MTSCO is a leading manufacturer who is specialized in seamless
coiled tubing produce . Stainless steel seamless coiled tubing
final surface is bright annealed. According to standard very
strictly, tubes which produced by us always have correct OD and WT
tolerance. They are very popular in military, semiconductor,
pharmaceutical biotechnology, precision instruments, hydraulic
parts, chemicals industry, boilers and heat exchangers, aerospace
industry, automotive industry, electronics, petroleum exploration,
precision machinery, rail transportation, shipbuilding plants,
air-conditioning industry, solar industry, water heater industry
etc. They can be used in many others industries also .
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.
