasting pipe Where can I find it? The springboard on the scaffold or movable support shall be fixed. The width of the springboard shall meet the safety specifications. The installation personnel on the scaffold shall carry bags with them to prevent falling objects or electric drills from hurting people. After installing double hangers on the welded air duct, the cross arm shall be straight and the suspender shall not be replaced.
Industrial pollution is a signal of environmental protection. These industrial pollution must be environmentally friendly. These equipment and machinery, insulation air valve pollution sources and discharge routes must be applied to the pipeline. Yantai Sandblasting pipe It is just one of the rare ventilation ducts. Let's take a look at the precautions of stainless steel pipe welding process. Stainless steel welded air duct is called welding nano, which is a kind of welding nano. Since the thickness of the pipe is 0.8-5.0mm, welding is rare in the market (the thickness of the seamless pipe formed in the steel plant is 5-30mm), which is different. It can be said that it is a thin wall welding nano. As the thickness of welded pipe, the thickness of welded pipe may not be required to be the same as that of seamless welding, but only to meet the national standard of ventilation pipe, and at the same time meet the requirements of full pressure and air volume in the ventilation system. In the application environment, the thickness of stainless steel welded air duct pipes can be customized according to the requirements of the enterprise factory (the demander) to adapt to the processing of welded pipes. In short, as long as the above requirements are met, the cost of the enterprise will be lower. As long as the enterprise factory knows that it needs more air volume to customize and sell the fan, and then press the full pressure and air volume of the fan, the welding size of the stainless steel pipe can be determined. Because of the small wind resistance of round air ducts, ordinary air ducts are rarely used to connect environmental protection equipment. even if high quality Sandblasting pipe The air outlet of the equipment is square or round (also called square turn). Circles, heaven and earth, cylindrical dampers and circular places are connected to fans and air ducts. In this case, the circular pipe is very good for installation.
Sandblasting pipe Where can I find it? It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Yantai Sandblasting pipe It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.
Yantai Sandblasting pipe Main impact: The air volume loss of the whole system is too large to meet the air volume requirements, and the power is seriously wasted. 1. If the stainless steel welded air duct system adopts the combined flange air duct, it may be that the seam, flange strip seam and hole seam are not sealed with sealant; The allowance of segment blanking seaming is greater than the specification requirements. 2. No embedded parts are set at the joint of brick structure air duct and metal air duct, or the sealing gap is too large or the joint is not tight. Countermeasures: 1. Button type seaming can be used for medium pressure air duct; Corner seam or joint corner seam shall be used at four corners of high-pressure air duct or clean system air duct. 2. Seams of stainless steel welded air ducts, joints without flange inserts and holes must be sealed with sealing paste to prevent air leakage. 3. During construction, embedded parts shall be set at the junction of brick, structural air duct and metal air duct as required, or the civil engineering unit shall cooperate to block and seal to ensure close connection. During the air duct anti-corrosion treatment, the next anti-corrosion treatment can be carried out after the previous paint is dried; It is strictly forbidden to work without certificate. The duct type air outlet is a central air conditioning terminal air supply system that integrates the functions of air outlet, air supply pipeline, static pressure box, thermal insulation material, air valve, etc. Sandblasting pipe Where can I find it? Calculation of air duct size of stainless steel welded air duct: the equal damping method (equal pressure method) is a convenient calculation method, which is suitable for many occasions.
