Buttweld 5D bend are often chosen for applications where space is limited but where a gentler curve is needed to maintain the integrity and flow efficiency of the pipeline. This radius helps reduce stress on the piping system and improves overall performance, making it a popular choice for industries like oil and gas, petrochemical, and water treatment.
