Question 1: How to set the quota for pipe fittings in pipeline trench connection, and which subheading should be set? Pipe fittings such as: grooved clamps, grooved tees, grooved elbows, mechanical tees, and mechanical crosses are divided into pipe types: if you apply for the pipeline quota in Volume 8, the pipe fittings are comprehensively included in the quota. In addition, remember the package price

If it is an industrial pipeline or a pipe set in a pump room with a quota in Volume 6, the corresponding pipe fitting quota will be set according to the pipeline quota (different pipe fittings only have different main materials)

Question 2: How to set the quota for grooved pipe fittings? The 10-point groove fittings are already included in the quota for pipeline construction. Just determine the price of the main material.

Question 3: Check the quota for installing grooved pipe fittings. Just know the installation quota in this province. At present, there are two situations. 1. If there is a complete groove installation quota, there is no need for casing fittings. 2. The other is the groove connection of steel pipe + clamp installation. Only the main material of other pipe fittings is counted.

The basis is the quota description and calculation rules

Question 4: Is there an installation fee for grooved pipe fittings? Grooved pipe fittings such as positive tees, large and small heads, and mechanical pipe fittings are already included in the card. Hoop connection is included in the subheading. Groove accessories are counted as main material costs, not labor costs.

1. According to the drawing, calculate the quantity of various grooved pipe fittings multiplied by the unit price of each variety. This is a very tedious calculation, but the most accurate;

2. According to the length of the pipe Calculate the content of a fitting, and then multiply the unit content by the quoted comprehensive unit price. The final calculation is based on the pipeline length;

3. Changes due to the increase in groove fittings due to bends; need to be based on the actual quantity , multiplied by the determined unit price.

The labor cost for the installation of trench accessories has been included in the trench pipe installation quota, and there is no labor fee for trench installation;

Question 5 : How to set the quota for pipe fittings in pipeline trench connection, and which sub-category should be applied. The quota for pipe trench installation in Guangxi already includes the content of pipe fittings. Just fill in the corresponding unit price. If there are quotas in other places, they usually only use a supplementary quota, and do not calculate the labor cost, but only the cost of pipe fittings.

Question 6: How to set the quota for the grooved connection of galvanized steel pipes? I'm asking for advice. I don't understand Zhejiang's quotas. I suggest you carefully read the engineering quantity calculation rules in this chapter of the quotas. There should be explanations.

Question 7: Which quota of the pipe fitting clamp connection sleeve directly fits the "grooved clamp connection pipe installation" quota? The installation fees of pipe fittings (including clamps and snap rings) are included in the quota. The main material fee should be calculated after the quantity of pipe fittings is calculated according to the drawing.

Question 8: Whether the pipe fittings of fire-fighting pipelines need to be counted separately, and whether they are included in the quota. In general: threaded connections do not require additional pipe fittings, but only for groove connections, additional pipe fittings are required for fire hydrant system threaded connections. There is no need to separately calculate the placement of pipe fittings for fire protection engineering water fire extinguishing pipes. The quantity of auxiliary materials is calculated according to the design. See the following quota explanation.

