U‑TUBES WITH
ROUND BEND

We offer you U‑tubes with round bend which can be used for very dif­fe­rent appli­ca­tions. The U‑tubes are sup­plied as 180° ver­sion accor­ding to the customer’s spe­ci­fi­ca­tions, made of seam­less or welded tubes, manu­fac­tu­ring com­plies with appli­cable stan­dard spe­ci­fi­ca­tions and is car­ried out with hig­hest pre­cision. Our pro­cesses ensure the pos­si­bi­lity to imple­ment a wide variety of our final cus­to­mers’ spe­ci­fi­ca­tions as well as non-stan­dard designs made of steels, stain­less steels and spe­cial alloys. If requested, we also imple­ment accep­tances which are related to the manu­fac­tu­ring of the pro­ducts as well as tech­no­lo­gical and mecha­nical tests.
