Di mana perbandingan digunakan:
1. Bekalan udara, termasuk pengudaraan, seperti bekalan udara segar dan ekzos, meliputi pelbagai, seperti udara di bengkel kilang dan tapak pengeluaran, yang perlu dibuang keluar dari bilik kerana penjanaan gas berbahaya, dan juga perlu dihantar ke bilik. Pada masa ini, it is necessary to use air transmission pipes with large flow and small pressure. Secara amnya, galvanized iron pipes are used, and stainless steel pipes are used in corrosive and especially humid places. To be careful
2. For cooling air supply, the most common is the pipe of central air conditioning, which needs to be added with insulation materials. To be careful
3. Discharge lampblack. A large amount of lampblack is produced in the kitchen of hotels, restaurants and hotels, which needs to be discharged. The round air pipe is the lampblack chimney.
A kind of ventilation pipe: it is a pipe system used for air transmission and distribution. There are two kinds of air ducts: compound air duct and inorganic air duct. Ducts can be classified by section shape and material. The production of a stainless steel air duct is to apply a sealant (such as neutral glass glue) to the seam, rivet seam, flange flange flange four corners, dan lain-lain. Before applying sealant, the dust and oil stain on the surface shall be removed. According to the section shape, the air duct can be divided into the circular air duct, rectangular air duct, flat circular air duct and so on. Antaranya, the height dimension with the smallest resistance of circular air duct is the largest and the fabrication is complex. Oleh itu, the rectangular duct is the main application. According to the material, the air duct can be divided into metal air duct, composite air duct, and polymer air duct.
