Multi Core Tube Structure Schematism

Dong Nam’s Multi Core Tubes are spirally laid up and available with tubes in stainless steel, seamless and copper alloy. Straight bead welded, bright-annealed and calibrated high quality steel tubing. In order to easier identification and protection of tubes after installed, individual tubes are sheathed by PVC material of marked at every one meter throughout the entire length for easy installation. Extruded outer sheath is oil resistance, weather proof, flame-retardant, corrosion and acid resistant and physical/chemical protection.

▪ Tube material

▪ Sheath material
- Flame-retardant PVC, TPU, PE, Seawater and Oil Resistant, Halogen free material

▪ Standard length : 100-550m
- Longer length is available on special request.
▪ Approved by
- ABS, BV, CCS, DNVGL, KR, LR, NK, RINA, RMRS
