Composition and knowledge of flat welding flange with neck

Under the rapid trend of the market economy, all fields have gained equal and better growth. The competition in the market of pipe fittings is also intensifying. As the bottom of the middle and lower reaches of the field of food materials, medicine production, and packaging, the harm of pipe fittings is also increasing. We should pay more attention to it

Because the neck Angle is low, the bending stiffness and bearing capacity of the neck flat welded flange are gradually improved, and the spot assembly is more convenient and popular. It is a more commonly used flange type

So, let's understand with neck flat welding flange is composed of several parts, with neck flat welding flange basic principle is what. Next, I will give you a brief introduction to the neck flat welding flange, so that you can master it.

There are many problems with neck flat welded flange

That is, compared with butt welding flange, flat welding flange with a neck has a large number of welding tasks, high electrode consumption, and can not withstand high temperature and repeated bending and temperature fluctuations.

And relatively speaking, the cost of a flat welded flange is higher. Because of the characteristics of its style, it is easier to get hurt on the road, which is also necessary to pay special attention to the selection of a flat welded flange with the neck.

Flat welded flange with neck
