How to calculate the cost of installing one square meter of ventilation ducts?

The material of the ventilation duct is not the same, the ventilation duct has a white iron sheet with single-sided galvanized and double-sided galvanized, **are not the same, they are all made of the size of An, **look at the material, one square meter is not expensive more than 70 packages of public package materials. The labor cost of ventilation duct installation is determined according to the difficulty of on-site construction How much is a square meter, it is recommended to find the manufacturer to ask for specific **. Generally, it is necessary to combine their own needs in order to determine the specific**.

According to a class of urban engineering, the price of galvanized steel plate main material is calculated according to 30 yuan square, all costs are calculated, labor 42 yuan, 230 yuan square; 3 categories 198 yuan; If there is a difference between the material and the price you calculate, you can add or subtract it appropriately, and the artificial flight is basically around 20 yuan. It is the most cost-effective to find someone to process it yourself and then find someone to package the installation.

There are many kinds of ventilation ducts, and the classification of folding uses generally includes: purification system return air duct, air conditioning ventilation pipe, industrial air supply and exhaust ventilation pipe, environmental protection system suction and exhaust duct, mine extraction gas pipe, mine adhesive cloth duct, etc.; Shape classifications generally include: round, rectangular, spiral; It is also divided into equal angle iron flange air duct and common plate flange air duct; It is not clear for each specific type, but the most commonly used galvanized steel air duct is 38-42 (yuan) m2, which should be determined according to the situation of the construction site, such as the size of the construction area, elevation, etc.

Production and installation of indoor ventilation, fresh air ducts, various smoke exhaust and exhaust ducts, processing of aluminum alloy tuyeres and round flanges; All kinds of special-shaped ventilation ducts.

Precautions for the installation of ventilation ducts: when the air duct is connected with the fan, a soft joint should be added at the air inlet and outlet, and the cross-sectional size of the soft joint should be consistent with the air inlet and outlet of the fan. The hose joint can generally be made of canvas, artificial leather and other materials, the length of the hose should not be less than 200, the tightness should be appropriate, and the flexible hose can buffer the vibration of the fan.

When the air duct is connected with the dust removal equipment and heating equipment, it should be prefabricated and installed according to the actual surveying and mapping drawings after the equipment is installed. When the air duct is installed, the inlet and outlet air should be opened when the air duct is prefabricated, and if the air outlet needs to be opened on the air duct after installation, the interface should be tight. When transporting gas containing condensate or high moisture content, the horizontal pipe should be equipped with a slope and connected to the drainage pipe at the low point.

Longitudinal seams should not appear at the bottom of the air duct during installation, and the joints at the bottom should be sealed. For the steel plate air duct that transports flammable and explosive gases, a jumper wire should be installed at the connecting flange of the air duct and connected with the electrostatic grounding network. How much is a square meter of ventilation duct installation to combine with their own needs in order to determine the specific.

In the way of directly installing the exhaust fan, the industrial exhaust fan is installed on the window of the plant, the specifications are selected according to the size of the window, and the number of units is determined according to the area of the plant, which can achieve the effect of air circulation in the plant. Duct ventilation system, according to the actual situation of the plant, the duct ventilation system should be designed. The above two methods, the way of directly installing the exhaust fan, have low investment, easy installation, and good results.

The duct ventilation system has a large investment, complex installation and long installation period, which is a targeted ventilation effect. The above two methods have their own characteristics, and they mainly depend on their own situation and capital budget.

How much is the labor cost of ventilation duct package soundproof cotton and anti-imitation fire board.

If only the installation does not include the production, the labor cost is about 30 50 yuan, if the installation height is relatively high, the cost will be more. Under normal circumstances, the installation of ventilation ducts can be contracted without materials, or contracted with materials, if it is their own processing or purchase ventilation ducts and then find someone to install them, this is more cost-effective.

The size of the tube is related, the small tube ** should be high, on the contrary, the large tube is cheap, only about 40 60

This depends on your project, if the project is large, it will naturally be cheaper, and it should be calculated according to the amount of your project, the completion time, and how many workers are needed. Like Zhengzhou, generally more than 100 square meters of hotels to install ventilation equipment, from pipe assembly, to pipe installation, testing whether the ventilation pipe is qualified, so the steps, at least two or three days, this depends on the number of your engineering personnel, two or three days about two or three engineering personnel. Of course, the more people there are, the faster the project will be completed.

The labor cost of one square meter of air conditioning ventilation duct is about 50 yuan.

