Q: What are low-pressure stainless pipes?
A: First, low-pressure pipe installation includes all the processes the content of straight pipe, not including low-pressure nozzle pipe connection process, pipeline installation arranged according to the material, welded items, "10m" for the units of measurement.
Second, the low-pressure carbon steel pipe, stainless steel low voltage, low voltage and low voltage non-ferrous metal pipe steel pipe, low non-metallic pipe, installation of cast iron pipe used in the production do not include the installation of pipe fittings, fittings installed by the design implementation of pipe connected to the related amount of subheadings .
Third, the low-pressure pipe lining including pipe, pipe fittings, flanges content of the installation and dismantling all the processes content, "10m" for the units of measurement.
Fourth, a variety of pipeline installation volume according to the design center of the length of pipe to "extend the meter" basis, without deduction of the valve and the proportion of various tube length; case of bending, pressing the two cross the centerline of the intersection calculation. Quantity should be the main material amount of the corresponding subheading calculation.
Fifth, the heating tube installed inside and outside the tube were calculated quantities, the implementation of appropriate projects.
Sixth, threaded pipe joints include the head, fill the contents of the core installation, which can not be calculated. |
