As the use time increases, production Rubber hose 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. Rubber hose company 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.

What are the process requirements for making welded air ducts? Both ends of the expansion joint are welded to the outer wall of the air duct. production Rubber hose When the fan coil unit is equipped with two air outlets, the double-layer shutter with regulating valve should be selected. Usually only small installation space is required. Without increasing any pressure drop, a circular pipe with a diameter of 200mm in the same installation space can replace 250 × 150mm rectangular pipe. Features: The iron sheet is prone to chemical reaction in various environments, causing corrosion and rust. However, zinc hardly changes in dry air. The thermal insulation and fire resistance performance indicators of the welded air duct system shall meet the requirements of Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering (GB50243) and Technical Specification for Ventilation Ducts (JGJ141) respectively. In the ventilation system: supply fresh air and exhaust gas, exhaust harmful gas outdoors, and send outdoor fresh air indoors. This technology is widely used in various process pipelines, oil and gas pipelines in oil fields and other cleaning projects. Especially for pipeline cleaning of long-distance fluid transportation, it has advantages that cannot be replaced by other technologies. When the air leakage rate exceeds the requirements of the design and acceptance specifications, the leakage can be detected by listening, touching, observing, water or smoke, and the air leakage position can be found and marked; After repair, retest until qualified. Safety seal ring leak proof system. The exquisite spiral pressing rib technology enables the spiral air duct to have good strength under pressure, Rubber hose company With the addition of spiral ribs, the thickness of the seam is four times that of the pipe body. The rigidity of the pipe is very large, which shows the advantages of firmness. It can withstand large pressure loads without damaging deformation. The thickness of materials can be reduced by 15%, reducing costs.

production Rubber hose The inner and outer walls are smooth, the resistance of the air duct is small, the secondary noise is not generated during air supply and exhaust, the energy consumption is reduced, and the operation cost is saved. The product can be made on site, cut, drilled, and opened, the installation is simple, and the labor and time are saved. The user's investment cost is reduced, the construction period is shortened, the performance price ratio is high, and it is cheaper than other materials. After the installation is completed, no maintenance is required, and the maintenance cost is reduced. The key points of whether galvanized sheet air duct material galvanized sheet is corroded are mainly reflected in the following three aspects: ① The first corrosion of galvanized sheet in the entire service life cycle is the oxidation of the galvanized layer on the surface, resulting in white rust. After a little longer time, the white rust on the surface further reacts with carbon dioxide and other impurities in the humid air to form black spots. When the galvanized sheet is used for a long time and the galvanized layer is severely corroded, the steel base loses the sacrificial anti-corrosion effect of zinc, and begins to oxidize to generate red rust. Once the steel base begins to oxidize, the corrosion rate becomes very fast, and the life of galvanized sheet ends. ② In addition, there are two special corrosion conditions of galvanized sheet, namely, black stain. One is that after being used for a period of time, due to the influence of lead and other elements in the zinc coating, the galvanized sheet will become black in the matte part of the zinc flake. The blackened zinc coating still has a protective effect on the steel base, but has a certain impact on the service life. ③ Rubber hose company It has excellent corrosion resistance in dry or pollution-free environment. However, in the polluted environment, the service life will be greatly shortened, so it is necessary to pre coat the film into color plates before use.

Chongqing Rubber hose 1. The manufacturing quality shall be guaranteed according to the national standards of Oxygen Hose (GB/T2550-91) and Acetylene Hose (GB/T2551-91) respectively, and the hose shall have sufficient compressive strength and flame retardant characteristics. According to the national standard, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with substances such as acid, alkali, oil and other organic solvents that can damage the hose. The storage temperature shall be - 15 ℃~40 ℃, and the distance from the personnel shall not be less than 1m; 3. When using a new hose, the talcum powder on the inner wall of the hose must be blown out first to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 4. If the oxygen hose catches fire, stop the air supply first, and then deal with the fire hose, but do not bend the hose. The cylinder valve must be closed when the cylinder is not in use or after work. 5. The hose with bulge, crack or air leakage shall not be used, and the air leakage hose shall not be used after being stuck with adhesive tape.

For the woodworking industry, many users production Rubber hose Not unfamiliar, this is an industrial dust collector used on woodworking carving machines, mainly used to absorb wood chips, wood ash, etc. At present, there are many kinds of woodworking vacuum tubes on the market. In the past few years, major furniture factories used PVC steel wire hoses with flat ends. In recent years, more and more enterprises have replaced cheap PVC steel wire hoses with more wear-resistant and durable pu steel wire expansion tubes. Some of the former take a few days or a month, while some of the latter take a few months or a year, They are also steel wire hoses. Why is the service life gap so far? First of all, you may have the impression that many PVC hoses have a very bad smell. This kind of hose is often used in daily life. Because the raw material itself is very cheap, the price of the finished product is also very low. For example, only a dozen yuan a piece. Think about the price of PVC raw materials, which is generally 8-15 yuan a kilogram, And most businesses will not use expensive PVC raw materials, Rubber hose company The woodworking vacuum tube produced in this way has a very strong smell, not only unpleasant, but also many times the product can not even achieve environmental protection. However, the current updated product, pu steel wire telescopic tube, is a large woodworking furniture factory. An expensive woodworking carving machine uses a cheap vacuum tube with a very smelly smell, which has much to do with the overall style.
