Hi everyone,
I'm not sure if there's an official process for sanitary pipe. But does it require filler (for procedure). The attached photo was pulse welded 1.5mm using no filler but is used for extraction.
Yeah... Do need more practice on pipe these jobs don't come through very often.
But I've seen some people using filler and others fusion welding.
Is there a right or wrong way?
This is a question based on zero experience: does the finish/appearance of the _inside_ of the pipe form any part of the sanitary standards? Can you infer what the inside will look like from seeing the outside?
