Staonless Steel Coil Tube
Stainless steel coil heat exchangers are used in high heat applications such as heat exchangers, condensers and superheaters. These pipes are smaller in size and are used in coil form. Coil straighteners are used to fit coils into place. We are one of the leading stainless steel coil manufacturers and we produce coils in different material grades. Oshwin Overseas also manufactures coils in 304, 316, and other material grades. Our 304 stainless steel coiled tubing is the most cost-effective for many applications because raw materials are cheaper and widely available compared to other material grades.
ASTM A269 Seamless Coil Tube
4STM A269 stainless steel pipe is widely used in a variety of industrial and daily applications due to its versatility and high quality standards. Their excellent properties such as corrosion-resistant surface quality make them highly respected in a variety of industries, whether in high-end pharmaceutical environments or complex environments. In the chemical and petroleum engineering fields, these stainless steel pipes excel and are an integral part of numerous industries.

STM A29 304 stainless steel tubing is commonly used in hydraulics and instrumentation and is available in annealed brushed or bright annealed finishes upon request. Fractional sizes range from 1/8 inch to 5 inches, and metric tube sizes range from 3.17 mm to 127 mm. ASTM A269 304 Stainless Steel Pipe Over nominal wall thickness, seamless and welded austenitic stainless steel pipe suitable for general corrosion and low or high temperature applications, this is the universal standard for stainless steel pipe. Tubes are commonly used in structural machinery equipment. These Oioes can be made from austenitic steel under resistance welding, electrofusion welding or seamless drawing mechanism. SA269 is also available in different surface treatments and can be heat treated. SA 269 Tp 316 is more corrosion resistant than 304 materta type and is used in applications with high pressure and high temperature like low pressure and low temperature, so SA 269 to 304 and ASTM A269 To316 materta grades have different schedules. These tables correspond to different wall thicknesses corresponding to different nominal diameters.
