Large flange in the process of use due to the large flange connection time or improper use of long years and presents the status of the leak, appear this kind of condition the user need not anxious. First look at the leak site, minimal in general due to the large flange connection leak site clearance can't eliminate leakage after clearance injecting sealant. Seal construction method based on the leakage location survey of field stop, to complete the limited block, using the fixed clamp method to accommodate funnelled and constitute a sealed cavity, injecting sealant, so as to eliminate leakage. Side of the clamp are made of, jig to satisfy large flange funnelled hold go, sets up the body of large flange and pipe large flange connecting nipple between the large flange seal chamber to the point. To avoid because of pressure-out make body and large potential leakage of flange clearance leakage again, in the jig and the large flange anastomotic set to the outer ring cavity injection glue. Because of the large diameter flange during agent injection fixture against trail large flange lateral displacement, the limit of the tooth contact card is adopted tightening measures. In the operation of the sealant in the cured after effect view, stop part of injection pressure, avoid stress relaxation, blocking agent injection hole again.

The large flange advertent items:

Large flange with prescribed in the consumption and use of technical requests and technical parameters, in accordance with the provisions of the way and the way of consumption and processing: hebei large flange

1. The large flange should be along the direction of steel rolling cut into strips, the bending welded into a circular ring, and constitute a ring cylindrical steel appearance. In the consumption of large flange shall not adopt steel machined directly into a large neck flange, with specified process manufacturing and processing.

2. The consumption of large flange plate should be via ultrasonic testing, with no defects, guarantee the good quality and performance issues, in accordance with the provisions of the quality request of consumer and inspection, ensure the quality of consumption and use steel plate no problem.
