Products Description


1. Butt welding flange with neck
It is more commonly used in our high-pressure equipment and pipelines, which are made of copper, aluminum, steel, stainless steel and other metals. Neck flange welding is commonly referred to as a "high hub" flange. The purpose is to transfer the pressure of the pipeline, thereby reducing the high stress concentration in the flange base. Neck flange welding is designed to weld those flanges that are currently provided due to their inherent structural value. This is expensive because of the design.
2. Flat welding flange with neck
Flat-welded flanges are suitable for the connection of steel pipes with a nominal pressure not exceeding 2.5MPa. The sealing surface of flat-welded flanges can be made into three types: smooth, concave-convex and tongue-and-groove. Application of smooth flat-welded flanges. Multi-purpose In the case of relatively mild media conditions, such as low-pressure non-purified compressed air, low-pressure circulating water. The neck height is low, and its rigidity and load-bearing capacity are improved. Compared with butt-welded flanges, the welding workload is large, the electrode consumption is high, and it cannot withstand high temperature and high pressure, repeated bending and temperature fluctuations, but the on-site installation is more convenient.
3. Other flanges
The sliding flange has a lower hub because the pipe enters the single flange before welding. It is welded inside and outside to provide enough strength to prevent leakage. The sliding flanges are matched to the outer diameter of the pipe. It is better than the welding of the neck flange; the socket welding flange is a similar sliding flange, and the diameter of the smaller hole is matched with the same pipe with the same ID. The restriction is a built-in hole that stays at the bottom as a shoulder sleeve designed for pipes. This eliminates any flow restrictions when using socket welding flanges.
