Seamless Stainless Steel Coil
Continuous seamless coil tubing for long-run fluid, gas and instrumentation lines.
Product Overview
Seamless stainless steel coil is produced by cold rolling and cold drawing into soft, bright-annealed coiled tubing. Because the whole run is delivered as a continuous coil, joints and fittings are minimized, which lowers leakage risk and installation cost.
It is widely used for instrumentation and control lines, chemical dosing lines, boiler and gas lines, heat exchangers and general fluid transfer where long continuous runs are required.
