Flange connection is a detachable connection

Flange manufacturers tell flange purchasers that pressure vessel flanges are usually used for the temperature and pressure conditions of low and strong corrosive media. When strong corrosion. Rare integral and pressure vessel flange, butt welding flange flange. It is generally used for connecting low-pressure pipes upward. General method for flange connection of pressure vessels, which can be connected to rods with nominal pressure lower than 2.5MPa. Smooth connection, concave convex type and tenon groove joint can be applied to different situations.

The bolts used for flange connection should use the same specifications and be installed in the same direction, that is, the nuts should be on the same side. The connecting valve bolts and nuts shall be on one side generally. Tighten the screws symmetrically and evenly with moderate elasticity. The length of tightening bolts and nuts shall not exceed the same. The positions of pipe flange screw holes at both ends shall be the same. The positions of screw holes on pipe flange connection shall match the corresponding equipment or pipe flange screw holes in mm or 2 ~ 3 BUCKLES later. Flange connection shall be kept coaxial, the deviation of bolt hole center shall not exceed generally, and the bolt shall pass freely.

Our flange connection is a detachable connection. There are three modes of flange sealing surface for flange connection: plane sealing surface, suitable for occasions with low pressure, and the medium is non-toxic; Concave convex sealing surface of flange connection, suitable for occasions with slightly higher pressure; Tenon sealing surface, suitable for flammable, explosive, toxic media and high pressure conditions. The gasket for flange connection is a ring made of a material that can produce plastic deformation and has a certain strength.
