Heating Free-standing Steel Chimney

Flange connection is the two pipes, pipe fittings or equipment, respectively fixed on a flange plate, and then add flange pad between the two flanges, and finally use a bolt to pull the two flanges tightly together. A connection can be made between a stationary pipe and a rotating or reciprocating device.

Flange connection can be generally divided into five kinds: flat welding, butt welding, socket welding, loose sleeve, thread.

The following are the first four kinds of detailed elaboration:

1. Flat welding: only welding the outer layer, do not need to weld the inner layer; Generally used in medium and low pressure pipelines, the nominal pressure of pipelines is lower than 0.25MPa. There are three kinds of sealing surface of flat welding flange, which are smooth type, concave and convex type and tenon type. Among them, smooth type is the most widely used, and the price is affordable and cost-effective.

2. Butt welding: the inner and outer layers of the flange should be welded, generally used in medium and high pressure pipelines, the nominal pressure of the pipeline is between 0.25 ~ 2.5MPa. The sealing surface of butt welding flange connection is concave and convex, and the installation is more complex, so the labor cost, installation method and auxiliary material cost are relatively high.

3. Socket welding: generally used for nominal pressure less than or equal to 10.0MPa, nominal diameter less than or equal to 40mm in the pipeline.

4.Loose sleeve: generally used for low pressure but the medium is corrosive in the pipeline, so this kind of flange corrosion resistance, the material is mainly stainless steel.

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.
