Lap joint flange refers to a flange loosely sleeved on the flange of the container or pipe, which belongs to steel parts. The flange is the connecting part between the shaft and the shaft, which is used for the connection between the pipe ends; The flange on the inlet and outlet of the equipment is also used for the connection between two equipment.
Lap joint flange is Lap joint flange. The flange can be made by flanging, directly turning out or otherwise welding the ring. The advantages are that the flange deformation does not produce additional torque to the container or pipeline, and the manufacturing is convenient. It can be made of materials different from the container or pipeline, which is convenient to save precious metals. It is suitable for vessels or pipelines with brittle materials and low pressure.
Lap joint flange often uses flanging and steel ring to cover the flange on the pipe end, and the flange can move on the pipe end. The steel ring or flange is the sealing surface, and the function of flange is to press them tightly. It can be seen that the Lap joint flange is not in contact with the medium because it is blocked by the steel ring or flange. The lap joint flange is actually equivalent to the combination of two kinds of flanges. The lap joint flange is a movable flange piece, which is generally matched on the water supply and drainage fittings (the most common one on the expansion joint). When leaving the factory, there is a flange at both ends of the expansion joint, which is directly connected with the pipeline and equipment in the project by bolts.
