LNG Ship Marine Pipe Clamp Support Manufacturer

Shanghai Dolphin Marine Supporting Co.,Ltd. makes custom LNG pipe clamp supports, ISO 9001 and DNV-approved welding.

Shanghai Dolphin Marine Supporting Co.,Ltd. manufactures LNG ship pipe clamp supports and complete piping fixation systems for LNG and LEG carriers, FSRUs and offshore projects, all fabricated to vessel drawings.

The range covers ambient pipe clamp supports for general-service lines, cryogenic pipe clamps rated to -162°C for LNG and -104°C for LEG, U-bolt supports, quick-open clamps for maintenance-heavy lines, and hose brackets for ship-to-ship transfer. Each configuration is selected against the vessel's load cases and class requirements.

Cryogenic units use 316L Stainless Steel Marine Components with low-conductivity inserts to cut cold-bridge transfer, while Marine Steel Structural Parts use marine-grade steel with corrosion protection. Matching Marine Insulation Pad materials isolate contact points and prevent galvanic corrosion.

Manufacturing stays in one workshop: forming, welding, machining and inspection. Our quality system follows ISO 9001, our welding workshop holds DNV approval, and every batch is checked against drawings before packing. Pipe diameter, bolt spacing, base plate size and insulation gap all come from your drawing.

For newbuilds, drawings are exchanged early so production can be planned; for retrofits, we work from measurements of the existing vessel. Whether you need a single Marine Pipe Clamp Support or a complete LNG Vessel Cryogenic Pipe Support package, the same process applies — send your drawings and we confirm materials, dimensions and delivery before production.

Backed by ISO 9001 management and DNV-approved welding, our Cryogenic Pipeline Components serve low-temperature marine piping year after year.
