Galvanized steel sheet duct: one of the earliest used ducts, made of galvanized steel sheet, suitable for the transportation of general gas with small moisture content, easy to rust, no heat preservation and noise elimination, long installation and installation cycle specialty.
Inorganic FRP duct: newer type of duct, made of glass fiber reinforced inorganic material, non-combustible, corrosion-resistant, heavy in weight, hard but brittle, susceptible to deformation and cracking due to self-weight, no insulation and noise reduction performance , production and installation cycle is long.
Composite fiberglass duct: In recent years, the type of duct is based on centrifugal fiberglass board, inner glass fiber cloth, and outer moisture-proof aluminum foil cloth (the imported sheet is internally coated with heat-sensitive black acrylic polymer, and the outer layer is thin. Cloth / aluminum foil / kraft paper), after drying with a fire-proof adhesive, and then made by cutting, grooving, bonding and other processes, according to the section size of the duct and the pressure of the wind, appropriate reinforcement measures are adopted.
Fiber fabric duct: often referred to as bag duct, duct duct, fabric duct, fabric air distributor, is the latest type of duct, is a flexible air distribution system woven from special fibers (Air Dispersion) is a kind of air outlet end system that replaces traditional air supply ducts, dampers, diffusers, and heat insulating materials. It is a wind-end end system that is mainly capable of uniformly supplying air by a unique air outlet mode of fiber penetration and orifice jet.
It has surface airflow, large air volume, no blowing feeling; uniform distribution of overall air supply; anti-condensation; easy to clean and maintain, healthy and environmentally friendly; beautiful high-grade, diverse colors, individualized and outstanding; light weight, roof load can be neglected; Quiet operation, improved environmental quality; simple installation, shortened engineering cycle; flexible installation, reusable; overall system cost savings, high cost performance and other advantages.
Shandong ventilation pipe http://material grade is generally distinguished by use
1. Air duct for purifying air conditioning system: galvanized sheet, stainless steel; (FRP and composite materials that may be contaminated by dust source during use are prohibited)
2. Air duct for central air conditioning system: galvanized sheet, color steel insulation board; (glass fiber reinforced plastic, composite material can be used)
3. Air duct for environmental control system: galvanized sheet, stainless steel; (plastic, glass steel, composite materials can be used)
4. Air ducts for industrial ventilation systems: steel plates and galvanized sheets; (Libo ventilation pipes. Plastics, glass reinforced plastics, composite materials can be used) Note: FRP ducts can be divided into organic and inorganic types, and fire protection requirements are required according to design specifications. Disable organic materials;
5. Air duct for special use occasions: mine coated rubber duct and mining plastic ventilation pipe; (requires flame retardant antistatic mining safety features)
The company is mainly engaged in the design, production and installation of ventilation ducts. It has introduced advanced air duct automatic cutting production line, plasma cutting machine, shearing machine, biting machine, pressing machine, rounding machine, bending machine, Flange forming machine, etc. More than ten sets of ventilation equipment processing machinery, with professional HVAC designers, high-level sheet metal production staff, skilled installation and construction team, standardized, standardized, high-quality engineering quality and high-quality management In the completed project, we have won the praise of our customers.
Heat Shrinkable Sleeves provide great corrosion protection, Superior resistance to Cathodic Disbondment and excellent durability against abrasion and chemical attack. The result is effective, wide application, easy to operate and preheating temperature low (50 °C) ,long term protection against corrosion.High performance adhesive provides excellent resistance to Cathodic Disbondment to ensure long-term corrosion protection.Just-in-time customized lengths allow bulk rolls to be field cut to protect any pipe size.
