Must the elbows and tees on pipelines be standard components?

Can a homemade tee (the type where two pipes intersect perpendicularly) be used? Are there any corresponding standards? Thank you! As a supplementary note, the pipeline is DN65.
Standard components should be used for medium-pressure pipelines
GB12459, it’s necessary
If standard parts are available, why create them from scratch?
Standard components are proven to be reliable, whereas the reliability of self-made welded tees with openings cannot be verified, especially under such high-pressure conditions. For elbows, it is possible to consider bending the pipes, but they must also meet the standard requirements.
With such high pressure, calculations for reinforcement through openings show that a large thickness is required
It can be set on a timer for convenience, and it also helps save money
Safety comes first! ! ! :)
It’s not to save money – I made the tee myself with the inlets and outlets at the ends, and flanges were welded onto them. There wasn’t enough space for sensor probes; my pipes are DN65
At the import and export ends, flanges need to be welded on top; there isn’t enough space for sensor probes
You can’t skimp on this money; if something goes wrong, the cost will be far more than just the price of a three-way connection. A pressure of five or six kilograms, with a non-toxic and harmless medium – it’s possible to do this in that case. But for pressures in the dozens of kilograms, I advise you to follow the rules!
