Information

Butt-welded flanges with neck are flanges with taper neck and are butt-welded with cylinder or pipe.It belongs to integral flange.

 

Because of the transition structure of the cone neck and the butt welding connection, the strength and stiffness of the flange are strengthened, and the sealing performance is better than that of the flat-welded flange.

 

 

1. Position the joint first.

 

2. Install the sealing ring, inside the sealing sleeve and in the sleeve taper hole.

 

3. Install the sleeve. Grease is applied to the contact parts of the sleeve inside and the sleeve cone for easy installation.

 

4. To install bolts and spherical nuts, grease should be applied to the spherical surfaces and threads for installation.

 

5. The nuts must be tightened gradually and evenly in a diagonally sequential manner and ensure that the sleeve has a symmetrical position.

 

6. The torque wrench shall be used to tighten the nuts according to the torque required in the product manual.
The slope of the neck outside of butt welding flange should not be greater than 70.Strictly control the technical parameters of butt-welded flanges during production and welding to ensure that they can play a full role and value in production and use.