About 40 to 60 people per square meter is too high.

Air conditioning and ventilation ducts are contracted for light processing of about 50 yuan per square meter, which adds processing fees and installation costs. This is the ** of 2015 and is now estimated to be around 100.

At the same time, the response varies according to different engineering quantities and different places.

Ventilation duct is a metal or non-metallic pipe used in ventilation and air conditioning engineering of industrial and civil buildings, which is a kind of municipal infrastructure that is used to circulate air and reduce the concentration of harmful gases.

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

Under normal circumstances, you must not exceed the limits you have set for yourself. If you cross the boundaries of a single pipe segment, you should consult with other projects. The principles for solving the collision coordination of various ventilation ducts are generally:

Small pipes give way to large pipes, and pressurized pipes give way to no pressure". For example, if a water pipe collides with an air pipe, the water pipe should turn. If the hot and cold water pipes collide with the downspout, the hot and cold water pipes should be replaced.

Prior to construction, the equipment master engineer should draw piping and single lines for each type of work on the floor plan. Use colored pens for each pipe. Integrate the elevation of each intersection to see if there is any contradiction, find it in time, and install it after it is solved.

In fact, the labor cost of ventilation duct installation is not generalized, and it is closely related to the level of local economic development, but the overall range will not fluctuate too much.

How much does it cost to install a square meter of ventilation ducts?

Good evening, dear kiss is very happy to serve you, for you to inquire about the ventilation duct installation labor cost of about 30 50 yuan square meters. If the installation height is relatively high, the cost will be higher. I hope my answer will be helpful to you!

Hello, the installation of the cabin hospital ventilation pipe contractor light processing of about 50 yuan per square meter, these money plus processing fees and installation costs. At the same time, the response varies according to different engineering quantities and different places.

Light installation pipes, nothing else.

The labor cost of installing the pipeline, regardless of anything else, is about 30 yuan square meters.

Kiss!Hello, happy to answer your <>

Pro, the labor cost of installing a square meter of ventilation duct is 50 yuan, and it is generally "a small pipe to let the old god respect the pipe, and there is pressure to let there be no pressure". The installation requirements are as follows: when the ventilation duct is installed horizontally, the allowable deviation of the horizontality is not more than 3mm, the total deviation is not more than 20mm, and when the ventilation duct is installed vertically, the permissible deviation of verticality is not more than 2mm per meter, and the total deviation is not more than 20mm.

The distance between the pipe rack and the flange should not be less than 20 chamber meters. The length of the flexible short tube is 150-300 mm. Metal and non-metallic hoses must not exceed 2 in length and have no dead bends or collapses.

The distance between the hanger and the branch pipe of the main ventilation duct should not be less than 200 chamber meters. The blind calling distance between the flange bolt hole and the low-pressure air source is not more than 200mm, and the distance between the medium-pressure air source is not more than 100mm. Elbows, tees, and valves of ventilation ducts must be equipped with hooks.

The length of the pipeline is not less than 15, and the anti-rolling bracket is not less than one guard. Hope mine can help you <>

Summary. The calculation of ventilation ducts is based on the floor area, that is, the area of ventilation ducts required per square meter of floor area. According to different building types, the calculation method of ventilation duct area is also different, generally speaking, the ventilation duct area of residential buildings is per square meter of floor area, and the ventilation duct area of public buildings is per square meter of floor area.

The above is all my reply, I hope it can help you and I wish you a happy life.

You are very happy, I am happy to answer for you, the following is the answer for your inquiry, I hope to help you in general, the labor cost of installing a square ventilation duct is about 200-300 yuan, and the specific ** depends on the actual situation.

Ventilation ducts are calculated according to the floor area and the area of the pipes.

How to common plate flanges and angle iron flanges.

Plant. The common plate flange shouted with a laughing angle iron flange** is generally more than yuan square meters is my line crack all replied to Zheng Han, I hope to help you, I wish you a happy life.

This is calculated based on the floor area or the area of the pipeline.

Hello, the labor cost of installing the ventilation pipe is usually calculated according to the area of the pipe. Because the ventilation duct is curved, it has a different floor area and area. Floor area refers to the actual area of the pipeline within the building, while area refers to the area after the pipeline will be placed.

Since the area of the ventilation duct can more accurately reflect the difficulty of the project and the labor cost, the labor cost is usually calculated according to the area. Warm reminder: At present, the epidemic situation has been relaxed, but you still have to wear a mask when traveling, I hope that my change is enough to help you <>
