Tower Type Corrosion Resistant Steel Chimney

Tower Type Corrosion Resistant Steel Chimneys manufacturers believe that the chimney of dry smoke discharge serious corrosion in the upper part of the chimney, affected by outdoor air, easy to form coagulative acid. Lined chimney, corrosive medium easy to invade the part, one is the intersection of the lining section, such as the support of the outer cylinder; Secondly, the flue gas medium through the gap of brick masonry: into the outer cylinder and lining between, and then corrosion of the outer wall.

Tower Type Corrosion Resistant Steel Chimneys manufacturers consider that wet chimneys and wet (semi-dry) chimneys with corrosive exhaust should be made of or lined with corrosion-resistant materials. According to different working conditions, different anticorrosive materials and different structural forms can be used:
1. The flue and chimney with serious corrosion can be made of plastic, acid-resistant stone, acid-resistant brick, glass steel, stainless steel, alloy steel, titanium plate and so on. According to different corrosive media and working conditions.
2. For mildly corroded chimneys, acid-resistant concrete and coated lining can be used.
3. For the chimney with serious corrosion, it is generally not suitable to use the brick outer cylinder. In chemical industry, metallurgy, papermaking, boiler chimney corrosion after forced demolition examples, corrosion basically occurred when the outer barrel is brick masonry. Brick chimneys (including lined ones) are difficult to reinforce after corrosion and prone to instability due to local corrosion.

Generally speaking, wind load is the main lateral load of tall buildings, and often exceeds the seismic force as the decisive load. As the instantaneous wind speed can be divided into average wind speed and pulsating wind speed, the effect of wind on towering structures is also manifested as the average wind load downwind, pulsating wind load downwind and the interference force caused by the helical detachment of the transverse wind. The static wind load caused by the average wind speed can be calculated according to the method provided in the Code for Load of Building Structures; For the wind vibration part, refer to the current domestic general expression as follows: downwind vibration force: P along = and -4 shape
1. Transverse wind vibration force: P transverse =k and -1 to W.
2.Tower type B wind vibration coefficient;
3.Tower chimney size coefficient: from the wind pressure along the height of the change coefficient: W.
Basic wind pressure: k The ratio of transverse wind and downwind wind vibration force is equal to the ratio of root mean square value of acceleration response of transverse wind and downwind. At present, the domestic theoretical and experimental research on the tower truss tower mainly focuses on the steel tower of the transmission circuit. The domestic literature shows that the downwind effect and the cross-wind effect are roughly equivalent, and in the same order of magnitude. It is concluded that the value of k ranges from 110 to 1105, and the average value of k is 1112. The value of k is closely related to the structural form, and different shapes have different values of k, so aeroelastic model test is needed to determine the exact value. Wind vibration coefficient B is the key parameter for calculating the wind effect of the structure. The test in a literature shows that for the 182m high transmission tower structure, wind vibration coefficient increases monotonically with the wind speed, and the design wind speed v=3613Ws

Hebei Pude Yuelan Environmental Protection Equipment Co., Ltd. is an enterprise engaged in the development and production of industrial chimneys, the company focuses on the development and production of industrial chimneys.

Headquartered in Jingxian Development Zone, Hebei Province, the company has a registered capital of 60 million yuan, covers an area of 9.60000 square meters, of which the building area is 2600 square meters. The main products include self-supporting smoke, sleeve smoke, tower chimney, east smoke, cable smoke, stainless steel chimney, glass steel chimney, mobile compressed garbage bin, horizontal compressed garbage station, hook arm transfer truck, butt type garbage truck and dozens of products. The company has 128 employees, including 8 experts and engineers with master's degree or above, 60% of the employees with bachelor's degree or junior college degree, all kinds of technical personnel 26 people, 60 people special personnel, the company has a number of domestic offices and after-sales service institutions, can provide technical support and product services at any time.
 
The company's production equipment advanced, strong technical force. Has more than 50 sets of domestic advanced production equipment, including foreign, domestic CNC production lines 6; Hot-dip galvanizing adopts the galvanizing technology and process of Gimeco Company in Italy, and its technical level and production capacity are at the advanced level in China.

After years of development in chimney and municipal waste treatment equipment industry, the company has become a well-known brand in the industry. Through the cooperation with domestic and international design institutes, colleges and enterprises to continuously improve the enterprise's scientific research and development ability. And has cooperated with many universities and reached strategic cooperation with petrochina, Sinopec, Huadian, Huaneng and other enterprises.

In recent years, in order to solve the problem of large-caliber smoke, the company has established a technical cooperation relationship with Beijing Jiaotong University, and invested a lot of manpower and material resources to develop the "precast factory, on-site construction" steel corrugated chimney and urban waste environmental treatment products. At present, the pipe diameter range of the company's products is 0.5m-20m, and the annual production capacity is 660,000 meters.

The company always adhere to the "quality, user" of the enterprise purpose, do not ask for the number of projects, just do the project to make good quality principle, products have been promoted in the project use. Today, the company's products still maintain zero defects, zero complaints, zero accidents, by the owners, construction units of the consistent praise, and establish a long-term cooperative relationship.
