Production and use requirements of slip on flanges

When producing slip on flanges, steel plates shall not be directly machined into neck flanges, and they shall be fabricated and processed by certain processes. Steel plates for slip-on flanges shall be ultrasonically inspected without delamination defects to ensure good quality and prevent performance problems that may occur during use. Production and inspection shall be carried out in accordance with certain quality requirements to make sure that there are no quality problems in the steel plates.

Compared with other kinds of flanges, a slip-on flange saves space during use, has lower weight, and most importantly, it has very good sealing performance which ensures no leakage on the head part. The reason why the size of the slip-on flange is reduced is that the diameter of the seal is decreased, which will lessen the cross section of the sealing surface.

In addition, the flange gasket has been replaced by a sealed ring to ensure that the sealing faces are matching, so that only a small pressure is required to press the cover tightly. And the size of the bolt is cut down as the required pressure is reduced, and the number of bolts required is correspondingly reduced, a new product with a relatively small volume and light weight is finally designed. The high-pressure flange is mainly used in the installation of pipelines, whose connection is an important connection method for connecting pipes in pipeline construction. High-pressure flange connection is to fix two pipes or equipment on a flange respectively, then add a flange gasket between the two flanges, and fasten them together with bolts.
