Self-supporting Single Sleeve Steel Chimney
The self-supporting single sleeve steel chimney has only one layer of barrel material, and the barrel material is usually Q355B material. The barrel should not only ensure the structural load, but also ensure the anti-corrosion of the inner barrel (the inner wall of the barrel can be sprayed with anti-corrosion coating). Suitable for a height not exceeding 50 meters; Chimney with low corrosive smoke and low flue gas temperature. New construction process of self-supporting single-sleeve chimney:
(1) Before the construction of chimney works, technicians should carefully do a good job of concrete test allocation, in order to obtain a better mortar mix ratio in line with the compressive strength of the design scheme;
(2) Under the precondition of soliciting the willingness of the owners of the community and the technical department, the water-reducing agent such as retarding agent is added to the concrete to increase the initial setting time and improve the compactness of the joint part of the concrete virtual beam;
(3) The insertion point layout of the vibrator should be symmetrical, and the vibration strength time length should be suitable to ensure that there is no leakage vibration, but vibration;
(4) The bleeding water and floating slurry caused by the whole process of concrete pouring should be discharged immediately, and it is forbidden to infiltrate into the concrete structure, so as to prevent harming the compactness of the base concrete structure itself;
The maintenance of concrete surface and side must be carried out in accordance with the safety operating procedures to prevent the closing of gaps.
Features of self-supporting single-sleeve chimney:
1. Stainless steel corrosion resistance
2. The service life is more than 30 years
3. Stainless steel self-supporting chimney light weight can be prefabricated
4. Stainless steel independent chimney insulation performance is good
5. Stainless steel self-supporting chimney appearance is bright and smooth, coordinated with modern buildings.
Self-supporting single sleeve chimney range:
Self-supporting single-sleeve chimneys belong to a kind of industrial chimneys, mainly used in the fields of waste incineration industry, light industry, coal industry, power plants, chemical plants, boiler flue gas emission and so on.
