Code for construction of ventilation pipe insulation

1. For complex civil buildings, in the design stage, all types of work (HVAC, water supply and drainage, power supply and lighting and construction) should first negotiate the space separation and determine the elevation range of each pipeline.

2. The principle to solve the collision and coordination of various ventilation pipes is generally: "Let small pipes make large pipes, so that there is pressure but not pressure". For example, if a water pipe collides with an air duct, the water pipe should rotate. If the hot and cold water pipes collide with the sewer pipes, the hot and cold water pipes should be replaced.

3, air conditioning engineering refrigeration system pipeline, including refrigeration equipment and air conditioning water system insulation engineering construction, should be in the pipeline system strength and rigor inspection and anti-corrosion treatment.

4. Before construction, the equipment manager engineer should draw the pipelines of various types of work on the floor plan. Use a colored pen for each pipeline. Synthesize the elevation of each intersection to see if there is any contradiction, find it in time, solve the problem and then install it.

5. In order to reduce investment, save space and reduce height, some pipes without slope requirements can be laid through beams (such as water pipes and fire sprinkler pipes). ).

6. All joints should be installed in inconspicuous places as far as possible to ensure the beauty.

Extended data:

According to materials, ventilation pipes generally include: steel plate ventilation pipe (ordinary steel plate), galvanized steel plate ventilation pipe (white iron), stainless steel ventilation pipe, glass fiber reinforced plastic ventilation pipe, plastic ventilation pipe, composite material ventilation pipe, color steel sandwich insulation board ventilation pipe, double-sided aluminum foil insulation ventilation pipe, single-sided color steel insulation ventilation pipe, tape-coated ventilation pipe (such as mine air duct) and plastic ventilation pipe for mining.

Generally, it is classified into: return air duct of purification system, central air conditioning ventilation duct, industrial air supply and exhaust ventilation duct, environmental protection system air suction and exhaust duct, mine gas drainage duct, tape mine ventilation duct, etc.

The air duct is mainly used in industrial and architectural engineering, and its application fields mainly involve: the clean system of clean workshop in electronic industry, the clean system of sterile workshop for medicine and food, the central air conditioning system in hotels, shopping malls, hospitals, factories and office buildings, the exhaust duct for dust removal, smoke exhaust and oil absorption in industrial pollution control, the air supply duct for comfortable industrial environment or post, the gas drainage system for gas drainage in coal mines, the return air system for environmental control in coal mines, etc.
