Issues with socket welding of pressure pipelines
Thread Content
In the design and construction of pressure pipelines, for pipes of the same diameter, is it possible to avoid using equal-diameter tees and instead go straight to socket welding? ?
Do you mean a threaded tee? If it is a pressure pipeline, it is not recommended. But many non-chemical companies have been doing this all along
In the design and construction of pressure pipelines, due to material and structural constraints, it is generally not recommended to perform socket welding on pipes of the same diameter. Instead, equal-diameter tees should be used to ensure uniform and safe connections. Socket welding is commonly used for connecting pipes of different diameters. If socket welding must be used, it is necessary to comply with the corresponding welding standards and technical requirements. .
Socket welding is generally used for DN58 and below
It’s open welding; I guess many places do this unofficially, not following the standards strictly. These environments are generally low-temperature and low-pressure, and are non-toxic and harmless. In special situations where open welding is required and reinforcement is necessary, it’s better to use pipe fittings.
It seems there are no standard specifications regarding how the connections should be made, but the results of the welding must pass relevant tests or inspections. Such as strength tests, weld inspection, etc
