Installation Knowledge When Welding Stainless Steel Elbows And Pipes

When installing the stainless steel elbow, the stainless steel elbow can be directly installed on the pipeline according to the connection method and installed according to the position of use. Under normal circumstances, it can be installed at any position of the pipeline, but it needs to be easy to operate the inspection. Note that the flow direction of the stainless steel elbow medium should be from the bottom of the longitudinal valve disc to the top, and the stainless steel elbow can only be installed horizontally. When installing the stainless steel elbow, pay attention to the sealing to prevent leakage and affect the normal operation of the pipeline. Stainless steel elbows play an important role and value in installation and use, and have good use and operation in the corresponding environment and medium.

Below, let's explain the installation knowledge of stainless steel elbows:

1. Before installing the stainless steel elbow, carefully check the various standards of the stainless steel elbow, whether the diameter meets the use requirements, remove the defects caused by the transportation process, and remove the dirt of the stainless steel elbow. Make preparations before installation, and you are ready.

2. When installing, the stainless steel pipe fittings can be directly installed on the pipeline according to the connection method and installed according to the position of use. Generally, it can be installed at any position of the pipeline, but it needs to be easy to operate and maintain. Note that the flow direction of the stainless steel elbow medium should be from the bottom of the longitudinal valve disc to the top, and the stainless steel elbow can only be installed horizontally. When installing the stainless steel elbow, pay attention to the sealing to prevent leakage and affect the normal operation of the pipeline.

3. The bolts of the packing gland of the stainless steel elbow valve should be tightened evenly and should not be pressed into a crooked state to avoid damage to the valve stem movement or leakage.

4. When the ball valve, stop valve and gate valve of the stainless steel elbow are used, they are only fully opened or fully closed, and are not allowed to be used to adjust the flow to avoid erosion of the sealing surface. There is a reverse sealing device in the gate valve and the upper threaded stop valve. The handwheel is rotated to the upper position and tightened to prevent the medium from leaking from the packing.

Stainless Steel Weld Elbow made of stainless steel, its representative feature is that it does not rust. The feature of not rusting is that it can prevent it from being corroded, and then the liquid leaks during movement. The stainless steel elbow can be known from the name that it is made of stainless steel that is melted and then poured into a mold and dried. Its characteristics are water resistance, corrosion resistance, and pressure resistance. When welding the elbow and the cylinder, pay attention to the cleaning of the surface, and then avoid the welding slag pollutants and surface pickling caused by welding. Avoid scratches on the elbow surface, which will cause water leakage in the pipeline. Avoid iron ion pollution and oxidation. Do not place stainless steel elbows in the open air to avoid rain and moisture. Do not force them to be welded together. Stainless steel elbows must be pickled after production. Be careful not to use restoring acid for pickling to avoid material recovery.
