304 316 Stainless Coileg Steel Tubing
Stainless coileg steel tubing is the widely used steel capillary tube which is ideal for use in potentially corrosive environments or transferring liquids and gases for cooling, heating, and other purposes. Stainless coiled steel tubing is made with the finest quality stainless tube by bent, curved, wound, or otherwise formed process around a hollow “center”. Our stainless coiled steel tubing has the characteristics of restricted tolerance control, improved system ety and reliability, superior sealing performance, better corrosion resistance, etc. Tiptop supplies stainless coil tubing in extensive array of diameters and wall thicknesses and in various grades. We also offer custom fabrication of stainless coil tubing for your demands.
Applications
The stainless coiled steel tubing is widely used for industrial applications such as heat exchanger, boiler, petroleum, chemical, fertilizer, chemical, pharmaceutical, nuclear power, etc. It is also used as fluid transport system such as beer, milk, water systems, medical equipment, etc. Its other applications include mechanical structure, printing and dyeing, textile machinery, medical equipment, kitchen equipment, automobile and ship accessories, building and decoration, etc.
