What is Butt Welding Flange?

Butt Welding flange is also called high neck flange. It differs from flat welding flange in that there is a long and inclined high neck from the flange welding side to the flange. The wall thickness of this high neck along with the height and the direction gradually transitions to the thickness of the pipe wall, which improves the discontinuity of stress and thus increases the flange strength.

Butt-welded flanges are mainly used in places with severe working conditions, such as where the pipe undergoes thermal expansion or other loads that cause the flange to undergo greater stress or repeated stress changes; pipes with large fluctuations in pressure and temperature or high temperature, high pressure, and Sub-zero temperature pipes.

1. How to make sure the raw material is real material which we need?
  Firstly, we have our own casting foundry. We control our products’ quality start from raw material. The proportion of fixed raw materials, professional operation process, and detection of spectrometer imported from Germany.

2. Can we laser marking our logo or others on the pipe fittings?

  Yes, it is acceptable.

3. Can we require custom packaging, such as color boxes, etc?

  Yes, certainly. It depends on how many quantities do you need. It also will increase the total cost.
