There are many ways to connect two seamless steel pipes together, but generally speaking, there are two major ways: one is detachable connection, the other is non detachable connection.
There are many ways to connect two seamless steel pipes (eg:ASTM A106 steel pipe)together, but generally speaking, there are two major ways: one is detachable connection, the other is non detachable connection.
Detachable connection refers to the removal after installation. Non detachable connection is to connect two seamless steel pipes together forever.
The most commonly used method of non detachable connection is welding. Two seamless steel pipes are welded together by various welding methods. This method costs less, but it requires higher working environment. If the pipe is too long or the diameter is too large, it is not convenient to work after welding together.
The most commonly used detachable connections are
1 Flange connection (easy assembly and disassembly, strong versatility).
2 Union connection (Union is divided into thread type and welding type)
3 Special pipe joint connection (internal thread, external thread and other forms).
Users can choose the specific connection mode according to their own situation, no matter which connection mode is used, it should be firm and reliable.
The difference between different specifications of straight seam steel pipe
There are many types of steel pipes, which can be divided into straight seam steel pipes and spiral steel pipes according to the welding method. Because the two steel pipes have different welding methods, the performance is also different.
Three production processes of welded pipe
This time we mainly introduce welded steel pipe, that is, welded steel pipe. Its production is to bend the tube blank (steel plate and steel strip) into the required cross-section shape and size tube by various forming methods, and then weld the weld by different welding methods to get the steel pipe.
The influence of welded pipe blank width consumption
Welded pipe blank is the raw material for manufacturing welded pipe. Its mechanical properties and chemical composition have a far-reaching impact on the quality of welded pipe. Its width is an important factor to determine the weld strength. We usually say that the appropriate width of welded pipe blank refers to the width of a given thickness. The determination of the width is restricted by many factors.
