What Should Be Paid Attention to When an Elbow Is Installed?
An elbow can change the direction of straight pipes in pipeline construction, so it is widely used in pipeline construction. Because different types of elbows are required for different environments, there are many types of elbows. Generally, elbows are made from stainless steel, alloy steel and carbon steel. According to the production process, an elbow can be divided into a welding elbow and a stamping elbow. The nominal pressure of an elbow is 1 to 1.6Mpa, and angles of the ordinary elbow are 45 degrees, 90 degrees and 180 degrees. An elbow is widely used in infrastructure projects such as chemical industry, construction, water supply, drainage, petroleum, pipelines, power, etc. There are many points for attention when it comes to elbow installation, because the elbow is directly connected to the straight pipe. If you are not careful during installation, it may cause leakages. Matters needing attention are as the following:
1. Keep an elbow clean and keep it properly. If the elbow is used for a long time, it must not be left unattended for a long time. It is necessary to check and maintain the elbow regularly. Clean up the working surface that is frequently touched, and then put the elbow in a dry place to avoid it being corroded.
2. Make preparations before installation. Please carefully check the various standards of stainless steel elbows before installation. For example, whether the diameter of the elbow meets the requirements. If there is a problem with the elbow, please deal with the problem before completing installation of the elbow.
3. According to the use position, the stainless steel elbow can be installed directly on the pipeline. In this case, it can be installed anywhere in the pipeline. In order to simplify the operation and maintenance of the elbow, please note that the stainless steel elbow can only be installed horizontally. Please pay attention to tightness of the stainless steel elbow when installing, so as not to affect the leakage and normal operation of the pipeline.
4. Please evenly tighten the sealing and pressing bolts of the valve. The ball valve is connected with an elbow. The gate valve is only fully opened or closed. Flow adjustment is not allowed; the sealing surface is corroded, and wear is accelerated. The screws of the internal valve and globe valve are relative sealing parts to prevent the sealing ring from leaking to the tightening position of the handwheel screw.
5. Damaging the valve parts should be avoided for the elbow, and be careful not to use levers and other management tools; use the hand wheel reasonably to ensure correct operation.
