With the rapid development of blind flange domestic long-distance pipeline construction, pipeline pressure test to become an important part of the essential, before and after the pressure test, each line must be Pigging, the number is usually 4 to 5 times . Especially after the pressure test, the water in the pipeline is difficult to be cleaned, the cleaning frequency will be more. Using the closing ball at the construction method of repeated soldering head, and its problems: firstly, to increase labor intensity; Second Repeat method of welding consumables head high, you need more than the number of large-scale equipment, and high cost. For Pigging When the long-distance pipeline pressure test quality stainless steel blind plate prices in the tee with large appearing repetitive labor-intensive method of welding head, supplies high, more often need large equipment and high cost problem, A new simple quick blind flange construction method. The construction method describes the structure of the fast opening blind, working procedures and strength check. By applying the astringent ninglam gas pipeline project, proved quick blind construction methods to improve efficiency three times higher than repeat the welding head construction methods, not only to reduce the labor intensity, but also reduces costs. Use flanged real meaning is to have a good seal connecting role, it can be very effective to protect the entire pipeline smooth and sealed. The effect is so large flange connection, not only can enhance the efficient seal, but also can be disassembled blind carbon steel plate supplier for secondary use and cleaning. Of course, the flange is not blind generic product manufacturing factory is divided into pressure levels, the different pressures in the pipeline, on the container or equipment, are to be matched, there is also the conduit to the connecting material matched with each other, but at any place and engineering, one pipe flange is also essential for different environments play an unusual role in this film is the role of the flange and principles.
