Long Weld Neck Flange

Long Weld Neck Flange (LWN) is an extended form of butt welded flange with a neck, whose neck height is significantly higher than that of ordinary butt welded flanges. The neck is usually designed in a straight cylindrical shape, and the height is adjusted according to the nominal diameter (DN): when DN ≤ 100, the neck height is 229mm, and when DN>100, it is 305mm. The thickness of the neck wall gradually transitions to the thickness of the pipe wall, effectively improving the stress distribution, enhancing the rigidity and bearing capacity of the flange, making it suitable for working conditions with high pressure, high temperature and frequent temperature changes.

Rubber Flexible Joint Flange

The rubber flexible joint flange is a part used to connect pipes and equipment together. It consists of two parts: a flexible rubber joint and a flange. Rubber flexible joints are usually made of rubber materials and have good elasticity and sealing properties. In addition, they can also absorb the vibration and displacement of the pipeline to protect the pipeline from damage. On the other hand, a flange is a metal part used to connect pipes or equipment, with one or more protruding edges (i.e., flange faces) for bolting with other flanges or parts.

Threaded Flange

Threaded flanges are flanges with internal or external threads that are connected by screwing the threads on the flange to the threads on the pipe or equipment against each other. This type of flange is usually used in low-pressure and low-temperature operating environments because of its relatively low connection strength, but easy installation and removal.
