In the pipe installation, the three way, the elbow, the big head and the flange do not need the quota?
In industrial pipe installation, three - way, elbow and big head should be calculated separately.
In industrial pipe installation, three - way, elbow and big head should be calculated separately.In the installation of the plumbing and heating pipe, the three way, elbow and big head need not be calculated, and the quota has been comprehensively considered.Flanges are divided into industrial pipes and civil pipes.The industrial pipeline, regardless of flange on the pipeline flange is connected with the valve, apparatus, equipment, containers are to be calculated separately, measurement unit is "deputy"; the device is connected, or flanges in the pipeline plugging, to "slice" as the unit of measurement, but the quota should be multiplied by a factor of 0.61.In the plumbing pipe, every flange used for the pipeline connection needs to be calculated separately, and the measurement unit is "vice"". Flanged valves include the flanges and bolts, nuts, and gaskets required to connect the valve. The flanges do not need to be counted.
Clamp, three links, four links, elbow, reducer can be directly fixed in the pipeline inside the material content. Three pass, four pass, elbow, big head need not coat quota. Above DN100 shall be also included in the wood, do not need another coat of quota. As a result of different standards throughout the country, the key is whether the set of fixed pipe installation includes pipe fittings, first look at the specifications, engineering calculation rules, and then set the quota, there will be no duplication of calculations and omissions.Method of setting quotas:1.. What project quantity sets what quota, find the amount of project quota that you need first.2. understand the base price. The price is fixed in artificial materials machinery (+ +, it is note that units) are now consumption quota, consumption is the loss of quota book has made it clear that each of the different material loss, this loss is fixed price price * material.3. price conversion. If the artificial, material, machinery in a price change will require a change to the original conversion price, the price deducted from the price, then the changes added to form a new price.
