Installation method of flange heating pipe

Flange electric heating tube is also called bundle heating tube. It is formed by fixing 1, 2, 3 or multiples of 3 U-shaped tubes on a flange. Because of its high thermal efficiency and easy installation, it is often used for water tanks, oil tanks and boiler heating. Although the shape of flange electric heating tube is complicated, it is very simple to install. Today we will take a look at the installation method of flange electric heating tube. Flange electric heating tube is divided into two types: flat flange and threaded flange, and threaded flange is divided into threaded and reverse threaded.

1. Flat flange heating tube

A. First open a hole in the heating container. (The aperture is generally larger than the outer diameter of the flange heating tube)

B. Then weld the external tube outside the hole. (The aperture of the external tube is equal to the aperture of the opening)

C. Then weld the female flange to the external tube. (The female flange is matched with the flange on the heating tube)

D. Fix the flange on the flange heating tube with the female flange with screws, and add a sealing ring in the middle.

2. Threaded flange

1. Threaded flange electric heating tube

A. First make a hole in the heating container.

B. Then weld the female tooth ring outside the hole. (The female tooth ring is matched with the thread of the heating tube)

C. Just screw the electric heating tube on the female tooth ring.

2. Reverse threaded flange heating tube

A. First make a hole in the heating container. (The hole diameter is equal to the thread diameter of the heating tube)

B. Then pass the threaded part of the reverse threaded flange electric heating tube from the inside of the container to the outside.

C. Screw the hexagonal nut on the thread of the electric heating tube and add a sealing ring.
