Large-diameter steel wire spiral rubber hose (DN51-DN127) is typically used for high-flow main and return lines in metallurgical equipment, marine deck machinery, shield machines and large construction machinery.
Installation notes:
1. Keep the minimum bend radius — a tighter bend loads the wire layers unevenly and cuts impulse life sharply.
2. No torsion — never install the hose twisted; use an axial stripe on the cover to align.
3. Support and protection — long runs need clamps due to weight, plus guards near moving parts or hot surfaces.
4. Allow length margin — hose lengthens slightly under pressure; avoid permanent tension.
Xuantone large-diameter spiral hose covers DN51 to DN127 with flange, SAE flange and heavy-series fittings, customized to working conditions.
