Selection and installation of metal pipe fittings

Metal pipe connector is a kind of high quality flexible pipeline in modern industrial pipelines. It is mainly composed of bellows, mesh sleeves and gaskets. Its inner tube is a spiral or ring shaped thin-walled stainless steel corrugated tube, and the outer mesh sleeve of the corrugated tube is woven by stainless steel wire or steel belt according to certain parameters. The joints or flanges at both ends of the pipe are matched to the joints or flanges in the customer's pipeline. The corrugated pipe of the pipe is formed by high precision plastic processing of seamless or welded stainless steel pipes with extremely thin walls. Due to the elastic properties of the contour of the bellows, the pipe has good flexibility and fatigue resistance, which facilitates the absorption of various cyclic loads of movement and deformation, especially in the pipeline system, which has the ability to compensate for long journeys. Media visualization (media visualization), process automation.

The metal pipe fitting is composed of a metal pipe body, a stainless steel wire mesh sleeve and a gasket part. In the marine pipeline system, it is mainly used in the connection between the pipeline and the equipment where the pipeline fluid is petroleum or fresh water.It can compensate for a certain relative displacement and achieve the reducing effect vibrations and noise. However, if the selection is incorrect, not only the effect of vibration isolation and noise reduction will not be achieved, but the damage of the metal pipe will lead to problems such as pipeline leaks and even failure of the pipe. 'equipment.

The selection of metal pipe mainly includes the correct selection of parameters such as diameter, connection type, working pressure, temperature correction, minimum bend radius and pipe length. The diameter, type of connection and operating pressure depend directly on the requirements of the piping system. Usually there is no problem. It should be mentioned that when selecting the design pressure of the pipe (which should be higher than the working pressure of the system), it should not be too high, because as the load capacity of the pipe increases, its bending capacity is considerably reduced. The temperature correction and minimum bend radius are set for the product and are given by the manufacturer. What often gives us problems is the selection of the length of the metal pipe. Too long a hose will cause instability, increase resistance to flow, as well as additional mechanical damage and vibration issues. If the pipe is too short, it may not be able to achieve vibration compensation and reduction, eliminating the noise will also cause excessive bending stress and affect the service life.
