Question 1: What is the quota for plastic-lined steel pipe groove connection sleeves? If it falls within the scope of industrial pipeline engineering, it should be set with the relevant quota sub-items in the quota for industrial pipeline installation projects; if it is a water supply and drainage project, it should be set with water supply and drainage. The corresponding quota sub-items for the installation of steel-plastic composite pipes in the quota book (selected according to the installation connection method).

Question 2: 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 3: For grooved flange connections, how to make a list and what quota should be used? When using grooved flanges to install valves:

1. Set grooved flanges

2. The valves should be applied to the relevant valve subheadings in process pipelines, but not to the subheadings in water supply and drainage installation.

3. Clamps are not included in the sub-item, only the main material cost is counted.

Question 4: How to set the quota for pipe fittings in pipeline trench connection, and which sub-heading should be applied. The quota for pipe trench installation in Guangxi already includes pipe fittings. Just fill in the corresponding unit price. Can. If there are quotas in other places, it is usually just a supplementary quota. Labor costs are not calculated, but only the cost of pipe fittings.

Question 5: How to set the quota for pipe fittings in pipeline trench connection, and which sub-category should be included? ? 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 cover 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 6: Fire hydrant pipe groove connection, pipe installation set 05 quota, which sub-item of 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.

Question 7: How to apply the quota for the trench connection of fire pipes in the pump room? According to the engineering quantity calculation rules, the installation of pipes and fittings in the fire pump room follows the industrial installation quota, that is, industrial Installation quotas for grooved pipes and valves and pipe fittings for pipeline installation.

Question 8: How to set the quota for the grooved connection of galvanized steel pipes? Request for advice: There are no quota sub-items that can be applied, only similar quota sub-items can be applied or supplementary quotas can be prepared.

Question 9: How to set the quota for steel-plastic composite pipes (grooved clamp connection)? Pipes have a wide range of applications. Pipes are used in many industries.

Different industries have different characteristics and thus have different technical requirements.

Pipe is a relatively mature product, and each industry has corresponding technical standards.

To detect pipes, select the corresponding product standards according to the industry in which the pipes are used, and detect the corresponding technical indicators according to the needs of the industry.

Generally, there are dimensional indicators, inner diameter, outer diameter, and wall thickness.

Strength index, the strength index of pipes includes radial compressive strength, that is, ring stiffness, flexibility index, bending index, impact strength, etc.

For pipes used for drinking water, then It has its hygienic technical indicators and water pressure resistance indicators.

The communications industry also has its own technical requirements.

Question 10: Quotas for installation sets of grooved pipe fittings. Just look at the installation quotas of 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
