Rubber joint in the pipe connection pipe need to do the preparation work before.
Rubber joint in the pipe connection to what method?Rubber joint with the piping or equipment is known to all the cohesion between method is very important, it is no good cohesion method can directly affect the pipeline rubber joint happened to run, run, drip, leak of representation.Common rubber joint cohesion method contains: flange connection, connect to the clamp, butt welding, thread cohesion, card sets, clamp, cohesion, since the sealing connection mode, etc.According to the practical experience for many years, elevation and slope of reasonable arrangement of pipeline, and try to avoid even the appearance of airbags, at the same time the inevitable appearing airbags to set exhaust valve and exhaust pipe exports meet to benefit for the exhaust system.For the second question, in the process of construction should be the prevention work of a few aspects: the first is in front of the welded steel pipe installation shall be mechanically or artificial remove dirt and rusty spot, when after the pipe inner surface is clean, the pipe mouth closed stay put.Pipeline construction in the process of not closed mouth to do temporary plugging, lest dirt to enter, pipe connection to clear in time when welding slag and linen, silk and other sundry.Second, network lowest place to install a larger drain valve.If the drain valve is too small, poor drainage effect, the cleaning times more;If the outlet is not the lowest, the sewage is not complete.Pipe installation should be appropriate to establish temporary flush valve, filter and bypass before connecting device, combined with the water pressure test in subsection cleaning equipment.Cleaning after the completion of the work, but also in circulating water system commissioning, the purpose is to network the dirt washing concentration to filter, and then to unpick and wash the filter to remove dirt.
