Stainless Steel Capillary Tube/pipe
Capillary tubes are most commonly made of stainless steel, acid resistant, heat-resistant, creep resistant materials, special alloys, nickel, titanium, and other non-ferrous metals. Such as : Inconel, Monel, Hastelloy, Copper, Brass, Nickel, Copper-nickel alloys, Copper alloys, nickel alloys, duplex stainless steel and other types of steels.
Stainless steel capillary tube/pipe are resistant to high temperature steam, impact and corrosion; anti-fouling, not easy to stain, anti-oxidation and corrosion, long service life, reduce maintenance time, save costs: and the tube installation process is good, safe and reliable, and the tube wall is uniform Features.
Small diameter stainless steel pipe/tube Applications: Stainless steel capillary coils are widely used in oil drilling, complete sets of equipment (pipelines and cables), chemical industry, pharmaceuticals, food, machinery, hardware, healthcare, boiler gas, plumbing accessories, shipbuilding and other industries, heat exchangers and cold treatment in the chemical industry , gas pipelines, etc.
