DP
ROCCHEGGIANI DP
The complete and versatile Roccheggiani stainless steel flue material is suitable for the production of solid flue ducts. They can be widely used, like the DP series. A double-walled version with 25 mm insulation (50 mm available on request). With an inner diameter of 80 to 300 mm, this programme offers a wide range of applications for individual flue gas extraction from high-efficiency boilers and non-condensing boilers, stoves and fireplaces with solid fuel (wood, pellets). But the DP series can also be used for flues of large central heating plants. The DP series has a sleek and shiny polished appearance, so that it can be used along the facade.
DP Specifications
The inner housing of the DP series is made of AISI 316L stainless steel, the outer jacket is made of highly polished AISI 304 stainless steel. In between is 25 mm of high-quality mineral wool insulation (50 mm for the DP 50 series) of high density that offers excellent thermal protection under all conditions. The pressed insulation does not sag, guaranteeing the same overall compressive strength.
In addition to high-quality stainless steel and insulation, the DP series has a number of other distinctive specifications:
- Silicone sealing ring with triple seal, with inner diameters of 80 and 100 mm as a standard, larger diameters on request.
- With silicone ring for applications with positive pressure (P1) and at an operating temperature up to 200°C.
- Without silicone ring for applications with negative pressure (N1) and at an operating temperature up to 600°C.
All benefits of the DP series at a glance
- Heavy-duty quality, all interior diameters are 0.5 mm thick, stainless steel AISI 316L. Exterior wall is made of AISI 304 stainless steel.
- High-quality, high-density thermal insulation that does not sag and guarantees the same overall compressive strength.
- Extremely durable and safe because the T-pieces are made without a welded joint, providing maximum corrosion resistance. Equipped with a triple silicone sealing ring as standard for the 80 and 100 mm types, larger diameters on request.
- Rapid and stable assembly because each component comes with a strong clamping band with two grooves to guarantee the stability of the connection.
- The Roccheggiani DP series is TÜV-, CE-, NF (DP 25)- and IMQ Quality CIG-certified.