Henan 08 New List

C .7.1 Water fire extinguishing system (030701) Description 1. The quotas in this chapter apply to the installation of pipes, various components, fire hydrants, and pneumatic water tanks of automatic sprinkler fire extinguishing systems installed in industrial and civil buildings (structures). 2. Demarcation of boundaries: 1. Indoor and outdoor boundaries: 1.5m from the exterior wall of the building is used as the boundary. If a valve is installed at the entrance, the valve is used as the boundary. 2. The boundary between the fire pump room pipelines located in high-rise buildings and this chapter is bounded by the outer wall of the pump room. 3. Pipeline placement quota: 1. Including one-time hydraulic test within the process. 2. Galvanized steel pipe flange connection quotas, pipe fittings are based on products, and the ends of elbows are considered according to short pipe welding flanges. The quota includes all installation processes such as straight pipes, pipe fittings, flanges, etc., but pipe fittings, The quantity of main materials for flanges and bolts should be calculated separately according to design regulations. 3. The quota also applies to the installation of galvanized seamless steel pipes. 4. The placement quotas for sprinklers, alarm devices and water flow indicators are all considered based on the pipe network system’s pressure test and flushing after passing the installation. The quotas include the placement, removal and amortization of plugs and temporary short pipes. 5. Other alarm devices are suitable for rain, wet and dry use and pre-action alarm devices. 6. The placement quota for the temperature-sensitive water curtain device includes all the placement content of the pipes from the water supply tee to the nozzles and valves, pipe fittings, valves, nozzles, etc., but the number of main materials of the pipes is calculated based on the designed pipe center length, plus losses. ;The number of nozzles is calculated based on the design quantity plus loss. 7. Placement of the heat collecting plate: When there are holes or loopholes above the layered boards of the elevated warehouse, a heat collecting plate should be installed above the nozzle. 8. The anchor bolts in the installation quota of diaphragm-type pneumatic water tanks are considered according to the equipment. The quota includes guidance on the labor of secondary grouting, but the cost of secondary grouting is additional. 9. The pipe network flushing quota is based on water flushing. If the hydraulic pneumatic flushing method is adopted, it can be calculated separately according to the construction plan. Ratings apply only to automatic sprinkler systems. 10. This chapter does not include the following work content: 1. Valve and flange installation, manufacturing and installation of various casings, pump room pipeline installation and pipeline system strength test and tightness test. 2. Installation of fire hydrant pipelines, outdoor water supply pipelines and water tank manufacturing and installation. 3. Installation of various fire pumps, pressure stabilizing pumps and secondary grouting of equipment, etc.

4. Installation of various instruments and wiring, calibration and unit debugging of valves with electrical signals, water flow indicators, pressure switches. 5. Manufacturing and installation of various equipment brackets. 6. Remove rust and oil the welded joints of pipes, equipment and flanges. 7. System debugging. 11. Other relevant regulations: 1. For pipes installed in pipe rooms and pipe corridors, the quota shall be manually multiplied by a coefficient of 1.30. 2. For projects where the main structure is cast on-site and constructed using steel formwork: the labor quota for internal and external pouring is multiplied by a factor of 1.05, and the labor quota for internal pouring and external masonry is multiplied by a factor of 1.03. Engineering quantity calculation rules 1. Pipeline placement shall be based on the designed pipe center length, with 10m as the unit of measurement, without deducting the length occupied by valves, pipe fittings and various components. The quantity of main materials should be calculated according to the quota, and the content of pipe fittings is shown in Table 1. Table 1 Galvanized steel pipe (threaded connection) fittings content table unit: 10m┏━━┯━━━━━━┯━━━━━━━━━━━━━━━━━━━━━━ ━━ ━━━━━━━━━━━━━━━┓┃Item│ Name│ Nominal diameter (within) ┃┃ │ ├─────┬────┬────┬─── ──┬─────┬────┬─────┨┃ │ │ 25 │ 32 │ 40 ......>>

Question 9: Fire sprinkler project When connecting pipe fittings, how to set the quota for clamps, elbows and other pipe fittings? The content of threaded pipe fittings has been comprehensively considered in the subheading. The clamp pipe fitting installation you mentioned has a special subheading. You only need to measure according to the actual measurement. For example, the elbow installation you mentioned consists of 1 clamp. The elbow is composed of two rigid clamps. Since the main materials of the two clamp pipe fittings are different, you have to use two subheadings to reflect it.

Question 10: Fire hydrant pipe groove connection, pipe installation sleeve 05 quota which sub-item? Volume 7 fire pipe installation supplementary quota: grooved connection steel pipe.

Note: 1. For grooved connection steel pipes, the quota includes steel pipes, grooved pipe fittings, grooved flanges, flange bolts, etc. .

It should be said that this sub-project includes all the work of installing steel pipes, grooved pipe fittings, grooved flanges, flange bolts, etc.

2. Grooved pipe fittings It should generally refer to pipe fittings connected by groove connection such as grooved elbows and tees.

You are a person who is obsessed with reading, and there is no way to save him. Not every volume has a quota for pipe trench installation. When setting quotas, it mainly depends on the construction technology and your mind should be flexible, not on which book the quota is allocated. If you don’t believe me, you can call the local cost station. If their explanation is not like this, I will compensate you 200 points.
