In the 21st century, with the continuous progress of society, the production methods of our various products have grown rapidly. Don't say something too wide, say we see the pipes. With the progress of modern society, more and more materials are used in pipelines, but if you don't understand the knowledge of pipelines, you may step on thunder, so understandQingdao galvanized iron ductIt is also necessary, so, let's understand the production requirements and characteristics of Qingdao galvanized iron duct together!

Appearance inspection: Qingdao galvanized iron duct is very strict in the production of plates, profiles and other main product materials. Welds shall be visually inspected for defects such as pores, blisters, chips and cracks. The deformation of the steel plate after welding needs to be corrected.

Material production: Qingdao galvanized iron duct made of polystyrene foam board. The density of the foam board should be: 403/m3. The thickness is 35%, and the surface temperature should be above 5. The junction of the edge of the insulation layer adopts a step or two-way structure and is pasted with resin. Cover the outside with aluminum foil cloth and stick it tightly with thermal adhesive tape. There shall be no condensation outside the air duct.

Neat and smooth: Qingdao galvanized iron duct and air outlet are connected by thermal insulation hose. Dendrobium candidum air duct installation should be flat and straight, the main air duct installation is not vertical 1.5/m, unevenness 1/m. The surface of the iron sheet and accessories needs to be flat, uniform arc, dislocation of longitudinal joints, tight biting joints, and uniform width.

Deviation for making metal fittings: allowable deviation for outer diameter or outer length of contact pipe and metal fittings: -1 below 300; Above 300, it is -2mm. Install silencer elbows at all right angle corners in the duct system, with galvanized iron fins in the silencer elbows. The iron sheet air duct adopts mechanical bite, regular, and glass glue is applied to the inner surface of the interface.

　　Qingdao galvanized iron ductCharacteristics

In addition to the advantages of good rigidity and high strength, it also has the performance of sound absorption and noise reduction, heat preservation and heat insulation without secondary heat preservation, which overcomes the weak strength of traditional composite air ducts and the weak points of easy damage of external walls, and gives full play to the advantages of galvanization., Long service life, and beautiful and elegant inner insulation material is non-combustible phenolic foam in organic materials. After the pipe is formed, it does not need secondary heat preservation, and has antibacterial and noise elimination function, pipeline production shall be guaranteed by mechanization, high quality and high efficiency.

Industrial production and processing contains a variety of polluting gases, if not discharged into the room, it will affect the health of workers, so the existence of iron sheet is necessary, can help air circulation, but many people complain that the construction of iron sheet is difficult, but in fact did not master the technology.

1. Before construction, the chief equipment engineer will draw the pipelines of various types of work on a plan with a single line. Each tube uses a colored pen. Integrate the elevation at each intersection to see if there is any contradiction, find it in time, and solve the problem before installation.

2, to solve the collision coordination principle of all kinds of ventilation pipes, the general use of "small pipe to large pipe, pressure to make no pressure". When the water pipe collides with the pipe, the water pipe shall be bent; when the cold and warm water pipe collides with the sewage pipe, the cold and warm water pipe shall be replaced.

3. In order to reduce investment, save space and reduce floor height, when laying pipes without slope, tap water pipes and fire spray drying pipes can be laid through beams.

4, for more complex civil buildings, in the design stage, heating, water supply and drainage, power supply and lighting and real estate experts should negotiate space separation, determine the elevation range of each iron ventilation pipe, generally speaking, can not exceed the limits of their own decision, individual pipe section transit should be negotiated with other projects of ventilation pipes.
