Flange, also called flange flange disc or flange. The flange is a part connected between the shaft and the shaft, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures.

High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, the weld is made of the base metal melt from the body, the mechanical strength is better than the general pipe. Smooth appearance, high precision, low cost weld high and small, favorable 3PE anti-corrosion coating. There are significant differences in the welding methods between high frequency welded pipe and submerged arc welded pipe. As the welding is done instantly at high speed, the difficulty of ensuring the quality of welding is much higher than that of submerged arc welding.

Titanium tube has light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and conveying pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units.

Pup jointis a pipe of non-standard length used to adjust the length of tubular strings to its exact requirement.
