S31603 / S30403 Stainless Steel Small Diameter Welded Marine
Multi-core Coiled Tubing
Mtsco’ s multi-core tubes are used for pneumatic and hydraulic
remote control, measuring and monitoring systems. materials are
ASTM TP316/ 316L, TP304/304L. The multi-core tube consists of one
to nine stainless steel tubes laid up spirally inside an extruded
outer PVC sheath. For easy identification and protection purposes
each individual tube is PVC sheathed in a different color. The
extruded outer sheath is made of oil and seawater resistant,
weatherproof, flame retardant, corrosion and acid resistant PVC.
The multi-core tube (outer sheath) is continuously marked at every
one meter throughout the entire length for easy installation. Heat
shrinkable products provide complete water sealing, abrasion and
corrosion protection under all conditions.
