What are the problems with the wall thickness of oxygen pipelines being thinner than that of elbows?
Thread Content
When the wall thickness of a pipe in a general medium is thinner than that of an elbow, grooving for welding can be carried out in accordance with the requirements of 50236. It has no impact on construction; will it have an impact on production safety?
This should be normal, right? We do this in our daily lives
Thank you all. According to legend, \"the inner diameter of the oxygen pipeline must be the same as that of the elbow; if there is a mismatch when connecting them, sparks can be generated, leading to an explosion.\" ”If the groove is prepared using method 50236, such a situation shouldn’t occur.
The inner diameters must be consistent to avoid the risk of turbulence caused by excessive flow speeds

There should be no problem, as long as the design requirements for pressure pipelines are met.
The inner wall thickness of pipe fittings is inevitably greater than that of their end walls. The inner walls of the main oxygen pipelines are smooth, free of sharp edges, burrs, or weld protrusions. It is also acceptable if the inner diameters are not identical; as long as the difference in wall thickness is not too large, and the diameter change between the larger and smaller ends is significant, it can still be used
