Step-by-Step Installation Guide
1.Fix M8/M10/M12 threaded rod onto upper structural channel or ceiling anchoring point in advance.
2.Wrap UTT41 formed steel loop around outer wall of target pipeline closely.
3.Screw flange nut and cup nut onto hanging threaded rod, hook loop onto nut assembly.
4.Rotate cup & flange nut oppositely to adjust pipeline vertical mounting height to design dimension.
5.Lock double nuts tightly after height confirmation to finish fixed suspension installation.
Industry Compliance
1.Full compliance with international MSS SP-58 & SP-69 Type7 pipe hanger manufacturing specification.
2.Pre-galvanized & electro-galvanized coating meet global anti-corrosion industry acceptance criteria.
3.Every finished piece passes factory dimension inspection and gravity load sampling test before delivery.
