Stainless steel chimneys

Categorii produse


Stainless steel chimneys are an advanced solution for flue gas evacuation and can be used in both industrial and civil applications.

The stainless steel chimneys produced by our company are certified CE no. 2204-CPR-0433m, the company having implemented the ISO 9001-2015 quality management system. The warranty period is 5 years.

They are produced in two variants: single wall stainless steel chimney (SP) and double wall (DP) - insulated with basalt mineral wool. They can be used for heating units operating on gaseous, liquid or solid fuel, both inside and outside the building.


The advantages of using a stainless steel chimney are:

  • high precision components;
  • low weight;
  • low assembly volume;
  • labor and reduced execution time;
  • resistance to humidity and very high chemical corrosion.


The inside diameter of the chimney is obtained on the basis of a project made by specialized personnel. For informative purposes, the inside diameter can also be obtained with the help of some diagrams (see catalog) with the input power, the boiler type and the height of the chimney.

In no case will the diameter of the chimney be smaller than the outlet diameter in the boiler!

The inside diameters of our chimneys are: 80; 100; 120; 130; 150; 160; 180; two hundred; 225; 250; 300; 350; 400; 450; 500; 550; 600; 650 and 700.

The double wall (DP) chimney is a double-walled metal structure consisting of two concentric tubing with an insulating layer between them.

The tubes are continuously welded on generators on the WIG automatic machine. The material of the inner tube is stainless steel sheet W1.4301 (AISI304) 0.7 mm thick for Di≥400mm and 0.5mm for Di <400mm.

The material of the outer tube is stainless steel sheet W1.4301 (AISI304) with a thickness of 0.5mm.

The insulating material is basaltic mineral wool in the form of shells with a thickness of 40mm and a 0041w / mK conductivity produced by Rockwool.
