Outside the high-pressure pipe elbow pipe installation with the installation of high-voltage, low-pressure pipe installation requirements similar, but more demanding, more stringent regulations, and therefore GB Cr9Mo socket elbow, unless required to meet the medium and low pressure piping installation requirements, yet shall The following requirements to perform. Used to install the high-pressure pipe, fittings, fasteners and valves must have passed the test, along with the corresponding technical documents for sale cheap Cr9Mo socket elbow, should keep transported to the scene, clearly marked, placed neatly. Cr9Mo socket elbow before installation, it should be the inner and outer surfaces wipe clean, and check whether the channel foreign body is smooth. Check the nozzle and gasket sealing surface roughness meets requirements, may not affect the sealing performance of the sealing surface scratches (scratches, especially radial), spots and other defects.
