Connection of various standard pipe fittings
Thread Content
American and national standard pipe fittings are often used in projects. It is very troublesome to connect them. They often fail to connect and are confusing. Please ask experts for advice.
This needs to be solved from the source, and the pipe fittings of that specification must be considered during engineering design.
The inability to connect is a design problem. Of course, the key to different sizes and specifications cannot be connected.
The uniformity of the use of standards should be emphasized in design and procurement!
There will be problems connecting pipe fittings of different standards, such as American standard NPT threaded pipe fittings. If you use the national standard GB7306 threaded pipe fittings, they will not match.
A frequently encountered problem is that although the design can specify the use of a series of pipes and fittings, special equipment, valves, and instruments are often encountered, and their flanges may not necessarily match the series selected for design. In actual projects, connections between different systems are often encountered. We often encounter imported special valves, and it is difficult for foreign manufacturers to manufacture them according to our standards. The general solution is: 1. For flange and pipe connections between different systems, the flange should be WN, which needs to be specially manufactured, and the neck should be processed according to the pipe specifications. 2. The connection between pipes can be made by making special reducers or through flanges.
Just add some non-standard pipe fittings. This requires careful design and attention. There is no way to change the different specifications and standards.
Mainly in the design, not thorough consideration.
Fittings and pipes must be of the same standard.
