If it is the sixth volume quota of industrial pipeline or pump house pipe group, the corresponding pipe fitting quota shall be set according to the pipeline quota (only the main material is different for different pipe fittings).
Question 2: How to determine the quota of grooved pipe fittings? 10. The groove part has been included in the pipeline construction quota. Just determine the price of the main material.
Question 3: The installation quota of grooved pipe fittings can be seen from the installation quota of this province. At present, there are two cases, 1, which have perfect groove installation quota and do not need casing parts. 2. The other is the groove connection of steel pipe and clamp installation, and only the main material is calculated for other pipe fittings.
The basis is quota description and calculation rules.
Question 4: Do you need to install grooved pipe fittings? Grooved pipe fittings such as T-joint, P-head and P-mechanical pipe fittings have been included in the subtitle of clamp connection. Trough fittings are the main material cost, not labor cost.
1. According to the drawings, calculate the number of various fittings of grooved pipe fittings multiplied by the unit price of each variety. This is a complicated calculation, but it is the most accurate;
2. Calculate the attachment content according to the pipeline length, then multiply the unit content by the quoted comprehensive unit price, and make comprehensive calculation according to the pipeline length in the final accounts;
3. Change, because groove fittings are added around the elbow; The actual quantity needs to be multiplied by the determined unit price.
The labor cost for installation of grooved pipe fittings has been included in the quota for installation of grooved pipes, and the labor cost is no longer taken for installation of grooved pipes.
Question 5: How to set the quota of pipe fittings in pipeline trench connection? Which subtitle, such as Guangxi Pipeline Trench Installation Quota, already contains the contents of pipe fittings, just fill in the corresponding unit price. In other places, the quota is generally only a supplementary quota, regardless of labor costs, only the cost of pipe fittings.
Question 6: How to determine the groove connection quota of galvanized steel pipe? I don't understand Zhejiang quota, so I suggest you take a closer look at the calculation rules of quantities in the chapter of quota, which should be explained.
Question 7: Which quota of pipe clamp connecting sleeve directly includes the quota of "installation of grooved pipe clamp connecting pipeline", and the installation fee of pipe fittings (including clamps and snap rings) has been included in the quota, and the main material fee should be calculated after calculating the number of pipe fittings according to the drawings.
Question 8: There is no need to recalculate the fittings used in fire fighting pipelines separately. Does the quota include the general situation: the threaded connection does not need to be calculated separately, and the threaded connection between the pipe fitting and the fire hydrant system does not need to be calculated separately when the groove is connected. The layout of water fire pipeline and the quantity of auxiliary materials in your fire protection project are calculated according to the design. See the quota description below.

The quota in this chapter is applicable to the arrangement of pipes, various components, fire hydrants and pressure water tanks of automatic sprinkler systems in industrial and civil buildings. 2. Boundary division: 1. Indoor/outdoor boundary: 1.5m is the boundary of building exterior skin, and the valve is the boundary of entrance. 2. The boundary between the pipeline between the fire pumps in high-rise buildings and this chapter is the external wall skin between the pumps. 3. Pipeline installation quota: 1. Including a one-time hydrostatic test in the process. 2. Galvanized steel pipe flange connection quota, pipe fittings shall be subject to products, and both ends of elbows shall be subject to short pipe welded flanges. This quota includes all installation procedures of straight pipes, pipe fittings and flanges, but the main materials of pipe fittings, flanges and bolts shall be calculated separately according to the design regulations. 3. This quota is also applicable to the laying of galvanized seamless steel pipes. 4. The placement quota of nozzles, alarm devices and water flow indicators shall be considered according to the pipe network system after pressure test flushing, and the quota has included the placement, removal and amortization of plugs and temporary short pipes. Five, other alarm devices are suitable for rain, dry and wet and pre-action alarm devices. 6. The installation quota of temperature-sensitive water curtain device has included all the installation contents of pipes, fittings, valves and nozzles between water supply tee and nozzle, but the main material quantity of pipes is calculated according to the design pipe center length and additional loss; The number of nozzles is calculated according to the design quantity plus the loss. 7. Placement position of the heat collecting plate: When there are holes and loopholes above the floor of the overhead warehouse, the heat collecting plate should be set above the nozzle. 8. If the anchor bolt is considered as the equipment belt in the allocation quota of isolated air pressure water tank, the quota includes guiding the use of secondary grouting, but the cost of secondary grouting is calculated separately. Nine, pipe network flushing quota is considered according to the flushing water. If the hydraulic and pneumatic flushing method is accepted, it can be calculated separately according to the construction plan. Quota only applies to automatic sprinkler system. X. This chapter does not include the following artificial contents: 1. Valve and flange installation, various casing installation, pump house pipeline installation, pipeline system strength test and leak test. 2. Installation of fire hydrant pipes, outdoor water supply pipes and water tanks. 3. Install all kinds of fire pumps, pressure stabilizing pumps and secondary grouting of equipment. 4. Placement of various instruments and wiring, calibration and monomer debugging of valves, water flow indicators and pressure switches with live signals. 5. Installation of various equipment supports. 6. Rust removal and oil brushing for pipes, equipment and flange joints. 7. System debugging. Xi。 Other relevant regulations: 1. The quota for installing pipelines between pipelines and in pipe corridors shall be manually multiplied by the coefficient 1.30. 2. The main structure is the steel formwork construction project for site pouring acceptance: the internal and external pouring quota is manually multiplied by the coefficient 1.05, and the internal and external masonry quota is manually multiplied by the coefficient 1.03. Rules for calculation of quantities 1. Pipeline laying is based on the design pipeline center length, and the unit of measurement is 10m, without deducting the length of valves, pipe fittings and various components. The quantity of main materials shall be calculated according to the quota, and the pipe fittings are shown in table 1. Table 1 content table of galvanized steel pipes Unit:10m ┏ ┏ ┙ ┙ ┙ ┙ ┙ ┙ ┙ ┙ ┙ ┙.
Question 9: How to set the quota of pipe fittings such as clamps and bends when connecting pipe fittings in fire sprinkler engineering? The contents of threaded pipe fittings have been comprehensively considered in the subtitle, and the clamp pipe fittings you mentioned have a special subtitle, so you only need to measure them according to the actual situation. For example, the elbow installation you mentioned consists of 1 clamp elbow and 2 rigid clamps. Because the main materials of these two clamp fittings are different, you should set up two subheads to reflect them.
Question 10: Trench connection between fire hydrant pipeline and pipeline installation sleeve 05 Which subtitle Volume 7 Supplementary quota for fire pipeline installation: Trench connection steel pipe.
Note: 1, grooved steel pipes, including steel pipes, grooved fittings, grooved flanges, flange bolts, etc. .
It should be said that this subtitle includes all the work contents of installing steel pipes, grooved fittings, grooved flanges and flange bolts.
2. Grooved pipe fittings generally refer to grooved elbows and tees, which are connected by groove connection.
You are a dead scholar and hopeless. There will not be a pipe trench installation quota for each volume. Set of quota, mainly depends on the construction technology, the brain should be flexible, not on the quota points that volume. You can call the local cost station if you don't believe me. If their explanation is not like this, I will give you 200 points.
