Common plate flange forming machine common plate flange pipe because of its production form than the traditional rectangular tube processing speed, more convenient, less air leakage rate. Its advantage is to save material, reduce project investment; air leakage is small, reduce energy consumption, save operating costs, in the construction industry is very popular. In recent years, with the increase of the amount of pipe used as an important part of air conditioning and ventilation systems, more and more requirements are required every year. Advances in science and technology make pipe manufacturing, installation and use of new materials, new technologies emerge in an endless stream, the total flange tube is one of them. The main pipe flange factory line has become the necessary machinery and tools for large construction and installation companies while the production of ventilation pipelines has become an important factor affecting the HVAC project.
Spiral duct common flange tube, according to market materials are generally divided into three categories: galvanized spiral duct, spiral duct and composite stainless steel spiral duct. Spiral duct
a wide range. Purification system return air duct, central air conditioning and ventilation ducts, industrial exhaust ventilation ducts, suction and exhaust duct environmental protection systems, mine drainage gas pipe, mine coated cloth hairdryer and so on.
Spiral duct also has its own advantages:
1, strength and rigidity are good;
2, easy to install, less connection points;
3, Ventilation resistance is small, ventilation noise is small;
4, can replace part of the need for hot-dip galvanizing process;
5, the appearance of smooth, zinc-free tumor, burr, was silver-white;
6, good corrosion resistance, neutral salt spray test up to 240 hours;
7, the thickness is controllable, any choice within 5-107μm;
8, no hydrogen embrittlement, no temperature hazards, to ensure the same mechanical properties of materials;
9, according to customer requirements, specially designed, custom specifications duct;
10, using hot-dip galvanizing method is completed, suitable for all kinds of strong acid, alkali mist and other strong corrosive environment.
