Free-standing Heat-resistant Steel Chimney

Boiler plant exhaust flue pipe with temperature of 200°
Light weight: Although it is made of stainless steel, which has some weight of its own, stainless steel chimneys should not be too light compared to traditional chimneys. Convenient chimney transport, sales to further places, while reducing the load on the building.
Easy installation: stainless steel chimney installation is also relatively simple, convenient, even if the space between high-rise buildings is very small, it can also be easily installed, than the traditional chimney installation is simple and convenient.
Self-supporting is the surface meaning of "free-standing", simply said is not with the help of other external forces to achieve the chimney standing fixed. For example, a tower chimney is affixed with a tower outside to fix the chimney, and a cable chimney is affixed with a steel cable to fix the chimney. And self-supporting chimney, is connected through the bottom flange, directly fixed on the bottom base, there is no fixed device appearance. Self-supporting steel chimney has the advantages of good shock resistance, good corrosion resistance, economic safety and environmental protection, and can be prefabricated in the factory covers a small area, self-supporting chimney has sleeve type and multi-pipe type steel chimney, so as to increase the safety of the chimney structure. Because the smoke only contact with the inner cylinder.
Therefore, the outer cylinder wall is not corroded by flue gas, avoiding the hidden danger caused by flue gas corrosion of the outer cylinder, and the overall structure safety of the chimney is guaranteed. And avoid the chimney due to the temperature difference caused by the lining cracking problem. The insulation layer of traditional chimney is not integral, but made by splicing multiple plates. The sleeve steel chimney is very effective because of the insulation layer on the outer wall of the inner cylinder and the air layer between it and the outer cylinder wall. After the insulation layer is used, it is insulated by the air layer.
Due to the protection of the outer cylinder, the insulation layer is not eroded by the outside atmosphere and rain, so the durability is good. The smoke pipe effectively plays to the advantages of various materials. The inner cylinder is mainly used for smoke exhaust function, and the influence of wind load and seismic load is very small. Therefore, the inner cylinder can be considered separately from the corrosion resistance of the material, and the wall thickness can be designed to be relatively thin. The inner cylinder can be made of carbon steel, weathering steel or acid-resistant steel and other steel materials, and through reliable coating anticorrosion; Stainless steel inner cylinder can be used when the temperature is higher; When the temperature is low and the humidity is high, the glass steel inner cylinder can be used.

The outer cylinder is not in contact with flue gas, mainly resistant to the influence of wind and other external loads, so it can be made of ordinary carbon structural steel or weathering steel. The thermal insulation material only considers the thermal insulation effect, and does not need to consider the smoke corrosion effect. And the overall environmental protection, beautiful. Because the chimneys are all prefabricated in factories and installed on site, no construction waste is generated. When it reaches the service life, it is convenient to dismantle and can be recycled twice. Compared with reinforced concrete chimneys, steel chimneys are more beautiful and lightweight.

1. The product is safe and reliable, high temperature resistance, corrosion resistance, good heat insulation and insulation function.
2. Advanced technology, reasonable structure, stable process and reliable quality; Long service life (expected 50 years) and usually no maintenance.
3. Light weight, scientific and reasonable support combination, simple and convenient field equipment; Can greatly reduce labor intensity, reduce equipment costs.
4. Convenient equipment: the difficult and messy process of making equipment in the narrow shaft at high altitude is transformed into workshop production, integrated molding, and shipped to the site to combine equipment, which not only simplifies the equipment procedure, but also ensures the production quality problems in the inner liner, heat insulation layer and shell many links. Together, it becomes easy to assemble equipment on site.
5. Beautiful and generous appearance, can be used as a wall chimney to decorate the facade of the building.
6. Good function, it is the replacement product of brick, cement and general carbon steel chimney.

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.
