Heating Free-standing Steel Chimney

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 heating free-standing steel 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 Free Standing Steel Chimney is connected through the bottom flange, directly fixed on the bottom base, there is no fixed device appearance.

Product Description

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.
